4 Adjust /etc/hosts

Next we edit /etc/hosts. Make it look like this:

vi /etc/hosts

127.0.0.1               localhost.localdomain localhost
192.168.0.100           server1.example.com server1

 

5 Setting The Hostname

(This step is optional.)

This is not necessary if you have set the correct hostname during the installation. You can check the current hostname with the commands

hostname
hostname -f

Both commands should show server1.example.com.

If the output shows a wrong hostname, you can set the correct one like this:

echo server1.example.com > /etc/hostname
/bin/hostname -F /etc/hostname

 

6 Configure urpmi

You can use the wizard on http://easyurpmi.zarb.org/ to find out how to configure urpmi so that urpmi uses online package repositories:

(When I wrote this tutorial, Mandriva 2009.0 was not yet available in the wizard, so I chose 2008.1 and then replaced 2008.1 with 2009.0 in the urpmi commands. You can do the same, but the wizard should be up-to-date in a few days.)

For me the wizard gave back these commands that I run on the command line:

urpmi.addmedia 'Main' 'http://ftp.free.fr/mirrors/ftp.mandriva.com/MandrivaLinux/official/2009.0/i586/media/main/release'

urpmi.addmedia 'Contrib' 'http://ftp.free.fr/mirrors/ftp.mandriva.com/MandrivaLinux/official/2009.0/i586/media/contrib/release'

urpmi.addmedia 'Main Updates' 'http://ftp.free.fr/mirrors/ftp.mandriva.com/MandrivaLinux/official/2009.0/i586/media/main/updates'

urpmi.addmedia 'Contrib Updates' 'http://ftp.free.fr/mirrors/ftp.mandriva.com/MandrivaLinux/official/2009.0/i586/media/contrib/updates'

 

6.1 Disable The Installation Media

Disabling the installation media is particularly useful if your server will be in a remote location where you cannot insert the DVD/CDs. To disable the installation media (the Mandriva DVD or the CDs), we must first find out their internal names. We can do this by running

ls -l /var/lib/urpmi/

[root@server1 ~]# ls -l /var/lib/urpmi/
total 25980
-rw-r--r-- 1 root root     9791 2008-10-09 17:14 compssUsers.flat
drwxr-xr-x 2 root root     4096 2008-10-09 15:32 Contrib/
drwxr-xr-x 2 root root     4096 2008-10-09 15:32 Contrib Updates/

-rw-r--r-- 1 root root 22476876 2008-10-09 17:05 hdlist.Mandriva Linux - 2009.0 (Free) - Installer.cz

[root@server1 ~]#

You can take the correct names from the names.* entries. So to disable the Mandriva 2009 DVD, I run

urpmi.removemedia "Mandriva Linux - 2009.0 (Free) - Installer"
urpmi.removemedia "Mandriva Linux - 2009.0 (Free) - Installer (contrib)"

For the CDs, the command will be slightly different - just take a look at the names.* entries on your system.

 

6.2 Creating An Auto-Update Script

Now we create a script /etc/cron.daily/software_update that will autmatically be run by cron daily and looks for and installs the latest software updates on your Mandriva 2009.0 system. The script looks like this:

vi /etc/cron.daily/software_update

#!/bin/bash
urpmi.update updates
urpmi --auto --update --auto-select

Make the script executable:

chmod 755 /etc/cron.daily/software_update

 

7 Install Some Packages

Now we install a few packages that are needed later on:

urpmi fetchmail wget bzip2 unzip zip nmap openssl lynx fileutils ncftp flex libxorg-x11-devel gcc gcc-c++

 

8 Quota

To install the quota package, run

urpmi quota

Edit /etc/fstab to look like this (I added ,usrquota,grpquota to the partition with the mount point /):

vi /etc/fstab

# Entry for /dev/sda6 :
UUID=b258edec-9613-11dd-99c4-457f04a19dca / ext3 relatime,usrquota,grpquota 1 1
# Entry for /dev/sda1 :
UUID=b6fa1e84-9613-11dd-84e1-bf4bbb042d23 /boot ext3 relatime 1 2
/dev/fd0 /media/floppy auto umask=0,users,iocharset=utf8,noauto,exec,flush 0 0
none /proc proc defaults 0 0
# Entry for /dev/sda5 :
UUID=b748b6b6-9613-11dd-844e-fba510a12ad6 swap swap defaults 0 0

Then run:

touch /aquota.user /aquota.group
chmod 600 /aquota.*
mount -o remount /
quotacheck -avugm
quotaon -avug

 

9 DNS Server

To install the BIND DNS server, run:

urpmi bind

Mandriva 2009.0's BIND is running chrooted by default, therefore we need to create a few symlinks so that ISPConfig (if you want to install it) can deal with it:

cd /var/lib/named/var
mkdir -p lib/named/var
cd lib/named/var
ln -s ../../../named/ named
ln -s ../../../run/ run
cp /var/lib/named/var/named/reverse/named.local /var/lib/named/var/named/

Next we create the system startup links for BIND...

chkconfig named on

... and start it:

/etc/init.d/named start

1. to add a media, you can do it easily with 1 line, without the need to use easyurpmi :

 urpmi.addmedia --distrib --mirrorlist

This command will automatically add all the remote FTP repositories, and will try to select the closest mirror for you. So if you want to only have remote repositories and removed the installation media, you'd better remove all the media/repositories, and then add the new ones :

 urpmi.removemedia -a && urpmi.addmedia --distrib --mirrorlist

2. if you want to do automatic updates, but only install packages from the updates repositories, you can now use --auto-update which will do at the same time a "urpmi.update -a" and a "urpmi --auto-select". So you auto-update script could look like this :

urpmi --auto-update --update  --auto

I use a script that also includes the "--wait-lock" option so that the script will wait if another instance of urpmi happens to be running and has locked the database.
