docker nginx 反向代理

上一篇介绍了docker 安装和docker-compose配置

使用docker pull nginx:1.12.0

编写docker-compose.yml

nginx:
image: 17daebd00e2c
ports:
- 80:80
volumes:
- /home/conf/nginx.conf:/etc/nginx/nginx.conf
links:
- nginx1
- nginx2
privileged: true

nginx1:
image: 17daebd00e2c
volumes:
- /home/www1:/usr/share/nginx/html
privileged: true

nginx2:
image: 17daebd00e2c
volumes:
- /home/www2:/usr/share/nginx/html
privileged: true

编写nginx.conf

在http模块中添加

upstream pro {
ip_hash;//根据ip访问,测试时可以注释
server nginx1:80;
server nginx2:80;
}

server模块中添加

location / {
proxy_pass http://pro;
#proxy_redirect off;
#如果是非80端口，配置为Host $host：端口号，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
proxy_set_header Host $host;
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 128k;
proxy_connect_timeout 300;
proxy_send_timeout 300;
proxy_read_timeout 300;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
add_header Access-Control-Allow-Origin *;

}

最后在www1和www2目录中添加html文件

直接访问html地址即可

nginx1和nginx2只可以在docker容器中访问
