The Perfect Server - CentOS 6.3 x86_64 (Apache2, Dovecot, ISPConfig 3) - Page 2

Choose your time zone:

Give root a password:

Next we do the partitioning. Select Replace Existing Linux System(s). This will give you a small /boot partition and a large / partition which is fine for our purposes:

Select Write changes to disk:

The hard drive is being formatted:

Now we select the software we want to install. Select Basic Server, then check CentOS in the additional repositories field, choose Customize later and click on Next:

The installation begins. This will take a few minutes:

Finally, the installation is complete, and you can remove your DVD from the computer and reboot it:

After the reboot, log in as root.

I want to install ISPConfig at the end of this tutorial which comes with its own firewall. That's why I disable the default CentOS 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 CentOS firewall).



... and disable the firewall. Hit OK afterwards:

Confirm your choice by selecting Yes:

If you did not configure your network card during the installation, you can do that now. Run...


... and go to Device configuration:

Select your network interface:

Then fill in your network details - disable DHCP and fill in a static IP address, a netmask, your gateway, and one or two nameservers, then hit Ok:

Next select Save:

You can also specify additional nameservers. Select DNS configuration:

Now you can fill in additional nameservers and hit Ok:

Hit Save&Quit afterwards:

You should run


now to check if the installer got your IP address right:

[root@server1 ~]# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:0C:29:00:85:AC
          inet addr:  Bcast:  Mask:

          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

[root@server1 ~]#

Check your /etc/resolv.conf if it lists all nameservers that you've previously configured:

cat /etc/resolv.conf

If nameservers are missing, run


and add the missing nameservers again.

Now, on to the configuration...

Anyone who uses this tutorial should be aware of this bug with the changes ISPConfig3 makes to dovecot on Fedora/CentOS installs:

You'll also need to install php-common

 yum install php-common

EPEL name has been upgraded to:

From: at: 2013-01-20 16:21:31

Yum installed dovecot 2.0.9.el6_1.1

and  dovecot-mysql 2.0.9-2.el6_1.1

 This seems to cause a failure in amavis:

amavis[8819]: (08819-01-10) Blocked MTA-BLOCKED in maillog

I have tried 

mv /etc/dovecot/dovecot.conf /etc/dovecot/

cp /etc/dovecot.conf /etc/dovecot/dovecot.conf


service dovecot restart

service amavisd restart

service postfix restart


# this seems to have worked ok for me - mail now being sent out.

I was having errors in my maillog as follows;

Jan 29 20:18:45 centos postfix/smtpd[25440]: warning: SASL: Connect to private/auth failed: No such file or directory
Jan 29 20:18:45 centos postfix/smtpd[25440]: fatal: no SASL authentication mechanisms

The comment above from DFen;

mv /etc/dovecot/dovecot.conf /etc/dovecot/
cp /etc/dovecot.conf /etc/dovecot/dovecot.conf
This fixed my issues

Thank you for the helpful and well explained tutorial.
For some reason the link to download mod_ruby (wget is not working.

Here is one that works

Thank for walkthrough

I found that on some setups phpmyadmin and squirrelmail can't load. By editing the "squirrelmail.conf" and "phpmyadmin.conf" file in "/etc/httpd/conf" and adding

<Directory "/usr/share/phpmyadmin">

  <IfModule prefork.c>

LoadModule php5_module modules/


<IfModule !prefork.c>

  LoadModule php5_module modules/



# Cause the PHP interpreter to handle files with a .php extension.


<FilesMatch \.php$>

    SetHandler application/x-httpd-php


  Order Allow,Deny

  Allow from all


From: CanaDave at: 2012-07-14 23:37:56 should mention that when you start named:

/etc/init.d/named start takes a few minutes to generate a key...I thought it was crashed so I Ctrl-C'd it a couple of times then eventually I found how to generate the key manually:

]# rndc-confgen -a

]# chmod 666 /etc/rndc.key


]# chkconfig --levels 235 named on
]# /etc/init.d/named start

...I don't know if it would have generated the key on its own, it did say 'Generate Key': but seemed to be waiting for input from me.

Anyway, cool walkthrough...I set it up in a VM in Hyper-V...

Vlogger seems no longer available, is there any alternative or does ispconfig really need this?

From: life_watcher at: 2013-01-10 03:54:29

Great tutorial! Thank you!

a little addition - fail2ban seems to conflict with bastille and disable firewall set by ISPConfig (with uses bastille to manage iptables). As result no active firewall except fail2ban rules... I had to remove fail2ban to make it working...

Thank you! 


From: at: 2013-01-11 12:17:30

i will sugest fail2ban + APF  and just disable the ispconfig firewall ( only if you have CLI access )

From: Anonymous at: 2012-09-22 02:36:42

Thank you !

 Best TUTORIAL I'v found online, up-to-date everything just works, unlike many other - half-finished tutorials!!!!

Thanks for your time.

Simply awesome. Thank you. Only wish I would have come across this information 3 days ago.

It's a good tutorial, but I found 2 things that doesn't seem to be right:

1) During the installation of webalizer and awstats an error occurs "No package awstats available". I have no idea where to get it, I checked the art, dag and epel repositories, but no awstats (anymore) :(

2) On a 64-bits Centos 6.3 OS, when installing mod_python the apache error log shows:

[Sun Oct 21 17:48:08 2012] [error] python_init: Python version mismatch, expected '2.6.5', found '2.6.6'.
[Sun Oct 21 17:48:08 2012] [error] python_init: Python executable found '/usr/bin/python'.
[Sun Oct 21 17:48:08 2012] [error] python_init: Python path being used '/usr/lib64/'.

I heard that it's better to remove mod_python and use mod_wsgi instead. I tried this and the errors are gone. However it does show a warning in the error_log:

[Sun Oct 21 20:00:08 2012] [warn] mod_wsgi: Compiled for Python/2.6.2.
[Sun Oct 21 20:00:08 2012] [warn] mod_wsgi: Runtime using Python/2.6.6.

Maybe you can rewrite the manual for these 2 issues so it will be even better in the (near) future!
