11. access the http://cacti_IP:/cacti with your web browser.

The following error was displayed in my web browser.

Cannot connect to MySQL server on 'localhost'. Please make sure you have specified a valid MySQL database name in 'include/config.php'

I checked the web for the solution. the httpd user can't access to the db.php

chown -R apache:root /etc/cacti/db.php

chown -R apache:root /var/lib/cacti

Then, I can display the initial setup screen for cacti.

continues with the default value. then finished setup wizard.

I saw the login screen. The username and password should be 'admin'. But I couldn't log in.

I searched the web again and got the solution.

Edit the php.ini file and changed the following settings.

mysql> update user_auth set password=md5('admin') where username='admin';
