EASY- Need ASAP Make Already Automated Linux Script into a Startup Script for a VPS - Few Lines of Code

Hello Freelancers, I have a simple job here for you guys and I am pretty sure it could be done in 15 minutes if you know what you are doing. I have an already automated proxy script which makes anonymous proxies in Squid. My Current Procedure is: Go to [login to view URL] and login Go to instances, make an instance the cheapest Instance they offer. I use centos 7 but the script is actually compatible with almost any linux os - Centos, Ubunto, Debian, and more.. Wait until Server Deploys Once that is started, download puTTy, should be the first link on Google Then open it up put the IP in puTTy Leave the port as 22 Your log in info is root and the pw would have to be copied Once you copy the pw, 2 finger tap your laptop to paste, or right click your mouse It would appear blank Click enter Then copy and paste this from wget to spi wget [login to view URL] && bash spi -rhel7 && rm "nameofscript" Then after that in PuTTy asks for a username and password, this is username and password for proxy authentication Then script asks say delete "name of script" type no Note: when you input your proxy into your bot, put 3128 as your port not 22 My goal here is to modify this script to a startup script. The reason for this is because I have to login to each server individually and copy and paste the link to the script, enter the user and password on each one.. Sometimes I need to make 100-200 proxies.. So I want to just be able to deploy these servers and have the script install automatically.. ----- This would be a bonus if it is possible but vultr has an option to have more than 1 IPv4 address at a time.. I would love it if we could get this startup script to recognize the other IP addresses and also turn those into proxies.. But this would be a bonus and only if you have enough experience for this.. Happy Bidding.. Please do not bid if you don't know how to do this or this seems like a major project to you.. The project is almost done it just needs to be slightly modified.
