This is a guide for installing PiCluster on Ubuntu 16.04.

h2. Prepare the Environment

* Make sure the system is up to date:
<pre>
apt-get update && apt-get upgrade
</pre>

* Install prerequisites:
<pre>
apt-get install docker git nodejs npm python2
</pre>

* Add docker group
<pre>
groupadd docker
</pre>

* Add the picluster user:
<pre>
useradd -m -g users -G docker -s /bin/bash picluster
</pre>

* Start and enable docker at boot:
<pre>
systemctl enable docker
systemctl start docker
</pre>

h2. Install PiCluster

* Download the latest PiCluster version from GitHub:
<pre>
git clone https://github.com/rusher81572/picluster.git /opt/picluster
</pre>

* Change the ownership of picluster directory:
<pre>
chown -R picluster /opt/picluster
</pre>

* Switch to the picluster user and switch to the picluster directory:
<pre>
su - picluster
</pre>

* Edit the config.json file:
<pre>
vi config.json
</pre>
#* And edit the config file to suit your environment:
*NOTE*: Use the web_connect key to the value of the host systems IP address. Otherwise you will get connection errors while starting the agent.

*NOTE*: for aesthetics, I changed the picluster_config environment variable to all caps:
<pre>
cd /opt/picluster/server
sed -i.bak -e "s/picluster_config/PICLUSTER_CONFIG/g" server.js

cd ../agent
sed -i.bak -e "s/picluster_config/PICLUSTER_CONFIG/g" agent.js

cd ../web
sed -i.bak -e "s/picluster_config/PICLUSTER_CONFIG/g" webconsole.js
</pre>

* Install and run server:
*NOTE*: There is currently a problem with the @npm install@ step not installing microtime. This can safely be ignored.
<pre>
cd /opt/picluster/server
npm install
</pre>

* Install and run agent:
*NOTE*: There is currently a problem with the @npm install@ step not installing microtime. This can safely be ignored.
<pre>
cd ../agent
npm install
</pre>

* Install and run web console:
<pre>
cd ../web
npm install
</pre>

* Exit back into root shell:
<pre>
exit
</pre>

h2. Init with pm2

* Install pm2:
<pre>
apt-get install pm2
</pre>

* Install the pm2 systemd init script as the picluster user:
<pre>
pm2 startup systemd -u picluster --hp /home/picluster
</pre>

* Switch to the picluster user:
<pre>
su - picluster
</pre>

* Export the picluster config filepath environment variable:
<pre>
export PICLUSTER_CONFIG='/opt/picluster/config.json'
</pre>

* Start the server, agent, and webconsole scripts:
<pre>
pm2 start /opt/picluster/server/server.js
pm2 start /opt/picluster/agent/agent.js
pm2 start /opt/picluster/web/webconsole.js
</pre>

* Save the pm2 session to restart at boot:
<pre>
pm2 save
</pre>
