6 Quota

To install quota, we run this command:

yum install quota

Edit /etc/fstab and add ,usrquota,grpquota to the / partition (/dev/VolGroup00/LogVol00):

vi /etc/fstab

/dev/VolGroup00/LogVol00 /                       ext3    defaults,usrquota,grpquota        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
tmpfs                   /dev/shm                tmpfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
sysfs                   /sys                    sysfs   defaults        0 0
/dev/VolGroup00/LogVol01 swap                    swap    defaults        0 0

Then run

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

to enable quota.

7 Install A Chrooted DNS Server (BIND9)

To install a chrooted BIND9, we do this:

yum install bind-chroot

If you see this error: Transaction Check Error: file /etc/named.conf from install of bind-9.3.2-12.FC5 conflicts with file from package caching-nameserver-7.3-5.FC5, you can ignore it.

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
chkconfig --levels 235 named on
/etc/init.d/named start

BIND will run in a chroot jail under /var/named/chroot/var/named/. I will use ISPConfig to configure BIND (zones, etc.).

8 MySQL (5.0)

To install MySQL, we do this:

yum install mysql mysql-devel mysql-server

Then we create the system startup links for MySQL (so that MySQL starts automatically whenever the system boots) and start the MySQL server:

chkconfig --levels 235 mysqld on
/etc/init.d/mysqld start

Now check that networking is enabled. Run

netstat -tap

It should show a line like this:

tcp        0      0 *:mysql                     *:*                         LISTEN      2008/mysqld

If it does not, edit /etc/my.cnf and comment out the option skip-networking:

vi /etc/my.cnf

#skip-networking

and restart your MySQL server:

/etc/init.d/mysqld restart

Run

mysqladmin -u root password yourrootsqlpassword
mysqladmin -h server1.example.com -u root password yourrootsqlpassword

to set a password for the user root (otherwise anybody can access your MySQL database!).
