In this tutorial we will show you how to install Caddy on Ubuntu 16.04. We will also install and configure its prerequisites. Caddy is an open source HTTP Web server Which Employed for various platforms Such as Windows, Mac, Linux, FreeBSD, OpenBSD, etc.. It is a full Featured HTTP/2 web server which may be automatically enables that the HTTPS. It allows the designers to do amazing things with high flexibility and low overhead.
I recommend to use a minimal Ubuntu server setup as a basis for the tutorial, that can be a virtual or a root server image with an Ubuntu 16.04 minimal install from a web hosting company or you use our minimal server tutorial to install a server from scratch.
Install Caddy on Ubuntu 16.04
Step 1. First, ensure your system and apt package lists are fully up-to-date by running the following:
apt-get update -y apt-get upgrade -y
Step 2. Installing Caddy.
Execute the following command:
curl https://getcaddy.com | bash
After the script finishes, the Caddy binaries are installed on the server and ready to use. You can verify that Caddy binaries have been put in place by using which to check their location:
Your output should be like below:
Step 3. Configure Caddy.
First of all, create a directory that will contain the main Caddyfile:
sudo mkdir /etc/caddy sudo chown -R root:www-data /etc/caddy sudo mkdir /etc/ssl/caddy sudo chown -R www-data:root /etc/ssl/caddy sudo chmod 0770 /etc/ssl/caddy sudo touch /etc/caddy/Caddyfile sudo mkdir /var/www sudo chown www-data: /var/www
Step 4. SystemD Configuration
We also need to create a new SystemD configuration script:
Paste the following configuration then save and exit:
[Unit] Description=Caddy HTTP/2 web server Documentation=https://caddyserver.com/docs After=network-online.target Wants=network-online.target [Service] Restart=on-failure StartLimitInterval=86400 StartLimitBurst=5 User=www-data Group=www-data ; Letsencrypt-issued certificates will be written to this directory. Environment=CADDYPATH=/etc/ssl/caddy ExecStart=/usr/local/bin/caddy -log stdout -agree=true -conf=/etc/caddy/Caddyfile -root=/var/tmp ExecReload=/bin/kill -USR1 $MAINPID LimitNOFILE=1048576 LimitNPROC=64 PrivateTmp=true PrivateDevices=true ProtectHome=true ProtectSystem=full ReadWriteDirectories=/etc/ssl/caddy ; The following additional security directives only work with systemd v229 or later. ; They further retrict privileges that can be gained by caddy. Uncomment if you like. ; Note that you may have to add capabilities required by any plugins in use. ;CapabilityBoundingSet=CAP_NET_BIND_SERVICE ;AmbientCapabilities=CAP_NET_BIND_SERVICE ;NoNewPrivileges=true [Install] WantedBy=multi-user.target
Start the Caddy service and make it automatically start on system boot:
sudo systemctl daemon-reload sudo systemctl start caddy.service sudo systemctl enable caddy.service
Step 4. Create simple test configuration of Caddy.
Use the following command to create a file named index.html in your Caddy site home directory:
echo '<h1>Hello World!</h1>' | sudo tee /var/www/example.com/index.html
Restart the Caddy service to load new contents:
sudo systemctl restart caddy.service
Finally, point your web browser to http://example.com or https://example.com. You should see the message Hello World! as expected.
