To check, if your server has WP-CLI already installed or not, running the following command :
wp
If you see the error below wp-cli is not installed, you can continue with the tutorial to install it on the server.
[root@host ~]# wp –info -bash: wp: command not found
If you see actual command output, with the arguments listed then it means WP-CLI is already installed.
Installation Steps
1. We will first download wp-cli.phar file by the following command
curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
2. Give executable permission to the file downloaded
chmod +x wp-cli.phar
3. Finally, we will move the wp-cli.phar executable to a global location to ensure all users have access.
sudo mv wp-cli.phar /usr/local/bin/wp
We have successfully installed WP-CLI. To verify the same, run the following command
wp
Error: It looks like you’re running this as root. You probably meant to run this as the user that your WordPress install 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
