Hosting Shiny App on Own Server: A Comprehensive Guide for Devs

Hosting a Shiny app on your own server can be a challenging task, but it’s also a rewarding experience. With your own server, you have complete control over the deployment and management of your app. In this guide, we’ll take you through the steps of hosting a Shiny app on your own server. We’ll cover everything from setting up the server to deploying the app and managing it over the long term.

1. Setting Up Your Server

Before you can start hosting your Shiny app, you need to set up a server. There are several options for doing this:

Dedicated Server

A dedicated server is a physical server that is solely dedicated to hosting your app. This option gives you complete control over the server and its resources, but it can be expensive.

Virtual Private Server (VPS)

A VPS is a virtual server that runs on a physical server. It’s a more affordable option than a dedicated server, but still provides you with a high degree of control over the server.

Cloud Server

A cloud server is a virtual server that runs on a cloud computing platform. This option is highly scalable and cost-effective, but may not provide you with as much control as a dedicated or VPS.

2. Installing and Configuring Shiny Server

Once you’ve set up your server, you need to install and configure Shiny Server. Shiny Server is an open-source server that allows you to deploy and manage your Shiny apps.

To install Shiny Server, you’ll need to follow these steps:

Step 1: Install R

Before you can install Shiny Server, you need to install R. You can download R from the official website.

Step 2: Install Shiny Package

Next, you need to install the Shiny package. You can do this by running the following command in R:

install.packages("shiny")

Step 3: Install Shiny Server

Finally, you need to install Shiny Server. You can download Shiny Server from the official website.

Step 4: Configure Shiny Server

After installing Shiny Server, you need to configure it. You can do this by editing the shiny-server.conf file. This file is located in the /etc/shiny-server/ directory.

3. Deploying Your Shiny App

Now that you’ve set up your server and installed Shiny Server, you’re ready to deploy your Shiny app. Here’s how:

Step 1: Create Your Shiny App

Create your Shiny app using RStudio or any other R development environment.

Step 2: Copy Your App to the Server

Copy your app to the server. You can do this using FTP or SCP.

Step 3: Configure Your App

You need to configure your app to work with Shiny Server. To do this, you need to create a shiny-server.conf file in the /etc/shiny-server/ directory.

Step 4: Start Shiny Server

Finally, start Shiny Server by running the following command:

sudo systemctl start shiny-server

4. Managing Your Shiny App

Once your Shiny app is deployed, you’ll need to manage it over the long term. Here are some tips for managing your app:

Back Up Your App Regularly

Make sure to back up your app regularly to avoid losing any data or configurations.

Monitor Your Server

Regularly monitor your server to ensure it’s running smoothly and to catch any potential issues before they become major problems.
