我的mysqld.log文件很大，大约1.2GB，从2014年开始保存数据。如何从本月删除旧记录并仅保留记录？问题是我的数据库连续两天崩溃，恢复后没有再次启动。以下是日志文件的摘录：

您必须访问mysql并检查二进制日志以使用以下命令决定您要删除的位置： ls -la / var / lib / mysql /

您可能会得到一些这样的日志 -rw-rw ---- 1 mysql mysql 104871967 Aug 24 00:01 BINLOG.015687 -rw-rw ---- 1 mysql mysql 104885618 Aug 24 00:04 BINLOG.015688 -rw-rw ---- 1 mysql mysql 104866713 8月24日00:06 BINLOG.015689

然后在日期之前删除日志：在2013-08-24 00：06：00＆＃39;;
