3Installing RT

3.1Prerequisites

Ensure that you have a installation of CentOS 4.4 or Redhat EL 4 with following:

• 
  Apache Web Server 2.0.52
  
• 
  MySQL 4.1.20 (both these come with the CentOS 4.4)
  

If these are not installed then first install them

IMPORTANT: the 'selinux must be disabled' for RT to work properly

NOTE: this installation uses FastCGI instead of mod_perl. This is because RT 3.4.* onwards requires mod_perl 2.x versions and by default mod_perl 1.99 comes with CentOS 4.x and RHEL4. This creates run time issues so instead use FastCGI

3.2Installing webmin

Download and install webmin as (this helps starting, closing apache and mysql):

wget ftp://ftp.pbone.net/mirror/ftp.sourceforge.net/pub/sourceforge/w/we/webadmin/webmin-1.370-1.noarch.rpm rpm –I webmin-1.370-1.noarch.rpm

3.3 Perl dependencies

Fulfil few dependencies that perl has. It can be done as:

yum install httpd-devel apr-devel mysql mysqlclient10 mysql-server mysql-devel gcc sendmail-cf

Most of these are already installed on the system by default. if any package is not installed then it is installed by above command installed packages can be checked by command yum list
*

Update few packages to latest versions as:

yum update freetype-devel gd-devel libjpeg-devel libpng-devel xorg-x11-devel

3.4 Installing FastCGI

wget http://www.fastcgi.com/dist/mod_fastcgi-2.4.2.tar.gz tar -zxvf mod_fastcgi-2.4.2.tar.gz cd mod_fastcgi-2.4.2 cp Makefile.AP2 Makefile vi Makefile

Modify Makefile for location of apache 2 installation:

top_dir = /etc/httpd make make install

Create file FastCGI.conf

touch /etc/httpd/conf.d/FastCGI.conf vi /etc/httpd/conf.d/FastCGI.conf

Add following lines to load FastCGI module (FastCGI.conf):

LoadModule fastcgi_module modules/mod_fastcgi.so FastCgiServer /opt/rt3/bin/mason_handler.fcgi -idle-timeout 120 -processes 8 FastCgiConfig -restart

FastCGI wants to have a place to put its logs, and permission to do so:

mkdir -p /etc/httpd/logs/fastcgi/dynamic chown -R apache:apache /etc/httpd/logs/fastcgi

3.5 Starting MySQL

Turn on MySQL server using webmin. MySQL is located under 'servers' link in webmin.

Change root password as: (this is required in later stage when RT database is created)

mysqladmin -u root password rootpassword

3.6 Installing ncftpget

ncftpget is required to fulfil some dependencies so download and install it:

wget -c ftp://ftp.ncftp.com/ncftp/binaries/ncftp-3.2.1-linux-x86-glibc2.3-export.tar.gz tar -xvzf ncftp-3.2.1-linux-x86-glibc2.3-export.tar.gz cd ncftp-3.2.1 make install

3.7 RT pre-installation

RT requires its own group, so add it:

groupadd rt

RT gets initiated by apache, so add apache to the rt group:

vi /etc/group

Change the line:

rt:x:501:

To read:

rt:x:501:apache

Change permissions on /etc/httpd/logs

chmod -Rf 755 /etc/httpd/logs

Install all these modules using command rpm as:

rpm -i

Set up CPAN initially to download remaining perl modules

perl -MCPAN -e shell

From within CPAN download remaining perl modules.

cpan> install Bundle::CPAN cpan> quit
