Using community version 8.0.23 and tried to change default port by modify the /etc/my.cnf file.

#socket=/var/lib/mysql/mysql.sock <-commented
port=12345 <-added

Then start up "systemctl start mysqld" resulted in error.

The /var/log/mysqld.log shows the following message.
2021-02-05T01:10:02.751572Z 0 [ERROR] [MY-010262] [Server] Can't start server: Bind on TCP/IP port: Permission denied
