you have to follow the following steps :

root@server[#] vi /etc/csf/csf.conf

seach the line :

# Allow incoming TCP ports
TCP_IN = "20,21,22,25,26,53,80,110,143,443,465,587,993, 995, 2077,2078,2082,2083,2086,2087,2095,2096,28900,2896 0,28970,28860,49030,3333"

and add the port no in this line.
# Allow incoming TCP ports
TCP_IN = "20,21,22,25,26,53,80,110,143,443,465,587,993, 995, 2077,2078,2082,2083,2086,2087,2095,2096,28900,2896 0,28970,28860,49030,3333,3306"

If you don't have csf firewall on your server then you can also open the mysql port 3306 through iptables by utilizing the following iptables rule.

iptables -A INPUT -p tcp --dport 3306 -j ACCEPT
