Jenkins 安装教程

环境

  • CentOS 7.6 64位
  • JDK version 17.0.5
  • Jenkins version 2.361-1.1.noarch

安装JDK

  1. 创建安装文件夹：mkdir /usr/local/java

  2. 把 JDK 安装包解压到该文件夹：tar -zxvf /root/jdk-17_linux-x64_bin.tar.gz -C /usr/local/java

  3. 配置环境变量，在 /etc/profile ⽂件中加入jdk路径即可：

1

4
JAVA_HOME=/usr/local/java/jdk-17.0.5
CLASSPATH=$JAVA_HOME/lib/
PATH=$PATH:$JAVA_HOME/bin
export PATH JAVA_HOME CLASSPATH
  1. 执行：source /etc/profile

安装 Jenkins

  1. yum install /root/jenkins-2.361-1.1.noarch.rpm

  2. 给 Jenkins 配置JDK，以及修改端口

    1. vim /usr/lib/systemd/system/jenkins.service

    2. service jenkins start

配置 Jenkins

  • 浏览器访问 Jenkins：http://ip地址:端口。第一次访问需要输入初始密码，按页面上展示操作就行（没截到图）。

  • Jenkins 默认地址下载很慢，这里选自定义安装

  • 选“无”

  • 然后该填填，一路默认就好

插件安装和配置

插件安装页面 ：Dashboard > Manage Jenkins > Manage Plugins

修改插件地址

service jenkins start

cd /var/lib/jenkins/updates

sed -i 's/http:\/\/updates.jenkinsci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json && sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' default.json

安装和配置 Gitee 插件

因为我忘记截图，这里就直接用之前写好图文了，都差不多的。

插件安装之后，打开“系统管理” —> “系统设置”，找到Gitee 配置，配置如下：

配置 Git

解决办法：

  1. 修改 /usr/lib/systemd/system/jenkins.service 文件，找到被注释的 Environment="JAVA_HOME="，把自己的java路径填上去。
  2. systemctl daemon-reload
