mysqli_real_connect(): (HY000/2002): No such file or directory

change localhost to 127.0.0.1 in /etc/phpmyadmin/config.inc.php

$cfg['Servers'][$i]['host'] = '127.0.0.1';

The reason for this is that pma tries to connect to the mysql.socket if you use localhost. If you use 127.0.0.1 PMA makes a TCP connection which should work.

This worked for me.

Locate config.sample.inc.php

Change

$cfg['Servers'][$i]['host'] = 'localhost';

into

$cfg['Servers'][$i]['host'] = '127.0.0.1';

Save.

Then rename the file and remove sample from the name.

I'm trying this before

cd /opt/lampp/phpmyadmin

Then

gedit config.inc.php

Find this

$cfg['Servers'][$i]['host'] = 

If there is localhost change it to 127.0.0.1

Note : if there is '//' remove // before $cfg['Servers'][$i]['host']

I checked again http://localhost/phpmyadmin/

"phpMyAdmin tried to connect to the MySQL server, and the serverrejected the connection. You should check the host, username andpassword in your configuration and make sure that they correspond tothe information given by the administrator of the MySQL server."

I'm opening again config.inc.php and I found

$cfg['Servers'][$i]['password'] =

Fill the password with your password

It worked for me. It may work for you too.
