Question

MySQL突然无法保持打开状态。我试过了 ps -ef | grep MySQL的须藤杀死-9 5211

我尝试删除my.cnf 我尝试按照上一篇文章的建议创建一个新的my.cnf

什么都没用。输入密码后，“系统偏好设置”中的mySQL打开，几秒钟后关闭。

这是错误日志：

这是错误。我会检查它的意思。

Answer 1

由于您已经删除了.cnf文件，因此它期望当前文件夹中的./ibdata1文件，并且该文件不存在。通常，数据目录是在.cnf文件中使用datadir属性定义的。例如

datadir=/var/lib/mysql

这个ibdata1在datadir文件夹中。
