错误。 服务器退出而不更新 PID 文件 (/usr/local/mysql/data/Mac.local.pid)

Question

After install, run fine mysql and restart my mac, i get this error, when i call this command line:

sudo /usr/local/mysql/support-files/mysql.server start

Hier the error:

ERROR! The server quit without updating PID file (/usr/local/mysql/data/Mac.local.pid).

And when i try to connect me to mysql -u root -p , this error:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

I try the solution in this link MySQL does not start when upgrading OSX to Yosemite or El Capitan , but nothing. I also try to change the owner of the mysql folder with:

sudo chown -R _mysql:_mysql /usr/local/mysql/

But nothing.

Any ideas?

Thank

Answer 1

start your mysql in safe_mode.its working for me. hope it would work also for you

/usr/local/mysql/bin/mysqld_safe start

Answer 2

I had to uninstall mysql

brew uninstall mysql@5.7

and reinstall again

brew install mysql@5.7

When I check my terminal I could see this warning

 [ERROR] --initialize specified but the data directory has files in it. Aborting.

then I had to do this

rm -rf /usr/local/var/mysql

and open my.cnf like this

nano /usr/local/etc/my.cnf

and remove this line mysqlx-bind-address = 127.0.0.1

then do the post-install like this

brew postinstall mysql@5.7 

Which finally worked. I had wasted a whole day on this. Hope someone finds this useful.
