mysql+nginx+docker+centos

掏了一台低廉的mysql云服务器（ecs同区同网），但是没有提供外网ip，希望在调测过程中，能够本地连接它。
那么，在ecs上部署nginx，内网连接mysql。

详见《Kubernetes（k8s）集群搭建》

• 1拉取镜像

docker pull nginx

• 2启动样本容器

docker run --name nginx-temp -d -p 80:80 --restart=always -e TZ="Asia/Shanghai" nginx:latest

• 3创建宿主目录，复制样本数据

mkdir /usr/local/nginx
cd /usr/local/nginx
mkdir conf
docker cp nginx-temp:/var/log/nginx log
docker cp nginx-temp:/etc/nginx/nginx.conf conf/nginx.conf
docker cp nginx-temp:/etc/nginx/conf.d conf.d
docker cp nginx-temp:/usr/share/nginx/html html

• 4修改nginx配置文件
  #conf/nginx.conf
  详见《附录1》
  #conf.d/default.conf
  详见《附录2》
• 5运行容器，挂在宿主资源

docker run --name nginx -d -p 80:80 -p 3306:3306 --restart=always -e TZ="Asia/Shanghai" 
-v /usr/local/nginx/log:/var/log/nginx 
-v /usr/local/nginx/conf/nginx.conf:/etc/nginx/nginx.conf 
-v /usr/local/nginx/conf.d:/etc/nginx/conf.d 
-v /usr/local/nginx/html:/usr/share/nginx/html 
nginx:latest
