I just moved Jira Software from a Bluehost CentOS server to a Digital Ocean CentOS droplet and every time I try to start it up, it "loads" (shows the loading graphic and steps and completes the process) and then immediately crashes (I get a blank page and when I refresh, there is nothing to connect to). I first tried it with 1 CPU and 2 GB RAM (50 GB disk space so that isn't the problem) and then moved it to 2 CPUs with 2 GB RAM and I'm still getting GC Allocation Failures. Here is my latest log:

I started the migration following the steps at https://confluence.atlassian.com/adminjiraserver/migrating-jira-applications-to-another-server-938846962.html only when I got to the point where I upload the XML backup, it crashed. Then the next time, after restarting Jira, I was asked to provide my license (no XML backup upload option) and then it crashed. The time after that, after restarting Jira, I was asked again for my license and then to create an admin account and then it crashed, and now it just "loads" and crashes.
My old server did have a different hostname (of course, since I didn't get to the point where I can change it or feel secure enough to point my old domain to the new one) and it was on port 80, but that shouldn't matter because I was able to access my new server by IP address and on port 8080 (I should be able to change the hostname later).
One thought I had is because Digital Ocean droplets are so bare-bones (I had to install nano), perhaps I'm missing some crucial utilities. I did install and configure MySQL as best I can according to the documentation but maybe I'm missing something else?
Let me know if there is anything else I can provide. I also could switch to a different distribution of Linux if it's easier (perhaps specifically for Digital Ocean). I'd prefer to avoid migrating to Windows for various reasons, even if it is easier (not sure it is).
This is the second time I've tried this migration so I'd really like a little assistance now.
EDIT: As far as the complexity of my Jira server, there are quite a few projects in it but not many users and I primarily use it with just a handful of developers, so I shouldn't need more than the bare minimum requirements. I had to move off of Bluehost because Jira was working but crashing almost every day because I have a 2 CPU + 2 GB RAM VPS there that's also hosting between 10 and 20 WordPress sites, so the fact that it worked there at all means it should be fine on its own in this new droplet.
