WP-CLI is installed on all servers. When you are logged in over SSH, run it as the wp command.
Useful commands
Create an administrator user
wp user create myuser me@email.com --role=administrator
Verify WordPress core and plugins
wp core verify-checksums
wp plugin verify-checksums --all
Install and activate a plugin
wp plugin install litespeed-cache --activate
Reinstall an existing plugin
wp plugin install litespeed-cache --force
Update all plugins
Search and replace (for example HTTP to HTTPS)
wp search-replace 'http://mydomain.com' 'https://mydomain.com' --skip-columns=guid --precise
For search-replace, add --all-tables if you need every table in the database, not only those WordPress registers via $wpdb.
Many subcommands support --dry-run so you can preview changes before applying them.
