Why use Jenkins distribution?

Using jenkins distributed to build job, when the amount of job is large enough, it can effectively relieve the pressure on jenkins-master, increase the number of parallel job, and reduce the time when job is in pending state.

Prepare:

Launch jenkins as master ip:192.168.29.94 on windows

Mac computer as slave ip:192.168.22.99

Deployment method:

Method 1: (recommended)

Jenkins ver2.155 is deployed by throwing war packets into tomcat. You can access the Jenkins address by starting tomcat: the advantage of http://localhost:xxx/jenkins, is that there is no root permission problem, and it is convenient and flexible to start and stop.

Method 2:

Start directly with .war package, and it is easy to report an error if you modify the configuration.

Unstable operation, add, modify plug-ins or permissions, easy to crash

It is not convenient to restart the Jenkins service, (java-jar / xx/xx/jenkins.war-- httpPort=xxxx)

Jenkins-master Settin

1. System Management-> manage Node-> New Node

Configuration introduction:

Name: take whatever you want. Slave-xx is recommended.

Number of concurrent components:

1. This value controls the number of Jenkins concurrent builds. Therefore, this value will affect the load pressure of the Jenkins system. Using the number of processors as its value would be a better choice.

two。 Increasing this value makes each build take longer to run, but it increases the overall number of builds because it allows CPU to build another project while it is waiting for IBO.

3. Setting this value to 0 is useful for removing a failed slave node from Jenkins without losing configuration information.

Remote working directory:

The directory of the slave machine. Jenkins uses JNLP to connect to remote slave.

Label:

Used to group multiple nodes

Usage:

Choose to use this node as much as possible, and priority will be given to building job on this node.

If you choose to bind only job, you need to specify the slave node in the running node.

Startup mode:

I choose to start the agent through java web here; you can use ssh

Other settings:

It's easy to understand. It's clear at a glance.

Just configure the Jenkins node. Next, create a directory on slave. I specified the directory on the mac machine: / Users/louiezhou/home/jenkins.

Start the slave node

Click on the newly created node and you will see a launch button that downloads a slave-agent.jnlp file and places it in the slave machine directory

Double-click to start.

Node list:

You can tell which is online and which is not at a glance.
