This is a simple bash file to setup a system to run comet.

setupComet.sh

#you must have comet131 in /home/alerttech/Downloads

#run the following command:
#sudo visudo
#add the following to the bottom of the file
#alerttech ALL=(ALL) NOPASSWD:ALL

sudo apt install curl -y
sudo apt install git -y

git clone https://github.com/eclipse/paho.mqtt.c.git
sudo apt install libssl-dev -y
cd paho.mqtt.c
make
sudo make install

cd ~/Downloads
sudo apt-get install git-core -y
sudo apt-get update
git clone git://git.drogon.net/wiringPi
cd wiringPi
./build

#change the following lines to the version of comet that you are using
sudo chmod +x ~/Downloads/comet131
cd ~/Downloads
sudo ./comet131

#comet should be running now and it should have created both files in the home directory
#once it has, kill comet and continue
#this will change ownership of the parms and log files so that you can edit them easily

sudo usermod -a -G dialout alerttech
sudo chown -R alerttech /home/alerttech

Also, you may have to run line 34 manually as it can take comet awhile to create the files and this command may miss them.
