A web server is in charge of managing web pages and sending them through the network to those who require it and have the permissions for those pages. In other words, it is nothing more than a software with processes waiting for a user connected to it to request the content to store, when a request arrives, the web server, generates its own processes to deliver the content through HTTP protocol. We also have even spoken on this site of them on other occasions.

Here is Caddy

Caddy is the HTTP/2 web server with automatic HTTPS. That’s the description they give us on their website. It is a lightweight, commercially supported web server that can acquire and renew SSL/TLS certificates automatically using Let’s Encrypt.

Among its most outstanding features are:

• Easy configuration with the Caddyfile.
• Automatic HTTPS on by default (via Let’s Encrypt)
• HTTP/2 by default. In other words, this is important to maintain the security of our websites.
• Virtual hosting so multiple sites just work.
• Experimental QUIC support for cutting-edge transmissions.
• TLS session ticket key rotation for more secure connections.
• Extensible with plugins because a convenient web server is a helpful one.
• Runs anywhere with no external dependencies.

As can be seen, it is an interesting and practical web server. It comes to add to the list that already conform the veterans apache and nginx.

Install Caddy on CentOS 7

Installing Caddy on Linux is simple and we can “build” our program through its download section.

Another alternative is to use curl to download it to further simplify the process. In this article I will do it this way.

First, create the a folder called “caddy”.

:~# mkadi -p caddy

Then, change the current working directory and finally run curl to download it.

:~# cd caddy
:~# curl https://getcaddy.com | bash -s personal

Note: If you don’t have curl installed, you can do it by running on a terminal yum install curl as root user.

Next you have to create an html file in the caddy directory.

:~# nano index.html

For example, something like this.

Save and close the file.

By default Caddy uses port 2015. If you want to kill the process to stop its execution, type the following.

:~# pkill caddy

Conclusion

Caddy is emerging as a great option to keep in mind, however, it seems that he still has some way to go in the business field.

Thanks to the world of devs, there’s another alternative solution to the problem – Caddy Web Server. It’s a really nice alternative to all those popular choices. It also comes with HTTPS by default, saving a lot of hassle and problem in the start.

Let’s take a look on installing Caddy in our system.

Installing Caddy Web Server

For installing Caddy in our Linux system, we’re going to use cURL. Caddy works the same on all the available platforms including all the normal Linux versions and server editions. It’s because Caddy loves to distribute their software with the help of a specialized bash script instead of adding software repo.

Run the following command:

curl https://getcaddy.com | bash -s personal

In this demo, we’ll be running the Caddy “personal” (free) edition. It’s free of course, but for larger organizations and for higher usage, you should get the commercial edition. However, the commercial one is a bit costly. You can check out the commercial price plans here.

If you want to install the commercial version of Caddy Web Server, run the following command:

curl https://getcaddy.com | bash -s commercial

After the script finishes downloading and installing Caddy, it’ll be installed in /usr/local/bin/ directory. Now, run the following command for modifying the Caddy binary.

sudo setcap cap_net_bind_service=+ep /usr/local/bin/caddy

Configuring Caddy

Now, we have to configure the server. Let’s get going.

Enable root access:

su

OR

sudo -s

Create the directories where Caddy will operate:

mkdir /etc/caddy
mkdir /etc/ssl/caddy
mkdir /var/www

Note that if your server already contains “/var/www/” directory, you can skip the last command.

Now, create a new “Caddyfile”:

touch /etc/caddy/Caddyfile

Update the folder permission of the Caddy sub-folder:

chmod 0770 /etc/ssl/caddy

Now, chown the “/var/www” directory.

chown www-data: /var/www

For working properly with the “systemd”, run the following commands:

touch /lib/systemd/system/caddy.service
nano /lib/systemd/system/caddy.service

Paste the following code into the editor, then “Ctrl + O” to save the file and “Ctrl + X” to close the editor

; The following additional security directives only work with systemd v229 or later.

[Install]
WantedBy=multi-user.target

Restart “caddy.service”:

systemctl enable caddy.service
systemctl start caddy.service

Setting up domains

Now, it’s just normal configuration like most other servers to perform some configurations. Let’s start with the domain folder.

Edit the “Caddyfile” for activating your new domain. Don’t forget to change the names with your domain name.

mkdir -p /var/www/osradar.com/
nano /etc/caddy/Caddyfile

# Paste the following code for activating your domain on Caddy

domain-demo.com {
root /var/www/osradar.com
}

Restart the “caddy.service”:

systemctl restart caddy.service
