Cannot Start MYSQL Server Mac

Question

I am currently trying to run mysql server on a mac, but the Start MySQL Server from the preferences pane doesn't work, and neither does starting it from the Terminal. I have found a lot of fixes, but none of them work. This is my first time using MySQL, I have very little (just a bit of Java) programming experience, and this is my first StackOverflow post in a long time (please help me learn if I did it incorrectly!).

I installed this version(didn't use brew): mysql-5.7.21-1-macos10.13-x86_64 My machine is 64 bit

What I've tried:

1. Uninstalled and reinstalled MySQL using this process:

To uninstall MySQL and completely remove it (including all databases) from your Mac do the following:

Open a terminal window Use mysqldump to backup your databases to text files! Stop the database server sudo rm /usr/local/mysql sudo rm -rf /usr/local/mysql* sudo rm -rf /Library/StartupItems/MySQLCOM sudo rm -rf /Library/PreferencePanes/My* edit /etc/hostconfig and remove the line MYSQLCOM=-YES- rm -rf ~/Library/PreferencePanes/My* sudo rm -rf /Library/Receipts/mysql* sudo rm -rf /Library/Receipts/MySQL* sudo rm -rf /private/var/db/receipts/mysql https://community.jaspersoft.com/wiki/uninstall-mysql-mac-os-x

2. When I open the folder where mysql is installed, I do not have permissions to open the data or keychain folders. So, I decided it was a permissions problem and tried this: Cannot start Mysql on Mac. When I tried to start the server, I got the following error:

sudo /usr/local/mysql/support-files/mysql.server start Starting MySQL .Logging to '/usr/local/mysql/data/XXXXs-MacBook-Air.local.err'. /usr/local/mysql/bin/mysqld_safe: line 198: 7892 Trace/BPT trap: 5
nohup /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=XXXXs-MacBook-Air.local.err --pid-file=/usr/local/mysql/data/XXXXs-MacBook-Air.local.pid < /dev/null > /dev/null 2>&1 ERROR! The server quit without updating PID file (/usr/local/mysql/data/XXXXs-MacBook-Air.local.pid).

3. Tried to check the admin version and got the following error:

XXXXs-MacBook-Air:mysql XXXX$ bin/mysqladmin version mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)' Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!

4. Tried to open /temp/mysql.sock from the command line and got that it does not exist
5. Tried this:

XXXXs-MacBook-Air:mysql XXXX$ % mysqladmin variables -bash: fg: %: no such job XXXXs-MacBook-Air:mysql XXXX$ mysqladmin variables -bash: mysqladmin: command not found

6. Tried removing my.cnf per this post and restarted the server

sudo rm -rf /etc/my.cnf sudo /usr/local/mysql/support-files/mysql.server start

7. Tried these instructions MySql server startup error 'The server quit without updating PID file '

XXXXs-MacBook-Air:mysql XXXX$ ps -ef | grep mysql 501 9173

And now I'm back to this error:

ERROR! The server quit without updating PID file (/usr/local/mysql/data/XXXXs-MacBook-Air.local.pid).

Please help!

EDITED: I uninstalled and reinstalled with brew. Using these instructions: http://stefan.magnuson.co/articles/osx/reinstalling-mysql-on-osx-with-homebrew/ Now it works.
