What is WP-CLI?
WP-CLI is a feature that was born and developed in 2011. With WP-CLI, you can easily manipulate and manage your WordPress website simply through the command line interface. With the usual method, when you need to install Plugins, Themes, or edit WordPress-related things, you need to access the WordPress admin and perform operations by clicking the mouse, this sometimes takes time and is somewhat cumbersome and time-consuming.
That’s why WP-CLI was developed to help you handle the above problems; even if we don’t need to access the WordPress admin, we can still manage our website quickly and save time.
So how to install and use WP-CLI?
On the Share Hosting service at AZDIGI, WP-CLI is pre-installed by default. You can use it directly from the Terminal window on the Hosting interface or use Host information to SSH through software like Putty, Xshell..etc.
So if you use Server/VPS services but do not have WP-CLI pre-installed, how to install and use it, then in this article, AZDIGI will guide you on how to install WP-CLI to your server in the most detail.
Implementation Guide
Step 1: Install WP-CLI
First, you need to SSH into your VPS as root, you can refer to how to SSH into VPS in the instructions below:
After successful SSH, you need to run the following commands in turn:
curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
php wp-cli.phar --info
chmod +x wp-cli.phar
sudo mv wp-cli.phar /usr/local/bin/wp
Command annotation:
- Download the WP-CLI tool from the Github homepage.
- Confirm successful download.
- Authorize execution of wp-cli.phar fille.
- Move WP-CLI to a partition where all users can use the command and rename it from
wp-cli.phartowp
You need to change wp-cli.phar to wp because, in the process of using the command, you just need to type wp instead of wp-cli.phar to make it simpler and easier to remember.
[root@sv106 ~]# curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar

[root@sv106 ~]# php wp-cli.phar --info
OS: Linux 3.10.0-1127.el7.x86_64 #1 SMP Tue Mar 31 23:36:51 UTC 2020 x86_64
Shell: /bin/bash
PHP binary: /usr/local/php72/bin/php72
PHP version: 7.2.33
php.ini used: /usr/local/php72/lib/php.ini
WP-CLI root dir: phar://wp-cli.phar/vendor/wp-cli/wp-cli
WP-CLI vendor dir: phar://wp-cli.phar/vendor
WP_CLI phar path: /root
WP-CLI packages dir:
WP-CLI global config:
WP-CLI project config:
WP-CLI version: 2.4.0
[root@sv106 ~]# chmod +x wp-cli.phar
[root@sv106 ~]# sudo mv wp-cli.phar /usr/local/bin/wp
So that WP-CLI has been successfully installed, you can use WP-CLI to manage your WordPress website.
Step 2: How to use WP-CLI
Note: When you install WP-CLI on server/VPS servers and perform operations as root when using WP-CLI commands, you need to add the option –allow-root after the line command otherwise, you will get a warning as below. If you are using Share host services or do not have to operate from the root user, you do not need to add this option behind.
Error: YIKES! It looks like you're running this as root. You probably meant to run this as the user that your WordPress installation exists under.
If you REALLY mean to run this as root, we won't stop you, but just bear in mind that any code on this site will then have full control of your server, making it quite DANGEROUS.
If you'd like to continue as root, please run this again, adding this flag: --allow-root
If you'd like to run it as the user that this site is under, you can run the following to become the respective user:
sudo -u USER -i -- wp
Now we will go to learn some basic commands of WP-CLI.
- Command to check the WP-CLI version
wp --info
[root@sv106 ~]# wp --info --allow-root OS: Linux 3.10.0-1127.el7.x86_64 #1 SMP Tue Mar 31 23:36:51 UTC 2020 x86_64 Shell: /bin/bash PHP binary: /usr/local/php72/bin/php72 PHP version: 7.2.33 php.ini used: /usr/local/php72/lib/php.ini WP-CLI root dir: phar://wp-cli.phar/vendor/wp-cli/wp-cli WP-CLI vendor dir: phar://wp-cli.phar/vendor WP_CLI phar path: /root WP-CLI packages dir: WP-CLI global config: WP-CLI project config: WP-CLI version: 2.4.0
- Command to check the list of supported features via WP-CLI
wp help
As shown below, you can see that WP-CLI supports a lot of features related to WordPress, to use any feature you just need to type the corresponding command: wp < Features to use >
