Start TeamCity Agent
When the newly installed agent connects to the server for the first time, it appears on the Agents | Unauthorized agents page visible to administrators/users with the permissions to authorize it. Agents will not run builds until they are authorized in the TeamCity UI. The agent running on the same computer as the server is authorized by default.
The number of authorized agents is limited by the number of agent licenses on the server. See more under Licensing Policy.
TeamCity build agents can be started manually or configured to start automatically.
Run the following script:
<installation path>\bin\agent.bat start
on Linux and macOS:
<installation path>\bin\agent.sh start
Automatic Agent Start Under Windows
To run an agent automatically on a Windows machine launch, you can either set up the agent to run as a Windows service or use another method. Using the Windows service approach is the easiest way, but Windows applies some constraints to the processes run this way.
A TeamCity agent works reliably under a Windows service provided all the requirements are met, but it is often not the case for the build processes configured to be run on the agent. This is why it is recommended running a TeamCity agent as a Windows service only if all your build scripts support this. Otherwise, it is advised to use alternative OS-specific methods to start a TeamCity agent automatically.
One of them is to configure an automatic user logon on Windows start and then configure the TeamCity agent start (via
agent.bat start) on the user logon (for example, via Windows Task Scheduler).
Build Agent as Windows Service
On Windows, you may want to launch a TeamCity agent as a service to allow running it without any user logged in. If you use the Windows agent installer, you have an option to install the service in the installation wizard.
The following instructions can be used to install a Windows service manually (for example, after
.zip agent installation). This procedure should also be performed to create Windows services for the second and following agents on the same machine.
Install the service:
Check if the service with the required name and ID (see Step 4; the service name is TeamCity Build Agent by default) is not present. If installed, remove it.
Check that the
wrapper.java.commandproperty in the
<agent home>\launcher\conf\wrapper.conffile contains a valid path to the Java executable in the JDK installation directory. You can use
wrapper.java.command=../jre/bin/javafor the agent installed from the Windows distribution file. Make sure to specify the path of the
java.exefile without any quotes.
If you want to run the agent under a user account (recommended) and not "System", add the
wrapper.ntservice.passwordproperties to the
<agent home>\launcher\conf\wrapper.conffile with appropriate credentials.
(for the second and following agents on the same machine) Modify the
<agent>\launcher\conf\wrapper.conffile so that the
wrapper.ntservice.descriptionproperties have unique values within the OS.
<agent home>\bin\service.install.batscript under a user with sufficient privileges to register a new agent service. Make sure to start the agent for the first time only after it is configured as described.
Start the service:
<agent home>/bin/service.start.bat(or use the standard Windows Services applet).
Stop the service:
<agent home>/bin/service.stop.bat(or use the standard Windows Services applet).
You can also use the standard Windows
net.exe utility to manage the service once it is installed. For example (assuming the default service name):
<agent home>\launcher\conf\wrapper.conf file can also be used to alter the agent JVM parameters.
Note that the user account used to run the build agent service must have enough rights to start/stop the agent service.
Automatic Agent Start Under Linux
To run an agent automatically on a Linux machine launch, configure a daemon process with the
agent.sh start command to start it and the
agent.sh stop command to stop it.
systemd, see the example
teamcityagent.service configuration file:
init.d, refer to this example procedure:
Navigate to the services` scripts directory:cd /etc/init.d/
Open the build agent service script:sudo vim buildAgent
Paste the following content into the file:#!/bin/sh ### BEGIN INIT INFO # Provides: TeamCity Build Agent # Required-Start: $remote_fs $syslog # Required-Stop: $remote_fs $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Start build agent daemon at boot time # Description: Enable service provided by daemon. ### END INIT INFO #Provide the correct user name: USER="agentuser" case "$1" in start) su - $USER -c "cd BuildAgent/bin ; ./agent.sh start" ;; stop) su - $USER -c "cd BuildAgent/bin ; ./agent.sh stop" ;; *) echo "usage start/stop" exit 1 ;; esac exit 0
Set the permissions to execute the file:sudo chmod 755 buildAgent
Make links to start the agent service on the machine boot and on restarts using the appropriate tool:
For Debian/Ubuntu:sudo update-rc.d buildAgent defaults
For Red Hat/CentOS:sudo chkconfig buildAgent on
Automatic Agent Start Under macOS
For macOS, TeamCity provides the ability to load a build agent automatically when a build user logs in.
The recommended approach is to use
To configure an automatic build agent startup via
launchd, follow these steps:
Install a build agent on via
conf/buildAgent.propertiesfile (set at least the agent name).
Make sure that all files under the
buildAgentdirectory are owned by
your_build_userto ensure a proper agent upgrade process.
Load the build agent via the command:mkdir buildAgent/logs # Directory should be created under your_build_user user sh buildAgent/bin/mac.launchd.sh load
Run these commands under the
your_build_useraccount. Wait up to several minutes for the build agent to autoupgrade from the TeamCity server. You can watch the process in the logs:tail -f buildAgent/logs/teamcity-agent.log
When the build agent upgrades and successfully connects to the TeamCity server, stop the agent:sh buildAgent/bin/mac.launchd.sh unload
After the build agent upgrades from the TeamCity server, copy the
buildAgent/bin/jetbrains.teamcity.BuildAgent.plistfile to the
$HOME/Library/LaunchAgents/directory (you might have to create it). If you do not want TeamCity to start under the root permissions, specify the
UserNamekey in the
.plistfile, for example:<key>UserName</key> <string>your_build_user</string>
Configure your macOS system to automatically log in as
your_build_user, as described here.
Restart the machine. On the system startup, the build user should automatically log in, and the build agent should start.
To quickly check that the build agent is running, use the following command:launchctl list | grep BuildAgent 69722 0 jetbrains.teamcity.BuildAgent
Stop Build Agent
To stop the agent manually, run the
<Agent home>\agent script with the
stop to request stopping after the current build finished. Use
stop force to request an immediate stop (if a build is running on the agent, it will be stopped abruptly (canceled)).
Under Linux, you can also use
stop kill to kill the agent process.
If the agent runs with a console attached, you may also press
Ctrl+C in the console to stop the agent (if a build is running, it will be canceled).
If a build agent has been started as a
LaunchAgent service on macOS, it can be stopped using the
