What Is WP-CLI and How to Use It For Managing a WordPress Site

WordPress is one of the most user-friendly content management systems (CMS) due to its intuitive admin dashboard. However, managing a WordPress site can become more complex, especially as your website grows. Whether you are a regular user or a developer, you need to manage themes, plugins, and updates.

Mastering tools such as the WordPress Command-Line Interface (WP-CLI) can be a game-changer. This WP-CLI WordPress tutorial offers a comprehensive guide, covering everything from its installation to using it effectively for WordPress website management.

By the end, you’ll have a solid grasp of WP-CLI’s capabilities, equipping you to manage WordPress websites more efficiently.

While the WordPress admin dashboard offers a user-friendly experience, WP-CLI elevates website management. Using the command-line interface, you can perform tasks more swiftly and even automate various site maintenance aspects.

WP-CLI is particularly useful for WordPress developers who handle multiple sites, facilitating streamlined management directly from the command line.

What Are the Benefits of WP-CLI?

WP-CLI offers various advantages for both regular users and freelancers. Here’s why you should consider using the WordPress command-line interface:

• Efficiency – WP-CLI lets you perform tasks in seconds that could take minutes or even hours via the traditional WordPress admin dashboard.
• Bulk actions – this tool helps you manage multiple plugins, themes, or websites with a single command. It is particularly beneficial for freelancers who manage clients’ sites and want to perform bulk actions quickly.
• Remote management – with WP-CLI, you can remotely maintain WordPress websites, meaning there’s no need to log in to each admin dashboard individually.
• Automated backups – WP-CLI enables you to create automated backup routines for your WordPress site. This is handy for those with WP-CLI support in their WordPress backup solutions.
• Advanced customizations – while WordPress’ graphical interface is user-friendly, it can be limiting for more complex tasks. WP-CLI allows for advanced customization that isn’t possible through the dashboard.

WP-CLI v2

WP-CLI has come a long way, and its latest stable version is WP-CLI v2, with the newest release being 2.8.1. This release brings updated features and improved stability to help you manage your WordPress site efficiently.

Here are the minimum requirements for running WP-CLI v2:

• PHP 5.6 or later
• WordPress 3.7 or later
• UNIX-like environment (OS X, Linux, FreeBSD, Cygwin) – limited support in Windows.

Updating to the latest version is recommended for several reasons:

• Newer versions often come with security patches.
• Access to new commands and functionalities that older versions may not support.
• Improved speed and efficiency in executing commands.

How to Install WordPress via WP-CLI

Installing WordPress through WP-CLI is quick and efficient. Before starting, ensure you’ve created a MySQL database, as it’s a prerequisite for WordPress installation.

With Hostinger, you can create a MySQL database in hPanel by navigating to Databases → Management via the sidebar.

Fill in the database’s name, username, and password to create a new database.

Alternatively, follow these steps to create a new MySQL database using the command line:

1. Enter the MySQL shell by typing:

mysql -u root -p

2. Add a user and database name by typing the commands below. Replace username and databasename with your chosen values:

GRANT ALL PRIVILEGES ON databasename.* TO 'username' IDENTIFIED BY 'yourpassword';

4. Quit the MySQL shell by executing:

quit

After setting up the MySQL database, you can install WordPress from the command line. First, navigate to the public_html directory, where your website files should reside. To check the current directory, run the following:

pwd

If you’re not in public_html, navigate accordingly:

cd /home/username/public_html

Once you’re in the public_html directory, proceed as follows:

1. Download the latest WordPress core version using the following:

wp core download

2. Create a new wp-config.php with your database credentials:

wp config create --dbname=databasename --dbuser=username --dbpass=password --dbhost=localhost --dbprefix=wp_

3. Complete the WordPress installation using the wp core install command. Replace the placeholders with your details:

wp core install --url="your_domain.com" --title="Your Site Title" --admin_user="username" --admin_password="password" --admin_email="you@domain.com"

The output will confirm the WordPress installation:

How to Export/Import WordPress via WP-CLI

WP-CLI offers simple yet powerful commands for exporting and importing WordPress data. Whether moving to a new host or backing up content, these commands make the process more efficient.

How to Search and Replace Using WP-CLI

Bulk changes to your WordPress content, URLs, or database fields usually require manual effort or specialized database plugins. However, WP-CLI offers a helpful search and replace command that automates this process.

To replace a string throughout your database, run:

wp search-replace 'old-string' 'new-string'

The output will confirm the action:

Success: Replaced 'old-string' with 'new-string'.

Before making permanent changes, you can perform a dry run to preview the results:

wp search-replace 'old-string' 'new-string' --dry-run

To run a case-insensitive search, include the –regex and –regex-flags options:

wp search-replace 'old-string' 'new-string' --regex --regex-flags='i'

You can specify which databases to search and replace in with this:

wp search-replace 'old-string' 'new-string' --all-tables-with-prefix

To change your website’s domain, execute a dry run first to check what will be replaced:

wp search-replace --dry-run 'website.net' 'website.com'

If it all checks out, go ahead with the actual replacement command:

wp search-replace 'website.net' 'website.com'

The output should read:

Success: Replaced 'website.net' with 'website.com'.
