Error No. 2003. Can't connect to mysql server

Question

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?

Please refer this FAQ which describes how to solve this issue: http://faq.webyog.com/content/23/15/en/error-no-2003-can_t-connect.html

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.

Answer 6

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.

Answer 7

Going to services and starting MYSQL service doesn't work for me. Finally, I hit the following commands inside the MYSQL command-line client: ALTER USER 'username'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

Answer 8

There is a high chance that you are making one of the two mistakes. First : You are inputting the wrong password. check your password or change it with this command ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'very_strong_password'; In place of 'very_strong_password' give a strong password of your choice. Second: You are using '@' in the password which can be confused with the other with @localhost.

The SQL Sever might not be installed. Please refer this to install: MySQL
