Answer 3

Unfortunately none of the above have worked in my case. But finally I found solutions.

To find where is mysql.sock file, simply open xampp manager, select MySQL and click on Configure on the right. On the config panel click Open Conf File, and simply search for mysql.sock by pressing the CMD+F shortcut.

In my case, the owner of the mysql.sock was changed, and I had to change it back to root admin with: chmod root:admin mysql.sock

After that the database had been accessed.

(Q1) How can I find the socket file?

The default location for the socket file is /tmp/mysql.sock, to find the socket file for your system use this.

mysqladmin variables | grep socket

If you have just installed MySql the mysql.sock file will not be created until the server is started. Use this command to start it.

sudo launchctl load -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist

If prompted for a password you can pass the username root or other username like this. Terminal will prompt you for the password.

mysqladmin --user root --password variables | grep socket

(Q2) How can I refresh locate index

Refresh the locate db with this command.

sudo /usr/libexec/locate.updatedb

netstat -ln | grep mysql

Answer 6

The socket file should be created automatically when the MySQL daemon starts.

If it isn't found, most likely the directory which is supposed to contain it doesn't exist, or some other file system problem is preventing the socket from being created.

To find out where the file should be, use:

% mysqld --verbose --help | grep ^socket
