How to Install TestLink on CentOS 7

TestLink is a free and open source web based test management system that facilitates software quality assurance. It is developed and maintained by teamtest and it is written in PHP. TestLink offers support for test cases, test suites, test plans, test projects and user management, as well as various reports and statistics. Some of its features are listed below:

  • user roles and management
  • test plans
  • grouping of test cases in test specifications
  • bug tracking system integration
  • integration with other software using a provided API
  • customization of the user interface using Smarty templates
  • reports, charts and monitors
  • support for testing different builds of the software

Prerequisites

You'll need a centos 7 server and root privileges to install TestLink. You can switch from non root user to root user using sudo -i command.

Updating System

Before going through the installation process it is highly recommended to update your system and upgrade all available packages run the command below and it'll do the job for you.

yum -y update

Installing Apache Web Server

Once the system is updated, you can install the dependencies required. To install TestLink you will need to install the Apache web server along with MaraiDB and PHP with a few extensions.

Run the following command to install the Apache web server.

yum -y install httpd

Now you can start Apache and enable it to start at boot time, using the following commands.

systemctl start httpd.service systemctl enable httpd.service

You can check the status of Apache web server using the following command. systemctl status httpd

You should see following output:

[root@Sajid ~]# systemctl status httpd
● httpd.service - The Apache HTTP Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)

We will need to install MariaDB for database purposes for TestLink. MariaDB 5.5 is shipped in the default CentOS 7 repository, so just run this command to install MariaDB.

yum -y install mariadb-server

Now you'll have to start the MariaDB service and enable it to start at the boot time like we have done before for apache server, to do so please run following command.

systemctl start mariadb.service systemctl enable mariadb.service

You can check status of mariaDB using this below given command and you should see following output.

systemctl status mariadb.service
[root@Sajid ~]# systemctl status mariadb.service

We recommend you make sure that this installation is secure and to do so run following command.

mysql_secure_installation

You'll be asked to provide root password so enter appropriate password and answer yes to all questions by pressing Y.

Now you'll have to create a database for TestLink so please follow the instructions.

mysql -u root -p

You'll be asked to enter password so simply enter a password and now execute the following queries to create a new database.

CREATE DATABASE testlink_data;

The above query will create a database named testlink_data. For the database you can use any name you prefer in the place of testlink_data. Make sure that you use semicolon at the end of each query as a query always ends with a semicolon. Once the database is created you can create a new user and grant the required permissions to the user for the database.

CREATE USER 'testlink_user'@'localhost' IDENTIFIED BY 'StrongPassword';

The above query will create a user with username testlink_user. You can use any preferred username instead of testlink_user. Replace StrongPassword with a strong password.

Now provide the appropriate privileges to your database user over the database you have created. Run the following query to do so.

GRANT ALL PRIVILEGES ON testlink_data.* TO 'testlink_user'@'localhost';

Now run the following query to immediately apply the changes on the database privileges.

FLUSH PRIVILEGES;

Now you can exit from MariaDB prompt using following command.

exit.

We will have to install PHP. To do so run following commands as shown below.

cd yum -y install epel-release rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpmyum install mod_php71w php71w-mysqlnd php71w-common php71w-gd php71w-ldap php71w-cli php71w-mcrypt php71w-xml -y

Next we will have to change some PHP settings to fulfill TestLink requirements so please run below commands.

cp /etc/php.ini /etc/php.ini.bak sed -i "s/session.gc_maxlifetime = 1440/session.gc_maxlifetime = 2880/" /etc/php.inised -i "s/max_execution_time = 30/max_execution_time = 120/" /etc/php.ini

Next you'll have to restart your apache web server to load new components that we just configured and use following command to restart apache web server.

systemctl restart httpd.service

Installing TestLink

Once we have installed all required dependencies now we are ready to install TestLink on centos server so first download the latest stable release of TestLink from TestLink GitHub repository and unzip the archive file to the web root directory. Run the following commands, it will do the job for you. wget https://github.com/TestLinkOpenSourceTRMS/testlink-code/archive/1.9.16.tar.gz

tar -zxvf 1.9.16.tar.gz -C /var/www/html chown -R apache:apache /var/www/html/testlink-code-1.9.16

Next, you'll have to create a custom configuration file for TestLink, you can do so using this command.

cp /var/www/html/testlink-code-1.9.16/custom_config.inc.php.example /var/www/html/testlink-code-1.9.16/custom_config.inc.php

Next, we will have to edit custom configuration file using any text editor here we are using nano text editor you can also install it using yum -y install nano

nano /var/www/html/testlink-code-1.9.16/custom_config.inc.php

Find these following lines in file:

// $tlCfg->log_path = '/var/testlink-ga-testlink-code/logs/'; /* unix example */

// $g_repositoryPath = '/var/testlink-ga-testlink-code/upload_area/'; /* unix example */

Now replace them with these lines then save the file and exit from text editor.

$tlCfg->log_path = '/var/www/html/testlink-code-1.9.16/logs/';

$g_repositoryPath = '/var/www/html/testlink-code-1.9.16/upload_area/';

Creating a Virtual Host

You'll need to create a virtual host for TestLink to finish the installation process. You can use any text editor for creating virtual host here we are using nano text editor. Run following command to create a virtual host configuration file. nano /etc/httpd/conf.d/testlink.conf

Add below given content to the configuration file and replace server admin and name with your own.

<VirtualHost *:80>
ServerAdmin admin@example.com
DocumentRoot /var/www/html/testlink-code-1.9.16/
ServerName testlink.example.com
ServerAlias www.testlink.example.com
<Directory /var/www/html/testlink-code-1.9.16/>
Options FollowSymLinks
AllowOverride All
Order allow,deny
allow from all
</Directory>
ErrorLog /var/log/httpd/testlink.example.com-error_log
CustomLog /var/log/httpd/testlink.example.com-access_log common
</VirtualHost>

Save the file and exit from the text editor, finally restart your apache web server to apply all the changes.

systemctl restart httpd

Next you'll have to modify firewall rules and if in case you don't have firewalld services installed on your server then you can install it using yum -y install firewalld and you can start it using systemctl start firewalld

Next run these below given command to modify the firewalld rules.

firewall-cmd --zone=public --permanent --add-service=http firewall-cmd --reload

Web Access

Open up your favorite web browser and visit http://yourserverIP to finish this installation. Accept the license and terms and conditions to the continue with installation process.

On the database setup page provide following database information and click on Process TestLink Setup button.

Database Type: MySQL/MariaDB (5.6+ / 10.+)
Database host: localhost
Database name: testlink_data
Table prefix: <LEAVE IT EMPTY>
Database admin login: root
Database admin password: <your-MariaDB-root-password>
TestLink DB login: testlink_user
TestLink DB password: yourpassword

Next you'll see a log in page so use admin as both username and password for logging in to the admin dashboard.
