Start And Enable MongoDB Service

sudo systemctl start mongod
sudo systemctl enable mongod

Debugging

Illegal instruction - MongoDB Needs AVX CPU Feature

If you get an error saying illegal instruction when running the mongod --version command, then it's quite likely due to your CPU not having AVX instruction support. If this is the case, and you are running a VM through proxmox, then you may just have to go to the virtual machine in question, and change the CPU type to host as shown below (assuming your host CPU has AVX support, which is probably does):
