1. 先启动nginx容器，把nginx的配置文件考出来

    cd /mydata
    docker run -p 80:80 —name nginx -d nginx:1.10
    docker container cp nginx:/etc/nginx . //注意nginx后面有个点
    docker stop nginx
    docker rm nginx
    mv nginx conf
    mkdir nginx
    mv conf nginx/
    mkdir -p /mydata/nginx/html
    mkdir -p /mydata/nginx/logs
