CentOS使用docker安装nginx

1、docker pull nginx
2、简易启动：docker run -d --name nginx -p 18089:80 nginx
3、将容器nginx.conf文件、conf.d文件夹内容复制到宿主机conf下

docker cp nginx:/etc/nginx/nginx.conf /usr/local/docker/nginx/conf

docker cp nginx:/etc/nginx/conf.d /usr/local/docker/nginx/conf

4、停止并删除容器：docker stop nginx docker rm nginx
5、挂载方式启动：

docker run \
-p 18089:80 \
--name nginx \
--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/log:/var/log/nginx \
-v /usr/local/docker/nginx/html:/usr/share/nginx/html \
-d nginx

6、在/usr/local/docker/nginx/html创建图片文件夹img、并上传一个图片

配置conf.d下的default.conf文件，添加：

location /img {
       root    /usr/share/nginx/html;
       autoindex       on;
}

7、重启：docker restart nginx
8、开放端口并访问：http://47.xxx.xxx.xx:18089/img/10b9f2859c586dd2c24f35d5d3246c7.jpg
