|NO.Z.00033|——————————|^^ 重要 ^^|——|CI/CD&Jenkins_pipeline操作.V07|——|Jenkins环境变量配置|插件下载_更换国内源|

一、Jenkins环境变量配置

### --- Jenkins插件maven安装——二进制
~~~     下载maven版本包

[root@jenkins ~]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.5.4/binaries/apache-maven-3.5.4-bin.tar.gz

### --- 安装maven版本包

[root@jenkins ~]# tar -zxvf apache-maven-3.5.4-bin.tar.gz -C /usr/local/
[root@jenkins ~]# cd /usr/local/
[root@jenkins local]# ln -s apache-maven-3.5.4/ maven

### --- 查看maven版本

[root@jenkins local]# mvn -version
Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-18T02:33:14+08:00)
Maven home: /usr/local/maven
Java version: 1.8.0_281, vendor: Oracle Corporation, runtime: /usr/local/jdk1.8/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-862.el7.x86_64", arch: "amd64", family: "unix"

二、配置JDK/Git/Maven

### --- 配置JDK/Git/Maven

~~~     ——>系统管理->全局工具配置
~~~     ——>jdk：可以自动安装，但是我们已经安装了，这里写入我们jdk的路径即可
~~~     ——>因为我们使用yum安装的maven，默认即可
~~~     ——>git:
~~~     ——>maven：

三、jenkins 下载插件失败处理办法

### --- jenkins 下载插件失败,提示：

java.io.IOException: Downloaded file /app/jenkins_home/plugins/jacoco.jpi.tmp does not match expected SHA-1, expected 'CtK02wHdFOxTutqhUQzmue6uvpg=', actual 'YGO05utKyaaFzpGCgCE95GS0WsU='

### --- 更换源中国源的问题。需要换个源就可，换源方法：

~~~     jenkins->系统管理->管理插件->高级
~~~     选择升级站点把：http://updates.jenkins-ci.org/update-center.json
~~~     # 换成：http://mirror.esuni.jp/jenkins/updates/update-center.json
~~~     镜像地址查询：http://mirrors.jenkins-ci.org/status.html
