升级PHP后MySQL无法在Mac Sierra上运行

Question

I recently upgraded my laravel valet to version 2 which installed php 7.2 through brew. I had previously been on php 7.1. I ran into a few bumps but got php and valet working but once I did I noticed mysql is no longer working. If I do brew services start mysql it shows successful but if I type mysql -v I get the following error message. ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

If I type mysql.server start I get the following error message

./usr/local/Cellar/mysql/8.0.17_1/bin/mysqld_safe: line 674: /Users/swany/.valet/Log/mysql.log: No such file or directory
2019-09-11T17:24:54.6NZ mysqld_safe error: log-error set to '/Users/swany/.valet/Log/mysql.log', however file don't exists. Create writable for user 'mysql'.
/usr/local/Cellar/mysql/8.0.17_1/bin/mysqld_safe: line 144: /Users/swany/.valet/Log/mysql.log: No such file or directory
 ERROR! The server quit without updating PID file (/usr/local/var/mysql/Chriss-MacBook-Pro-2.local.pid).

I have seen others with similar issues but when i walked through some of the solutions they didn't seem to work for me. I am hoping to be able to save all my databases I already have when mysql was running. I didn't try to upgrade mysql but it may tried as part of the valet upgrade.

Check to see if there is a mysql process still running. Run the following command:

ps aux | grep -i mysql

If you see any processes running then kill them using the

kill -9 PID

Where PID = Process ID of the MySQL process.

After the processes have been terminated, try restarting mysql and see if this solved your problem.
