The Perfect Server - OpenSUSE 11 - Page 3

4 Configure the Network settings

We use Yast, the OpenSuSE system management tool to reconfigure the network card settings. After the first boot, the system is configured to get the IP address with DHCP. For a server we will switch it to a static IP address.

Run

yast2

Select "Network Devices > Network Settings":

Select your network card and then Edit:

Select "Statically assigned IP address" and enter the IP address, subnet mask and hostname and save the changes by selecting "Next":

Now select "Hostname/DNS" and enter the hostname and nameservers:

Now select "Routing" and enter the default gateway and click on "Finish":

Now restart the network:

/etc/init.d/network restart

To configure the firewall, select "Security & Users > Firewall" in Yast.

Then add the following services to the list of allowed services:

Select "Advanced" and enter the TCP ports 80, 81 and 443:

And select "Next" to save the changes.

5 Install Some Software

Now we install a few packages that are needed later on. Run

yast2 -i findutils readline libgcc glibc-devel findutils-locate gcc flex lynx compat-readline4 db-devel wget gcc-c++ make vim telnet cron iptables iputils man man-pages

If you're on a 64-bit system (only then!), you must also do this:

cd /usr/lib
ln -s /usr/lib64/libssl.a libssl.a
ln -s /usr/lib64/libssl.so libssl.so

6 Quota

To install quota, run

yast2 -i quota

Edit /etc/fstab to look like this (I added ,usrquota,grpquota to the mountpoints / and /srv):

vi /etc/fstab

/dev/disk/by-id/scsi-SATA_VMware_Virtual_00000000000000000001-part1 swap                 swap       defaults              0 0
/dev/disk/by-id/scsi-SATA_VMware_Virtual_00000000000000000001-part2 /                    ext3       acl,user_xattr,usrquota,grpquota        1 1
/dev/disk/by-id/scsi-SATA_VMware_Virtual_00000000000000000001-part3 /srv                 ext3       acl,user_xattr,usrquota,grpquota        1 2
proc                 /proc                proc       defaults              0 0
sysfs                /sys                 sysfs      noauto                0 0
debugfs              /sys/kernel/debug    debugfs    noauto                0 0
usbfs                /proc/bus/usb        usbfs      noauto                0 0
devpts               /dev/pts             devpts     mode=0620,gid=5       0 0

Then run:

touch /aquota.user /aquota.group
chmod 600 /aquota.*
touch /srv/aquota.user /srv/aquota.group
chmod 600 /srv/aquota.*

mount -o remount /
mount -o remount /srv

quotacheck -avugm
quotaon -avug

Dont be worried if you see these error messages

quotacheck: WARNING - Quotafile //aquota.user was probably truncated. Cannot save quota settings...
quotacheck: WARNING - Quotafile //aquota.group was probably truncated. Cannot save quota settings...
quotacheck: Scanning /dev/sda2 [/] done

7 DNS Server

Run

yast2 -i bind bind-chrootenv bind-devel bind-utils

Then we add the system startup links for BIND and start it:

chkconfig --add named
/etc/init.d/named start

Bind will run in a chroot jail under /var/lib/named.
