How Caddy Works?

Web servers like Caddy work by redirecting client requests to servers in the backend. They can also be set up to redirect queries to other web servers or serve websites directly from their file system. Caddy will verify its cache for the desired content whenever a client makes a request.

Deploying long-running services ("apps") on Caddy is all about having a single, consistent configuration that can be updated online over a REST API. It's that simple. Among the standard modules included in official Caddy releases are HTTP servers, TLS automation, and PKI apps. Its automated HTTPS features are its most notable attributes.

The basic procedure for using Caddy is as follows:

Activate The Daemon: With the caddy run command, you can start Caddy as a daemon.

Try The API: Apply the admin API to Caddy to ensure its configuration is correct.

Configure Caddy: Provide Caddy with a configuration to make it useful.

Run The Test: Verify its functionality by accessing localhost:2015 in your web browser or by utilizing curl.

Design A Caddyfile: Caddy can also be configured via the Caddy file.

The Config Adapter Can Be Used: We can use a configuration adaptor to transform our Caddyfile into the native JSON format used by Caddy.

Specify if Your Web Server Is Using Caddy

Caddy is an enterprise-ready server system that employs TLS by default and is

• effective

• versatile

• secure

Its Go coding, automatic HTTPS, and capacity to serve static webpages or reverse proxy are among its most notable elements. To determine if your web server is using Caddy, you need to follow the steps below:

Server Header for HTTP

Looking at the HTTP server header is one of the easiest ways to see if your web server is utilizing Caddy. Issue an HTTP request to your server and look for the 'Server' field in the response header to accomplish this. A web server that uses Caddy will have the "Caddy" label.

curl -I http://yourwebsite.com

Search for the line that begins with "Server." If it says so, you are utilizing Caddy.

Files for Configuration:

Examining the configuration files on your server is another approach to verify if Caddy is being used. The /etc/caddy/ directory is the default location for the Caddyfile, which is used to configure Caddy.

Your server is probably running Caddy if this file is there and has valid configuration info.

Process List

Additionally, you can view the server's current process list. If Caddy is in the race, it ought to appear on this list. If you see a process named ‘caddy,’ then your server is using Caddy.

Advantages and Disadvantages of Caddy Web Server

Caddy web server offers various advantages for its users. However, it also has some drawbacks that are constantly being improved.

Advantages of Caddy's Web Site

Using Automatic HTTPS

This is probably the most well-known thing about Caddy. It will switch all HTTP traffic to HTTPS and acquire and renew SSL/TLS certificates for your site automatically through Let's Encrypt.

The Easy Configuration:

The Caddyfile is an easy-to-understand and-write configuration file used by Caddy. Because of this, configuring your server might be easier and faster.

Wide applicability:

Plugins allow you to extend Caddy's capabilities as needed. Apart from the numerous pre-made plugins, you also have the choice to make your own.

Coded in the Go language:

The speed and efficiency of Go are passed on to Caddy because it is written in Go. Additionally, there are no dependencies to be concerned about because it is statically linked.

Caddy Web Server Disadvantages

Less Mature

Although Caddy offers numerous unique capabilities, it is still a relatively young project that lacks the experience and thorough testing of more established web servers.

The Limited Module Ecosystem

Although Caddy's extensibility is a strong point, the module ecosystem is not as developed or extensive as it is for other servers, such as Apache or Nginx.

Performance

In most cases, Caddy performs admirably; nevertheless, for really busy websites, its raw speed may fall short of that of competing web servers.

A Lesser Community Support

Because of its smaller user base, obtaining community support and finding solutions to issues may be a bit more complicated than with more established web servers such as Apache or Nginx.

How to Run WordPress on a Caddy Web Server

Step 1: Install Caddy

Caddy must first be installed on your server. You can either use a package manager to install it or download it from the official Caddy website.

Step 2: Configure Caddy

After that, configure Caddy so it can serve your WordPress site. Making a Caddy file with all the necessary configurations is part of this process. For example:

yourwebsite.com { root * /var/www/wordpress php_fastcgi unix//run/php/php7.4-fpm.sock file_server }

In this section, you must replace /var/www/WordPress with the precise location of your WordPress installation and yourwebsite.com with the domain name of your site. Caddy is instructed to send PHP queries to PHP-FPM using the php_fastcgi directive, and the file_server directive enables the static file server.

Step 3: Run Caddy

Now that the formatting and setup are done, you can run Caddy by using the following command:

sudo systemctl start caddy

Caddy will start running on your WordPress now. If you want to confirm the running method, use the required command.
