Step 1: Connect to Your Website
To connect to your website using wp-cli, open your terminal or command prompt and navigate to your website’s root directory. The root directory is the main folder that contains all the files and folders for your website.
To navigate your website’s root directory, open your terminal or command prompt and use the cd command. For example, if your website’s root directory is located at /var/www/html, you can use the following command:
Once you’re in the root directory, you must ensure you have the latest version of wp-cli. To update wp-cli, enter the following command:
wp cli update
This command will download and install the latest version of wp-cli. Updating wp-cli is essential because it ensures you have the latest features and bug fixes.
Step 2: Check the Current Version of WordPress
Before upgrading WordPress, you need to know the current version of WordPress that you’re running on your website. This information will help you determine whether your website needs an update and which version to update.
To check the current version of WordPress that you’re running on your website using wp-cli, enter the following command:
wp core version
This command will display the current version of WordPress installed on your website. If you’re unsure whether the version displayed is the latest version of WordPress, you can check the official website to confirm.
Step 3: Update WordPress Core
Updating WordPress Core is essential in keeping your website secure and up-to-date. To update WordPress Core using wp-cli, enter the following command:
wp core update
This command will automatically update WordPress Core to the latest version. However, if you want to update to a specific version of WordPress, use the following command instead:
wp core update --version=X.X.X
Replace X.X.X. with the specific version of WordPress that you want to update. For example, if you want to update to version 5.8, enter the following command:
wp core update --version=6.2
Step 4: Update WordPress Plugins
WordPress plugins are essential for extending your website’s functionality and features. However, outdated plugins can also pose a security risk to your website. It’s essential to keep your plugins up-to-date to ensure your website is secure and running optimally.
To update all WordPress plugins to their latest versions using wp-cli, enter the following command:
wp plugin update --all
This command will update all installed plugins on your website to their latest versions. By updating all plugins simultaneously, you can save time and ensure that your website uses the latest versions.
Step 5: Update WordPress Themes
Updating WordPress themes is essential for maintaining your website’s appearance and performance. Themes are responsible for the overall look and feel of your website. Outdated themes can cause compatibility issues, security risks, and poor website performance.
To update all WordPress themes to their latest versions using wp-cli, enter the following command:
wp theme update --all
This command will update all installed themes on your website to their latest versions. By updating all themes simultaneously, you can save time and ensure that your website uses the latest versions of all themes.
Step 6: Verify the Upgrade
After completing the update process, verifying that the upgrade was successful is essential. To verify that the WordPress upgrade was successful using wp-cli, enter the following command:
wp core version
This command will display the new WordPress version installed on your website. If the version displayed matches the version you updated, then the upgrade succeeded.
By verifying the upgrade, you can ensure that your website runs on the latest WordPress version and that all the changes and improvements have been applied correctly.
In conclusion, upgrading WordPress using wp-cli is a quick and efficient way to ensure that your website runs on the latest WordPress version. It’s essential to keep your website up-to-date to prevent security breaches and improve its performance.
