1、先安装nginx
docker pull nginx
2、创建目录
mkdir -p /Users/benjie/software/nginx/conf
mkdir -p /Users/benjie/software/nginx/logs
mkdir -p /Users/benjie/software/nginx/html
3、启动nginx 实例，为了复制配置
docker run --name nginx -p 80:80 -d nginx:latest
4、将容器内的配置文件拷贝到当前目录
docker cp nginx:/etc/nginx/nginx.conf /Users/benjie/software/nginx/conf/nginx.conf
docker cp nginx:/etc/nginx/conf.d /Users/benjie/software/nginx/conf/conf.d
docker cp nginx:/usr/share/nginx/html /Users/benjie/software/nginx/
5、终止原容器：docker stop nginx执行命令删除原容器：docker rm $ContainerId
6、创建新的 nginx；执行以下命令
docker run -p 80:80 --name nginx \
-v /Users/benjie/software/nginx/html:/usr/share/nginx/html \
-v /Users/benjie/software/nginx/logs:/var/log/nginx \
-v /Users/benjie/software/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
-v /Users/benjie/software/nginx/conf/conf.d:/etc/nginx/conf.d \
-d nginx:latest
