连接被拒绝，无法连接到 XAMPP 上的单独 MySQL

Question

I'm having issues getting a MySQL connection in PHP using XAMPP and a separate local MySQL server (not the included MariaDB that myphpadmin is running).

I've installed MySQL on my computer separately (as I can't run MariaDB due to work reasons), it works fine in terminal and in MyWorkBench. I've updated the port to 3307 to mitigate the risk of it potentially running on the same port as MariaBD (which I have confirmed is actually not running in terminal).

My credentials are correct (as they work in terminal).

$dbobj = new PDO("mysql:host=$dbhost;dbname=$dbdatabase;charset=utf8;port=3307", $dbuser, $dbpwd);

If I try and connect using localhost I get this error: SQLSTATE[HY000] [2002] No such file or directory

If I try and connect using ip 127.0.0.1 I get this error: SQLSTATE[HY000] [2002] Connection refused

Both using port 3307, both work in terminal.

Running XAMPP v. 7.3.10-0, MySQL: 5.7, macOS Catalina 10.15

Answer 1

I'll answer my own question incase someone runs into the same issue. I had someone experienced look into this and due to the new XAMPP being run on a virtual machine there is no good solution to my problem. Install MySQL directly on the VM will be too time consuming as it won't have all packages needed etc. So best solution is to either see if work can let me use Maria DB in the interim, or use a different PHP server solution.

As far as I understand you have installed on the same mac box MariaDB and a virtual machine in with you have installed XAMPP. And you tried to make a connection between something running in the VM and something running outside on localhost.

There is something called nmap also for macOS, https://nmap.org/book/inst-macosx.html and you can use it to scan your box and see what services you have on it. Using nmap you could have seen that your not on the same environment. (?! )

Anyway I found here some guy telling a very similar story. It looks like he was able to connect the VM with the localhost and it took him a minute.

The next guy is telling about how to access your service on the host machine in your case the database by the hostname setting the network to bridge. <

On macOS you have ifconfig like on Linux, on windows it is called ipconfig, that gives you all information about all adapters you have and the different ip addresses

But you are right better ask the work to accept... something.
