附：此错误为站内分享的端（想转型bc端，拿来参考，百度网盘下载了一个小时进不去，不甘心
），非个人服务器问题
1.删除产生的文件夹，因为配置问题。有可能是数据库o.luckperms.lib.mysql.jdbc.StandardSocketFactory.connect(StandardSocketFactory.java:211)
你可能是设置了数据库了，你先把配置文件全删了，开服生成新的配置文件，然后根据原来的配置文件进行修改即可解决。这种方法很笨，但是很管用
就是提示我数据库有问题，但是我之前没用过这个数据库，所以我也不太清楚是删除哪儿，服务端自带的mysql.sql文件我删掉了，它还是在报错
没有用过MySQL啊 那你也没配置MySQL服务器咯
那我估计是作者的残留
BungeeCord如果你想同步玩家权限那你需要MySQL
我不需要这个统一权限，我现在就连进都没法进去。。怎么才能把lp的mysql关闭啊？
LuckPrems\config.yml下
这个改成 h2 或 SQLite
按我的笨方法，把生成的所有文件都删了 直接删LuckPrems文件夹！，然后启动，重新配置权限就行了
我删掉了这个端里 大厅的所有配置文件，然后就能进来了
这个mysql 如果我没有自行安装使用，那么它还会存在吗，我需要服务端发布时候的起床战争权限配置之类的东西啊。
mysql是数据库，这个跟我的世界服务器不沾边，也就是不是必要的。等你有需要的时候会接触到的，现在你用不到，你可以正常的干你想干的任何事情。 你不用安装，也不需要启用，直接按你想的配置去就行，如果还是不懂，我可以提供更详细的服务。
