Why port = 0 in mysql and how to fix it?

Question

MySQL

I installed mysql on the centos virtual machine (for remote connection), but for some reason it gives out a zero port, I tried to change my.cnf but unfortunately the port did not change

mysql> show variables like 'port';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port          | 0     |
+---------------+-------+
1 row in set (0.00 sec)

If anyone has come across please let me know. Thanks in advance

Answer 1

Option 1 - offline mode is enabled. Can be viewed via "SHOW VARIABLES LIKE 'skip_networking';" - if in On, then look for - where it is included.
Option 2 - there are additional configuration files - in /etc/mysql.d, in /root, etc.
Bitrix, for example, has its own directory with configuration files in etc.

Answer 2

Show me your my.cnf
