1.准备docker环境

参考 Centos安装Docker

2.拉取镜像

docker pull nginx:版本号

docker pull nginx:latest

3.运行容器

顺序执行以下命令

先开一个复制配置的容器

docker run -d --name nginx-cp -p 80:80 nginx

开始复制 docker cp 容器id|容器名称:复制的目录|文件 宿主机的目录|文件

docker cp nginx-cp:/etc/nginx/nginx.conf /usr/local/docker/nginx/conf/nginx.conf
docker cp nginx-cp:/etc/nginx/conf.d /usr/local/docker/nginx/conf/
docker cp nginx-cp:/usr/share/nginx/html /usr/local/docker/nginx/

删除测试容器

docker stop nginx-cp
docker rm nginx-cp

nginx运行并挂在目录

docker run -d --name nginx -p 80:80 --restart=always \
-v /usr/local/docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf \
-v /usr/local/docker/nginx/conf/conf.d:/etc/nginx/conf.d \
-v /usr/local/docker/nginx/html:/usr/share/nginx/html \
-v /usr/local/docker/nginx/log:/var/log/nginx \
nginx

# 参数解释

# 挂载配置文件
-v /usr/local/docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf 
-v /usr/local/docker/nginx/conf/conf.d:/etc/nginx/conf.d

# 挂载html
-v /usr/local/docker/nginx/html:/usr/share/nginx/html

# 挂载日志
-v /usr/local/docker/nginx/log:/var/log/nginx

4.查看nginx运行状态

docker logs 容器id|名称

docker logs nginx
