*** Please write any Suggestion/Comment & Query in below box. ***

1. OS in preparation for RT
1.1 Enable System ETH0 to ONBOOT=yes :

# vi /etc/sysconfig/network-scripts/ifcfg-eth0

1.2 Disable firewall and SElinux :

# service iptables stop

# chkconfig iptables off

set SELINUX=disabled

# vi /etc/selinux/config

Restart system to make SELINUX changes take effect.

check SELINUX status

# sestatus

check if SSH Client is enabled

# service sshd status

If SSH Daemon is not running

# chkconfig sshd –- add

# chkconfig sshd on

2. Install the extra repositories.
Centos 5.x

# wget http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
# wget http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
# sudo rpm -Uvh remi-release-5*.rpm epel-release-5*.rpm

Centos 6.x

# wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
# sudo rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm

If disable repositories then open /etc/yum.repos.d/*.repo files and change enable=0 to 1.

# yum clean all
# yum update

3. Installing the necessary package which will be use for Request Tracker.

# yum install  rpm* nmap expect vsftpd net-snmp* ntp* subversion subversion-devel 
mysql mysql-server mysql-devel screen perl-Crypt- PasswdMD5 graphviz php-xml 
php-cli php-mhash php-ldap php-devel php-pdo php-imap php-readline 
php-ncurses php-soap php-snmp php-common php-mcrypt php-odbc php-mbstring 
php-gd php-bcmath php php-xmlrpc php-pear php-mysql php-dba mod_perl-devel

-- exclude=gcc-java* -- exclude=gcc4-java phpmyadmin mod_fcgid perl-GD 
perl-GnuPG-Interface perl-GraphViz perl-YAML

Restart System

4. Preparing PERL updates via CPAN.
4.1 Now install perl & cpan packages:

# yum install perl*
# yum install cpan

4.2 Start CPAN shell:

# perl -MCPAN -e shell

4.3 Set cpan to auto-follow dependencies by entering this in the cpan shell:

cpan[1]> o conf prerequisites_policy follow
cpan[1]> o conf commit
cpan[1]> install Bundle::CPAN

4.4 Reload CPAN and Index:

cpan[1]> reload cpan
cpan[1]> reload index

5. Preparing Web and Database Services
5.1 Edit httpd.conf to make the following changes:

# vi /etc/httpd/config/httpd.conf
- comment out
  # LoadModule suexec_module modules/mod_suexec.so
- set ServerName to the IP address of the machine
  ServerName 192.168.0.              << **your server ip here**
- remove index.html.var from DirectoryIndex so it reads
  DirectoryIndex index.html
- comment out
  # AddHandler type-map var
  # AddType text/html .shtml
  # AddOutputFilter INCLUDES .shtml

5.2 Enanble http daemon and mysql:

# chkconfig httpd on
# chkconfig mysqld on
# service httpd start
# service mysqld start

5.3 Test daemon and web server:

#service httpd status
#service mysqld status

http://Server IP Addr
You should be able to see Apache 2 Test Page powered by CentOS.

6. Installing phpMyAdmin which manage Database
6.1 we already installed phpMyAdmin from previous steps:

# yum list installed phpmyadmin

6.2 Now lets improve the security of your MySQL installation:

# /usr/bin/mysql_secure_installation

       Allow from 127.0.0.1
       Allow from ::1
       Allow from 192.168.0           << *** your server IP address here ***
    
…

6.4 Restart http service:

# service httpd restart

6.5 Test phpMyAdmin
http://Dervice IP Addr/phpMyAdmin/
Use the root password

6.6 If you wish to reset MySQL root password then follow :

# mysqladmin -u root password NEW_PASSWORD_HERE
# service mysqld restart

-–with-web-group=apache –-with-rt-group=rt –-prefix=/usr/local/rt 
–-enable-graphviz –-enable-gd –-enable-gpg

7.7 Run Fix Dependents script until all dependents are satisfied

# make fixdeps

if any issues when installing some dependencies perform

#cpan
cpan[1]>force install "dependency name"

7.8 Run Test Dependents script until all dependents are satisfied

# make testdeps

7.9 Install RT

# make install

8. Creating RT.conf file which will be used by Web Service httpd
8.1.Create rt.conf

#vi /etc/httpd/conf.d/rt.conf
AddDefaultCharset UTF-8
Alias /rt/NoAuth/images /usr/local/rt/share/html/NoAuth/images/
ScriptAlias /rt /usr/local/rt/sbin/rt-server.fcgi/
