MySQL 5.7 on Raspberry Pi

Question

Because this did not work for me: MySQL 5.7 in Raspberry Pi 2

I installed MySQL from source, and now I have MySQL 5.7.11 installed under /usr/local/mysql.

I've never used systemd, so I don't know exactly how it works. Many tutorials say use 'something like this'. Right now I would just like to start mysql, but that's failing.

pi@raspberry3:~/bin $ sudo systemctl stop mysql
pi@raspberry3:~/bin $ sudo systemctl status mysql
● mysql.server.service - LSB: start and stop MySQL
   Loaded: loaded (/etc/init.d/mysql.server)

  Process: 20735 ExecStart=/etc/init.d/mysql.server start (code=exited, status=0/SUCCESS)

Mar 29 15:33:53 raspberry3 systemd[1]: Started LSB: start and stop MySQL.

mysqld_safe exists at /usr/local/mysql/bin/mysqld_safe, so I've tried to copy it to the path /usr/bin/mysqld_safe, but that fails terribly.

Do I just need to adjust some path in some file so it may find mysqld_safe and it will start?

Thanks for any help getting MySQL running on the Raspberry!

The problem is that /etc/init.d/mysql.server is looking for MySQL in the wrong place. You are correct that copying the binary will cause problems.

One way to fix it would be to edit this file, and change occurrences of /usr/ to /usr/local/. This is what I recommend.

Another would be to uninstall MySQL completely from /usr/local and install it in /usr instead (./configure --prefix=/usr). If you use this route, make sure you uninstall it completely, removing every file it installed.
