Use Linux server as personal Proxy server

Hello,

I want to use my cheap Linux KVM VPS IP address as a personal proxy server. The server runs on CentOS 7 64bit Minimal. It has 40 GB hdd but only 1 GB RAM.

I need you to install something popular and safe that will allow only me to use the server IP as a proxy.

I need you to provide me the following info once you have done the config:

Port number
Username
Password
SSL or SOCK5?

Please note that I use proxifier as client so it needs the info above to connect.

Also, I need you to send me instructions/command lines in TXT file to change the root pass as well as the proxy pass so I can change it when you have finished.

Please make sure the proxy does NOT store LOGs to avoid the hard disk full with the proxy logs.
Also when I reboot the server the proxy should start automatically.

Thanks
