在linux操作系统中，当mysql无法启动时候，先看日志

2024-03-15T05:20:16.352075Z 0 [Warning] [MY-000081] [Server] option 'max_allowed_packet': unsigned value 107374182400 adjusted to 1073741824.

2024-03-15T05:20:18.646234Z 0 [ERROR] [MY-010041] [Server] Can't init tc log

有一行很关键

mysqld: File './mysql-bin.000002' not found (OS errno 2 - No such file or directory)

找不到 日志文件

解决很简单，就是删除“binlog.index”文件，这样MySQL将默认重建“binlog.000001”二进制日志文件，MySQL服务正常启动！

如果是高版本

是这个文件

mysql-bin.index

安全提醒

如果不确定，首次操作必须要备份文件，例如重命名文件备份法“mysql-bin-临时作废.index”

这个文件在哪里呢？

文件路径

日志文件和数据库在一起

宝塔路径：/www/server/data

默认路径：

/var/lib/mysql/
