14 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.

 

15 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 the centos.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

 

17 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.

 

19 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*

 

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!):

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

 

22 Install rkhunter

rkhunter can be installed as follows:

yum install rkhunter
