由于nacos server需要mysql数据库，我们可以先把官方提供的mysql 脚本准备好，如果直接使用官方提供的镜像nacos/nacos-server:latest, 那么在启动时会自动帮你在mysql数据库里初始化好nacos需要的数据库，不需要再执行如下SQL脚本。
注：以下SQL为nacos官方提供运行server所支持的脚本。

查看pod, 发现是处于Running状态。
访问 http://192.168.31.129:31048/nacos/, 如果不能出来首页，那么很大可能是因为没有连上mysql数据库，可使用kubectl exec -it <pod_name> bash、 kubectl describe pod <pod_name> 或docker 命令来查看容器的日志
