Low usage (simplest scenario)
Above diagram described the simplest scenario for rolling out Fantastico to production. You can use this scenario for minimalistic web applications like:
- Presentation website
- Personal website
- Blog
We usually recommend to start with this deployment scenario and the migrate to more complex scenarios when you application requires it.
| Advantages | Disadvantages |
|---|---|
| Extremely easy to deploy | Does not scale well for more than couple of requests / second |
| Minimal os configuration | All components are bundled on one node without any failover. |
| Automatic scripts for configuring the os | Does not support vertical scaling out of the box. |
| Easy to achieve horizontal scaling for all components at once. | Static files are not served from a cdn. |
Setup
- Install Fantastico framework on the production machine (Installation manual.).
- Goto $FANTASTICO_ROOT
- export ROOT_PASSWD=<your root password>
- fantastico_setup_low_usage_<os_distribution) –ipaddress <desired_ip> –vhost-name <desired_vhost> –uwsgi-port <uwsgi port> –root-folder <desired root folder> –modules-folder <desired modules folder> (e.g fantastico_setup_low_usage_ubuntu.sh –ipaddress 127.0.0.1 –vhost-name fantastico-framework.com –uwsgi-port 12090 –root-folder `pwd` –modules-folder /fantastico/samples)
- Done.
It is usually a good idea to change the number of parallel connections supported by your linux kernel:
- sudo nano /etc/sysctl.conf
- Search for net.core.somaxconn.
- If it does not exist you can add net.core.somaxconn = 8192 to the bottom of the file.
- Restart the os.
