attempted to be established!

Correct the database settings

Check your LocalConfiguration.php or AdditionalConfiguration.php files and verify that the database connection settings are correct.

Restart the MySQL daemon.

  1. Login as root on your system if you have shell access, or start a console from the server panel.
  2. type: /etc/init.d/mysql restart On Mac OSX 10.10 (Yosemite) type: sudo /usr/local/mysql/support-files/mysql.server stop
  3. If you get this error:
ERROR! The server quit without updating PID file (/usr/local/mysql/data/<SERVERNAME>.pid)

Then your next option is to kill the mysql process manually by following this instructions: http://stackoverflow.com/questions/26263889/starting-mysql-error-the-server-quit-without-updating-pid-file/26266079#26266079

  1. Then restart mysql daemon again. This time it should work. On Mac OSX 10.10 (Yosemite) type: sudo /usr/local/mysql/support-files/mysql.server start

TYPO3 6.2 - modify your MySQL configuration file

The problem could depend on recent PHP update from v. 5.3/5.4 to 5.5; a new module is installed: php-mysqlnd. So your TYPO3 attempt to establish a db connect but mysql do not use more your old encryption method for the password.

Proceed as follows:

  1. edit /etc/my.cnf
  2. remove the old_passwords=1 statement
  3. login as root in your server
  4. login to mysql as admin/root (mysql -u root -p)
  5. select database, type: use mysql;

6. just switched to mysql db change the password of the user: update mysql.user set password=PASSWORD(‘password’) where user=’db-username’ obviously substitute db-username with the ‘username’ and ‘password’ with the right (old or new password) used to access your db, stored in: typo3conf/LocalConfiguration.php 7. restart your mysql daemon: /etc/init.d/mysqld restart 8. eventually remove all site cache: rm -rif typo3temp/Cache*
