Closed 5 months ago.
I get this error when I try to login in phpmyadmin: "mysqli_real_connect(): no such file or directory"
My os is ubuntu
What should I do?
I even do this
"change localhost to 127.0.0.1 in config.inc.php"
but it doesn't work
this is the status of MySQL service
`sudo service mysql status`
mysql.service - MySQL Community Server

Answer 1

Seen that you changed in config.inc.php:
localhost to 127.0.0.1
Well you could try not doing it by just adding the port-number where the mysql runs like in the example below:
$cfg['Servers'][$i]['host'] = 'localhost:3306';
Actually, I too had same problem and tried as you did which is ultimately answered everywhere in different forums.
Finally, I tried the above and worked for me. hopefully, it does work for you as well.
Good luck!
