How to find out mySQL server ip address from phpmy

问题:

I have access to my server's phpmyadmin. But how can I find that mysql's Ip address from phpmyadmin. My webserver and mysql is using different IPs.

Is there any way to find this out?

回答1:

The SQL query SHOW VARIABLES WHERE Variable_name = 'hostname' will show you the hostname of the MySQL server which you can easily resolve to its IP address.

SHOW VARIABLES WHERE Variable_name = 'port' Will give you the port number.

You can find details about this in MySQL's manual: 12.4.5.41. SHOW VARIABLES Syntax and 5.1.4. Server System Variables

回答2:

MySQL doesn't care what IP its on. Closest you could get would be hostname:

select * from GLOBAL_variables where variable_name like 'hostname';

回答3:

select * from SHOW VARIABLES WHERE Variable_name = 'hostname';

回答4:

The server's address is stored in config.php

回答5:

As an alternative, since you know the hostname, resolve the database server IP via hostname from the web server.

回答6:

You can ssh to your server and run this command

 ln -s /usr/share/phpmyadmin /var/www/phpmyadmin

It worked for me..
