Article title: Having problems installing WordPress? These tips will help you solve it, and specific code examples are needed

With the development of network technology, WordPress, as a powerful open source content management system, is chosen to be used by more and more website administrators and bloggers. However, during the installation process, you may encounter various problems, such as database connection failure, white screen, permission errors, etc. This article will introduce some common WordPress installation problems, and provide corresponding solution techniques and specific code examples to help you successfully build a WordPress website.

1. Database connection failure

Database connection failure is one of the common problems during WordPress installation. Generally speaking, this may be caused by incorrectly filling in the database information. First make sure that the database host, database name, username and password are filled in correctly in the wp-config.php file. If you still cannot connect to the database, you can try the following code example:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

Add the above code to the wp-config.php file to enable WordPress debugging mode, record error information, and help troubleshoot problems.

2. White screen

Another common problem is that a white screen appears after the WordPress installation is completed, that is, the website cannot be accessed normally. This is usually caused by PHP taking too long to execute or running out of memory. You can try adding the following code to the wp-config.php file:

ini_set('max_execution_time', 300);
ini_set('memory_limit', '128M');

The above code will expand the execution time and memory limit of PHP to ensure that WordPress can run normally.

3. File permission error

Sometimes, you will encounter a file permission error during the WordPress installation process, resulting in problems such as being unable to upload files or generate thumbnails. This can be solved by modifying the file permissions. Use the following code to modify file permissions:

find /var/www/html/your-domain-name -type d -exec chmod 755 {} ;
find /var/www/html/your-domain-name -type f -exec chmod 644 {} ;

The above code sets the permissions of all folders to 755 and the permissions of all files to 644 to ensure that WordPress can run normally.
