Jenkins Learning Task 10 - How to add Slave Nodes in Jenkins

How to add Slave Nodes/SSH build agents in Jenkins

1. Add Git server(mnode01) and App server(mnode02) as SSH build agent/slave nodes in Jenkins. The slave nodes name must be Git_mnode01, App_mnode02 respectively.

2. Add labels as below

    Git_mnode01: mnode01

    App_mnode02 : mnode02

3. Remote root directory for Git_mnode01  must be /home/kumar/jenkins and App_mnode02 must be /home/john/Jenkins 

4. Make sure slave nodes are online and working properly.

Pre-Requisite

* This Task based on the Learning LAB, which I have set up with 3 servers.

mnode01 is my git server, mnode02 is my app server and master is my Jenkins server.

* Should have ssh connection between servers.

* You might need to install some plugins and restart Jenkins service. 

Solution

Step 1: Install Java on all Node servers ( app, git servers)

Step 2: Install SSH build agent plugin in Jenkins,

Step 4: Setup the slave nodes in jenkins.

Verification:

    Refresh the nodes list. You should see the newly added nodes with the system statistics details.

Check below the sample solution video for the above task.

Jenkins Learning Task 09 - Schedule a job in Jenkins

 Schedule a job in Jenkins

1. Create a Jenkins job named logs-copy.

2. Configure it to periodically build every 5 minutes to copy the Apache logs (both access_log and error_logs) from mnode02 (from default logs location) to location /data on mnode01 Server.

Note: * This is a learning task and you can try to do it in your own learning environment. I have done a sample solution using VirtualBox with Ubuntu OS.

Pre-Requisite

* This Task based on the LAB which I have set up with 3 servers.

mnode02 is my app server mnode01 is my git server and master is my jenkins server

* Should have ssh connection between servers.

* You might need to install some plugins and restart Jenkins service. 

Solution

Step 1: Enable password-less sudo in-app server and git server

Step 2: Enable password-less SCP 

Step 3: Install SSH Plugins in Jenkins

Step 4: Setup Credentials for SSH users

Step 5: Add SSH Hosts in Jenkins

Step 6: Create a Scheduled Build Job

Verification:

ssh to  mnode01  server and got to /data dir and check the logs are available.

Check below the sample solution video for the above task.
