8 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 ,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 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 /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.
9 Install A Chrooted DNS Server (BIND9)
To install a chrooted BIND9, we do this:
yum install bind-chroot
Then do this:
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
cp /usr/share/doc/bind-9.3.6/sample/var/named/named.local /var/named/chroot/var/named/named.local
cp /usr/share/doc/bind-9.3.6/sample/var/named/named.root /var/named/chroot/var/named/named.root
touch /var/named/chroot/etc/named.conf
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.).
10 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 | grep mysql
It should show a line like this:
[root@server1 ~]# netstat -tap | grep mysql
tcp 0 0 *:mysql *:* LISTEN 2420/mysqld
[root@server1 ~]#
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!).
