错误！服务器退出而不更新PID文件 - Mysql服务器未启动

Question

当我尝试启动mysql时

Password:
ERROR! MySQL server PID file could not be found!
Starting MySQL
.Logging to '/usr/local/mysql/data/F.f.com.err'.
ERROR! The server quit without updating PID file (/usr/local/mysql/data/F.f.com.pid).

没有运行 mysql 进程

F:data app$ ps aux | grep mysql
app      1665   0.0  0.0  4269080    816 s002  S+   11:00PM   0:00.00 grep mysql

当我尝试访问文件时

FWS:~ app $ ls /usr/local/mysql/data/F.f.com.err
ls: /usr/local/mysql/data/F.f.com.err: No such file or directory
FWS:~ app$

Answer 1

sudo chmod -R 777/usr/local/mysql/

在给予完全许可后，它起作用了。不知道权限是如何被覆盖的
