Preparation: Confirm the server environment to support it
Before you begin, make sure you have SSH access to the server and you have PHP and WordPress installed. Generally, VPS or cloud hosts support these operations. If you are using a virtual host, it may not be suitable for using WP-CLI.
- Check if PHP is installed: Run
php -vto view the version number - Make sure that the WordPress installation directory is already on the server
If you do not have permission or are not sure how to operate, you can contact your hosting provider for help.
Download and install WP-CLI
The installation process is actually very simple, you only need to download a phar file. You can download it directly through the following command:
curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
After the download is completed, it is recommended to test whether it is running normally:
php wp-cli.phar --info
If you see the WP-CLI version number and PHP path in the output information, it means that the file is fine.
Next you can turn it into a globally available command:
chmod x wp-cli.phar sudo mv wp-cli.phar /usr/local/bin/wp
In this way, you can directly enter wp to use it.
Frequently Asked Questions and Solutions
Sometimes you will encounter permission problems or path incorrect. Here are a few common solutions:
- If prompted "Permission denied", try adding
sudobefore the command - Make sure you execute the command in the root directory of WordPress, otherwise you will prompt that wp-config.php cannot be found
- If the system does not have curl, it can be installed through the package manager (for example, use
sudo apt install curlon Ubuntu)
Some servers do not use the latest version of PHP by default. If you encounter compatibility issues, you can try to specify the PHP version:
/usr/bin/php8.1 wp --info
Just replace it with the actual PHP path on your server.
Basically that's it. The whole process is not too difficult, but you need to pay attention to whether the server environment configuration meets the requirements. Once installed, you will find that using commands to operate WordPress is much faster.
