I found an installation guide of VHCS on CentOS 4.x in its wiki. It looks a bit complicate but not too bad for me. So I suggested my friend to give it a try. He installed CentOS 4.4 as usual and then I have to install further packages to meet the requirements of VHCS. This is a long, long story. In fact, VHCS doesn't support CentOS exactly. The only distributions supported by VHCS are just Debian-based and SUSE. That's why I have to make it work myself.

In order to install VHCS on CentOS 4.4, you have to follow above document until you have all requirements installed but VHCS itself and then follow below procedures.

1. Edit Makefile by changing HOST_OS to centos

   HOST_OS=centos
   

2. Edit configs/Makefile to know about centos

   diff -ruN vhcs2-2.4.7.1.orig/configs/Makefile vhcs2-2.4.7.1/configs/Makefile

3. Then copy file from suse to centos as a template.

   cd configs/dists
   cp -Rp suse centos
   

4. Edit Makefile and vhcs2.conf in configs/dists/centos

5. Edit Makefile, httpd.conf, parts/vhcs2_base.tpl and working/vhcs2.conf in configs/dists/centos/apache

6. Edit main.cf in configs/dists/centos/postfix/main.cf to make sure setgid_group is postdrop

   setgid_group = postdrop
   

7. Make sure that all paths in configs are correctly set

8. Edit vhcs2_daemon in configs/dists/centos/init.d as follow.

9. Then run make install and vhcs2-setup as usual

Then you have to restart all services again.

for i in httpd named courier postfix proftpd vhcs2_daemon; do \
    chkconfig $i on; \
    service $i restart; \
done

All done.
