1.可能原因：由于安装的mysql拒绝外部连接

　　修改方法，依次执行以下三句话：就可以开放权限，让外部机器连接（需要修改第二句中的username和password）

　　mysql>update user set host = ‘%‘ where user=‘root‘;

　 mysql>grant all privileges on *.* to ‘usename‘@‘%‘ identified by ‘password‘ with grant option;

　　mysql>FLUSH PRIVILEGES;

可能原因：由于mysql中配置的最大线程池太少，需要修改大一些

找到本地mysql的安装目录：修改my.ini 文件

以上是关于apollo启动失败的主要内容，如果未能解决你的问题，请参考以下文章

如何为 apollo 客户端生成片段类型？

为啥 Apollo 无法在 Xcode 中构建 - 只能有一个名为 ...的片段？

从 Apollo 缓存中读取特定类型的所有片段

使用 Apollo 客户端的片段组合：约定和样板

Apollo 客户端片段不嵌入数据

Apollo 可以从缓存中读取部分片段吗？
