wordpress 连接mysql认证问题

Question

老师好，部署了mysql和wp容器，docker ps看都是运行，但是我看了下wp容器的logs，出现容下的内容，过了几秒，wp容器就自动exit了，查了半天没有看找到答案啊。。。

[root@docker-node1 vagrant]# 

[root@docker-node1 vagrant]# docker ps

您好，可能是mysql最新版本的问题。您可以在mysql image那指定版本，比如mysql:5.7试试

  老师，我想请问哈这个版本的问题。我怎么清楚这个版本应该是多少的呢？？

  这个比较特殊，应为mysql的新版本认证方式发生了变化，所以我们这里用5.7这个稍微旧一点的版本。
