You fall into OGP's minimum requirement of RAM. You can try it
If you're having a hard time installing OGP, you can check out the article on installing OGP on CentOS 7.

i use pterodactyl now on my vps . my vps have enough ram now . but thanks for the suggestion i probably will check it out on lower end vps 

pterodactyl worked great . it uses docker for containerization making each server each container . i used to install ogp before but i kinda didnt understand at that time
