The Perfect Server - Mandriva 2007 Spring Free - Page 4
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 Configure Additional IP Addresses
(This step is totally optional and is needed only if you want to add more IP addresses to your network interface eth0!)
Let's assume our network interface is eth0. Then there is a file /etc/sysconfig/network-scripts/ifcfg-eth0 which looks like this:
cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0 BOOTPROTO=static IPADDR=192.168.0.100 NETMASK=255.255.255.0 GATEWAY=192.168.0.1 ONBOOT=yes METRIC=10 MII_NOT_SUPPORTED=no USERCTL=no DNS1=145.253.2.75 DNS2=193.174.32.18 RESOLV_MODS=yes IPV6INIT=no IPV6TO4INIT=no |
Now we want to create the virtual interface eth0:0 with the IP address 192.168.0.101. All we have to do is to create the file /etc/sysconfig/network-scripts/ifcfg-eth0:0 which looks like this:
vi /etc/sysconfig/network-scripts/ifcfg-eth0:0
DEVICE=eth0:0 BOOTPROTO=static IPADDR=192.168.0.101 NETMASK=255.255.255.0 GATEWAY=192.168.0.1 ONBOOT=yes METRIC=10 MII_NOT_SUPPORTED=no USERCTL=no MS_DNS1=145.253.2.75 MS_DNS2=193.174.32.18 RESOLV_MODS=yes IPV6INIT=no IPV6TO4INIT=no |
Afterwards we have to restart the network:
/etc/init.d/network restart
You might also want to adjust /etc/hosts after you have added new IP addresses, although this is not necessary.
Now let's run
ifconfig
to see if our new IP address is working. The output should look like this:
[root@server1 ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:29:EC:09:F4
inet addr:192.168.0.100 Bcast:192.168.0.255 Mask:255.255.255.0

RX bytes:6508 (6.3 KiB) TX bytes:6508 (6.3 KiB)
6 Setting The Hostname
(This step is also 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
7 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:
For me the wizard gave back these commands that I run on the command line:
urpmi.addmedia main ftp://ftp.tu-chemnitz.de/pub/linux/mandrakelinux/official/2007.1/i586/media/main/release with media_info/hdlist.cz
urpmi.addmedia --update main_updates ftp://ftp.tu-chemnitz.de/pub/linux/mandrakelinux/official/2007.1/i586/media/main/updates with media_info/hdlist.cz
urpmi.addmedia contrib ftp://ftp.tu-chemnitz.de/pub/linux/mandrakelinux/official/2007.1/i586/media/contrib/release with media_info/hdlist.cz
urpmi.addmedia --update contrib_updates ftp://ftp.tu-chemnitz.de/pub/linux/mandrakelinux/official/2007.1/i586/media/contrib/updates with media_info/hdlist.cz
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 2007 Spring 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
8 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++
9 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
/dev/sda6 / ext3 defaults,usrquota,grpquota 1 1 /dev/sda1 /boot ext3 defaults 1 2 /dev/hdc /media/cdrom auto umask=0,users,iocharset=utf8,noauto,ro,exec 0 0 none /media/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,umask=0,iocharset=utf8,sync 0 0 none /proc proc defaults 0 0 /dev/sda5 swap swap defaults 0 0 |
Then run:
touch /aquota.user /aquota.group
chmod 600 /aquota.*
mount -o remount /
quotacheck -avugm
quotaon -avug
10 DNS Server
To install The BIND DNS server, run:
urpmi bind
Mandriva 2007 Spring'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
Then start BIND:
/etc/init.d/named start
