Unable to connect to MySQL from Ejabberd installed in Ubuntu machine. AWS - EC2

Question

I have installed Ejabberd in Ubuntu machine (An Amazon EC2 machine). I have another machine which is a windows server and I am running MySQL in it. The service is up and running.

But for some reasons when I start Ejabberd, I am not able to connect to MySQL db which is at the windows machine. I made sure the ports are opened (3306 from the MYSQL machine).

Also, all the neccesary beam files are configured in Ejabberd Ubuntu machine. Not sure why I am not able to connect to MySQL. The error which I get in the log is below. Any help would be great. I have configured the security group in Windows machine to accept request to port 3306 also. Still not able to connect. Thanks for your help

Answer 1

I think you should check your mysql configuration file my.ini file in windows case

• locate you my.cnf or in windows case my.ini file that should locate these setting in my.ini , comment out the #skip-networking and in your case bind your IP address

  bind-address = 0.0.0.0 (Your IP)

Second thing your should give the permission of that user to connect the in mysql

GRANT ALL ON DatabaeName.* TO DBUser@'%' IDENTIFIED BY 'PASSWORD';
flush privileges;

Restart your mysql , let me know how it goes
