How to host CodeIgniter on Digitalocean Droplet - ServerAvatar

CodeIgniter is an open-source PHP framework known for its features and flexibility. It allows developers to build and manage web applications efficiently, providing tools for routing, database interaction, and session management. With its extensive libraries and easy customization options, CodeIgniter facilitates the creation of web solutions without requiring advanced technical skills. For hosting CodeIgniter applications, DigitalOcean is preferable due to its scalable infrastructure and straightforward deployment options. ServerAvatar simplifies the deployment of CodeIgniter on DigitalOcean's VPS (Virtual Private Server) by offering a user-friendly setup process, making configuration and management both simple and accessible.

Create Server in Digitalocean

Digitalocean is one of the most popular cloud platforms right now. It offers on-demand cloud computing for various use cases as well as some managed solutions. We can deploy any PHP-based applications on Digitalocean Droplets. Droplets are the servers or cloud computing instances in Digitalocean. If you want to learn about droplet management in-depth in Digitalocean, We recommend you to read our Digitalocean guide.

To deploy any application on Digitalocean, We first need a Droplet. So, we will first create a droplet and perform the initial setup.

Step 1: Go to the Create Droplets page.

Log in to your Digitalocean account and click on the Create button given on the top-right corner of the page. From the drop-down menu, click on the Droplets option to see a droplet creation form.

Step 2: Choose Region

On the Droplet creation page, you will find several sections for selecting different options. We will proceed step by step.

The first thing you have to do is select the region for your droplet. Digitalocean provides several options when it comes to selecting the location. The general rule is to select the region that is closest to your audience. It means that for the majority of your audience, Your sites will load faster due to low latency.

Step 3: Choose an Image or an OS

In this step, you have to select the operating system for your droplet. Generally, the CodeIgniter application requires Ubuntu 20.04 LTS or a later version for optimal performance and support.

However, We recommend you to use Ubuntu 20.04 LTS x64 or Ubuntu 22.04 LTS x64. These operating systems are a requirement if you are using ServerAvatar to manage your droplets.

Step 4: Choose the size of the Droplet

Here you have to choose the size of your Droplet. As we mentioned above, Digitalocean provides many different types of droplets. Select the one that fits best for your project.

If your site is brand new and does not have much traffic, start with a small plan. Once the project starts getting traction, you can upgrade the plan to handle more visitors on the site.

Step 5: Choose Authentication Method

Now you have to select the authentication method. There are two types of authentication methods. They are as follows:

1. Authentication via SSH Keys
2. Authentication via Password

Using SSH keys for authentication is the best option. If you are not familiar with SSH keys, you can choose the password method. Make sure to set a strong password for your root user, which is the most powerful user with all the privileges on Linux OS.

Step 6: Selecting Additional Options

There are three additional options you can choose from. They are optional but important in different use cases. The additional options are:

1. Monitoring: It is a free feature by Digitalocean. It allows you to see additional monitoring data for your server.
2. Backups: We recommend you to enable full server backups if you are going to deploy in a production environment. The cost of the backups depends on the size of the droplet.
3. Managed Database: You do not need a Managed database if you are using ServerAvatar to manage sites on a droplet. A managed database is a pre-configured MySQL Droplet.

Step 7: Finalise Details

In the last step of this process, We have to enter the name of the droplet, and the number of droplets you want to create, Define any tags, and select the project. Enter all the details and click on the Create Droplet button to create a droplet.

In a few minutes, You will have the Droplet up and running. Now, We have to perform the initial configuration on the Droplet to host PHP-based frameworks and software.

Initial Server Configuration

The Initial server configuration includes the installation and configuration of various packages required to host your website. Usually, You have to write commands and modify configuration files. Luckily, With ServerAvatar, Your full server configuration and optimization can be automated.

Here are the three ways to automatically configure your server with ServerAvatar.

wget https://srvr.so/install
chmod +x install
./install
