SSH Script to automatically run a number of commands on remote servers. E.g. to restart Laravel instance

remote_servers.sh

#!/bin/bash

# exit if any of the commands fail
set -e

# import config with IP addresses
source ${BASH_SOURCE[0]%/*}/ip.conf

echo -e "Connecting to IP:$laravel";
ssh root@$worker -t "cd /var/www/ &&
php artisan down &&
php artisan config:cache &&
sudo service php7.1-fpm restart &&
php artisan up"

# can repeat for multiple servers
