The Perfect Server - CentOS 5.5 x86_64 [ISPConfig 3] - Page 3

4 Adjust /etc/hosts

Next we edit /etc/hosts. Make it look like this:

vi /etc/hosts

# Do not remove the following line, or various programs
# that require network functionality will fail.               localhost.localdomain localhost  server1
::1             localhost6.localdomain6 localhost6


5 Configure Additional IP Addresses

(This section is totally optional. It just shows how to add additional IP addresses to your network interface eth0 if you need more than one IP address. If you're fine with one IP address, you can skip this section.)

Let's assume our network interface is eth0. Then there is a file /etc/sysconfig/network-scripts/ifcfg-eth0 which contains the settings for eth0. We can use this as a sample for our new virtual network interface eth0:0:

cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0:0

Now we want to use the IP address on the virtual interface eth0:0. Therefore we open the file /etc/sysconfig/network-scripts/ifcfg-eth0:0 and modify it as follows (we can leave out the HWADDR line as it is the same physical network card):

vi /etc/sysconfig/network-scripts/ifcfg-eth0:0

# Intel Corporation 82545EM Gigabit Ethernet Controller (Copper)

Afterwards we have to restart the network:

/etc/init.d/network restart

You might also want to adjust /etc/hosts after you have added new IP addresses, although this is not necessary.

Now run


You should now see your new IP address in the output:

[root@server1 ~]# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:0C:29:FD:78:BE

6 Disable The Firewall And SELinux

(You can skip this chapter if you have already disabled the firewall and SELinux at the end of the basic system installation (in the Setup Agent).)

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).

SELinux is a security extension of CentOS that should provide extended security. In my opinion you don't need it to configure a secure system, and it usually causes more problems than advantages (think of it after you have done a week of trouble-shooting because some service wasn't working as expected, and then you find out that everything was ok, only SELinux was causing the problem). Therefore I disable it, too (this is a must if you want to install ISPConfig later on).



Set both Security Level and SELinux to Disabled and hit OK:

Afterwards we must reboot the system:



7 Install Some Software

First we import the GPG keys for software packages:

rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*

Enable the contrib and centosplus repositories:

vi /etc/yum.repos.d/CentOS-Base.repo

Edit the lines below:


Then we update our existing packages on the system:

yum update

Now we install some software packages that are needed later on:

yum groupinstall 'Development Tools'

yum groupinstall 'Development Libraries'


8 Quota

(If you have chosen a different partitioning scheme than I did, you must adjust this chapter so that quota applies to the partitions where you need it.)

To install quota, we run this command:

yum install quota

Edit /etc/fstab and add ,usrquota,grpquota to the / partition (/dev/VolGroup00/LogVol00):

vi /etc/fstab

/dev/VolGroup00/LogVol00 /                       ext3    defaults,usrquota,grpquota        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
/dev/VolGroup00/LogVol01 swap                    swap    defaults        0 0

Then run

touch /aquota.user /
chmod 600 /aquota.*
mount -o remount /
quotacheck -avugm
quotaon -avug

to enable quota.


9 Install Apache, MySQL, phpMyAdmin

First we enable the RPMforge repository on our CentOS system as lots of the packages that we are going to install in the course of this tutorial are not available in the official CentOS 5.5 repositories:

rpm --import

cd /tmp
rpm -ivh rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm

(If the above link doesn't work anymore, you can find the current version of rpmforge-release here:

Afterwards we can install the needed packages with one single command:

yum install ntp httpd mysql-server php php-mysql php-mbstring php-mcrypt phpmyadmin

I've been messing with clearOS but they are using old versions(like php 5.1.9) of everything it was just not worth that hassle for a all in one control panel.  I've never used ISPconfig but it looks nice.

Why is it that there is no some more up-to-date postfix with mysql form centos?

I know that centos provide what red hat does, but is it that hard to compile postfix with mysql on centos? I do not know how to do this, but I would use this system for sure if postfix would be updated to newer one.

IMO dovecot and sieve are great change for better in ISPconfig. With amavis, SA and clam, latest postfix would round up an excelent email server part of it.

From: Tim at: 2010-06-27 09:54:47

That's exactly what I was looking to do. I built Postfix v2.6.5 and Dovecot  v1.2 all from source with the sieve plugin also from source. The key is to build Postfix with mysql support. Download the source for Postfix, extract the package and run this from the source directory for Postfix:


Be sure you have installed the dev package for mysql ( mysql-devel )  and added a postfix and postdrop user and group ( read the INSTALL file in the source dir )

 make makefiles CCARGS='-DUSE_SASL_AUTH -DDEF_SERVER_SASL_TYPE=\"dovecot\" -DUSE_TLS -DHAS_MYSQL -I/usr/include/mysql' \
 AUXLIBS="-lssl -lcrypto  -L/usr/lib/mysql -lmysqlclient -lz -lm -lsasl2"

make install

then follow the rest of the ispconfig 3 How-To

From: at: 2010-07-13 00:03:24

Dovecot version in step 10 is out of date.  I had to use the following while doing the install today.

rpm -ivh
rpm -ivh

 I hope this does not affect later parts of this setup.

From: at: 2010-08-09 10:54:36

Again out? Anyone has updated links?

From: Ken at: 2010-08-11 23:18:37

Instructing readers to download and install RPM files manually from a repo such as or even RPMFORGE is irresponsible.  Instead, teach them the correct way to use a repo.  Download the release/repo RPM then use "yum".  In the case of ATRPMS and CentOS5, download atrpms-repo from  Edit


and add the line (in this instance) to limit ATRPMS packages only to dovecot.  Otherwise you may make your system unstable.

includepkgs=dovecot dovecot-sieve

Then run "yum install dovecot dovecot-sieve" and you're done.

This also eliminates the need to manually download newer versions of dovecot.  Just run "yum update" and they get updated with the rest of the RHEL/CentOS packages.

From: Anonymous at: 2010-09-23 19:04:26

Thank you for that info.

From: Adam at: 2010-10-01 15:31:31

Don't use this method! You will end up with dovecot 2.0 which doesn't work with ISPConfig.

From: Anonymous at: 2010-10-08 12:01:26

you will NOT!!

as far as you add in addition:


btw. I used the testrepo not the default one



From: Mike at: 2010-10-20 19:51:55

For those who are copy/pasting, install using

yum install dovecot dovecot-sieve

by using the following in your /etc/yum.repos.d/atrpms.repo.  As of the date of this comment, dovecot is not listed in stable, it is listed in testing.

name=Red Hat Enterprise Linux 5 - x86_64 - ATrpms
includepkgs=dovecot dovecot-sieve

# requires stable
name=Red Hat Enterprise Linux 5 - x86_64 - ATrpms testing
includepkgs=dovecot dovecot-sieve

# requires stable and testing
name=Red Hat Enterprise Linux 5 - x86_64 - ATrpms bleeding

From: Ash at: 2010-12-01 22:51:37

The following worked for me...


name=Red Hat Enterprise Linux 5 - i386 - ATrpms
includepkgs=dovecot dovecot-sieve

# requires stable
name=Red Hat Enterprise Linux 5 - i386 - ATrpms testing
includepkgs=dovecot dovecot-sieve

# requires stable and testing
name=Red Hat Enterprise Linux 5 - i386 - ATrpms bleeding
"/etc/yum.repos.d/atrpms.repo" 26L, 620C

From: bkraul at: 2010-12-29 18:56:55

This method installs dovecot 1.0. Then dovecot-sieve failse because it has dovecot 1.2 as a dependency. Am I missing something here?

From: at: 2010-08-09 10:58:42

okay, for step 10, these are updated links:

Step 14

sa-update results in this:

so SpamAssassin is not able to update?

Any fixes?

From: at: 2010-11-10 13:16:17

If dovecot fails to start saying " Fatal: listen(::, 143) failed: Address already in use" then add "listen=*" to your /etc/dovecot.conf file. It's trying to listen for ipv6 addresses which are not enabled by default (on our standard images anyway).

While according to PMA themselves ( using cookie vs. http authentication results in about the same security, I prefer using cookie as the login is much nicer.

To enable, generate a blowfish secret (using something like is helpful) and paste it into the line  $cfg['blowfish_secret'] = '' in /usr/share/phpmyadmin/

Additionally, while it is mostly "security by obscurity" (and some pretty bad obscurity at that), I prefer to change the default /phpmyadmin alias to /pma, which can be done by changing the appropriate "alias" line in /etc/httpd/conf.d/phpmyadmin.conf. I also deleted the other two aliases (/phpMyAdmin and /mysqladmin).

From: Joseph Mouhanna at: 2010-11-08 01:29:53

Note that clamd is obsoleted by clamav, so replace instances of clamd with clamav.

From: Joseph Mouhanna at: 2010-11-09 11:57:43

In addition to these instructions, you need to install the GPG public key, prior to running yum, else it will fail with a message about the missing key:

rpm --import RPM-GPG-KEY.atrpms

From: Anonymous at: 2010-12-13 18:01:33

On my installation I had to correct as follow:

ln -s /var/run/clamav/clamd.sock /var/spool/amavisd/clamd.sock

If sendmail is not already in use then you do not need to use the stop command. You can also save the trouble of setting permissions and changing settings for sendmail by simply deleting it with the following command which will remove the application and all dependancies

rpm –e --nodeps sendmail

From: csf at: 2011-02-03 13:59:27

After completing tutorial several times with i386 and _64 OS on several servers to be sure. Dovecot and dovecot-sieve installs, starts but does not Send  Receive email. I have tried both dovecot 1x and 2x packages.

Everything looks fine in ISPConfig monitor. ALL services running.

Also, ISPConfig by default sends an email to client when client creates account. On my systems client doesnt receive email from ISPConfig.My clients are able to log into squirrelmail, but not send/receive emails.

From: Anonymous at: 2011-04-30 10:49:26

For Centos the installer seems to have been updated to put the amavisd.conf file in /etc/amavisd.conf (and not /etc/amavisd/amavisd.conf which I think is the debian place for it). This means that you don't need to change /etc/sysconfig/amavisd (the default conf location is /etc/amavisd.conf)

 I hope that save someone else some time and confusion.

you probably also need to "yum -y install gcc-c++".Had to install this on my centos 5 server to be able to get around this.

From: Mark Pugh at: 2010-09-17 15:54:47

I had this problem. It's actually because on my RHEL base install the /tmp mount has noexec as an option in /etc/fstab:

 LABEL=/tmp              /tmp                    ext3    defaults,nosuid,nodev,noexec        1 2

If you copy your suphp dir to your home directory and then try it, it's fine:

 mv suphp-0.7.1 ~
cd ~/suphp-0.7.1


From: at: 2010-06-02 23:49:14

The error I encountered was due to the directory tmp.

I am on a remote hosted server and the tmp directory is mounted with noexec

So, I changed to /usr/local/src and all is well.

From: newbie at: 2010-06-28 05:46:15

in line :

Then we add the suPHP module to our Apache configuration...

Is this right? I think maybe it should be:

vi /etc/httpd/conf/httpd.conf

Sorry if I'm mistaken

From: at: 2010-07-06 23:02:56

The Apache config file ('/etc/httpd/conf/httpd.conf') file actually loads any '.conf' file found in '/etc/httpd/conf.d/' so, though the HOWTO is actually correct, it may have been better worded to;

Then we add the suPHP module to our Apache configuration by creating a new file 'suphp.conf' in '/etc/https/conf.d/'...

Once the linked file is created:  /etc/named.conf  (has a green link arrow on it)  adjust the permissions for the group "named" to read & write then restart the named service.

I ran this below in addition to the step 17 commands and finally saw the named.conf link file... Once the permissions were adjusted the service starts fine.

ln -s /chroot/named/etc/named.conf /etc/named.conf

hope that helps

Hi there.

I followed this tutorial all the way through however even after setting up a client, site, email domain and mailbox in ISPconfig - I cannot login to Squirrelmail - Just keeps on saying:

Unknown user or password incorrect.

Very frustrating!

From: rwheindl at: 2010-11-22 23:36:46

I spent a few days trying to get DNS to resolve using "dig @localhost" and found an error in the last line of /var/named/chroot/etc/named.conf.

ISPConfig 3 defaults to: /var/named/chroot/var/named/named.local
This setting is found under: SYSTEM -> Server Config -> DNS

However, the instructions for named.conf file sets it to:
include "/var/named/chroot/etc/named.conf.local";

Had to change it to reflect the setting in ISPConfig to get bind to resolve names properly:
include "/var/named/chroot/var/named/named.local";

 Then run "/etc/init.d/named restart" with the corrected setting.

From: steve at: 2010-12-08 13:22:00

after the successfull installation of ISPConfig 3 the monitoring interface told me that fail2ban is not installed. After checking I found that it is installed and running. Finally i added a symink for fail2ban. This worked fine.

So if anyone has issues showing fail2ban in the monitoring gui just add a symlink like this:

ln -s /usr/share/fail2ban/ /usr/bin/fail2ban

Thanks to the ISPConfig Team your software really ROCK!!!!!!

Thank you! I was following "The Perfect Server - CentOS 5.6 x86_64 [ISPConfig 3]" guide and ran into problems in the pure-ftpd section. This fixed my issue. I have VPS hosting from VolumeDrive.

don't just copy and paste those informations, take a look on this when you copy and paste

Does this tutorial (The Perfect Server - CentOS 5.5 x86_64 [ISPConfig 3]) work for the 32bit version of CentOS

From: Krissie at: 2010-06-25 05:50:18

It appears to work - just replace all instances of x86_64 in the various urls and filenames to i386

From: bkraul at: 2010-08-03 06:01:16

Also make sure that on step 10 - Dovecot, you do not do the following step:

rm -fr /usr/lib/dovecot/
ln -s /usr/lib64/dovecot/ /usr/lib/dovecot

From: MS at: 2010-11-09 12:15:53

On i386 system step 10 is :
ln -sf /usr/lib/dovecot

 MS :)

How about doing this?

 ln -s /var/named/chroot/etc/named.conf* /etc/


From: Arno at: 2011-02-16 16:40:18

same same..

I followed the howto line by line, but bind does not record the domains. they are mentioned in ispconfig, but the zone is empty.

after ln -s or cp of the /etc/named.conf.local to /var/named/chroot/etc/

 then bind see all, but does not start because a lack of ttl.

after removing this file/link all works, but no local domainlookup..and no zones (except rootzone)

If jou are installing ISPconfig on a VM which is running on Hyper-V you might run into problems with the firewall which is used by ISPconfig.

This is the case when you install the Linux Integration components available from Microsoft. The problem is that the synthetic network adapters installed by the integration components do not get an interface name beginning with 'eth'.

-> The Bastille firewall script explicitly calls for 'eth+' interfaces.

You have to edit /etc/Bastille/bastille-firewall.cfg.

-> PUBLIC_IFCES="eth+ ppp+ slip+ venet+"

should be changed into

-> PUBLIC_IFCES="seth+ ppp+ slip+ venet+"

update to step 23

cd /tmp
tar xvfz ISPConfig-
cd ispconfig3_install/install/

very good manual. many thanks all

From: whopsii at: 2010-09-17 12:01:49

i followed all the step ultra carefully since i am a novice.

it was a hilarious moment when i saw my server working just like the last page shown.

then i use command  " shutdown -r now " to restart my server.

then problem starting to exist. i cant open my server web page and after doing some research, i found this problem

 "  Starting httpd: Warning: DocumentRoot [/var/www/clients/client1/web2/web] does not exist
httpd: bad user name web2 "

and something message like "failed" and then i found out that i cant start my httpd.

any clue from the expert around here.


From: Skyler Sully at: 2010-10-09 15:17:35

Hey whopsii,

 You probably figured this out--but you need to configure apache (httpd) to:

  • Run on boot (use /sbin/service --levels 235 httpd on)
  • Accessible through firewall (type in 'setup' command and go to firewall configuration)

When you restarted your computer, you stopped the service, but since it wasn't configured to come back up--there you go.

 If that doesn't work, it could be something else, but that's where I would start.

Hello, and thank you for this great tutorial.

It works perfect, from page 1 to the last. It's really the perfect server :).

I was thinking about a solution, regarding the 25 port, that is blocking by ISP's  i found'it but i don't now how to set up. Maybe you can help me please.

Now, i host different domains on isp server, all o them with email service. The email service works on 25 port. If a client connect with Outlook to chek his emails but his ISP blocks the 25 port, i want him to have an alternative. Also if it connect with a modem, that by default the modem ip, is see like makeing spam, i  want a solution that if he change de smtp port from 25 to another, the emails will not be checked for spam, and the spamhaus message will not be seen by the client.

I think about a solution, maybe you have de programing codes to makeit work, or maybe already exist a topic to resolve this. I din'd found it.

So...let's setup in the email client, for example Outlook, the SMTP port from 25, to lets say, 35000, so that all connections are made on this port.

Now in the server, we setup a port, the same port, 35000, to listen all the traffic that comes. And if finds a email traffic relative to a domain that it hosts, take that email and deliver without cheking for spam. This is a solution for the clients that connect with a modem, 3g or adsl, or for the clients that connects from an ISP that block 25 port.

I use centos 5.5 x86_64 and isp config 3. 

Can you help me wiht this, i must say im novice at this chapter but i learn very fast.


Thank you!

Unbelievable! Level 1 VPS Hostgator users need to follow this. I was at a loss initially and this helped me get started at last!

Thank you again for the time you took to save me from jumping off my balcony.
