Download TeamCity Firstly we will download the TeamCity tar archive from the official website.

wget https://download.jetbrains.com/teamcity/TeamCity-2020.1.3.tar.gz

tar xvf TeamCity-2020.1.3.tar.gz

Install TeamCity Now we will install TeamCity.

mkdir /opt/teamcity mv TeamCity /opt/teamcity

Download PostgreSQL JDBC driver We need to download PostgreSQL JDBC driver in order to use PostgreSQL database for TeamCity. You can download it from this link also or use the following command to download via yum.

mkdir -p /opt/teamcity/.BuildServer/lib/jdbc/ https://repo1.maven.org/maven2/org/postgresql/postgresql/42.2.16/postgresql-42.2.16.jar

wget https://jdbc.postgresql.org/download/postgresql-42.2.16.jar -P /opt/teamcity/.BuildServer/lib/jdbc/

We will create a startup script to start teamcity. Create a new file in /etc/systemd/system/teamcity.service.

vim /etc/systemd/system/teamcity.service

[Unit] Description=TeamCity Server After=network.target

[Service] Type=forking PIDFile=/opt/teamcity/logs/teamcity-server.pid ; Make sure the CATALINA_PID env variable is setup in $TEAMCITY_HOME/bin/catalina.sh ExecStart=/opt/teamcity/bin/teamcity-server.sh start ExecStop=/opt/teamcity/bin/teamcity-server.sh stop

[Install] WantedBy=multi-user.target Enable and Start TeamCity Services Now we will enable and start TeamCity using systemctl. Before we need to reload the daemon because we have created new service file.

systemctl enable teamcity

systemctl start teamcity

TeamCity web interface Now we will go to the web interface to continue our TeamCity installation. Go to ip-address:8111

Step 1: Change the Data Directory

Here we will change the data directory to /opt/teamcity/.BuildServer
