1.pull nginx
docker pull nginx 2.安装docker
docker run --name nginx -p 80:80 -d nginx 3.虽然咱们能正常启动nginx，但配置得在容器中进行，这样的话太麻烦了，所以把配置文件给映射出来，方便配置与管理
mkdir -p /data/nginx
mkdir -p /data/nginx/www
mkdir -p /data/nginx/conf
mkdir -p /data/nginx/logs 4.将容器中的相应文件copy到刚创建的管理目录中
docker cp nginx:/etc/nginx/nginx.conf /opt/nginx/
docker cp nginx:/etc/nginx/conf.d /opt/nginx/conf/
docker cp nginx:/usr/share/nginx/html/ /opt/nginx/www/
docker cp nginx:/var/log/nginx/ /opt/nginx/logs/ 5.停止并移除容器
docker stop nginx
docker rm nginx 6.重新挂载
docker run --name nginx -p 80:80
-v /opt/nginx/nginx.conf:/etc/nginx/nginx.conf
-v /opt/nginx/www/:/usr/share/nginx/html/
-v /opt/nginx/logs/:/var/log/nginx/
-v /opt/nginx/conf/:/etc/nginx/conf.d
--privileged=true -d nginx
