This is a guide for installing PiCluster on Arch Linux ARM using a Raspberry Pi 3. 

 h2. Prepare the Environment 

 * Make sure the system is up to date: 
 <pre> 
 pacman -Syu 
 </pre> 

 * Install prerequisites: 
 <pre> 
 pacman -S docker git nodejs npm python2 
 </pre> 

 * Use npm to install node-gyp globally: 
 <pre> 
 npm install -g node-gyp 
 </pre> 

 * Add the picluster user: 
 <pre> 
 useradd -m -g users -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.

 * 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 server 
 npm install 
 node server.js 
 </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 
 node agent.js 
 </pre> 

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

 h3. systemd services 

 h2. Init with pm2 

 * Install pm2: 
 <pre> 
 pacman -S pm2 
 </pre> 

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

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

 *NOTE*: I needed to set the config file path in the server.js, agent.js, and webconsole.js scripts to the absolute config path: 
 <pre> 
 cd /opt/picluster/server 
 sed -i.bak -e "s/..\/config.json/\/opt\/picluster\/config.json/g" server.js 

 cd ../agent 
 sed -i.bak -e "s/..\/config.json/\/opt\/picluster\/config.json/g" agent.js 

 cd ../web 
 sed -i.bak -e "s/..\/config.json/\/opt\/picluster\/config.json/g" webconsole.js 
 </pre> 

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

 cd ../agent 
 pm2 start agent.js 

 cd ../web 
 pm2 start webconsole.js 
 </pre> 

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