1. Quit MAMP
2. Open the terminal

check that mysql-server already installed if not sudo apt-get install mysql-server

Answer 3

Since you did not mention MAMP, I am assuming you are not using it so this is for a manual install but it will likely also work for MAMP.

In my experience, this is caused by the socket variable of your mysql. By default, MySQL uses /tmp/mysql.sock.

You can get the MySQL socket variable by logging into your MySQL and doing

show variables like '%socket%'

that will show you the location of the socket file.

Now, create a php phpinfo() file and look for mysql.default_socket under the mysql or mysqli section. Mine was /var/mysql/mysql.sock. This shows that PHP is looking for the file in a different location than mysql is using.

Assuming you have same values, open new terminal and enter

cd /var
mkdir mysql
cd mysql
ln -s /tmp/mysql.sock mysql.sock

this will create a link to the mysql socket file inside the location PHP is checking from.

PHPMyAdmin should work now.

Am using MAMP on a macbook pro running High Sierra, and in my case, I tried all the above but it still did not work for me so I did the following :

1. Looking for where you installed your MAMP and more specifically, look for the "config.inc.php" file located in "/Applications/MAMP/bin/phpMyAdmin".

2. Backup (ie. on a mac, right click and duplicate) the "config.inc.php" file before we touch it. You can call or rename it "config_old.inc.php"

3. Open the file in your favorite IDE or text editor.

4. Look for the following lines ;

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

ii) $cfg['Servers'][$i]['port']

iii) $cfg['Servers'][$i]['socket']

Change from :

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

to :

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

Change from :

$cfg['Servers'][$i]['port'] = '3306';

/this might be your default. Just check to see from your MAMP installation preference , press CMD + , and confirm that port number you have specified. In my case I had changed it to 8889./

to :

$cfg['Servers'][$i]['port'] = '8889';

Again depending on where you installed your MAMP or to be more specific your mysql.

Change from :

$cfg['Servers'][$i]['socket'] = 'some_folder_path or EMPTY';

to :

$cfg['Servers'][$i]['socket'] = '/Applications/MAMP/Library/bin/mysql/mysql.sock';

After this modification, save and refresh in your web browser.

Worked for me. Hope this helps. Cheers.

Answer 5

The problem I had with this was because PHP was trying to connect via a UNIX socket instead of TCP. This is similar to this error: Error when connecting to MySQL using PHP/PDO

First, make sure you have a my.cnf config for mysql then add your default socket location:

[mysqld_safe] socket = /tmp/mysql.sock

Next in your php.ini, let PHP know where it is:

mysql.default_socket = /tmp/mysql.sock

Answer 6

Check the config file:

/* $cfg['Servers'][$i]['host'] = 'localhost'; */
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['compress'] = false;

Restart MySQL: OSx : sudo /usr/local/mysql/support-files/mysql.server restart

Linux: sudo service mysql start (Old linux: sudo /etc/init.d/mysql start)
