I typed apt-get install phpmyadmin and ran into an error saying it cannot connect to mysql (socket issue). It was normal because I forget to install mysql before, so I selected "abort" above all options given by phpmyadmin.

Then sudo tasksel and installed lamp server.

Once finished, I ran :

apt-get remove --purge phpmyadmin
apt-get install phpmyadmin

Then mysql -u root -p but I got the following error: Access denied for the following user 'root'@'localhost'

So I solved this problem by doing :

SET PASSWORD FOR root@localhost=PASSWORD('mypassword'); 

Then I successfully logged in localhost/phpmyadmin, but found this message :

The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated. To find out why click here.

I clicked here, and it showed me : enter image description here

Can I go on peacefully with mysql/phpmyadmin?

Yes that is correct. Make sure that all the $cfg['Servers'][$i] directives are uncommented! – kratos Sep 21 '13 at 2:04

OP's answer:

I solved this problem with the following :

cd /usr/share/doc/phpmyadmin/examples
sudo gunzip create_tables.sql.gz 
mysql -u root -p < create_tables.sql
mysql -u root -p -e 'GRANT SELECT, INSERT, DELETE, UPDATE ON phpmyadmin.* TO 'pma'@'localhost' IDENTIFIED BY "pmapassword"'

Then edited /etc/phpmyadmin/ on these lines :

/* Optional: User for advanced features */
$cfg['Servers'][$i]['controluser'] = 'pma';
$cfg['Servers'][$i]['controlpass'] = 'pmapassword';

Logged back in phpmyadmin, and then, the warning message had disappeared.

Also note that you may have a new warning about phpmyadmin storage not completely configured. This can be caused because you need to tell phpmyadmin the name of the tables to use their features. That can be done editing /etc/phpmyadmin/ on this lines:

$cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';
$cfg['Servers'][$i]['bookmarktable'] = 'pma__bookmark';
$cfg['Servers'][$i]['relation'] = 'pma__relation';
$cfg['Servers'][$i]['table_info'] = 'pma__table_info';
$cfg['Servers'][$i]['table_coords'] = 'pma__table_coords';
$cfg['Servers'][$i]['pdf_pages'] = 'pma__pdf_pages';
$cfg['Servers'][$i]['column_info'] = 'pma__column_info';
$cfg['Servers'][$i]['history'] = 'pma__history';
$cfg['Servers'][$i]['table_uiprefs'] = 'pma__table_uiprefs';
$cfg['Servers'][$i]['tracking'] = 'pma__tracking';
$cfg['Servers'][$i]['designer_coords'] = 'pma__designer_coords';
$cfg['Servers'][$i]['userconfig'] = 'pma__userconfig';
$cfg['Servers'][$i]['recent'] = 'pma__recent';

Note the double underscore __.

I also had to change all the tables name in /etc/phpmyadmin/ with double underscores ex.

$cfg['Servers'][$i]['bookmarktable'] = 'pma__bookmark'; 

because that was the table created after create_tables.sql execution.

VestaCP Team made and successfully tested a script to get rid of that annoying message "The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated". We hope the fix will be useful and help users. Visit the Github page for code.

The script:

  • Works from user root
  • Makes a backup of /etc/phpmyadmin/ in /root
  • Changes values in /etc/phpmyadmin/
  • Adds a mysql user pma and the table phpmyadmin (if the user or the table already exist, the script will delete them!)
  • Downloads and adds table for the database phpmyadmin
  • Cleans temp files including leftover pma.txt (contains password for pma@localhost) and old config

This Helped Me:

  1. sudo vim /etc/phpmyadmin/
  2. Add the following lines with the other $cfg['Servers'][$i]:

    $cfg['Servers'][$i]['central_columns'] = 'pma__central_columns'; $cfg['Servers'][$i]['favorite'] = 'pma__favorite'; $cfg['Servers'][$i]['navigationhiding'] = 'pma__navigationhiding'; $cfg['Servers'][$i]['recent'] = 'pma__recent'; $cfg['Servers'][$i]['savedsearches'] = 'pma__savedsearches'; $cfg['Servers'][$i]['table_uiprefs'] = 'pma__table_uiprefs'; $cfg['Servers'][$i]['tracking'] = 'pma__tracking'; $cfg['Servers'][$i]['userconfig'] = 'pma__userconfig'; $cfg['Servers'][$i]['usergroups'] = 'pma__usergroups'; $cfg['Servers'][$i]['tracking'] = 'pma__users';

  3. Now try to login to localhost/phpmyadmin. The error message should not show up any more.

In Short, whatever is the missing component error showing up just Add:

$cfg['Servers'][$i][COMPONENT] = 'pma__COMPONENT';

in /etc/phpmyadmin/

For me: I have to edited /etc/phpmyadmin/config-db.php on this line:
