我的mysql服务器有问题。当我启动MAMP时,Mysql服务器不会启动。我试图改变端口,但它没有帮助。我查看错误日志,我发现了这个:

我希望有人可以帮我解决这个问题。

我不知道这是否是你的问题,但我尝试用killall -9 mysqld
杀死mysqld,并尝试在Activity Monitor中查找运行的mysqld,但它并不存在。
最终我把它解决了:在我遇到问题之前发生的事情是mysqldump被中断了。这破坏了表空间。所以我退出并重新启动MAMP PRO(服务器未设置为自动启动)。然后使用MAMPs文件>更改了my.cnf编辑模板。并添加了行innodb_force_recovery = 1
。之后服务器开始运行良好。修复后我注释掉了这一行。

从MAMP / db / mysql56文件夹重命名所有文件ib_logfileN(N是数字)。 mv tmp_ib_logfileN 然后重启MAMP。 享有
