1. Manually create a database (library) in mysql. If there is already a database, there is no need to create it. 2. Directly access the address. If you cannot jump to install.php when accessing index.php, please jump to ./install.php manually. 3. After the installation is successful, install.php will create a config.php in the same directory. Then install.php will delete itself. 4. The background login address is ./login.php
