02. docker安装 nginx

启动的时候也可以不带版本号直接拉取latest版

1.安装nginx

docker run -p 80:80 --name nginx \
 -v /usr/local/docker/nginx/conf:/etc/nginx  \
-v /usr/local/docker/nginx/html:/usr/share/nginx/html \
-v /usr/local/docker/nginx/conf.d:/etc/nginx/conf.d \
-v /usr/local/docker/nginx/logs:/var/log/nginx -d --restart=always nginx:1.19.0

   这样会-v：not found 

  需要创建挂载数据 -v 后路径的文件夹

mkdir /usr/local/docker/nginx/conf
mkdir /usr/local/docker/nginx/html
mkdir /usr/local/docker/nginx/conf.d
mkdir /usr/local/docker/nginx/logs

 

 把docker 容器中nginx的配置文件复制到宿主机

docker cp nginx:/etc/nginx /usr/local/docker/nginx/conf

重新运行nginx

docker stop nginx
docker rm nginx

docker run -p 80:80 --name nginx \
 -v /usr/local/docker/nginx/conf:/etc/nginx  \
-v /usr/local/docker/nginx/html:/usr/share/nginx/html \
-v /usr/local/docker/nginx/conf.d:/etc/nginx/conf.d \
-v /usr/local/docker/nginx/logs:/var/log/nginx -d --restart=always nginx:1.19.0

修改/usr/local/docker/nginx/conf/nginx.conf文件

user  nginx;
worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  65;
    
   server {      
        client_max_body_size 100M;
        listen       80;
        server_name  *.doson.com;

        if ($http_host ~* "^(.*?)\.doson\.com$") {    #正则表达式
                set $domain $1;                     #设置变量
        }

        location / {
            if ($domain ~* "mysql") {
             #  proxy_pass http://doson.com:3306;      #域名中有mysql，转发到3306端口
	 proxy_pass http://172.20.10.11:3306; 
            }
            if ($domain ~* redis{
             #  proxy_pass http://ds.com:6379;      #域名中有redis，转发到6379端口
	  proxy_pass http://172.20.10.11:6379; 
            }

            tcp_nodelay     on;
            proxy_set_header Host            $host;
            proxy_set_header X-Real-IP       $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            #以上三行，目的是将代理服务器收到的用户的信息传到真实服务器上
            
            root   html;
            index  index.html index.htm;            #默认情况
        }
   }
  
}

 修改C:\Windows\System32\drivers\etc下hosts文件，通过域名访问虚拟机

 

 说明nginx已成功启动
