   2. Run and configure the Phpdig database

Open the browser input http://localhost/phpdig/press ENTER, the page lists all Phpdig files and include folders, find a Find no default first page file (Default,index), Click search.php file for error: Unable to connect to database:check the connection script. Hint cannot complete the database connection, originally we have not completed the Phpdig database configuration. Go back to the admin directory to find the install.php file, click to run, at first glance, the English-language interface (explain, Phpdig currently all versions do not support Chinese interface), no relationship, if you have the Chinese experience may wish to do their own Chinese, here to provide a copy of my own Chinese cn-language.php Download the document (please copy it to the locales directory). In addition, you will need to modify the config.php files (language modifications) and style.css files (font modifications and style modifications) in the includes directory.

Enter install.php after the system requires us to enter Phpdig Admin username and password, by default, are admin, enter after the following interface (after the Han):
