The Perfect Server - CentOS 5.4 With ISPConfig 3

2010

[THE PERFECT SERVER ‐ CENTOS 5.4 X86_64 WITH ISPCONFIG 3] This tutorial shows how to prepare a CentOS 5.4 x86_64 server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more.Please note that this setup does not work for ISPConfig 2! It is valid for ISPConfig 3 only!I do not issue any guarantee that this will work for you!

1 Requirements

To install such a system you will need the following:

Download the CentOS 5.4 DVD or the seven CentOS 5.4 CDs from a mirror next to you (the list of

mirrors can be found here: http://isoredirect.centos.org/centos/5/isos/x86_64/).

a fast internet connection.

2 Preliminary Note

In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100 and the

gateway 192.168.0.1. These settings might differ for you, so you have to replace them where appropriate.

3 Install The Base System

Boot from your first CentOS 5.2 CD (CD 1) or the CentOS 5.2 DVD. Press <ENTER> at the boot prompt

It can take a long time to test the installation media so we skip this test here

The welcome screen of the CentOS installer appears. Click on Next

Choose your language next

Select your keyboard layout

I'm installing CentOS 5.2 on a fresh system, so I answer Yes to the question Would you like to initialize

this drive, erasing ALL DATA?

Now we must select a partitioning scheme for our installation. For simplicity's sake I select Remove

linux partitions on selected drives and create default layout. This will result in a small /boot and a

large / partition as well as a swap partition. Of course, you're free to partition your hard drive however

you like it. Then I hit Next

Answer the following question (Are you sure you want to do this?) with Yes

On to the network settings. The default setting here is to configure the network interfaces with DHCP,

but we are installing a server, so static IP addresses are not a bad idea... Click on the Edit button at the

top right

In the window that pops up uncheck Use dynamic IP configuration (DHCP) and Enable IPv6

support and give your network card a static IP address (in this tutorial I'm using the IP

address 192.168.0.100 for demonstration purposes) and a suitable netmask (e.g. 255.255.255.0)

Set the hostname manually, e.g. server1.example.com, and enter a gateway (e.g. 192.168.0.1) and up

to two DNS servers (e.g. 213.191.92.86 and 145.253.2.75)

Choose your time zone

Give root a password


6

Now we select the software we want to install. Select nothing but Server (uncheck everything else).

Also don't check Packages from CentOS Extras. Then check Customize now, and click on Next

Now we must select the package groups we want to install. Select Editors, Text‐based

Internet, Development Libraries, Development Tools, DNS Name Server, FTP Server, Mail

Server, MySQL Database, Server Configuration Tools, Web Server, Administration

Tools, Base, and System Tools (unselect all other package groups) and click on Next

The installer checks the dependencies of the selected packages

Click on Next to start the installation

The hard drive is being formatted

The installation begins. This will take a few minutes

Finally, the installation is complete, and you can remove your CD or DVD from the computer and

reboot it

After the reboot, select Firewall configuration and hit Run Tool

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). Hit OK afterwards

Then leave the Setup Agent by selecting Exit

Then log in as root and reboot the system so that your changes can be applied:

4 Adjust /etc/hosts

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

reboot

vi /etc/hosts


7

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:

Now we want to use the IP address 192.168.0.101 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):

Afterwards we have to restart the network:

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

necessary.

Now run

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost

192.168.0.100 server1.example.com server1

::1 localhost6.localdomain6 localhost6

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

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

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]

DEVICE=eth0:0

BOOTPROTO=static

BROADCAST=192.168.0.255

IPADDR=192.168.0.101

NETMASK=255.255.255.0

NETWORK=192.168.0.0

ONBOOT=yes

/etc/init.d/network restart


8

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

[root@server1 ~]# ifconfig

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).)

ifconfig


9

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).

Run

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:

Then we update our existing packages on the system:

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

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:

system‐config‐securitylevel

reboot

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

yum update

yum groupinstall 'Development Tools'

yum groupinstall 'Development Libraries'


10

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

Then run

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 5.4 repositories:

(If the above link doesn't work anymore, you can find the current version of rpmforge‐

release here: http://dag.wieers.com/rpm/packages/rpmforge‐release/)

Afterwards we can install the needed packages with one single command (including the packages we need to

build Courier‐IMAP):

yum install quota

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

touch /aquota.user /aquota.group

chmod 600 /aquota.*

mount ‐o remount /

quotacheck ‐avugm

quotaon ‐avug

rpm ‐‐import http://dag.wieers.com/rpm/packages/RPM‐GPG‐KEY.dag.txt

cd /tmp

wget http://dag.wieers.com/rpm/packages/rpmforge‐release/rpmforge‐release‐0.3.6‐1.el5.rf.x86_64.rpm

rpm ‐ivh rpmforge‐release‐0.3.6‐1.el5.rf.x86_64.rpm


11

10 Install Courier‐IMAP, Courier‐Authlib, And Maildrop

Unfortunately there are no rpm packages for Courier‐IMAP, Courier‐Authlib, and Maildrop, therefore we have

to build them ourselves.

RPM packages should not be built as root; courier‐imap will even refuse to compile if it detects that the

compilation is run as the root user. Therefore we create a normal user account now (compileuser in this

example) and give him a password:

We will need the sudo command later on so that the user compileuser can compile and install the rpm

packages. But first, we must allow compileuser to run all commands using sudo:

Run

In the file that opens there's a line root ALL=(ALL) ALL. Add a similar line for compileuser just below that line:

Now we are ready to build our rpm package. First become the user compileuser:

Next we create our build environment:

yum install ntp httpd mysql‐server php php‐mysql php‐mbstring php‐mcrypt phpmyadmin rpm‐build gcc mysql‐devel

openssl‐devel cyrus‐sasl‐devel pkgconfig zlib‐devel pcre‐devel openldap‐devel postgresql‐devel expect libtool‐ltdl‐

devel openldap‐servers libtool gdbm‐devel pam‐devel gamin‐devel

useradd ‐m ‐s /bin/bash compileuser

passwd compileuser

visudo

[...]

root ALL=(ALL) ALL

compileuser ALL=(ALL) ALL

[...]

su compileuser


12

Now we download the source files from http://www.courier‐mta.org/download.php:

Now (still in /tmp) we can build courier‐authlib:

After the build process, the rpm packages can be found

in $HOME/rpm/RPMS/x86_64 ($HOME/rpm/RPMS/i386 if you are on an i386 system):

The command

shows you the available rpm packages:

[compileuser@server1 x86_64]$

Select the ones you want to install, and install them like this:

Now we go back to the /tmp directory and run rpmbuild again, this time without sudo, otherwise the

compilation will fail because it was run as root:



The command

‐rw‐r‐‐r‐‐ 1 compileuser compileuser 941203 Oct 28 15:49 courier‐imap‐debuginfo‐4.7.0‐1.x86_64.rpm


You can install courier‐imap like this:

Now we go back to the /tmp directory and run rpmbuild again, this time to build a maildrop package:



The command

‐rw‐r‐‐r‐‐ 1 root root 63936 Oct 28 15:55 maildrop‐man‐2.4.3‐1.x86_64.rpm


You can now install maildrop like this:

After you have compiled and installed all needed packages, you can become root again by typing

11 Apply Quota Patch To Postfix

We have to get the Postfix source rpm, patch it with the quota patch, build a new Postfix rpm package and

install it.

The last command will show some warnings that you can ignore:

warning: user mockbuild does not exist ‐ using root

warning: group mockbuild does not exist ‐ using root

Now we must edit the file postfix.spec:

exit

sudo rpm ‐ivh maildrop‐2.4.3‐1.x86_64.rpm

cd /usr/src

wget http://ftp‐stud.fht‐esslingen.de/pub/Mirrors/centos/5.4/os/SRPMS/postfix‐2.3.3‐2.1.el5_2.src.rpm

rpm ‐ivh postfix‐2.3.3‐2.1.el5_2.src.rpm

cd /usr/src/redhat/SOURCES

wget http://vda.sourceforge.net/VDA/postfix‐2.3.3‐vda.patch.gz

gunzip postfix‐2.3.3‐vda.patch.gz

cd /usr/src/redhat/SPECS/

vi postfix.spec


16

Then we build our new Postfix rpm package with quota and MySQL support:

Our Postfix rpm package is created in /usr/src/redhat/RPMS/x86_64 (/usr/src/redhat/RPMS/i386 if you are on

an i386 system), so we go there:

The command

[...]

%define MYSQL 1

[root@server1 x86_64]#

Pick the Postfix package and install it like this:

Then turn off Sendmail and start Postfix, saslauthd, and courier‐authlib:

12 Configure Courier

Now we create the system startup links for courier‐imap:

When courier‐imap is started for the first time, it automatically creates the certificate files /usr/lib/courier‐

imap/share/imapd.pem and /usr/lib/courier‐imap/share/pop3d.pem from the /usr/lib/courier‐

imap/etc/imapd.cnf and /usr/lib/courier‐imap/etc/pop3d.cnf files. Because the .cnf files contain the

rpm ‐ivh postfix‐2.3.3‐2.1.x86_64.rpm

chkconfig ‐‐levels 235 courier‐authlib on

/etc/init.d/courier‐authlib start

chkconfig ‐‐levels 235 sendmail off

chkconfig ‐‐levels 235 postfix on

chkconfig ‐‐levels 235 saslauthd on

/etc/init.d/sendmail stop

/etc/init.d/postfix start

/etc/init.d/saslauthd start

chkconfig ‐‐levels 235 courier‐imap on

/etc/init.d/courier‐authlib restart

/etc/init.d/courier‐imap restart


18

line CN=localhost, but our server is named server1.example.com, the certificates might cause problems when

you use TLS connections. To solve this, we delete both certificates...

... and replace the CN=localhost lines in /usr/lib/courier‐imap/etc/imapd.cnf and /usr/lib/courier‐

imap/etc/pop3d.cnf with CN=server1.example.com:

Then we recreate both certificates...

... and restart courier‐authlib and courier‐imap:

13 Install Getmail

Getmail can be installed as follows:

cd /usr/lib/courier‐imap/share/

rm ‐f imapd.pem

rm ‐f pop3d.pem

vi /usr/lib/courier‐imap/etc/imapd.cnf

[...]

CN=server1.example.com

[...]

vi /usr/lib/courier‐imap/etc/pop3d.cnf

[...]

CN=server1.example.com

[...]

./mkimapdcert

./mkpop3dcert

/etc/init.d/courier‐authlib restart

/etc/init.d/courier‐imap restart


19

14 Set MySQL Passwords And Configure phpMyAdmin

Start MySQL:

Then set passwords for the MySQL root account:

Now we configure phpMyAdmin. We change the Apache configuration so that phpMyAdmin allows

connections not just from localhost (by commenting out the <Directory "/usr/share/phpmyadmin"> stanza):

Next we change the authentication in phpMyAdmin from cookie to http:

yum install getmail

chkconfig ‐‐levels 235 mysqld on

/etc/init.d/mysqld start

mysqladmin ‐u root password yourrootsqlpassword

mysqladmin ‐h server1.example.com ‐u root password yourrootsqlpassword

vi /etc/httpd/conf.d/phpmyadmin.conf

#

# Web application to manage MySQL

#

#<Directory "/usr/share/phpmyadmin">

# Order Deny,Allow

# Deny from all

# Allow from 127.0.0.1

#</Directory>

Alias /phpmyadmin /usr/share/phpmyadmin

Alias /phpMyAdmin /usr/share/phpmyadmin

Alias /mysqladmin /usr/share/phpmyadmin

vi /usr/share/phpmyadmin/config.inc.php


20

Then we create the system startup links for Apache and start it:

Now you can direct your browser

to http://server1.example.com/phpmyadmin/ or http://192.168.0.100/phpmyadmin/ and log in with the user

name root and your new root MySQL password.

15 Install Amavisd‐new, SpamAssassin And ClamAV

To install amavisd‐new, spamassassin and clamav, run the following command:

Then we start freshclam, amavisd, and clamd...

... and create some necessary directories:

16 Installing Apache2 With mod_php, mod_fcgi/PHP5, And suPHP

ISPConfig 3 allows you to use mod_php, mod_fcgi/PHP5, cgi/PHP5, and suPHP on a per website basis.

mod_fcgid is not available in the official CentOS repositories, but there's a package for CentOS 5.x in

the centos.karan.org testing repository. We enable the repository as follows:

[...]

/* Authentication type */

$cfg['Servers'][$i]['auth_type'] = 'http';

[...]

chkconfig ‐‐levels 235 httpd on

/etc/init.d/httpd start

yum install amavisd‐new spamassassin clamav clamd unzip bzip2 unrar perl‐DBD‐mysql

chkconfig ‐‐levels 235 amavisd on

chkconfig ‐‐levels 235 clamd on

/usr/bin/freshclam

/etc/init.d/amavisd start

/etc/init.d/clamd start

mkdir /var/run/amavisd /var/spool/amavisd /var/spool/amavisd/tmp /var/spool/amavisd/db

chown amavis /var/run/amavisd /var/spool/amavisd /var/spool/amavisd/tmp /var/spool/amavisd/db


21

Next we open /etc/yum.repos.d/kbsingh‐CentOS‐Extras.repo...

... and set gpgcheck to 0 and enabled to 1 in the [kbs‐CentOS‐Testing] section:

Afterwards we can install Apache2with mod_php5, mod_fcgid, and PHP5:

Next we open /etc/php.ini...

... and change the error reporting (so that notices aren't shown any longer) and add cgi.fix_pathinfo = 1 at the

end of the file:

Next we install suPHP:

cd /etc/yum.repos.d/

wget http://centos.karan.org/kbsingh‐CentOS‐Extras.repo

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

... and create the file /etc/suphp.conf as follows:

cd /tmp

wget http://suphp.org/download/suphp‐0.7.1.tar.gz

tar xvfz suphp‐0.7.1.tar.gz

cd suphp‐0.7.1/

./configure ‐‐prefix=/usr ‐‐sysconfdir=/etc ‐‐with‐apr=/usr/bin/apr‐1‐config ‐‐with‐apxs=/usr/sbin/apxs ‐‐

make

make install

vi /etc/httpd/conf.d/suphp.conf

;chroot=/mychroot

; Security options

allow_file_group_writeable=true

allow_file_others_writeable=false


23

Finally we restart Apache:

17 Install PureFTPd

PureFTPd can be installed with the following command:

Then create the system startup links and start PureFTPd:

allow_directory_group_writeable=true

allow_directory_others_writeable=false

;Check wheter script is within DOCUMENT_ROOT

check_vhost_docroot=true

;Send minor error messages to browser

x‐suphp‐cgi="execute:!self"

/etc/init.d/httpd restart

yum install pure‐ftpd

chkconfig ‐‐levels 235 pure‐ftpd on

/etc/init.d/pure‐ftpd start


24

18 Install MyDNS

There's no MyDNS rpm package for the x86_64 architecture, and building MyDNS from the sources on CentOS

5.4 x86_64 fails because of some incompatibilities with the mysql‐devel package. Therefore we install the

MyDNS rpm package for i386 which works on x86_64 as well:

When the system boots, MyDNS must be started after MySQL. The MySQL startup link has the priority 64 on

CentOS, so the MyDNS startup link must have a priority between 65 and 99. Therefore we open the MyDNS

init script...

... and change

to

Then we create the startup links:

We don't start MyDNS now because it must be configured first ‐ this will be done automatically by the

ISPConfig 3 installer later on.

19 Install Vlogger And Webalizer

Vlogger and webalizer can be installed as follows:

wget http://mydns.bboy.net/download/mydns‐mysql‐1.1.0‐1.i386.rpm

rpm ‐ivh mydns‐mysql‐1.1.0‐1.i386.rpm

vi /etc/init.d/mydns

[...]

# chkconfig: 345 52 50

[...]

[...]

# chkconfig: 345 65 50

[...]

chkconfig ‐‐levels 235 mydns on

yum install webalizer perl‐DateTime‐Format‐HTTP perl‐DateTime‐Format‐Builder


25

20 Install Jailkit

Jailkit is needed only if you want to chroot SSH users. It can be installed as follows (important: Jailkit must be

installed before ISPConfig ‐ it cannot be installed afterwards!):

21 Install fail2ban

This is optional but recommended, because the ISPConfig monitor tries to show the log:

22 Install rkhunter

rkhunter can be installed as follows:

cd /tmp

wget http://n0rp.chemlab.org/vlogger/vlogger‐1.3.tar.gz

tar xvfz vlogger‐1.3.tar.gz

mv vlogger‐1.3/vlogger /usr/sbin/

rm ‐rf vlogger*

cd /tmp

wget http://olivier.sessink.nl/jailkit/jailkit‐2.11.tar.gz

tar xvfz jailkit‐2.11.tar.gz

cd jailkit‐2.11

./configure

make

make install

rm ‐rf jailkit‐2.11*

yum install fail2ban

chkconfig ‐‐levels 235 fail2ban on

/etc/init.d/fail2ban start

yum install rkhunter


26

23 Install SquirrelMail

To install the SquirrelMail webmail client, run...

... and restart Apache:

Then configure SquirrelMail:

We must tell SquirrelMail that we are using Courier‐IMAP/‐POP3:

Uppon Options, input the following:

D

courier

press any key

S

Q

One last thing we need to do is modify the file /etc/squirrelmail/config_local.php and comment out

the $default_folder_prefix variable ‐ if you don't do this, you will see the following error message in

SquirrelMail after you've logged in: Query: CREATE "Sent" Reason Given: Invalid mailbox name.

yum install squirrelmail

/etc/init.d/httpd restart

/usr/share/squirrelmail/config/conf.pl

vi /etc/squirrelmail/config_local.php

<?php

/**

* Local config overrides.

*

* You can override the config.php settings here.

* Don't do it unless you know what you're doing.

* Use standard PHP syntax, see config.php for examples.

*

* @copyright © 2002‐2006 The SquirrelMail Project Team


27

Now you can type in http://server1.example.com/webmail or http://192.168.0.100/webmail in your browser

to access SquirrelMail.

24 Install ISPConfig 3

Uninstall BIND and Dovecot so that the ISPConfig installer configures ISPConfig for MyDNS and Courier:

To install ISPConfig 3 from the latest released version, do this:

(Replace ISPConfig‐3.0.2.1.tar.gz with the latest version.)

The next step is to run

This will start the ISPConfig 3 installer. Uppon Options, input the following:

*/

//$default_folder_prefix = '';

?>

yum remove bind dovecot

cd /tmp

wget http://downloads.sourceforge.net/ispconfig/ISPConfig‐3.0.2.1.tar.gz?use_mirror=

tar xvfz ISPConfig‐3.0.2.1.tar.gz

cd ispconfig3_install/install/

php ‐q install.php


28

ENTER

ENTER

ENTER

ENTER

ENTER

ENTER

ENTER

ENTER

The installer automatically configures all underlying services, so no manual configuration is needed.

Afterwards you can access ISPConfig 3

under http://server1.example.com:8080/ or http://192.168.0.100:8080/. Log in with the username admin and

the password admin (you should change the default password after your first login)

The system is now ready to be used.
