一、安装

进入 Jenkins官网，选择下载war，或者mac可以使用命令 brew install jenkins

任一选择一个版本

二、启动Jenkins服务

默认8080端口很大概率被占用，所以我直接配置了端口

// war包启动方式
java -jar jenkins.war —-httpPort=1100

// homebrew启动方式
brew services start jenkins —-httpPort=1100

若出现以下日志，是端口被占用的情况：

hudson.WebAppMain#contextDestroyed: Shutting down a Jenkins instance that was still starting up
Caused by: java.net.BindException: Address already in use
Caused: java.io.IOException: Failed to bind to 0.0.0.0/0.0.0.0:8080
Caused: java.io.IOException: Failed to start Jetty

若出现以下日志，则启动成功：
