centos7环境下nodejs环境的部署过程

1.yum安装nodejs环境
curl -sL https://rpm.nodesource.com/setup_12.x | bash -

yum install -y nodejs

2.安装pm2插件
npm install pm2 -g

3.发布脚本
$ cat /usr/local/worksh/jenkins_rsync/hw_yt_rsync_www.chinasoft.com.templates.sh
#!/bin/bash

##############公司jenkins拉取git代码同步到 publish 上，然后触发 publish 上的该脚本同步到web服务器####################
