Install a Teamcity v9.x CentOS Build Agent
Use 'Agent Push' to install a build agent using ssh with public key authentication.
TeamCity Authentication
Ensure the Teamcity server user has a ssh key pair. (Note: if password based ssh authentication is used then this step can be skipped)
# su - teamcity $ ssh-keygen -b 4096 $ cat ~/.ssh/id_rsa.pub
The public key text from 'id_rsa.pub' will need to be put into the 'authorized_keys' file of the Teamcity Ageny user (below).
Build Agent
Install prerequisites for the agent:
# yum install java-1.8.0-openjdk unzip wget java-1.8.0-openjdk-devel
Create a Teamcity build agent account on the agent machine. Add the Teamcity servers ssh public key to the 'authorized_keys' file of the Teamcity Agent account.
# adduser -r -m -c "TeamCity Build Agent" -d /srv/tcagent tcagent # passwd tcagent # su - tcagent $ umask 022 $ mkdir .ssh $ vi .ssh/authorized_keys
Teamcity
From the Teamcity web UI run the agent push wizard (see the log below) to install the agent software.
Init
Setup the teamcity agent to run when the machine is restarted.
Create a systemd service file '/lib/systemd/system/teamcity-agent.service'.
[Unit] Description=TeamCity Build Agent After=network.target [Service] Type=forking EnvironmentFile=/etc/sysconfig/teamcity-agent PIDFile=/var/lock/subsys/teamcity-agent.pid ExecStart=/srv/tcagent/BuildAgent/bin/agent.sh start ExecStop=/srv/tcagent/BuildAgent/bin/agent.sh stop User=tcagent [Install] WantedBy=multi-user.target
Create a configuration file (this can be used to set JVM parameters)
# touch /etc/sysconfig/teamcity-agent # systemctl enable teamcity-agent
