The Perfect Server - Fedora 15 x86_64 [ISPConfig 3] - Page 5

15 Install Amavisd-new, SpamAssassin And ClamAV

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

yum install amavisd-new spamassassin clamav clamav-data clamav-server clamav-update unzip bzip2 perl-DBD-mysql

When we installed ClamAV, a cron job got installed that tries to update the ClamAV virus database every three hours. But this works only if we enable it in /etc/sysconfig/freshclam and /etc/freshclam.conf:

vi /etc/sysconfig/freshclam

Comment out the FRESHCLAM_DELAY line at the end:

## When changing the periodicity of freshclam runs in the crontab,
## this value must be adjusted also. Its value is the timespan between
## two subsequent freshclam runs in minutes. E.g. for the default
## | 0 */3 * * *  ...
## crontab line, the value is 180 (minutes).

## A predefined value for the delay in seconds. By default, the value is
## calculated by the 'hostid' program. This predefined value guarantees
## constant timespans of 3 hours between two subsequent freshclam runs.
## This option accepts two special values:
## 'disabled-warn'  ...  disables the automatic freshclam update and
##                         gives out a warning
## 'disabled'       ...  disables the automatic freshclam silently

### !!!!! REMOVE ME !!!!!!
### REMOVE ME: By default, the freshclam update is disabled to avoid
### REMOVE ME: network access without prior activation

vi /etc/freshclam.conf

Comment out the Example line:

# Comment or remove the line below.

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

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

Next do this:

rm -f /var/spool/amavisd/clamd.sock
mkdir /var/run/clamav.amavisd /var/run/clamd.amavisd /var/run/amavisd
chown amavis /var/run/clamav.amavisd
chown amavis /var/run/clamd.amavisd
chown amavis /var/run/amavisd
ln -sf /var/spool/amavisd/clamd.sock /var/run/clamav.amavisd/clamd.sock
ln -sf /var/spool/amavisd/clamd.sock /var/run/clamd.amavisd/clamd.sock
/etc/init.d/clamd.amavisd restart

Fedora 15 has a /run directory for storing runtime data. /run is now a tmpfs, and /var/run and /var/lock are now bind mounted to /run and /run/lock from tmpfs, and hence emptied on reboot (see for more details).

This means that after a reboot, the directories /var/run/clamav.amavisd, /var/run/clamd.amavisd, and /var/run/amavisd that we have just created will not exist anymore, and therefore clamd and amavisd will fail to start. Therefore we create the file /etc/tmpfiles.d/amavisd.conf now that will create these directories at system startup (see for more details):

vi /etc/tmpfiles.d/amavisd.conf

D /var/run/clamav.amavisd 0755 amavis root -
D /var/run/clamd.amavisd 0755 amavis root -
D /var/run/amavisd 0755 amavis root -


16 Installing 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.

We can install Apache2 with mod_php5, mod_fcgid, and PHP5 as follows:

yum install php php-devel php-gd php-imap php-ldap php-mysql php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt 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 uncomment cgi.fix_pathinfo=1:

;error_reporting = E_ALL & ~E_DEPRECATED
error_reporting = E_ALL & ~E_NOTICE
; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for CGI.  PHP's
; previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to not grok
; what PATH_INFO is.  For more information on PATH_INFO, see the cgi specs.  Setting
; this to 1 will cause PHP CGI to fix its paths to conform to the spec.  A setting
; of zero causes PHP to behave as before.  Default is 1.  You should fix your scripts

Next we install suPHP:

cd /tmp
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 install

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

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

LoadModule suphp_module modules/

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

vi /etc/suphp.conf

;Path to logfile


;User Apache is running as

;Path all scripts have to be in

;Path to chroot() to before executing script

; Security options

;Check wheter script is within DOCUMENT_ROOT

;Send minor error messages to browser

;PATH environment variable

;Umask to set, specify in octal notation

; Minimum UID

; Minimum GID

;Handler for php-scripts

;Handler for CGI-scripts

Finally we restart Apache:

/etc/init.d/httpd restart


16.1 Ruby

Starting with version 3.0.3, ISPConfig 3 has built-in support for Ruby. Instead of using CGI/FastCGI, ISPConfig depends on mod_ruby being available in the server's Apache.

For Fedora 15, there's no mod_ruby package available, so we must compile it ourselves. First we install some prerequisites:

yum install ruby ruby-devel

Next we download and install mod_ruby as follows:

cd /tmp
tar zxvf mod_ruby-1.3.0.tar.gz
cd mod_ruby-1.3.0/
./configure.rb --with-apr-includes=/usr/include/apr-1
make install

Finally we must add the mod_ruby module to the Apache configuration, so we create the file /etc/httpd/conf.d/ruby.conf...

vi /etc/httpd/conf.d/ruby.conf

LoadModule ruby_module modules/
RubyAddPath /1.8

... and restart Apache:

/etc/init.d/httpd restart

(If you leave out the RubyAddPath /1.8 directive, you will see errors like the following ones in Apache's error log when you call Ruby files:

[Thu May 26 02:05:05 2011] [error] mod_ruby: ruby:0:in `require': no such file to load -- apache/ruby-run (LoadError)
[Thu May 26 02:05:05 2011] [error] mod_ruby: failed to require apache/ruby-run
[Thu May 26 02:05:05 2011] [error] mod_ruby: error in ruby



16.2 WebDAV

WebDAV should already be enabled, but to check this, open /etc/httpd/conf/httpd.conf and make sure that the following three modules are active:

vi /etc/httpd/conf/httpd.conf

LoadModule auth_digest_module modules/
LoadModule dav_module modules/
LoadModule dav_fs_module modules/

If you have to modify /etc/httpd/conf/httpd.conf, don't forget to restart Apache afterwards:

/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

Now we configure PureFTPd to allow FTP and TLS sessions. FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure.

OpenSSL is needed by TLS; to install OpenSSL, we simply run:

yum install openssl

Open /etc/pure-ftpd/pure-ftpd.conf...

vi /etc/pure-ftpd/pure-ftpd.conf

If you want to allow FTP and TLS sessions, set TLS to 1:

# This option can accept three values :
# 0 : disable SSL/TLS encryption layer (default).
# 1 : accept both traditional and encrypted sessions.
# 2 : refuse connections that don't use SSL/TLS security mechanisms,
#     including anonymous sessions.
# Do _not_ uncomment this blindly. Be sure that :
# 1) Your server has been compiled with SSL/TLS support (--with-tls),
# 2) A valid certificate is in place,
# 3) Only compatible clients will log in.

TLS                      1

In order to use TLS, we must create an SSL certificate. I create it in /etc/ssl/private/, therefore I create that directory first:

mkdir -p /etc/ssl/private/

Afterwards, we can generate the SSL certificate as follows:

openssl req -x509 -nodes -days 7300 -newkey rsa:2048 -keyout /etc/ssl/private/pure-ftpd.pem -out /etc/ssl/private/pure-ftpd.pem

Country Name (2 letter code) [XX]: <-- Enter your Country Name (e.g., "DE").
State or Province Name (full name) []:
<-- Enter your State or Province Name.
Locality Name (eg, city) [Default City]:
<-- Enter your City.
Organization Name (eg, company) [Default Company Ltd]:
<-- Enter your Organization Name (e.g., the name of your company).
Organizational Unit Name (eg, section) []:
<-- Enter your Organizational Unit Name (e.g. "IT Department").
Common Name (eg, your name or your server's hostname) []:
<-- Enter the Fully Qualified Domain Name of the system (e.g. "").
Email Address []:
<-- Enter your Email Address.

Change the permissions of the SSL certificate:

chmod 600 /etc/ssl/private/pure-ftpd.pem

Finally restart PureFTPd:

/etc/init.d/pure-ftpd restart

That's it. You can now try to connect using your FTP client; however, you should configure your FTP client to use TLS.


18 Install BIND

We can install BIND as follows:

yum install bind bind-utils

Next open /etc/sysconfig/named...

vi /etc/sysconfig/named

... and comment out the ROOTDIR=/var/named/chroot line:

# BIND named process options
# ~~~~~~~~~~~~~~~~~~~~~~~~~~
# Currently, you can use the following options:
# ROOTDIR="/var/named/chroot"  --  will run named in a chroot environment.
#                            you must set up the chroot environment
#                            (install the bind-chroot package) before
#                            doing this.
#       NOTE:
#         Those directories are automatically mounted to chroot if they are
#         empty in the ROOTDIR directory. It will simplify maintenance of your
#         chroot environment.
#          - /var/named
#          - /etc/pki/dnssec-keys
#          - /etc/named
#          - /usr/lib64/bind or /usr/lib/bind (architecture dependent)
#         Those files are mounted as well if target file doesn't exist in
#         chroot.
#          - /etc/named.conf
#          - /etc/rndc.conf
#          - /etc/rndc.key
#          - /etc/named.rfc1912.zones
#          - /etc/named.dnssec.keys
#          - /etc/named.iscdlv.key
#       Don't forget to add "$AddUnixListenSocket /var/named/chroot/dev/log"
#       line to your /etc/rsyslog.conf file. Otherwise your logging becomes
#       broken when rsyslogd daemon is restarted (due update, for example).
# OPTIONS="whatever"     --  These additional options will be passed to named
#                            at startup. Don't add -t here, use ROOTDIR instead.
# KEYTAB_FILE="/dir/file"    --  Specify named service keytab file (for GSS-TSIG)
# DISABLE_ZONE_CHECKING  -- By default, initscript calls named-checkzone
#                           utility for every zone to ensure all zones are
#                           valid before named starts. If you set this option
#                           to 'yes' then initscript doesn't perform those
#                           checks.

Then we create the startup links:

chkconfig --levels 235 named on

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


19 Install Vlogger, Webalizer, And AWStats

Vlogger, webalizer, and AWStats can be installed as follows:

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

cd /tmp
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
tar xvfz jailkit-2.14.tar.gz
cd jailkit-2.14
make install
cd ..
rm -rf jailkit-2.14*


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

Problem starting named in Fedora 15 (x86-64) after install ISPConfig 3:

 [root@web install]# service named start

Starting named (via systemctl):  Job failed. See system logs and 'systemctl status' for details.
