首先安装git拉取我们的代码

1
yum update -y && yum install -y git

然后安装nginx

安装Nginx

安装nodeJS

下载安装包

1
wget https://nodejs.org/dist/v12.16.0/node-v12.16.0-linux-x64.tar.xz

解压

1
tar -xvf node-v12.16.0-linux-x64.tar.xz

修改配置文件etc/profile PATH=/opt/nodejs/bin:$PATH

**#你的node下载解压到路径 比如我刚刚解压到了 /opt/node/node-v12.16.0-linux-x64 那路径就是 PATH=/opt/node/node-v12.16.0-linux-x64/bin:$PATH**

echo "**PATH=/opt/node/node-v12.16.0-linux-x64/bin:$PATH**" >>/etc/profile

#刷新环境变量
source /etc/profile

#成功打印
[root@VM-4-3-centos bin]# node -v
v12.16.0

安装pm2

npm install pm2 -g

# 查看PM2版本
[root@VM-4-3-centos node-v12.16.0-linux-x64]# pm2 -v
5.1.2

安装完成之后准备三个文件

webhook.js 监听webhook 请求,这个请求是由GitHub配置webhook 请求我们的nginx,并且由nginx转发给我们

var http = require('http')
var createHandler = require('github-webhook-handler')
// path 是由nginx反向代理指定给我们的   nginx配置如下
// 监听webhook请求
//        location /onpush {
//                proxy_pass http://127.0.0.1:15535/onpush;

// secret 是github上设置的 加密字符
var handler = createHandler({ path: '/onpush', secret: 'XmkzRV8gHgzv33-' })

function run_cmd(cmd, args, callback) {
  var spawn = require('child_process').spawn;
  var child = spawn(cmd, args);
  var resp = "";

  child.stdout.on('data', function (buffer) { resp += buffer.toString(); });
  child.stderr.on('data', function (data) {
    console.log('stderr: ' + data);
  });
  child.stdout.on('end', function () { callback(resp) });
}

http.createServer(function (req, res) {

  handler(req, res, function (err) {
    res.statusCode = 404
    res.end('no such location')
  })
}).listen(15535, () => { // 监听的端口,对应我们的nginx反向代理的端口
  console.log('WebHooks Listern at 15535');
})
handler.on('push', function (event) {
  console.log('Received a push event for %s to %s',
    event.payload.repository.name,
    event.payload.ref);
  // 判断是否为 main分支，也可以自行修改
  if (event.payload.ref === 'refs/heads/master') {
    console.log('deploy master..')
    run_cmd('sh', ['./deploy.sh'], function (text) { console.log(text) });
  }
})

    "child-process": "^1.0.2",
    "github-webhook-handler": "^1.0.0",

执行拉去代码的shell脚本

# 进入部署上线项目的文件夹
cd /www/ryder.pw/fuguiliu.github.io;
# 进行拉取操作
git pull --rebase origin master;
# 如必要还需让项目重启
# 我是采用pm2 restart some_id的方式

再package.json 路径下初始化环境

1
npm i

最后再本地push一下你的代码
