Linux安装jenkins

Linux环境：centos7.6

 摘要：部署jenkins方法很多。(1. rpm安装 2. war包安装 3. docker部署) 本文采用rpm方式安装

1. 华为云下载，注意与jdk版本对应(这里jdk1.8)。
https://repo.huaweicloud.com/jenkins/redhat-stable/jenkins-2.346.3-1.1.noarch.rpm

2. 安装
cd /usr/local/service
rpm -ivh jenkins-2.346.3-1.1.noarch.rpm

3. 修改配置文件与授权
vi /etc/syscofig/jenkins
JENKINS_USER ="root”
JENKINS_PORT="8888"
vi /etc/init.d/jenkins
/usr/local/service/jdk1.8.0_333/bin/java
# 授权
chmod 777 -R /var/lib/jenkins/
chmod 777 -R /var/cache/jenkins/
chmod 777 -R /var/log/jenkins/

4. 启动jenkins
cd /etc/init.d
./jenkins start
./jenkins stop
./jenkins restart
./jenkins status

5. 访问ip:8888,密码获取
cat /var/lib/jenkins/secrets/initialAdminPassword
# 安装推荐插件(熟悉了之后，自己可选择安装)

6. 修改服务器配置，将插件下载地址换成国内地址
# linux可直接运行下面命令
cd /var/lib/jenkins/updates
sed -i 's/https:\/\/updates.jenkins.io\/download/http:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json
sed -i 's/www.google.com/www.baidu.com/g' default.json
# vi /usr/lib/systemd/system/jenkins.service
Environment="JENKINS_PORT=8888"
# 刷新配置
systemctl daemon-reload

7. 进入 Manage Jenkins -》 Manage Plugin -> Advanced 最下面有 Update Site 设置为：http://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

8. 重启jenkins

9. 卸载jenkins
cd /etc/init.d
./jenkins stop
# rpm卸载
rpm -e jenkins
# 检查是否卸载成功
rpm -ql jenkins
# 彻底删除残留文件
find / -iname jenkins | xargs -n 1000 rm -rf
