The Perfect Server - Fedora 14 x86_64 [ISPConfig 2] - Page 3

4 Adjust /etc/hosts

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

vi /etc/hosts
127.0.0.1       localhost.localdomain   localhost       localhost4
192.168.0.100   server1.example.com     server1
::1     server1.example.com     server1 localhost localhost.localdomain localhost6.localdomain6 localhost6

It is important that you add a line for server1.example.com and remove server1.example.com and server1 from the 127.0.0.1 line.

 

5 Disable SELinux

SELinux is a security extension of Fedora that should provide extended security. In my opinion you don't need it to configure a secure system, and it usually causes more problems than advantages (think of it after you have done a week of trouble-shooting because some service wasn't working as expected, and then you find out that everything was ok, only SELinux was causing the problem). Therefore I disable it (this is a must if you want to install ISPConfig later on).

Edit /etc/selinux/config and set SELINUX=disabled:

vi /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

Afterwards we must reboot the system:

reboot

 

6 Install Some Software

Next we update our existing packages on the system:

yum update

Now we install some software packages that are needed later on:

yum install fetchmail wget bzip2 unzip zip nmap openssl lynx fileutils ncftp gcc gcc-c++

 

7 Journaled Quota

(If you have chosen a different partitioning scheme than I did, you must adjust this chapter so that quota applies to the partitions where you need it.)

To install quota, we run this command:

yum install quota

Edit /etc/fstab and add ,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0 to the / partition (/dev/mapper/vg_server1-lv_root):

vi /etc/fstab
#
# /etc/fstab
# Created by anaconda on Thu Nov  4 01:49:41 2010
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
/dev/mapper/vg_server1-lv_root /                       ext4    defaults,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0        1 1
UUID=1b6ac184-dcd8-4cc9-829f-d5fca50df46f /boot                   ext4    defaults        1 2
/dev/mapper/vg_server1-lv_swap swap                    swap    defaults        0 0
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0

Then run

touch /aquota.user /aquota.group
chmod 600 /aquota.*
mount -o remount /

quotacheck -avugm
quotaon -avug

to enable quota.

 

8 Install A Chrooted DNS Server (BIND9)

To install a chrooted BIND9, we do this:

yum install bind-chroot

Next, we change a few permissions:

chmod 755 /var/named/
chmod 775 /var/named/chroot/
chmod 775 /var/named/chroot/var/
chmod 775 /var/named/chroot/var/named/
chmod 775 /var/named/chroot/var/run/
chmod 777 /var/named/chroot/var/run/named/
cd /var/named/chroot/var/named/
ln -s ../../ chroot

Then we open /etc/sysconfig/named and make sure that it has the following line to tell BIND that it's running chrooted in /var/named/chroot:

vi /etc/sysconfig/named
[...]
ROOTDIR=/var/named/chroot

Next open /etc/rsyslog.conf...

vi /etc/rsyslog.conf

... and add the line $AddUnixListenSocket /var/named/chroot/dev/log to it:

[...]
$AddUnixListenSocket /var/named/chroot/dev/log

Restart rsyslog:

/etc/init.d/rsyslog restart  

Then we create the system startup links for BIND:

chkconfig --levels 235 named on

We don't start BIND now because it will fail because of a missing /var/named/chroot/etc/named.conf. This will be created later on by ISPConfig (if you use ISPConfig's DNS Manager, that is).

We don't start BIND now because it will fail because of a missing /var/named/chroot/etc/named.conf. This will be created later on by ISPConfig (if you use ISPConfig's DNS Manager, that is).

This is untrue. when ISPConfig is installed the named.conf file is not there, and bind does not start.

 There is also a step left out where you should have typed yum install flex. My installation failed because it was never installed in the perfect setup, even though it is required for ISPConfig.
