TeamCity BuildAgent Installations

Download Zipfile

We need to download a zip file from the teamcity server to install it on the agent. Replace the server-url with your server ip or server hostname.

mkdir /opt/teamcity

wget http://server-ip:8111/update/buildAgent.zip

sudo unzip buildAgent.zip
sudo chmod +x bin/agent.sh

vim buildAgent.dist.properties

serverUrl=http://server-ip:8111/
cp conf/buildAgent.dist.properties conf/buildAgent.properties

Start Service

# cd /opt/teamcity/buildAgent/bin

# ./agent.sh

You would need to authorize the agent in the buildserver once its get detected. you can now start your build and work along.
