I ran into the following issue while installing CMSMS 2.3-beta6 on a CentOS 7 server, with Apache 2.4, PHP 7.3 and MySQL (Percona) 8.0.15. I installed from the PHAR file, i.e., cmsms-2.3-beta6-install.php.
After I created a MySQL user and database for CMSMS, I entered these details in the corresponding screen in the installation process, and got the following error:
I found out that MySQL changed the default authentication plugin from mysql_native_password to caching_sha2_password as of version 8.0.4. You can read more about this here:The server requested authentication method unknown to the client
https://dev.mysql.com/doc/relnotes/mysq ... 8-0-4.html
https://dev.mysql.com/doc/refman/8.0/en ... 2-password
This has no effect when MySQL is upgraded in place for an existing CMSMS installation. The problem arises when a new database user is created, in MySQL version 8.0.4 or later.
Code: Select all
mysql> CREATE USER 'cmsuser'@'localhost' IDENTIFIED WITH mysql_native_password BY 'YourPasswordHere';
I trust that future versions of CMSMS (or perhaps I should say, future versions of the PHP MySQLi extension?) will support the newer SHA2 authentication mechanisms.
I am posting this here in hope that it may be useful to someone. I am new here, so if I posted in the wrong place then please point me in the right direction.
P.S. The eagle-eyed reader may have noticed that I'm on PHP 7.3, while CMSMS 2.3 officially calls for <=7.2. I'm pleased to say I've had no issues so far.
