Introduction Mandriva Linux (formerly Mandrakelinux or Mandrake Linux) is a French Linux distribution distributed by Mandriva (formerly Mandrakesoft). It uses the RPM Package Manager. The product lifetime of Mandriva Linux releases is 18 months for base updates (Linux, system software, etc.) and 12 months for desktop updates (window managers, desktop environments, web browsers, etc.). Server products receive full updates for at least 24 months after their release. Mandriva Linux contains the Mandriva Control Center, which eases configuration of some settings. It has many programs known as Drakes or Draks, collectively named drakxtools, to configure many different settings. Examples include MouseDrake to set up a mouse, DiskDrake to set up disk partitions and drakconnect to set up a network connection. They are written using GTK+ and Perl, and most of them can run in both graphical and text mode using the ncurses interface.
Hands-on Lab Solution: In this Hands-on Lab session, you’ll learn how to setup virtual network on VMware (you may also use any other virtual machines like MS VirtualPC, Linux Xen, or VirtualBox from Oracle, or Citrix XenServer). In this lab session, we’ll concentrate on installing Mandriva Linux 2010 Spring server which you can then later use to install any other applications as desired. After completing the initial installation I’ll show you how to install DNS server, LAMP server, and Samba file server. You will also learn how to install and secure SFTP using TSL and finally install and secure MySQL database server. You’ll also have opportunity to learn some troubleshooting techniques and also do some lab assignments at the end of the lab session.
Part 1: Install & Upgrade Mandriva 2010
Step 2: Install Mandriva Linux 2010 Spring 1. Hope over to http://wiki.mandriva.com/en/ website and the Mandriva Linux 2010 Spring 32bit ISO server, which at the time of writing this lab manual was " mandriva-linux-one-2010spring-GNOME-europe-americas-cdrom-i586.iso" 2. Once you have ed the Mandriva ISO specific to your distribution, you have the option of burning it into CD or just by using the ISO package to install it from your virtual machine, in our case VMware. 3. Fire-up a new virtual machine and perform the initial configuration and setup to use ISO package.

6. You’re done with this section.
Step 3: Change/Set System’s Hostname In this section we’re going to change the computer hostname. But first let’s check the current hostname. 1. To check the current hostname issue "hostname" command, as shown in Fig. 28. which shows the current hostname is: : "localhost"
Fig. 28: Current hostname: "localhost"
2. Next, we’re going to change the hostname to: "server01.govtestlabs.com". To do so, change to the directory "/etc/sysconfig" and use your favorite Text editor to edit the "network" file. [root@localhost ~]# gedit /etc/sysconfig/network

Add a line containing “short hostname” as follows: HOSTNAME=server01
Fig.29
Note 1: The "short hostname" (what you see at the bash prompt) is the leftmost segment of a fully qualified domain name (FQDN). If the FQDN is your.domain.com, the hostname (the short name) would be "your". Note 2: that you do not specify the FQDN with the HOSTNAME variable, it is not even possible. Quoting the manpage of hostname (the tool that is used to set the hostname): You can't change the FQDN (as returned by hostname --fqdn) or the DNS domain name (as returned by dnsdomainname) with this command. Note 3: the FQDN/DNS domain name is configured in /etc/hosts by default (unless a more elaborate method like DNS or NIS are used to configure the hostnames – the order in which methods are tried is defined in /etc/host.conf file) 3. Next in the /etc/hosts file I changed the "127.0.0.1 localhost" to: 127.0.0.1
server01 localhost
7. Reboot the system for the changes to take effect. Or if you want to continue working and restart the system latter, then you can alternatively issue the command [root@localhost ~]# /etc/init.d/network restart 8. Next, from the Terminal window, issue the "hostname" command to view our new hostname, as shown in Fig. 30, and which correctly returns our new hostname.

Fig. 30 9. You’re done with this section.
Step 4: Modify the Hosts file toe set FQDN In this step we want to modify the hosts file to reflect our new "Fully Qualified Domain Name" and IP address. To do this, from the Terminal window issue the command: 1. Using you favorite Text editor, edit your /etc/hosts file, adding both the long & short names to the 127.0.0.1 line, like so (the FQDN is only needed if you're actually part of the network of the FQDN. If you just want to name your computer something different than "localhost", then the short-name is all you need to configure): 127.0.0.1
localhost your.fully.qualified.hostname your
2. If you are configured for a static IP address on your network interface, leave the 127.0.0.1 line alone, and instead create a new line in the hosts file that links the names to that static IP address, like so: 127.0.0.1 192.168.1.2
localhost your.fully.qualified.hostname your
Note: one side benefit of this latter method is that you can put every system on your static-IP-based LAN into the file in this fashion, and then use a copy of that same /etc/hosts file on every one of them. 3. In our case, we have: [root@server01 ~]# gedit /etc/hosts And add the following line, as shown in Fig. 31: 127.0.0.1
localhost server01.govtestlabs.com servver01

4. Next edit the Hosts file using your favorite Text editor, as shown in Fig. 31(b). Save & Exit.
Fig. 31b: Modified Hosts file. Save & close. Note: So now the Hostname or Fully Qualified Hostname is: "server01.govtestlabs.com"
5. For the final test, issue the ping command, to see if our hostname can return its own localhost IP address (see Fig. 32): [root@server01 ~]# ping server01.govtestlabs.com
Fig. 32: Ping test. (Note: Hit "Ctrl C" to break the ping test)

Managing s via Command-line Although most Linux distros comes with excellent graphical tool to manage your s (system-configs), there are times, for example when istering a server through SSH, that management has to be done from command line. All operations can be done using the following commands: id, add, mod, del, groupadd, groupdel, groupmod, wd These exist in every Linux distribution with slight differences in each command’s ed options. The following info applies to Fedora and other Red Had based distros like CentOS and Mandriva.
Step 1: Create New s via Command-line 1. To create a , run add command: # add –c "My Example " name In this case, let add krabah: © April 2007, Kefa Rabah, Global Technology Solutions Institute, Vancouver Canada

Step 2: Change the ’s 1. To change a ’s : # wd name 2. If it’s used without specifying a name, then the currently logged in ’s is changed. 3. You’re done with this section.
Step 3: Add a to a group 1. mod is used to modify a ’s settings. Check the man page for all the available options. One useful use of this command is to add a to a group: # mod -a -G group1 name Note: the -a option is critical. The is added to group1 while he continues to be a member of other groups. If it’s not used, then the is added only to group1 and removed from any other groups. So, take note! 2. You’re done with this section.
Step 4: Remove a from a group 1. Removing a from a group is a bit trickier. Unfortunately, there is no direct command, at least not in most Linux distros, that can do that from command line. At first you need to get a list of groups that your is a member of: © April 2007, Kefa Rabah, Global Technology Solutions Institute, Vancouver Canada

# id -nG name group1 group2 group3 .... 2. Then you need to put all these groups as a comma-separated list to the "mod -G" option, except for the group from which you want the to be removed. So, to remove the from group2, issue the command: # mod -G group1,group3,... name 3. You’re done with this section.
Step 5: Lock and Unlock s 1. Other common mod uses are to lock and unlock s. To lock out a : # mod -L name 2. To unlock the : # mod -U name 4. You’re done with this section.
Step 6: Delete a 1. del is used to delete a . If the -r option is used then the ’s home directory and mail spool are deleted too: # del -r name 5. You’re done with this section.
Step 7: Create a new group 1. To create a new group, issue the command: # groupadd groupname Note: the -r option can be used to create a group with GID<500 (system). 2. You’re done with this section.
Step 8: Change a group’s name 1. Groupmod can be used to change a group name: © April 2007, Kefa Rabah, Global Technology Solutions Institute, Vancouver Canada

Part 4: Mandriva URPMI Utility
Step 1: Mandriva: urpm 1. Mandriva Linux (formerly Mandrake and Connectiva) has a toolset similar to APT called urpmi. To install software perform the following commands: ]# urpmi packagename 2. To remove software: # urpme packagename 3. To update the local package database: # urpmi.update -a 4. To install security updates and bug fixes: # urpmi --auto-select Note: for a more in-depth yum tutorial and other resources, see Managing Software with urpm. 5. You’re done with this section.

Part 5: Install OpenSSH Package In order to secure remote connections to your server, you will need to install the OpenSSH package. This package will come in handy in the future to istrative tasks on the system. By default this package is already installed in the Mandriva server option. 1. To install OpenSSH, issue the following command: # urpmi openssh -y 2. Now check the status of sshd daemon, if stopped then start it:
Fig. 35
3. To to a remote computer that is running OpenSSH, you use the ssh name@hostname command, replacing name with a valid name on the computer you are trying to to, and replacing hostname with either the fully qualified host name (e.g. example.com) of your server, or it’s IP address (e.g. 192.168.83.190).

Part 6: Installing and Configuring Apache 2 and Webmin istering Linux and Unix-based servers does not need to be the scourge of your work day. With a handy tool called Webmin as part of your arsenal, you can regain full control of your servers’ setup and configuration via the Web browser. Webmin is the most powerful istration tool in its nature. You can use it, for example, to setup DNS Server, but I will not go over it in detail because you will learn more about it in the coming modules. It is not difficult to use Webmin because it is web based, in any event, you should also know that you can use it remotely to istrate your network servers.
Step 1: Install Web server ("httpd") daemon As you may recall, we didn’t install any server during the initial installation stage, however, now we do require a Webserver to be running to test our Webmin installation. 1. To install a Web server daemon ("httpd"), perform the following procedure (as root ): # urpmi -a apache2 -y Note: switch -a will ensure that all the dependencies are installed. 5. Now check the status of httpd daemon, if stopped then start it:
Fig. 37
Step 1: Install Webmin 1. To Install Webmin and get started, drop by www.webmin.com and the latest release. You can use RPMs for RHE/CentOS and related systems that binary installations or you can build Webmin from source. Webmin also s a large number of UNIX variants, including Mac OS X. 2. You’ll be prompted to install the Webmin package as shown in Fig. 38, click on the Install button to install it. © April 2007, Kefa Rabah, Global Technology Solutions Institute, Vancouver Canada

12. You’re done with this section.
Step 2: Installing MySQL Database Server Installing MySQL database server is always necessary if you are running a database driven ecommerce site. running mysql server to a fair extend requires at least 256MB of RAM in your server. So unless you are running database driven sites you don’t absolutely need MySQL. 1. Again if you didn’t pre-install the MySQL database server, then no worries - the following commands will install mysql 5 server and mysql 5 client. # urpmi mysql
-y
Note: the configuration file of mysql is located at: /etc/mysql/my.cnf Warning! By default there is no root set for MySQL and it is important to set the for the ROOT .
2.1 Manually Creating s to use MySQL and Changing Root 2. By default mysql creates as root and runs with no port. You might need to setup the root . 3. To setup MySQL , run: # /usr/bin/mysql -u root 'new-' Note: alternatively, you use the following command: mysql -u root mysql> USE mysql; mysql> UPDATE SET =('new-') WHERE ='root'; mysql> FLUSH PRIVILEGES; Note: you must never use root , so you might need to create a to connect to mysql database for a PHP script. Alternatively you can add s to mysql database by using a control like Webmin or phpMy to easily create or assign database permission to s. We will install Webmin and phpmy during later once we complete basic installation. 4. You can also try remote localhost as "root" , as follows: # mysql -h localhost -u root -p

1. Now let’s and create "datactrbk" database and "net" , as follows: # mysql -u root -p > CREATE DATABASE datactrbk DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci; > GRANT ALL PRIVILEGES ON datactrbk.* TO 'net'@'localhost' IDENTIFIED BY ''; > GRANT SELECT, LOCK TABLES ON datactrbk.* TO 'net'@'localhost' IDENTIFIED BY ''; > FLUSH PRIVILEGES; > QUIT
Note: The above also creates a backup "net" so that you can use mysqldump to make database backups without accident. 2. Now let’s test the for "net" , as follows: net@server01:~$ mysql -u net -p Enter : mysql> SHOW DATABASES; +--------------------+ | Database

Step 3: Install phpMy PhpMy is a nice web based database management and istration software and easy to install and configure under apache. Managing databases with tables couldn’t be much simpler by using phpMy. 6. You can down and install phpMy from here. When done ing you’ll be prompted to install it as shown in Fig. 46:
Fig. 46
Note 1: you may be prompted to install dependencies’. Note 2: you’ll be prompted to choose the webserver phpMy you will use, as shown in Fig. 47. Note: to manually set up under Apache all you need to do is include the following line in /etc/apache2/apache2.conf: Include /etc/phpmy/apache.conf Note: the phpmy configuration file is located at: /etc/phpmy folder. 7. Now restart Apache: /etc/init.d/apache2 restart 8. Next, fire-up your browser and point it to: http://your-domain/phpmy. with appropriate MySQL database with appropriate privileges, see Fig. 47.

Step-By-Step Install Guide Mandriva Linux 2010 Spring By Kefa Rabah, [email protected]
Dec 13, 2010
GTS Institute
Introduction Mandriva Linux (formerly Mandrakelinux or Mandrake Linux) is a French Linux distribution distributed by Mandriva (formerly Mandrakesoft). It uses the RPM Package Manager. The product lifetime of Mandriva Linux releases is 18 months for base updates (Linux, system software, etc.) and 12 months for desktop updates (window managers, desktop environments, web browsers, etc.). Server products receive full updates for at least 24 months after their release. Mandriva Linux contains the Mandriva Control Center, which eases configuration of some settings. It has many programs known as Drakes or Draks, collectively named drakxtools, to configure many different settings. Examples include MouseDrake to set up a mouse, DiskDrake to set up disk partitions and drakconnect to set up a network connection. They are written using GTK+ and Perl, and most of them can run in both graphical and text mode using the ncurses interface.
Hands-on Lab Solution: In this Hands-on Lab session, you’ll learn how to setup virtual network on VMware (you may also use any other virtual machines like MS VirtualPC, Linux Xen, or VirtualBox from Oracle, or Citrix XenServer). In this lab session, we’ll concentrate on installing Mandriva Linux 2010 Spring server which you can then later use to install any other applications as desired. After completing the initial installation I’ll show you how to install DNS server, LAMP server, and Samba file server. You will also learn how to install and secure SFTP using TSL and finally install and secure MySQL database server. You’ll also have opportunity to learn some troubleshooting techniques and also do some lab assignments at the end of the lab session.
Part 1: Install & Upgrade Mandriva 2010
Step 2: Install Mandriva Linux 2010 Spring 1. Hope over to http://wiki.mandriva.com/en/ website and the Mandriva Linux 2010 Spring 32bit ISO server, which at the time of writing this lab manual was " mandriva-linux-one-2010spring-GNOME-europe-americas-cdrom-i586.iso" 2. Once you have ed the Mandriva ISO specific to your distribution, you have the option of burning it into CD or just by using the ISO package to install it from your virtual machine, in our case VMware. 3. Fire-up a new virtual machine and perform the initial configuration and setup to use ISO package.

6. You’re done with this section.
Step 3: Change/Set System’s Hostname In this section we’re going to change the computer hostname. But first let’s check the current hostname. 1. To check the current hostname issue "hostname" command, as shown in Fig. 28. which shows the current hostname is: : "localhost"
Fig. 28: Current hostname: "localhost"
2. Next, we’re going to change the hostname to: "server01.govtestlabs.com". To do so, change to the directory "/etc/sysconfig" and use your favorite Text editor to edit the "network" file. [root@localhost ~]# gedit /etc/sysconfig/network

Add a line containing “short hostname” as follows: HOSTNAME=server01
Fig.29
Note 1: The "short hostname" (what you see at the bash prompt) is the leftmost segment of a fully qualified domain name (FQDN). If the FQDN is your.domain.com, the hostname (the short name) would be "your". Note 2: that you do not specify the FQDN with the HOSTNAME variable, it is not even possible. Quoting the manpage of hostname (the tool that is used to set the hostname): You can't change the FQDN (as returned by hostname --fqdn) or the DNS domain name (as returned by dnsdomainname) with this command. Note 3: the FQDN/DNS domain name is configured in /etc/hosts by default (unless a more elaborate method like DNS or NIS are used to configure the hostnames – the order in which methods are tried is defined in /etc/host.conf file) 3. Next in the /etc/hosts file I changed the "127.0.0.1 localhost" to: 127.0.0.1
server01 localhost
7. Reboot the system for the changes to take effect. Or if you want to continue working and restart the system latter, then you can alternatively issue the command [root@localhost ~]# /etc/init.d/network restart 8. Next, from the Terminal window, issue the "hostname" command to view our new hostname, as shown in Fig. 30, and which correctly returns our new hostname.

Fig. 30 9. You’re done with this section.
Step 4: Modify the Hosts file toe set FQDN In this step we want to modify the hosts file to reflect our new "Fully Qualified Domain Name" and IP address. To do this, from the Terminal window issue the command: 1. Using you favorite Text editor, edit your /etc/hosts file, adding both the long & short names to the 127.0.0.1 line, like so (the FQDN is only needed if you're actually part of the network of the FQDN. If you just want to name your computer something different than "localhost", then the short-name is all you need to configure): 127.0.0.1
localhost your.fully.qualified.hostname your
2. If you are configured for a static IP address on your network interface, leave the 127.0.0.1 line alone, and instead create a new line in the hosts file that links the names to that static IP address, like so: 127.0.0.1 192.168.1.2
localhost your.fully.qualified.hostname your
Note: one side benefit of this latter method is that you can put every system on your static-IP-based LAN into the file in this fashion, and then use a copy of that same /etc/hosts file on every one of them. 3. In our case, we have: [root@server01 ~]# gedit /etc/hosts And add the following line, as shown in Fig. 31: 127.0.0.1
localhost server01.govtestlabs.com servver01

Managing s via Command-line Although most Linux distros comes with excellent graphical tool to manage your s (system-configs), there are times, for example when istering a server through SSH, that management has to be done from command line. All operations can be done using the following commands: id, add, mod, del, groupadd, groupdel, groupmod, wd These exist in every Linux distribution with slight differences in each command’s ed options. The following info applies to Fedora and other Red Had based distros like CentOS and Mandriva.

If it’s not used, then the is added only to group1 and removed from any other groups. So, take note! 2. You’re done with this section.
Step 4: Remove a from a group 1. Removing a from a group is a bit trickier. Unfortunately, there is no direct command, at least not in most Linux distros, that can do that from command line.

Part 5: Install OpenSSH Package In order to secure remote connections to your server, you will need to install the OpenSSH package. This package will come in handy in the future to istrative tasks on the system. By default this package is already installed in the Mandriva server option. 1. To install OpenSSH, issue the following command: # urpmi openssh -y 2. Now check the status of sshd daemon, if stopped then start it:

Part 6: Installing and Configuring Apache 2 and Webmin istering Linux and Unix-based servers does not need to be the scourge of your work day. With a handy tool called Webmin as part of your arsenal, you can regain full control of your servers’ setup and configuration via the Web browser. Webmin is the most powerful istration tool in its nature. You can use it, for example, to setup DNS Server, but I will not go over it in detail because you will learn more about it in the coming modules. It is not difficult to use Webmin because it is web based, in any event, you should also know that you can use it remotely to istrate your network servers.
Step 1: Install Web server ("httpd") daemon As you may recall, we didn’t install any server during the initial installation stage, however, now we do require a Webserver to be running to test our Webmin installation. 1. To install a Web server daemon ("httpd"), perform the following procedure (as root ): # urpmi -a apache2 -y Note: switch -a will ensure that all the dependencies are installed. 5. Now check the status of httpd daemon, if stopped then start it:
Fig. 37
Step 1: Install Webmin 1. To Install Webmin and get started, drop by www.webmin.com and the latest release. You can use RPMs for RHE/CentOS and related systems that binary installations or you can build Webmin from source. Webmin also s a large number of UNIX variants, including Mac OS X. 2. You’ll be prompted to install the Webmin package as shown in Fig. 38, click on the Install button to install it. © April 2007, Kefa Rabah, Global Technology Solutions Institute, Vancouver Canada

Step 2: Installing MySQL Database Server Installing MySQL database server is always necessary if you are running a database driven ecommerce site. running mysql server to a fair extend requires at least 256MB of RAM in your server. So unless you are running database driven sites you don’t absolutely need MySQL. 1. Again if you didn’t pre-install the MySQL database server, then no worries - the following commands will install mysql 5 server and mysql 5 client. # urpmi mysql
-y
Note: the configuration file of mysql is located at: /etc/mysql/my.cnf Warning! By default there is no root set for MySQL and it is important to set the for the ROOT .
2.1 Manually Creating s to use MySQL and Changing Root 2. By default mysql creates as root and runs with no port. You might need to setup the root . 3. To setup MySQL , run: # /usr/bin/mysql -u root 'new-' Note: alternatively, you use the following command: mysql -u root mysql> USE mysql; mysql> UPDATE SET =('new-') WHERE ='root'; mysql> FLUSH PRIVILEGES; Note: you must never use root , so you might need to create a to connect to mysql database for a PHP script. Alternatively you can add s to mysql database by using a control like Webmin or phpMy to easily create or assign database permission to s. We will install Webmin and phpmy during later once we complete basic installation. 4. You can also try remote localhost as "root" , as follows: # mysql -h localhost -u root -p
