云效部署实现Java项目自动化部署图解

前言

记录下使用云效部署Java项目，实现java项目一键化自动化部署。

云效流程说明：

1.云效拉取最新git代码后

2.进行maven编译打包后，上传到指定服务器目录

3.通过shell脚本，先kill java项目后，通过java -jar 启动项目。

操作步骤

注：git代码更新需要手动更新

添加服务连接-获得阿里云授权

部署脚本配置：

# 创建必要的目录
mkdir -p /usr/local/nginx/app
mkdir -p /usr/local/nginx/app/mall-im_turn_java
mkdir -p /usr/local/nginx/app/mall-im_turn_java/jar

mkdir -p /usr/local/nginx/app/mall-im_turn_java/jar/logs
# 解压文件
tar zxvf /usr/local/nginx/app/mall-im_turn_java/mall_release.tgz -C /usr/local/nginx/app/mall-im_turn_java/jar
# 执行sh脚本
cd /usr/local/nginx/app/mall-im_turn_java/jar
bash /usr/local/nginx/app/mall-im_turn_java/jar/start_run.sh

#进入此目录

cd /usr/local/nginx/app/mall-im_turn_java/jar

#编辑java启动脚本不同jar包名称-按这个替换即可 mall-im-1.0-SNAPSHOT.jar

vi start_run.sh
