The Perfect Server - OpenSUSE 11.2 x86_64 [ISPConfig 2] - 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 (e.g. server1.example.com) and nameservers (e.g. 145.253.2.75 and 213.191.92.86):

Now select Routing and enter the default gateway and hit OK:

To configure the firewall (in case you didn't configure it during the basic installation), select Security and Users > Firewall in Yast:

I want to install ISPConfig at the end of this tutorial which comes with its own firewall. That's why I disable the default OpenSUSE firewall now. Of course, you are free to leave it on and configure it to your needs (but then you shouldn't use any other firewall later on as it will most probably interfere with the OpenSUSE firewall).

Select Disable Firewall Automatic Starting and Stop Firewall Now, then hit Next:

Hit Finish and leave Yast:

 

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

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 Journaled Quota

To install quota, run

yast2 -i quota

Edit /etc/fstab to look like this (I added ,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0 to the mountpoints / and /srv):

vi /etc/fstab

/dev/sda1            swap                 swap       defaults              0 0
/dev/sda2            /                    ext4       acl,user_xattr,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0        1 1
/dev/sda3            /srv                 ext4       acl,user_xattr,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0        1 2
proc                 /proc                proc       defaults              0 0
sysfs                /sys                 sysfs      noauto                0 0
debugfs              /sys/kernel/debug    debugfs    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 - they are normal when you run quotacheck for the first time:

server1:~ # quotacheck -avugm
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
quotacheck: Checked 4670 directories and 51529 files
quotacheck: WARNING - Quotafile /srv/aquota.user was probably truncated. Cannot save quota settings...
quotacheck: WARNING - Quotafile /srv/aquota.group was probably truncated. Cannot save quota settings...
quotacheck: Scanning /dev/sda3 [/srv] done
quotacheck: Checked 6 directories and 2 files
server1:~ #

 

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.

Hey Falko,

I read this at opensuse.org today.

Starting with openSUSE 11.2, a live upgrade from the prior version of openSUSE 11.1 is officially supported. This allows one to perform a complete operating system update in place, without reloading everything from scratch. For versions prior to 11.2 see Upgrade/Unsupported.

Does this mean that your future how-to's for Opensuse Perfect Server will demonstrate the upgrade path?  Thanks.

Dave

Before using:

 server1 # mysql_secure_installation

Please go to root and then make secure installation of mySQL or in openSUSE will give an error:

 server1 # cd / server1
 server1 # mysql_secure_installation
