Setting up crontab-ui on raspberry pi

In this tutorial I will show you how to setup crontab-ui on raspberry pi.

Step 1

Find your architecture
uname -a
Linux raspberrypi 4.4.50-v7+ #970 SMP Mon Feb 20 19:18:29 GMT 2017 armv7l GNU/Linux
Note that it is ARMv7. Download and extract latest node.
tar xz node-v7.7.2-linux-armv7l.tar.xz
sudo mv node-v7.7.2-linux-armv7l /opt/node

Step 2

Remove old nodejs if it is already installed and add the latest node to the $PATH
sudo apt-get purge nodejs
echo 'export PATH=$PATH:/opt/node/bin' > ~/.bashrc
source ~/.bashrc

Step 3

Install crontab-ui and pm2. And start crontab-ui.
npm install -g crontab-ui
npm install -g pm2
pm2 start crontab-ui
Now your crontab-ui must be running. Visit http://localhost:8000 on your browser to see if it is working.

Step 4 (Optional)

In order to be able access crontab-ui from outside, you have to forward the port 8000. Install nginx and configure.
sudo apt-get install nginx
sudo vi /etc/nginx/sites-available/default
Paste the following lines in the file:
server {
    listen 8001;

    server_name localhost;

    location / {
        proxy_pass http://localhost:8000;
Restart nginx
sudo service nginx restart
Now, crontab-ui must be accessible from outside through port 8001. So, to access crontab-ui, go to
<ip address of pi>:8001
You can also setup http authentication by following this.
