yum install mysql mysql-server
yum install php php-cli php-common php-devel php-gd php-mbstring php-mysql php-xml php-imap php-zip php-zlib php-pdo

Start service Apache web server and MySQL also enable it to start on boot of the server:

service httpd start
service mysql start
chkconfig httpd on
chkconfig mysqld on

Step 3. Install osTicket.

Download the latest stable version of osTicket, At the moment of writing this article it is version 1.9.8:

mkdir -p /opt/osticket
wget http://osticket.com/sites/default/files/download/osTicket-v1.9.12.zip
unzip -d /opt/osticket /tmp/osTicket-v1.9.12.zip 
ln -s /opt/osticket/upload /var/www/html/support

We will need to change some folders permissions:

chown apache: -R /var/www/html/support /opt/osticket

Run the following commands to finalize the installation of osTicket:

cd /var/www/html/support 
cp include/ost-sampleconfig.php include/ost-config.php

Step 4. Configure MySQL Database for osTicket.

By default, MySQL is not hardened. You can secure MySQL using the mysql_secure_installation script. you should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MySQL.


Next, we will need to log in to the MySQL console and create a database for osTicket. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MySQL root password and hit Enter. Once you are logged in to your database server you need to create a database for the osTicket software:

mysql> create database support;
mysql> grant all on support.* to support@localhost identified by 'support';
mysql> \q

Step 5. Configure Apache webserver.

Create a new virtual host directive in Apache so you can access the osTicket installation on your server using your domain name:

nano /etc/httpd/conf/httpd.conf

Add the following lines at the end of the file:

<VirtualHost *:80>
 ServerAdmin admin@yourdomain.com
 DocumentRoot /var/www/html/support
 ServerName support.yourdomain.com
 ServerAlias www.support.yourdomain.com
 <Directory /var/www/html/support/>
 Options FollowSymLinks
 AllowOverride All
 ErrorLog /var/log/httpd/support.yourdomain.com-error_log
 CustomLog /var/log/httpd/support.yourdomain.com-access_log common

Restart the Apache service for the changes to take effect:

service httpd restart

Step 6. Accessing osTicket.

osTicket will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://support.yourdomain.com or http://support.server-ip and complete the required steps to finish the installation.
