To set up Jenkins to run on multiple nodes, follow these steps:
1. Install the Jenkins master node on a server.
2. Install the Jenkins slave nodes on the other servers.
3. Configure the Jenkins master node to allow remote access.
4. Configure the Jenkins slave nodes to connect to the Jenkins master.
5. Create a Jenkins job to run on the Jenkins master node.
6. Configure the Jenkins job to run on multiple nodes.
7. Create a Jenkins build pipeline to run the job on the multiple nodes.
8. Run the Jenkins job and monitor the build.
For example, if you have two nodes, Node A and Node B, then you can configure the Jenkins job to run on both nodes. You can also configure the Jenkins build pipeline to run the job on both nodes in sequence. This will allow the job to run on both nodes in parallel, and will ensure that the job is completed faster.
