ispconfig on Linux

Install Some Software

First we import the GPG keys for software packages:

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

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'

Install Quota

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

to enable quota.

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 5.3 repositories:

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

Afterwards we can install the needed packages with one single command (including the packages we need to build Courier-IMAP):

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

Install Courier-IMAP, Courier-Authlib, And Maildro

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:

useradd -m -s /bin/bash compileuser
passwd compileuser

We will need the sudo command later on so that the user compileusercan compile and install the rpm packages. But first, we must allow compileuser to run all commands using sudo:

Run

visudo

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

[...] root ALL=(ALL) ALL compileuser ALL=(ALL) ALL [...]

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

su compileuser

Next we create our build environment:

mkdir $HOME/rpm
mkdir $HOME/rpm/SOURCES
mkdir $HOME/rpm/SPECS
mkdir $HOME/rpm/BUILD
mkdir $HOME/rpm/SRPMS
mkdir $HOME/rpm/RPMS
mkdir $HOME/rpm/RPMS/i386
mkdir $HOME/rpm/RPMS/x86_64

echo "%_topdir $HOME/rpm" >> $HOME/.rpmmacros

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

cd /tmp
wget http://prdownloads.sourceforge.net/courier/courier-authlib-0.62.2.tar.bz2
wget http://prdownloads.sourceforge.net/courier/courier-imap-4.5.0.tar.bz2
wget http://prdownloads.sourceforge.net/courier/maildrop-2.1.0.tar.bz2

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

sudo rpmbuild -ta courier-authlib-0.62.2.tar.bz2

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):

cd $HOME/rpm/RPMS/x86_64

The command

ls -l

shows you the available rpm packages:

[compileuser@server1 x86_64]$ ls -l
total 608
-rw-r--r-- 1 root root 139745 May 25 14:52 courier-authlib-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 328419 May 25 14:52 courier-authlib-debuginfo-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 35322 May 25 14:52 courier-authlib-devel-0.62.2-1.x86_64.rpm

-rw-r--r-- 1 root root 13714 May 25 14:52 courier-authlib-pgsql-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 8358 May 25 14:52 courier-authlib-pipe-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 35287 May 25 14:52 courier-authlib-userdb-0.62.2-1.x86_64.rpm
[compileuser@server1 x86_64]$

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

sudo rpm -ivh courier-authlib-0.62.2-1.x86_64.rpm courier-authlib-mysql-0.62.2-1.x86_64.rpm courier-authlib-devel-0.62.2-1.x86_64.rpm

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:

cd /tmp
rpmbuild -ta courier-imap-4.5.0.tar.bz2

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):

cd $HOME/rpm/RPMS/x86_64

The command

ls -l

shows you the available rpm packages:

[compileuser@server1 x86_64]$ ls -l
total 1924
-rw-r--r-- 1 root root 139745 May 25 14:52 courier-authlib-0.62.2-1.x86_64.rpm

-rw-r--r-- 1 root root 35287 May 25 14:52 courier-authlib-userdb-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 compileuser compileuser 397262 May 25 15:04 courier-imap-4.5.0-3.x86_64.rpm
-rw-r--r-- 1 compileuser compileuser 940108 May 25 15:04 courier-imap-debuginfo-4.5.0-3.x86_64.rpm
[compileuser@server1 x86_64]$

You can install courier-imap like this:

sudo rpm -ivh courier-imap-4.5.0-3.x86_64.rpm

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

cd /tmp
sudo rpmbuild -ta maildrop-2.1.0.tar.bz2

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):

cd $HOME/rpm/RPMS/x86_64

The command

ls -l

shows you the available rpm packages:

[compileuser@server1 x86_64]$ ls -l
total 3188
-rw-r--r-- 1 root root 139745 May 25 14:52 courier-authlib-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 root root 328419 May 25 14:52 courier-authlib-debuginfo-0.62.2-1.x86_64.rpm

-rw-r--r-- 1 root root 35287 May 25 14:52 courier-authlib-userdb-0.62.2-1.x86_64.rpm
-rw-r--r-- 1 compileuser compileuser 397262 May 25 15:04 courier-imap-4.5.0-3.x86_64.rpm
-rw-r--r-- 1 compileuser compileuser 940108 May 25 15:04 courier-imap-debuginfo-4.5.0-3.x86_64.rpm
-rw-r--r-- 1 root root 299343 May 25 15:13 maildrop-2.1.0-3.x86_64.rpm

[compileuser@server1 x86_64]$

You can now install maildrop like this:

sudo rpm -ivh maildrop-2.1.0-3.x86_64.rpm

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

exit

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.

cd /usr/src
wget http://ftp-stud.fht-esslingen.de/pub/Mirrors/centos/5.3/os/SRPMS/postfix-2.3.3-2.1.el5_2.src.rpm
rpm -ivh postfix-2.3.3-2.1.el5_2.src.rpm

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

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/

Now we must edit the file postfix.spec:

vi postfix.spec

Change %define MYSQL 0 to %define MYSQL 1, add Patch0: postfix-2.3.3-vda.patch to the # Patches stanza, and finally add %patch0 -p1 -b .vda to the %setup -q stanza:

[...] %define MYSQL 1 [...] # Patches Patch0: postfix-2.3.3-vda.patch Patch1: postfix-2.1.1-config.patch Patch3: postfix-alternatives.patch Patch6: postfix-2.1.1-obsolete.patch Patch7: postfix-2.1.5-aliases.patch Patch8: postfix-large-fs.patch Patch9: postfix-2.2.5-cyrus.patch Patch10: postfix-CVE-2008-2936.patch [...] %setup -q # Apply obligatory patches %patch0 -p1 -b .vda %patch1 -p1 -b .config %patch3 -p1 -b .alternatives %patch6 -p1 -b .obsolete %patch7 -p1 -b .aliases %patch8 -p1 -b .large-fs %patch9 -p1 -b .cyrus %patch10 -p1 -b .CVE-2008-2936 [...]

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

rpmbuild -ba postfix.spec

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:

cd /usr/src/redhat/RPMS/x86_64

The command

ls -l

shows you the available packages:

[root@server1 x86_64]# ls -l
total 11732
-rw-r--r-- 1 root root 3940144 May 25 15:19 postfix-2.3.3-2.1.x86_64.rpm
-rw-r--r-- 1 root root 7999302 May 25 15:20 postfix-debuginfo-2.3.3-2.1.x86_64.rpm
-rw-r--r-- 1 root root 49760 May 25 15:19 postfix-pflogsumm-2.3.3-2.1.x86_64.rpm
[root@server1 x86_64]#

Pick the Postfix package and install it like this:

rpm -ivh postfix-2.3.3-2.1.x86_64.rpm

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

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

Configure Courier

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

chkconfig --levels 235 courier-imap on
/etc/init.d/courier-authlib restart
/etc/init.d/courier-imap restart

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.cnfand /usr/lib/courier-imap/etc/pop3d.cnf files. Because the .cnf files contain the 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...

cd /usr/lib/courier-imap/share/
rm -f imapd.pem
rm -f pop3d.pem

... 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:

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

[...] CN=server1.example.com [...]

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

[...] CN=server1.example.com [...]

Then we recreate both certificates...

./mkimapdcert
./mkpop3dcert

... and restart courier-authlib and courier-imap:

/etc/init.d/courier-authlib restart
/etc/init.d/courier-imap restart

Install Getmail

Getmail can be installed as follows:

yum install getmail

Set MySQL Passwords And Configure phpMyAdmin

Start MySQL:

chkconfig --levels 235 mysqld on
/etc/init.d/mysqld start

Then set passwords for the MySQL root account:

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

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):

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

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

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

[...] /* Authentication type */ $cfg['Servers'][$i]['auth_type'] = 'http'; [...]

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

chkconfig --levels 235 httpd on
/etc/init.d/httpd start

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.

Install Amavisd-new, SpamAssassin And ClamAV

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

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

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

chkconfig --levels 235 amavisd on
chkconfig --levels 235 clamd on
/usr/bin/freshclam
/etc/init.d/amavisd start
/etc/init.d/clamd start

... and create some necessary directories:

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

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

cd /etc/yum.repos.d/
wget http://centos.karan.org/kbsingh-CentOS-Extras.repo

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

vi /etc/yum.repos.d/kbsingh-CentOS-Extras.repo

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

[...] [kbs-CentOS-Testing] name=CentOS.Karan.Org-EL$releasever - Testing gpgcheck=0 gpgkey=http://centos.karan.org/RPM-GPG-KEY-karan.org.txt enabled=1 baseurl=http://centos.karan.org/el$releasever/extras/testing/$basearch/RPMS/

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

yum install php php-devel php-gd php-imap php-ldap php-mysql php-odbc php-pear php-xml php-xmlrpc php-eaccelerator php-mbstring php-mcrypt php-mhash php-mssql php-snmp php-soap php-tidy curl curl-devel perl-libwww-perl ImageMagick libxml2 libxml2-devel mod_fcgid php-cli httpd-devel

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

vi /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:

[...] ;error_reporting = E_ALL error_reporting = E_ALL & ~E_NOTICE [...] cgi.fix_pathinfo = 1

Next we install suPHP:

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 --with-apache-user=apache --with-setid-mode=owner --with-php=/usr/bin/php-cgi --with-logfile=/var/log/httpd/suphp_log --enable-SUPHP_USE_USERGROUP=yes
make
make install

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

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

LoadModule suphp_module modules/mod_suphp.so

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

vi /etc/suphp.conf

[global] ;Path to logfile logfile=/var/log/httpd/suphp.log ;Loglevel loglevel=info ;User Apache is running as webserver_user=apache ;Path all scripts have to be in docroot=/ ;Path to chroot() to before executing script ;chroot=/mychroot ; Security options allow_file_group_writeable=true allow_file_others_writeable=false 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 errors_to_browser=false ;PATH environment variable env_path=/bin:/usr/bin ;Umask to set, specify in octal notation umask=0077 ; Minimum UID min_uid=100 ; Minimum GID min_gid=100 [handlers] ;Handler for php-scripts x-httpd-suphp="php:/usr/bin/php-cgi" ;Handler for CGI-scripts x-suphp-cgi="execute:!self"

Finally we restart Apache:

/etc/init.d/httpd restart

Install PureFTPd

PureFTPd can be installed with the following command:

yum install pure-ftpd

Then create the system startup links and start PureFTPd:

chkconfig --levels 235 pure-ftpd on
/etc/init.d/pure-ftpd start

18 Install MyDNS

There's no MyDNS rpm package for the x86_64 architecture, and building MyDNS from the sources on CentOS 5.3 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:

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

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...

vi /etc/init.d/mydns

... and change

[...] # chkconfig: 345 52 50 [...]

to

[...] # chkconfig: 345 65 50 [...]

Then we create the startup links:

chkconfig --levels 235 mydns on

We don't start MyDNS now because it must be configured first - this will be done automatically by the ISPConfig 3 installer later on.

Install Vlogger And Webalizer

Vlogger and webalizer can be installed as follows:

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

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*

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!):

cd /tmp
wget http://olivier.sessink.nl/jailkit/jailkit-2.5.tar.gz
tar xvfz jailkit-2.5.tar.gz
cd jailkit-2.5
./configure
make
make install
rm -rf jailkit-2.5*

21 Install fail2ban

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

yum install fail2ban

chkconfig --levels 235 fail2ban on
/etc/init.d/fail2ban start

nstall rkhunter

rkhunter can be installed as follows:

yum install rkhunter

Install SquirrelMail

To install the SquirrelMail webmail client, run...

yum install squirrelmail

... and restart Apache:

/etc/init.d/httpd restart

Then configure SquirrelMail:

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

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

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.

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 &copy; 2002-2006 The SquirrelMail Project Team * @license http://opensource.org/licenses/gpl-license.php GNU Public License * @version $Id: config_local.php,v 1.2 2006/07/11 03:33:47 wtogami Exp $ * @package squirrelmail * @subpackage config */ //$default_folder_prefix = ''; ?>

Now you can type in http://server1.example.com/webmail or http://yourdomain.com/webmail in your browser to access SquirrelMail.

Install ISPConfig 3

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

cd /tmp
wget http://downloads.sourceforge.net/ispconfig/ISPConfig-3.0.1.3.tar.gz?use_mirror=
tar xvfz ISPConfig-3.0.1.3.tar.gz
cd ispconfig3_install/install/

(Replace ISPConfig-3.0.1.3.tar.gz with the latest version.)

The next step is to run

php -q install.php

This will start the ISPConfig 3 installer:

[root@server1 install]# php -q install.php

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):
