Docker部署nginx访问宿主机图片文件

1、首先先用docker拉取nginx镜像

docker pull nginx

2、运行nginx，可以指定别名

docker run --name nginx -d nginx

3、复制容器内部的配置文件到宿主机，不用事先创建映射目录

docker cp -a nginx:/etc/nginx/ /mydata/nginx

4、强制关闭删除

docker rm -f nginx

5、修改mydata/nginx里面的nginx.conf文件（不赞成）或在其他目录下创建nginx.conf文件（推荐），conf内容如下

user root;
worker_processes 1;
 
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;
 
events {
	worker_connections 1024;
}
 
http {
	include       /etc/nginx/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  /var/log/nginx/access.log  main;
	
	sendfile on;
 
	keepalive_timeout 65;
	
	include /etc/nginx/conf.d/*.conf;
 
}

6、在nginx.conf同样位置创建nginx-file-server.conf文件，内容如下

server {
		listen 80;
		server_name localhost;
	 
		charset utf-8; # 避免中文乱码
 
		location ~* .(gif|jpg|jpeg|png|css|js|ico|cur|eot|ttf|woff2|svg|woff|pdf|doc|docx|xls|xlsx|txt|json|otf|csv)$ {
			expires 24h;
			root /data/;#指定图片存放路径
			proxy_store on;
			proxy_store_access user:rw group:rw all:rw;
			proxy_temp_path /datat/;#图片路径
			proxy_redirect off;
			 
			proxy_set_header Host 127.0.0.1;
			proxy_set_header X-Real-IP $remote_addr;
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			client_max_body_size 10m;
			client_body_buffer_size 1280k;
			proxy_connect_timeout 900;
			proxy_send_timeout 900;
			proxy_read_timeout 900;
			proxy_buffer_size 40k;
			proxy_buffers 40 320k;
			proxy_busy_buffers_size 640k;
			proxy_temp_file_write_size 640k;
			#if ( !-e $request_filename)
			#{
			#	proxy_pass http://127.0.0.1:8000; #代理访问地址
			#}
		}
		
		location ~* .(htm|html)$ {
			add_header Cache-Control no-store;
			add_header Pragma no-cache;
			root /data/html/;
		}
	 
		location / {
			root html;
			index index.html index.htm;
		}
	 
 
		error_page 500 502 503 504 /50x.html;
		location = /50x.html {
			root html;
		}
 
	}

7、运行nginx容器，指令如下

docker run -d -p 10080:80 --name nginx -v /mydata/image:/data -v /mdata/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /mdata/nginx/conf/nginx-file-server.conf:/etc/nginx/conf.d/default.conf nginx

mydata/image是存放图片的位置

启动完用docker ps查看nginx是否启动成功

8、访问图片是否代理成功
