CICD项目发版脚本

本文主要介绍通过shell脚本完成线上发版，自动打发版tag，方便线上功能回退。结合Jenkins参数化构建，可以实现自动化发布。

## 分支名
tag_name='dev'
IN_TAG=$tag_name
## git地址
GIT_DIR='[email protected]:****/paas-service-web.git'
## 项目名
GIT_PROJ_NAME=$(echo $GIT_DIR|awk -F/ '$0=$NF'|awk -F\. '$0=$1')
## 工作目录
WORKSPACE='/home/darren/data'
## 发版用户
BUILD_USER='xiaozq'
## 线上服务器地址
HOST='192.144.172.239'
## 服务器部署目录
DEPLOY_DIR='/data/xiaoyaospace'

这些参数需要改成自己对应的参数，需要配置ssh免密钥登录

执行方式 sh -x paas_jenkins.sh 分支名

依赖环境

maven
git
jdk

源码
paas_jenkins.sh (接收的是jenkins传过来的参数，可以改成指定参数，直接运行)

#!/bin/bash

## 分支名

## git地址
GIT_DIR=$git
## 项目名
GIT_PROJ_NAME=$(echo $GIT_DIR|awk -F/ '$0=$NF'|awk -F\. '$0=$1')
## 工作目录
#WORKSPACE='/home/darren/data'
## 发版
BUILD_USER=$BUILD_USER_ID
## 线上服务器地址
HOST=$server_list
## 服务器部署目录
DEPLOY_DIR=$deploy_dir
## 使用端口号
SERVER_PORT=$server_port
## 检测项目启动地址
