Jenkins

1.安装jenkins

从官网下载jenkins 2.32.3的rpm版本 jenkins

上传到服务中

# cd /opt
# rz -bey jenkins-2.32.3-1.1.noarch.rpm

安装jenkins

# rpm -Uvh rz -bey jenkins-2.32.3-1.1.noarch.rpm

2.配置jenkins

jenkins默认启动在8080端口,需要打开防火墙

# systemctl start firewalld.service
# firewall-cmd --zone=public --add-port=80/tcp --permanent
# firewall-cmd --reload

启动jenkins服务

# systemctl start jenkins

其它

## 查看服务
# systemctl status jenkins

## 停止服务
# systemctl stop jenkins

## 重启服务
# systemctl restart jenkins

3.配置部署环境

• 配置java环境
• 配置maven环境
• 配置Gradle环境

4. 配置部署脚本

api-deploy.sh

#!/bin/bash

Deploy

上传到服务器

# mkdir /opt/bin
# cd /opt/bin
# rz -bey api-deploy.sh

修改脚本执行权限
# chmod 777 api-deploy.sh

添加链接
# ln -s /opt/bin/api-deploy.sh /usr/bin/api-deploy

5.配置jenkins

Execute shell

cp -rf ${WORKSPACE}/build/libs/boot-api-1.0.0.jar /opt/deploy/
BUILD_ID=dontKillMe api-deploy --jar-name=boot-api-1.0.0.jar --webapp-path=/opt/deploy --server-port=80

注意:如果使用nohup命令后台运行程序,jenkins中必须使用BUILD_ID=dontKillMe
