#CHECK MYSQL PORT PASSWORD#

You can find details about this in MySQL's manual: 12.4.5.41. Verify and diagnose connection errors on your computer.

SHOW VARIABLES WHERE Variablename 'port' Will give you the port number. Port Checker is a simple tool to check for open ports and test port forwarding setup on your router. Configuration: OS: CentOS7 MySQL: MySQL Community 8 The port to the service is opened in the firewall. Netstat -tuplen is also a good idea to see what opened ports you have on the server and which ones are in LISTEN mode. 53 The SQL query SHOW VARIABLES WHERE Variablename 'hostname' will show you the hostname of the MySQL server which you can easily resolve to its IP address. I can access is locally (and via web phpmyadmin) But I can't access it from a remote computer. You need to run it from outside the VPS to see what ports they have opened. Since they are VPS, I would also check the VPS Control Panel to see if it has any option that can block ports.Īpart from that, I would run nmap on the VPS to see what ports you have opened. If the problem persists then in my case I would check iptables (I would actually delete everything in iptables just to start fresh if this could be an option) or any other firewall-enabled option. We show both type of CREATE USER commands below.

NOTE: Older MySQL client libraries (such as those base on 5.6) need an older password encryption method. And for connectivity with JDBC, I need the URL, host and port number. Just to note that, if the file nf is not in the one I mentioned above it can be in this other places: /etc/my.confĪnd if the service command does not work, then do this: sudo /etc/init.d/mysql restart Create any MySQL constructs needed by your app, and create a user with privileges to access those constructs as required by your app. When I open the MySQL command line client, it only asks me for my password.

Then simply either restart the VPS or restart the service, like sudo service mysql restart. Change it to another port not used and save the file. If any other service is running on the port 3306 then you will have to either configure MySQL. In it, look for the line that reads port = 3306. If port is still in use then check the service running on it. Simply open the configuration file in the terminal, sudo nano /etc/mysql/nf, and look for the section. My suggestion, if you are sure that the ports are closed (I find it weird for a VPS to have that port closed) is to change the configuration file of MySQL to use another.
