CentOS 7 Hubot systemd (with Mattermost adapter)

• Install and setup Hubot (https://hubot.github.com/docs/) with Mattermost adapter (https://github.com/renanvicente/hubot-mattermost)
• Place hubot.system into /etc/systemd/system/

If you have more than one Hubot running on your server you can use multiple system files with different names (there may be a better way of doing this).

• Set up your Mattermost enviromental variables.
• Set the system user to run hubot as. I have my hubot running as 'hubot'
• Set your WorkingDirectory and ExecStart to point to your hubot directory

• systemctl daemon-reload
• systemctl enable hubot
• systemctl start hubot

• systemctl status hubot
• less /var/log/messages

I had a few issues with NPM permissions and global packages. I kept receiving:

• Error: Cannot find module 'hubot-mattermost'

To fix my issue I used 'Option 2' on this site: https://docs.npmjs.com/getting-started/fixing-npm-permissions and reinstalled my npm packages as hubot.
