1. What is jenkins and what it does:
Jenkins is a scalable continuous integration (CI) platform. It's just a platform that really works with plugins.
The main roles of Jenkins:
Continuous monitoring of software version releases/test projects.
Monitors the work performed by external scheduled calls.
2. Download address: https://jenkins.io/download/ Current version: 2.211
The jenkins project has two release lines, namely LTS long-term support (or stable version) and weekly update version (latest version). It is recommended to choose LTS Long-term Support Edition and download the universal Java Project war package.
3. Download jdk version 1.8 or above and install it, and configure the environment variables of JDK after installation. (The specific steps will not be repeated here)
4. Run the command on the dos command line to extract the war package: java -jar jenkins.war (by default the port is 8080, if you want to use another port to start, you can modify it by using the command line "java –jar Jenkins.war --httpPort=80")
After running the command, jenkins.war will automatically generate a jenkins folder in the C disk directory. This folder under the C drive can be run independently.
