Warning: mysqli_connect(): (HY000/2002): No such file or directory

Question

I'm trying to install vanilla forums on my Mac, and for this I just created a database and a user from the MySQL command line:

mysql> CREATE DATABASE vanilla;
Query OK, 1 row affected (0.00 sec)

mysql> create user 'vanilla_user3'@'localhost' IDENTIFIED BY 'vanilla_password';
Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON * . * TO 'vanilla_user3'@'localhost';
Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

So I try to connect using the following code:

$con=mysqli_connect("localhost","vanilla_user3","vanilla_password","vanilla");
if (mysqli_connect_errno($con)) {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

but unfortunately, I get an error saying

Warning: mysqli_connect(): (HY000/2002): No such file or directory in /Users/kramer65/Sites/vanilla/info.php on line 3 Failed to connect to MySQL: No such file or directory

Any idea where I'm going wrong?

Answer 1

Alright, I just found the solution. The problem turned out to be that the host shouldn't have been localhost, but 127.0.0.1. I always thought localhost and 127.0.0.1 was the same, but it turned out to be different.

So maybe as a tip for future users, always use the ip when in doubt.
