一、需求说明
我有一个linux服务器，服务器上启动了docker，我有两个docker容器分别是两个web服务，分别是xx和yy：
# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 94d0294286f8 xx "catalina.sh run" 19 hours ago Up 19 hours 0.0.0.0:8088->8088/tcp xx 359d06deb64c yy "catalina.sh run" 12 days ago Up 12 days 0.0.0.0:8080->8080/tcp yy
我有两个域名:www.xx.com和www.yy.com,分别通过nginx映射到xx容器和yy容器上，其中
xx容器映射的port是:8088
yy容器映射的port是:8080
我想,在同一台服务上处理两个域名的反向代理:
1.浏览器输入www.xx.com的时候，nginx转发到xx容器上处理web请求
2.浏览器输入www.yy.com的时候，nginx转发到yy容器上处理web请求
二、Nginx安装
1.docker搜索

选择第一个即可
2.nginx配置
# mkdir -p /opt/docker/nginx/{conf.d,logs} # touch /opt/docker/nginx/nginx.conf
nginx.conf: nginx的默认配置
logs: nginx日志目录
conf: 自定义的配置文件目录
配置nginx.conf(重点)
events { worker_connections 1024; } http { server { listen 80; server_name xx.com; include /etc/nginx/conf.d/*.conf; location / { proxy_pass http://docker-ip:8088; } } server { listen 80; server_name yy.com; include /etc/nginx/conf.d/*.conf; location / { proxy_pass http://docker-ip:8080; } } }
3.执行安装
# docker run --name nginx -p 80:80
-v /opt/docker/nginx/nginx.conf:/etc/nginx/nginx.conf
-v /opt/docker/nginx/conf.d:/etc/nginx/conf.d
-v /opt/docker/nginx/logs:/var/log/nginx
-d nginx

三、说明
1.验证效果是，浏览器中输入www.xx.com时跳转到xx的docker容器处理web请求，当浏览器输入www.yy.com的时候，跳转到yy的docker容器处理web请求
2.我在一个坑里爬了很长时间，原因是很多资料不是docker的，所以配置的都是localhost，当nginx为docker容器的时候，localhost域名跳转不到xx和yy容器，必须通过docker的ip进行跳转到xx和yy容器
