I has had two days searching and exploring solutions regarding the error 2003. Can't connect to mysql server on 'Server name'.
The firewall is off and I had added the port 3306, the one that mysql uses.
Any recommendation?

Error No. 2003: Can't connect to MySQL server on 'localhost' (or some other host)
simply means that connection is not possible for one of the following (or similar) reasons:
There is no MySQL server running at the specified host
Connection to the MySQL server is not allowed using TCP-IP. Check the 'skip-networking' setting in the MySQL configuration file (my.ini on Windows, my.cnf on Unix/Linux). It shall be commented out like '#skip-networking'. If it is not commented out, then do it and restart the MySQL server for the change to take effect. SQLyog needs to connect using TCP-IP.
Some networking issue prevents connection. It could be a network malconfiguration or a firewall issue.
When trying to connect to a MySQL server at an ISP this error message often indicates that direct connection to MySQL has been blocked. You must then use HTTP-tunneling or SSH-tunneling to connect.
if your question refer to can't connect to mysql on hosting (cpanel), i also had same problem. I also turn off firewall, but it doesn't solve my problem. Rather than using server name or domain name on Mysql Host Address, i using ip address given by hosting provider. And it works.
this could be due to firewalls of the system try below command and check
service iptables stop
The SQL Sever might not be installed. Please refer this to install: [MySQL][1]https://dev.mysql.com/downloads/installer/
Unless you are using other system
Please follow theses instructions
try to use wampserver to test your code
It worked for me.controll pannel->administrative tools->services->mysql and start mysql.Some times simple solution saves lot of time.
