The projectname variable can be whatever you want. When Django starts the project it will use this name.
The hostname will be inserted into "ALLOWED_HOSTS" in your app settings. Multiple hosts are not supported at the moment so set this to the address you'll test with. You can add additional hosts by manually editing ```settings.py```.
```install_epel_release=True```
If you are installing this on a system with the minimal CentOS build you'll need install_epel_release to be True. ```epel_release``` installs nginx. Kinda hard to run the site without that.
The hostname will be added as an environment variable for gunicorn. Multiple hosts are not supported at the moment so set this to the address you'll test with. You can add additional hosts by manually editing ```settings.py```.
## Install
### Dependencies
In order for this script to work its magic you'll need a few packages provided by Yum. This part is likely to break due to Yum's inconsistency accross distributions, firewall and proxy configurations, and whether CentOS had its morning coffee.

The first part of the script is fairly straight forward. If you aren't root user, the installer can't use yum and won't work. After checking if you are the root user it creates the necessary directories to prevent future complaints and installs the aforementioned epel-release package if you want it.

if [ $? -ne 0 ] ; then
echo -e "firewall failed to update port 443 correctly, (this may not be an issue). $firelogmsg"
fi
echo -e "firewall-cmd --reload" >> $firelogloc

if [ $? -ne 0 ] ; then

if [ $? -ne 0 ] ; then
echo -e "semanage failed to set permissive. See $firelogmsg"
echo -e "\tfirewall failed to update port $port correctly. $firelogmsg"
exit 1
fi
done
```
The firewall commands are specific to a CentOS 7 minimal install. You may not need them. The installer doesn't really care if they fail because they aren't mission critical. It'll yell at you and that's about it.
The **semanage** command fixes an issue where the websocket would be inaccessible after an install.
The next part of the script opens the necessary ports through ufw.
