14 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:
sa-update
chkconfig --levels 235 amavisd on
chkconfig --levels 235 clamd on
/usr/bin/freshclam
/etc/init.d/amavisd start
/etc/init.d/clamd start
15 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.
We can install Apache2with 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-eaccelerator 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 ; to use SCRIPT_FILENAME rather than PATH_TRANSLATED. ; http://www.php.net/manual/en/ini.core.php#ini.cgi.fix-pathinfo cgi.fix_pathinfo=1 [...] |
Next we install suPHP (there is a mod_suphp package available in the repositories, but unfortunately it isn't compatible with ISPConfig, therefore we have to build suPHP ourselves):
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
15.1 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 CentOS 6.0, there's no mod_ruby package available, so we must compile it ourselves. First we install some prerequisites:
yum install httpd-devel ruby ruby-devel
Next we download and install mod_ruby as follows:
cd /tmp
wget http://modruby.net/archive/mod_ruby-1.3.0.tar.gz
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
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/mod_ruby.so 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
)
15.2 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/mod_auth_digest.so [...] LoadModule dav_module modules/mod_dav.so [...] LoadModule dav_fs_module modules/mod_dav_fs.so [...] |
If you have to modify /etc/httpd/conf/httpd.conf, don't forget to restart Apache afterwards:
/etc/init.d/httpd restart
16 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. "server1.example.com").
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.
17 Install BIND
We can install BIND as follows:
yum install bind bind-utils
Next open /etc/sysconfig/named...
vi /etc/sysconfig/named
... and make sure that the ROOTDIR=/var/named/chroot line is comment out:
# 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) #ROOTDIR=/var/named/chroot |
Make a backup of the existing /etc/named.conf file and create a new one as follows:
cp /etc/named.conf /etc/named.conf_bak
cat /dev/null > /etc/named.conf
vi /etc/named.conf
//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//
options {
listen-on port 53 { any; };
listen-on-v6 port 53 { any; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
allow-query { any; };
recursion no;
allow-recursion { none; };
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
zone "." IN {
type hint;
file "named.ca";
};
include "/etc/named.conf.local";
|
Create the file /etc/named.conf.local that is included at the end of /etc/named.conf (/etc/named.conf.local will later on get populated by ISPConfig if you create DNS zones in ISPConfig):
touch /etc/named.conf.local
Then we create the startup links and start BIND:
chkconfig --levels 235 named on
/etc/init.d/named start
18 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
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*
19 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-2.14.tar.gz
tar xvfz jailkit-2.14.tar.gz
cd jailkit-2.14
./configure
make
make install
cd ..
rm -rf jailkit-2.14*
20 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
21 Install rkhunter
rkhunter can be installed as follows:
yum install rkhunter
