Adding Multiple Agents in TeamCity

Adding Multiple TeamCity agents running on the same server.

By default, when you install TeamCity, it gives you the option to install a Server and an Agent.

To add more agents:-

Login into the Server running TeamCity (TC) and open TC UI in the browser. Click on the Agents Tab

On the right hand side, Click on Install Build Agents > MS Windows Installer

Run the Agent Installer, Choose the directory where you want to install the agent (configuration)

** Make Sure this is a seperate directory from the previously installed agent.

Finally, in the agent configuration section –

> Edit the ownPort – Should not conflict with the already running agent’s port.

> Edit the serverUrl – Should point to the TC server URL

Click on Save.

IMP: When the pop-up comes, do not click on OK!

Open the Explorer and go to the \launcher\conf path in the Agent installation directory you configured above.

Each Agent is registered as a windows NT service and should have a unique name, otherwise, only one agent will connect at a time.

Open wrapper.conf and scroll till the end to the Wrapper Windows NT/2000/XP Service Properties

Change the properties highlighted below!

Now you can go back to the pop-up and click OK.

Continue with the rest of the installation process, and the Agent should be installed as a seperate service and visible under TeamCity UI.

Cheers!
