I just got my own VPS with CentOS 7, and I'm trying to install GitLab on it. I'm following the instructions listed here. My problem is the command
systemctl start postfix. I did the
yum install postfix, and this is what resulted:
Then when I run the start command, I get the following error:
failed to start postfix.service: Unit not found
I've tried to Google the error, but all the results I've found were other issues. I'm new to this. Am I missing something really silly?
