Mysql Server Has Gone Away 2006
The best answers are voted up and rise to the top What's causing this ERROR 2000 (HY000): Unknown MySQL error up vote 2 down vote favorite I have a MySQL server with version 5.6.12-log (it's running on OpenSUSE). I can connect to it from another server (CentOS 6) using: mysql -h **** -u **** --port **** -p It prompts me for my password and connects just fine. The client version is "Ver 14.14 mysql error 2002 Distrib 5.6.12, for Linux (x86_64) using EditLine wrapper." However, from another server (running CentOS 7), using the same command, I get the following error after entering my password: ERROR 2000 (HY000): Unknown MySQL error This error is useless. There is nothing in the client machine logs that indicate the cause of the failure. However, I do know that the MySQL server is at least receiving the connect request because it logs a warning about the Reverse DNS lookup not matching. It's just a warning—not the cause of this problem—but it proves that firewalls and/or network configurations aren't blocking the connection. There is nothing else in the MySQL server log (or error log) that indicates the cause of the failure. This client version is "Ver 14.14 Distrib 5.6.23, for Linux (x86_64) using EditLine wrapper." Help??? I'm lost here. In 10+ years of MySQL admining, I've never seen this error before. I don't even know where to begin. mysql errors share|improve this question asked Feb 11 '15 at 16:19 Nick Williams 1212 This is a client error. Is it possible you use some other version (not 5.6.23) to check whether the error persists or not? –ypercubeᵀᴹ Feb 11 '15 at 16:30 I wouldn't know how to use another version of the client from

Local Community Meetups Laravel.io Site and Community Forum Configuration, Database Solving: mysqlnd cannot connect to MySQL 4.1+ I have an old built project http://laravel.io/forum/04-16-2014-solving-mysqlnd-cannot-connect-to-mysql-41 that i would like to port over to Laravel, which i am https://ubuntuforums.org/showthread.php?t=804021 working on locally but when testing the connection with the live server DB i get the old: SQLSTATE[HY000] [2000] mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD =...... Whats the best mysql error way or how could i achieve this without having to create a new db and then eventually port all data over? simondavies 2 years ago derak-kilgo 2 years ago Solution You don't have to make a new DB or even change the password. You just need to set the password again and specify that it be saved in the new format has gone away to make the mysqlnd driver happy. To fix it, just update the password. mysql> SET @@session.old_passwords = 0; Query OK, 0 rows affected (0.00 sec) SET PASSWORD FOR 'existinguser'@'localhost' = PASSWORD('existingpass'); Query OK, 1 rows affected (0.00 sec); This will ensure that the password is saved in the new format. Other modern clients shouldn't have a problem connecting using this new format. (including mysql, mysqli and pdo) The only exception is anything built in C with the pre-4.1 driver. If you're only connecting with php, then you'll be fine. Since you've got an existing application. I'd make a new mysql user just for the laravel application and set a new password. That makes everyone happy. Your old stuff can still connect the way it always has and your shiny new laravel app can connect too. The info is in the mysql docs. Google for 'mysql docs password-hashing.html'. Should be the first result. simondavies 2 years ago @derak-kilgo thanks for the feedback probably correct about setting the app a new user etc. Will give this ago and get back to t

I upgraded to 8.04 recently and during the upgrade process Ubuntu asked me if I wanted to change one of my mysql configuration files and I must have clicked yes which is why I am in a bit of a pickle now.
