docker run -p 80:80 -p 81:81 --name nginx -v /root/nginx/www/dvwa/:/usr/share/nginx/html/dvwa -v /root/nginx/conf.d:/etc/nginx/conf.d -v /root/nginx/www/xss:/usr/share/nginx/html/xss --link php:php --link mysql:mysql -d nginx:latest

方式一：修改配置文件（需停止docker服务）
1、停止docker服务
systemctl stop docker.service（关键，修改之前必须停止docker服务）
2、vim /var/lib/docker/containers/container-ID/config.v2.json
修改配置文件中的目录位置，然后保存退出

"MountPoints":{"/home":{"Source":"/docker","Destination":"/home","RW":true,"Name":"","Driver":"","Type":"bind","Propagation":"rprivate","Spec":{"Type":"bind","Source":"//docker/","Target":"/home"}}}

3、启动docker服务
