Install MySQL 5.5 on CentOS
- Switch to root user:
$ sudo su - List all mysql packages to be installed in CentOS
If an older version than MySQL 5.5 is installed, please follow step #3. Otherwise, please follow step #4# yum list installed | grep -i mysql - If an older version than MySQL 5.5 is installed, remove it (qTest supports MySQL version 5.5+).
# yum remove mysql mysql-* - Install MySQL 5.5.
- Update Remi repository
#rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm # rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm - Install mysql 5.5
# yum install --enablerepo=remi,remi-test list mysql mysql-server

If your firewall is enabled, make sure that the port is not blocked by the firewall. Click here for the instructions.
- After MySQL installation is complete, please make sure that the transaction isolation level is set to READ-COMMITTED.
Access to your MySQL instance. Check if variable tx_isolation's value is READ-COMMITTED by executing the following SQL statement
If it is not READ-COMMITTED: under MySQL's installation directory, search for file my.cnfmysql> SHOW VARIABLES LIKE 'tx_isolation';
Open the file above, add the following text to the end of section [mysqld].#find / -name "my.cnf"
Save the file.transaction-isolation = READ-COMMITTED - This step is only required if you are deploying qTest with load balancing: Check if the maximum number of connections of MySQL server is appropriate to the number of qTest instances in the cluster. Given there are n qTest application servers in your cluster, then the appropriate number of connections to MySQL should be: 100 * (n + 1) + 10
Access to your MySQL instance and execute this command:
If the maximum number of connection is less than the appropriate number, search for file my.cnf under MySQL installation directory, open it and add the text below to the of section [mysqld].mysql> SHOW VARIABLES LIKE ‘max_connections’;
Save the file.max_connections=[the_appropriate_number] - Restart the service.
Verify information of transaction isolation level is set to READ-COMMITTED and the maximum number of connections#service mysql restart#mysql -u [YOUR_MySQL_USER] -p mysql>SHOW VARIABLES LIKE 'tx_isolation'; mysql>SHOW VARIABLES LIKE ‘max_connections’;
Install MySQL 5.5 on Ubuntu
- Switch to root user:
$ sudo su - List all packages have been installed in Ubuntu and check if MySQL is in the list.
If an older version than MySQL 5.5 is installed, please follow step #3. Otherwise, please follow step #4.# dpkg -l | grep '^ii' - If an older version than MySQL 5.5 is installed, remove it (qTest supports MySQL version 5.5+).
# sudo apt-get remove mysql-server mysql-client mysql-common # sudo apt-get autoremove # sudo apt-get autoclean - This step is optional. If the version included in your version of Ubuntu is not the one you want, you can use the MySQL Apt Repository. Please refer to http://dev.mysql.com/downloads/repo/apt/ to set the repository.
- Install MySQL
# apt-get update # apt-get install mysql-client-5.5 mysql-server-5.5 mysql-common - After the installation is done, check for MySQL's service name in your machine by the following command:
From the command's output, search for mysql to get its full name.# chkconfigexplorerd off friendly-recovery off grub-common on hostname off hwclock off hwclock-save off irqbalance off killprocs on module-init-tools off mysql off //this is MySQL's service name network-interface off network-interface-container off network-interface-security off networking 0 ondemand on - Check if the service is running.

Install MySQL Connector/J
Important:
- qTest works with MySQL Connector/J version 5.1.34+.
- It needs to be installed on every server instance in which you are installing qTest.
Access to MySQL Connector/J's download page: http://dev.mysql.com/downloads/connector/j/
Select Platform Independent.
Download the TAR Archive.
After the file has been downloaded, extract it. In the extracted directory, search for the jar file: mysql-connector-java-5.1.35.jar. You will need to specify the path to this file when installing qTest.
Install RabbitMQ
Important:
- In case you are deploying qTest with load balancing, you are required to install RabbitMQ. If not, you can skip installing this.
Follow this instruction to download and install RabbitMQ.
After you have installed RabbitMQ successfully, run the following commands to configure it.
rabbitmq-plugins enable rabbitmq_stomp
rabbitmq-plugins enable rabbitmq_management
rabbitmqctl add_user qtest [qtest_password]//to create user qtest, specify his password
rabbitmqctl add_user rabbitmqadmin [rabbitmqadmin_password]//to create user rabbitmqadmin, specify his password
rabbitmqctl set_user_tags rabbitmqadmin administrator
rabbitmqctl add_vhost qtest-onpremise //to create a virtual host named qtest-onpremise
rabbitmqctl set_permissions -p qtest-onpremise qtest ".*" ".*" ".*" //grant user qtest the access to virtual host qtest-onpremise
Execute the command below to view amqp port and stomp port. You will need to use these ports while installing qTest.
sudo rabbitmqctl status | grep "amqp\|stomp"
Install PostgreSQL on CentOS
Important:
- All steps need to be executed under Root account
From the terminal, run the following command to install PostgreSQL. You can browse http://yum.postgresql.org and find your correct RPM.
# yum update
# yum install http://yum.postgresql.org/9.3/redhat/rhel-6-x86_64/pgdg-centos93-9.3-1.noarch.rpm
# yum install postgresql93-server postgresql93-contrib
Check for PostgreSQL's service name in your machine by the following command:
# chkconfig
From the command's output, search for postgresql to get its full name.

If you want PostgreSQL to start automatically when the OS starts:
# chkconfig postgresql-9.3 on //enable postgresql
# service postgresql-9.3 start //start the service
Enable remote access to PostgreSQL database server:
- Search for file pg_hba.conf in Postgresql's installation directory.
Edit the above file. Append the following configuration line, in which [IP_Address] is the IP of the machine from which you remotely connect to PostgreSQL server.# find / -name "pg_hba.conf" /var/lib/pgsql/9.3/data/pg_hba.conf //this is the resulthost all all [IP_Address]/24 password - Search for file postgresql.conf in Postgresql's installation directory.
Edit the above file. Search for property listen_address and modify it to (remove # at the beginning of the line if it is there):# find / -name "postgresql.conf" /var/lib/pgsql/9.3/data/postgresql.conf //this is the resultlisten_addresses = '*'
Change password for postgres database user.
# sudo -u postgres psql
postgres=# \password
Enter new password: // enter password of postgres
Enter it again:
postgres=#After PostgreSQL has been successfully installed, you will need to create a database schema. It will be used when installing qTest Sessions.
- Switch to postgres user:
#su - postgres - Create a database schema using the command below:
For example:createdb [YOUR_DATABASE_NAME]-bash-4.1$ createdb testdb //testdb is the database schema name - Connect to the database that matches your username:
-bash-4.1$ psql - List out existing schema to check if the above one has been successfully created:
