There is a ippbx_admin database user, we use the insert into ways to add (insert into the User (Host, user) values ( "127.0.0.1", "ippbx_admin");), try to log failed to succeed:

It can be found using the default localhost resolution, while the database is 127.0.0.1, previously did not pay attention to this problem, a waste of time for a long time, and then change the database host field to localhost

Related instructions use:
. 1, SELECT User, Host, authentication_string, plugin from the mysql.user; # access user information, user password field of the table is not in use, to use authentication_string, refer to the following values;
The caching_sha2_password and sha256_password authentication plugins provide more secure password encryption than the mysql_native_password plugin, and caching_sha2_password provides better performance than sha256_password. Due to these superior security and performance characteristics of caching_sha2_password, it is as of MySQL 8.0 the preferred authentication plugin, and is also the default authentication plugin rather than mysql_native_password.
2, GRANT ALL PRIVILEGES ON . The TO 'ippbx_admin' @ 'localhost' the WITH GRANT OPTION; # account all permissions granted to test.
PS: the same password for different values stored in the database, account should be more secure.
