Installation on a DigitalOcean droplet

Note: For a single user with moderate use, a small VM on a cloud service is likely plenty of performance for an emoncms installation. For applications with a large number of users and feeds the performance of emoncms will depend a lot on how the cloud provider implements storage. Networked disk drives will result in slow performance due to the network latency associated with the way the emoncms feed engines are implemented. VM’s on machines with local storage should provide much better performance.

Click on ‘Create’ to create a new cloud server
Select Ubuntu, standard $5/month, region e.g London then Create Droplet

Save and exit.

Start the script

wget https://raw.githubusercontent.com/openenergymonitor/EmonScripts/master/install/init.sh
chmod +x init.sh
./init.sh

Modify config.ini for non emonSD installation.

Disable emonhub installation

install_emonhub=false

Disable firmware, emonpilcd, emonsd, wifiap installation

install_firmware=false
install_emonpilcd=false
install_emonsd=false
install_wifiap=false
Set user as applicable and set emonSD_pi_env=0

user=oem
hostname=emonpi
emonSD_pi_env=0

Comment out config, wifi and setup module:

#emoncms_emonpi_modules[config]=stable
#emoncms_emonpi_modules[wifi]=stable
#emoncms_emonpi_modules[setup]=stable

Run main installation script:
```
./main.sh
```
Allow access to port 80 in firewall:
