Question

我已经使用MAMP安装了几个星期了，当我今天启动它时它就无法启动。没有运行mysql进程所以我检查了错误日志，当我启动服务器时显示以下内容：

130826 14:19:55 mysqld_safe Starting mysqld daemon with databases from /Applications/MAMP/db/mysql
130826 14:19:55 [Warning] You have forced lower_case_table_names to 0 through a command-line option, even though your file system '/Applications/MAMP/db/mysql/' is case insensitive.  This means that you can corrupt a MyISAM table by accessing it with different cases. You should consider changing lower_case_table_names to 1 or 2
130826 14:19:55 [Warning] One can only use the --user switch if running as root

所以很明显找不到某个日志文件，但我不知道为什么会发生这种情况，或者如何修复它。

Answer 1

似乎其中一个二进制日志文件Applications/MAMP/db/mysql/mysql-bin.000025已损坏或被删除（它不再存在，我没有手动将其删除）。

在做了一些研究并找到this帖后，我能够通过导航到/Applications/MAMP/db/mysql并手动编辑来解决此问题 mysql-bin.index不再包含丢失的日志文件。

我仍然有点困惑导致这个问题的原因，因为我正常关闭了我的MAMP服务器而从未接触过二进制日志文件......

Answer 2

对于MySQL 8.0，文件mysql-bin.index更改为binlog.index。在这种情况下，删除并重新启动MySQL即可解决问题。
