Compiling ipvsadm on different Linux distributions

2012-03-17T09:11:52Z

Zzg: /* Cannot find kernel source directory */

== Introduction ==

Since [[IPVS]] interface to user-space is different in different Linux kernel versions, there are different versions of [[ipvsadm]] for IPVS inside the different Linux kernel versions.

For IPVS inside the Linux kernel 2.6, you need to use [[ipvsadm]] version 1.24 or later.

For IPVS inside the Linux kernel 2.4, you need to use [[ipvsadm]] 1.21 series.

For IPVS patch for the Linux kernel 2.2, you need to use [[ipvsadm]] version 1.15.

== Red Hat Enterprise Linux 3 ==

Red Hat Enterprise Linux 3 (or CentOS 3) kernel has already included the [[IPVS]] patch, so that we do not need to build the kernel image with IPVS support ourselves.
[root@penguin root]# modprobe ip_vs
[root@penguin root]# cat /proc/net/ip_vs
IP Virtual Server version 1.0.8 (size=65536)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn

For the IPVS version 1.0.8, we should use the ipvsadm version 1.21-10, which support the Linux kernel 1.0.4 or later.

On Red Hat Enterprise Linux 3, make sure that kernel-source rpm is installed at system.
[root@penguin src]# rpm -q kernel-source
kernel-source-2.4.21-47.0.1.EL
[root@penguin src]# pwd
/usr/src
[root@penguin src]# ln -s linux-2.4.21-47.0.1.EL linux

Then, we can build the ipvsadm-1.21-10 rpm in the following command:
rpmbuild --rebuild ipvsadm-1.21-10.src.rpm

Note that ipvsadm-1.21-11.src.rpm is for IPVS 1.0.12 or later, IPVS 1.0.12 is in the Linux kernel 2.4.28 or later 2.4.xx versions.

== Red Hat Enterprise Linux 4 ==

On Red Hat Enterprise Linux 4, make sure that kernel-source rpm is installed at system (as showed at http://kbase.redhat.com/faq/FAQ_85_5109.shtm).

<pre>
# up2date redhat-rpm-config rpm-build kernel-utils

# up2date --get-source kernel

# rpm -ivh /var/spool/up2date/kernel*.src.rpm

# cd /usr/src/redhat/SPECS

# rpmbuild -bp --target=i686 kernel-2.6.spec

# cp -a /usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9 /usr/src

# ln -s /usr/src/linux-2.6.9 /usr/src/linux
</pre>

Then, we can build the ipvsadm-1.24 rpm in the following command:
rpmbuild --rebuild ipvsadm-1.24-6.src.rpm

And install using:
rpm -ivh /usr/src/redhat/RPMS/i386/ipvsadm-1.24-6.i386.rpm
