nginx centos7

mysql centos7

php centos7

自定义镜像来实现整个架构

cd /opt

mkdir nginx mysql php

cd nginx

拖入nginx和wordpress

vim Dockerfile

vim nginx.conf

打开浏览器访问192.168.31.10/workpress即完成所有内容

作业：实现elk+filebeat的容器部署

es：两个

logstash：部署一个

kibana：作为前端

dockerfile自定义镜像

filebeat ················不需要用docker
