使用docker安装部署nginx

### 1.拉取镜像  ###

> docker pull nginx

### 2.创建挂载目录 ###

> mkdir -p /docker/data/nginx/\{conf,conf.d,html,logs\}

### 3.编写Nginx配置文件 ###

> cd /docker/data/nginx/conf
> 
> vim nginx.conf

需要在host文件配置：120.79.251.42   ecs.mayikt.com（这里120.79.251.42是虚拟机的IP地址）

#user  nobody;
    worker_processes  1;
    
    #error_log  logs/error.log;
    #error_log  logs/error.log  notice;
    #error_log  logs/error.log  info;
    
    #pid        logs/nginx.pid;
    
    
    events {
        worker_connections  1024;
    }
    
    
    http {
        include       mime.types;
        default_type  application/octet-stream;
    
        #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
        #                  '$status $body_bytes_sent "$http_referer" '
        #                  '"$http_user_agent" "$http_x_forwarded_for"';
    
        #access_log  logs/access.log  main;
    
        sendfile        on;
        #tcp_nopush     on;
    
        #keepalive_timeout  0;
        keepalive_timeout  65;
    
        #gzip  on;
    	### 上有服务器集群，默认轮训
        upstream  backServer {
    	    server 120.79.251.42:8080;
    		server 120.79.251.42:8081;
    	}
    	
        server {
            listen       80;
            server_name  ecs.mayikt.com;
    		
            location / {
    		    ### 指定上游服务器负载均衡服务器
    		    proxy_pass http://backServer/;
                index  index.html index.htm;
            }
        }
    
    }

### 4.启动容器 ###

> docker run -d --name nginx --restart=always -p 80:80 -v /docker/data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /docker/data/nginx/logs:/var/log/nginx docker.io/nginx

### 5.浏览器访问 ###

[http://120.79.251.42/][http_120.79.251.42]

此时负载均衡效果实现了

### 附加：进入容器内部，查看容器内部配置文件 ###

这里 e0fb5da9c9d3 是nginx的容器id

> docker container exec -it e0fb5da9c9d3 /bin/bash

配置文件以及挂载到容器内部的etc/nginx的配置文件中

如果外部挂载目录的配置文件修改，重启nginx容器即可（e0fb5da9c9d3为容器id）

> docker restart e0fb5da9c9d3
