Nginx 入门（NGINX入门）

Nginx 简介#

Nginx 是一个非常流行的web服务器，可以用来作反向代理服务，负载均衡

安装Nginx#

Ubuntu默认提供了nginx的仓库，我们可以直接安装，安装之前更新包

sudo apt-get update
sudo apt-get install nginx

检查服务状态#

当我们安装完成之后，默认系统会启动nginx服务，我们可以通过如下命令检测服务运行状态

systemctl status nginx
● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
   Active: active (running) since Tue 2018-12-11 06:17:00 UTC; 15min ago
 Main PID: 4492 (nginx)
    Tasks: 3
   Memory: 5.4M
      CPU: 105ms
   CGroup: /system.slice/nginx.service
           ├─4492 nginx: master process /usr/sbin/nginx -g daemon on; master_process on
           ├─4496 nginx: worker process
           └─4497 nginx: worker process

管理Nginx服务#

sudo systemctl stop nginx        //停止nginx服务
sudo systemctl start nginx       //启动nginx服务
sudo systemctl restart nginx     //重启nginx服务
sudo systemctl reload nginx      //在不断掉连接的情况下重载配置
sudo systemctl enable nginx      //系统重启时，自动加载服务
