在MacOs中迁移助手后，Mysql Server无法启动

Question

I Used Migration Assistant from ios to put my things in another mac. But, after that, my MySQL Server does not run!

In System Preferences, my computer say:

the mysql server instance is not running

Whats happing?

I try this:

brew services start mysql@5.7

And receive:

Error: Formula `mysql@5.7` is not installed.

Answer 1

I do not know why, but my system automatically renamed the MySQL directory during the migration process.

I identified that the usr/local/mysql/ directory was now called usr/local/mysql-5.7.21-macos10.13-x86_64/

What I did that solved the problem, was to create a symbolic link

sudo ln -s mysql-5.7.21-macos10.13-x86_64 mysql

I rebooted my mac, and everything worked correctly.

you will probably need to identify the new directory name with the command

ls usr/local
