MacOSX homebrew reset mysql root password

4down vote

If brew installed MySQL 5.7, the process is a bit different than for previous versions. In order to reset the root password, proceed as follows: sudo rm -rf /usr/local/var/mysql mysqld --initialize A temporary password will be printed to the console and it can only be used for updating the root password: mysql.server start mysql -uroot -pTEMPORARY_PASSWORD mysql> SET PASSWORD FOR '目標使用者'@'主機' = PASSWORD('密碼'); mysql> flush privileges;

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

When you got the server running via

mysql.server start

you should see the socket in /tmp/mysql.sock. However, the system seems to expect it in /var/mysql/mysql.sock. To fix this, you have to create a symlink in /var/mysql:

sudo mkdir /var/mysql

sudo ln -s /tmp/mysql.sock /var/mysql/mysql.sock

After MySQL install via Brew, I get the error - The server quit without updating PID file

I found that it was a permissions issue with the mysql folder.

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