MySQL and PHP is a love story that started long time ago. However the love story with MySQL 8.0 was a bit slower to start… but don’t worry it rules now !
The support of MySQL 8.0’s new default authentication method in PHP took some time and was added in PHP 7.2.8 and removed in PHP 7.2.11. but now it’s fully supported in PHP 7.4 !
If you have installed PHP 7.4, you can see that the new plugin
is now available:
# php -i | grep "Loaded plugins|PHP Version " | tail -n2 PHP Warning: Module 'mysql_xdevapi' already loaded in Unknown on line 0 PHP Version => 7.4.0 Loaded plugins => mysqlnd,debug_trace,auth_plugin_mysql_native_password, auth_plugin_mysql_clear_password, auth_plugin_caching_sha2_password, auth_plugin_sha256_password
So no need to create a user with
as authentication method in MySQL 8.0
In summary, if you want to use a more secure method to connect to your MySQL 8.0 form your PHP application, make sure you upgrade to PHP 7.4
The drawback of this new mysqli.so is that if you don’t modify the
and by adding a value to
, when you try to connect to MySQL on
without specifying the socket path, the connection will fail with the following message:
PHP Warning: mysqli::__construct(): (HY000/2002): No such file or directory in <name of your file>.php on line 45 An error occurred when trying to establish a connection to the database: Error #2002
You have then 2 solutions:
- add in
php.inia default value for
- or specify the socket path when you initiate the connection to MySQL using
mysqliin your code
This is also the default behavior on Ubuntu when using PHP 7.4 from ppa:ondrej/php repository.
