如何部署Nodejs服务

Favori,

Deploy

服务器

阿里云 https://www.aliyun.com/daily-act/ecs/activity_selection

下载安装包

wget https://nodejs.org/dist/v10.9.0/node-v10.9.0-linux-x64.tar.xz

解压

tar xf  node-v10.9.0-linux-x64.tar.xz

设置软链接

ln -s /root/node-v10.9.0-linux-x64/bin/node   /usr/local/bin/node
ln -s /root/node-v10.9.0-linux-x64/bin/npm   /usr/local/bin/npm`

查看Node版本和npm版本

node -v
npm -v

设置npm源

npm config set registry  https://registry.npm.taobao.org

服务器安装pm2

npm install -g pm2
ln -s /root/node-v10.9.0-linux-x64/bin/pm2 /usr/local/bin/

配置ssh

  • 本地生成秘钥对: ssh-keygen -t rsa demo_id_rsa
  • 将公钥放到服务器上:
scp ~/.ssh/demo_id_rsa.pub root@39.107.238.161:/root/.ssh/authorized_keys
  • 修改ssh配置 vi ~/.ssh/config
Host john
HostName 39.107.238.161
User root
Port 22
IdentityFile ~/.ssh/demo_id_rsa
  • 服务器上修改ssh配置 vim /etc/ssh/sshd_config

PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys

  • 最后就可以ssh登录了! ssh john

将本地代码同步到服务器

rsync -avzp -e "ssh" ./Internet/ john:/root/app

服务器上启动http

pm2 start /root/app/http-server.js

本地修改发布命令

新建deploy.sh文件

#!/bin/bash
 
HOST=john
 
rsync -avzp -e "ssh" ./Internet/ $HOST:/root/app
ssh $HOST "pm2 restart /root/app/http-server.js"
 
echo 'deploy success'

初始化npm命令

npm init 新增scripts "deploy": "./deploy.sh"

发布

npm run deploy

修改http-server的监听host

const http = require('http')
const host = '0.0.0.0';
const port = 80;
http.createServer(function (req, res) {
    res.writeHead(## {
        'Content-Type': 'text/plain'
    })
    res.end('Hello World')
}).listen(port, host)
 
console.log(`Server running at http://${host}:${port}/`)

ECS安全组添加80端口

查看服务器上是否已正常监听80端口

netstat -tpln

通过ip+端口访问

39.107.238.161:80
