Using mySQL Server (Xampp) and SQL Server on the same machine - mysql

Question

I have been using Xampp to test my website stuff and everything was working perfectly until I decided to install Microsoft SQL SERVER 2017 to do some data science stuff (school stuff).
Now I can still start Apache but I cant start MySQL. Here is the log :

I tried shutting down the SQL Server using SQL Server Management but I still can't connect MySQL.

Answer 1

You can change port of sql server or mysql server and dont forget to specify the port while accessing it.

Answer 2

Since Microsoft SQL Server and MySQL/MariaDB/Percona use different ports (and it doesn't sound like you've changed from the defaults), I doubt this is related to you installing SQL Server. SQL Server uses port 1433 and MySQL port 3306.
As for what is using that port, https://stackoverflow.com/a/48199/2385479 helps us. There is a suggestion for the TCPView Sysinternals application or the alternate suggestion of using netstat (such as C:\> netstat -a -b -n) which should give you some idea of what's using port 3306.
It seems to me you probably have another MySQL server installed which is conflicting with the port XAMPP is trying to use.

Answer 3

As in the log, when you installed the SQL Server it "reserverd" the same port that your MySQL was using
2017-11-17 13:40:06 13304 [ERROR] Do you already have another mysqld server running on port: 3306 ?
You can change the MySql port in the my.ini file, which can be acessed by the Xampp Control Panel, under "config".
Or, you can change de SQL Server Port, following this tutorial: https://www.syskit.com/blog/change-sql-server-port/
