The default password encryption method of

##mysql8iscaching_sha2_password,PHP7.4connects to mysql The encryption method is alsocaching_sha2_password, you should pay attention to this place.

In order to be compatible with older versions of clients, not only PHP, but also problems during master-slave replication, the authentication method of mysql8 was changed back to

mysql_native_password.

If you use PHP7.4, an authentication error will be reported here, because 7.4 is the

caching_sha2_passwordencryption method, so I can switch to PHP7.2 here;

Without changing the configuration, you can use the following method to change the encryption method of mysql8 and change the password for the root user:

USE mysql; ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456'; FLUSH PRIVILEGES;

Newly install php7.2;

apt-get install php7.2-fpm php7.2-mysql and other extensions;

Change the listening port to something else, and nginx reverse proxy this port.
