Step 3 Check that Nginx service has been running $ sudo systemctl status nginx Step 2 Install Nginx package $ sudo apt -y install nginx Step 1 Update apt package list $ sudo apt package ssh directory of the sudo-enabled user’s home directory when you create the VM with SSH key as the only authentication method.Īfter the sudo-enabled user is created, we proceed with Nginx installation as follows. Another thing to note is that you need to copy your public ssh key to. If you also disable root login, first ensure that you can login with the sudo-enabled user account prior to disconnecting from existing root ssh session. You can refer to this article on the relevant commands for such user creation (Step 3 in “Server Provisioning for Basic Use” section). When installing on Digital Ocean, it is recommended to create a non-root user with sudo privilege to perform the installation. If you’re just starting with Nginx, its simple installation and sufficient defaults may help improve the speed of development or testing lifecycle. Complexity may arise later in the configuration phase, especially in case of complex or high-traffic web or app deployment. Nginx installation is rather straightforward. If password authentication was chosen, you will need to type the root password. $ ssh SSH key was selected as the authentication method, you will need to supply the SSH key passphrase. To connect to the VM using SSH, the public IP address info displayed will be use as the host name and root will be the user name as follows. For the steps provided above, the VM info displayed is provided as a reference in the picture below. Finalize the VM specs and launch the VM by pressing “ Create Droplet” button.Īfter the VM is created, you can check the details of the VM under “Resources” tab of your dashboard. In this experiment, the name aml-lab-nginx is used.ħ. In the “Finalize and Create” section, assign a name for the VM. If you’re on Linux or Mac, you can use ssh-keygen command line tool to generate your SSH key.Ħ. Public key authentication is recommended from security point of view. You can authenticate using your public key (SSH key) or password. In the “Authentication” section, select authentication method. You may choose a datacenter region that is closest by network distance to you or the most users/visitors in order to minimize the latency.ĥ. Choose a datacenter region from where the VM will be instantiated. In “Choose a Plan” section, select Shared CPU > Basic and for the CPU options, choose “Regular Intel with SSD”Ĥ. In “Choose an Image” section, select Ubuntu 20.04 LTS 圆4 from “Distributions” tab.ģ. From top right menu, click Create > DropletsĢ. After user dashboard is displayed upon successful login, we then perform these steps:ġ. To start provisioning a new Ubuntu 20.04 VM, we first login to a Digital Ocean account. You can resize the VM later if traffic outgrows what the VM can handle or compute resource upgrade becomes necessary. As we fine tune the configuration, the instance may be shifting its role as a deployment environment for staging or production. We choose the smallest VM for the sake of having the setup as an experiment. We will launch an Ubuntu server VM on Digital Ocean. You can add your comment if you perform the steps on different versions of Ubuntu and can still proceed successfully. The rest of this post focuses on Nginx installation and configuration on Ubuntu 20.04. This flexibility helps in formulating different caching strategy for different types of content. Nginx can perform caching at different level: URL path, single website, or globally throughout all websites / web apps served by Nginx. Similary, when Nginx is running as a web server, there will be less time waiting for processing a request that returns dynamic content. When Nginx is configured as a reverse proxy, as for example, content caching improves content delivery speed since there will be less round trips made to the upstream server for proxying the same requests. Caching the content improves the user-perceived performance especially on the latency side. Content caching is usually combined with other type of Nginx setup, such as reverse proxy or web server. It is important to note that even though mail protocols (SMTP, IMAP, and POP) are used when sending or retrieving emails, Nginx authenticates the mail server user through HTTP-based authentication.Ĭontent caching is a mechanism to store static or dynamic content returned as responses of a request in a temporary storage (cache) so that the same request in the future can be served with the content directly from the cache.
