The Perfect Server - Debian 10 (Nginx, BIND, Dovecot, ISPConfig 3.1) At the end of section 8, mine says LISTEN 17834 instead of 4027 root@server1:~# netstat -tap | grep mysql tcp6 0 0 [::]:mysql [::]:* LISTEN 4027/mysqld Mine says root@server1:~# netstat -tap | grep mysql tcp6 0 0 [::]:mysql [::]:* LISTEN 17834/mysqld Is that a problem?
The number is the process ID, not the port. The process ID is always different, you will even get a different number when you restart mysql.
