安裝nodejs
sudo apt-get install nodejs
sudo apt install nodejs-legacy
sudo apt install npm
初始化
mkdir webservices
cd webservices
npm init
安裝express
sudo npm install express
創(chuàng)建app.js
var express = require("express")
var app = express();
app.get("/hello",function (req,resp) {
resp.send("hello express!");
});
app.listen(80,function () {
console.log("server start!!");
});
啟動(dòng)服務(wù)
# 啟動(dòng)服務(wù)
node app.js
# 后臺(tái)啟動(dòng)服務(wù)
nohup node app.js &
到此為止尚骄，已經(jīng)成功的創(chuàng)建了一個(gè)http的服務(wù)器，并且提供了RESTful Api侵续。
安裝ssl證書倔丈，https訪問
安裝certbot
https://certbot.eff.org/lets-encrypt/ubuntuxenial-other
$ sudo apt-get update
$ sudo apt-get install software-properties-common
$ sudo add-apt-repository universe
$ sudo add-apt-repository ppa:certbot/certbot
$ sudo apt-get update
$ sudo apt-get install certbot
生成證書
$ sudo certbot certonly --standalone -d example.com
之后就會(huì)生成下面幾個(gè)文件憨闰，具體位置會(huì)有提示
cert.pem
chain.pem
fullchain.pem
privkey.pem
修改app.js
