Jenkins是开源CI&CD软件领导者， 支持构建、部署、自动化的插件超过1000个， 满足任何项目的需要

系统要求

• 最低推荐配置:

   256MB可用内存   1GB可用磁盘空间(作为一个Docker容器运行jenkins的话推荐10GB) 

• 小团队推荐的硬件配置：

   1GB 可用内存   50 GB  磁盘空间可用 

• 软件配置:

   Java 8：—无论是Java运行时环境（JRE）还是Java开发工具包（JDK）都可以。 

  • 2.164 (2019-02) 更新版本:Java 8 或 Java 11
  • 2.54 (2017-04) 和更新版：Java 8
  • 1.612 (2015-05) 和更新版：Java 7 我们下载jenkins>2.164, java使用java11，PC系统Ubuntu20.04

• 下载地址：

   https://www.oracle.com/java/technologies/javase/jdk11-archive-downloads.html 

  需要登录oracle 账号

• 配置java环境变量 下载后解压， 然后配置java到系统环境变量中，添加下面到~/.bashrc中

export JAVA_VERSION="jdk-11.0.13" export JAVA_HOME="${HOME}/Software/${JAVA_VERSION}" export JRE_HOME="${JAVA_HOME}/jre" export CLASSSPATH="${JAVA_HOME}/lib:${JRE_HOME}/lib" export PATH="${JAVA_HOME}/bin:${PATH}" 

检查配置是否有效

user@pc:~$ source ~/.bashrc user@pc:~$ java --version java 11.0.13 2021-10-19 LTS Java(TM) SE Runtime Environment 18.9 (build 11.0.13 10-LTS-370) Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.13 10-LTS-370, mixed mode) 

• 下载地址：

   https://www.jenkins.io/download/ 

下载lts版本war包：

• 配置java环境变量 配置jenkins将以下添加到系统环境变量中~/.bashrc中

export JENKINS_HOME="${HOME}/ci/jenkins_master" 

将jenkins.war放到JENKINS_HOME目录中

user@pc:~$  ls ci/jenkins_master/jenkins.war ci/jenkins_master/jenkins.war 

启动命令

• 前台启动命令：java -jar jenkins.war
• 后台启动命令：nohup java -jar jenkins.war &
