How to Install Caddy with PHP & HTTPS using Let’s Encrypt on Ubuntu

Install Caddy with PHP & HTTPS using Let’sEncrypt on Ubuntu. In this guide you are going to learn how to install Caddy with PHP 7.4 and also configure HTTPs on Ubuntu 18.04.

Caddy is a open source web server with automatic HTTPS written in Go language. It takes care of TLS certificate renewals, OCSP stapling, static file serving, reverse proxying, and more.

This tutorial is tested on Google Cloud and AWS, so it works fine on other cloud services like Azure, DigitalOcean or any VPS or any Dedicated servers running Ubuntu.

If you are on Google Cloud you should follow the below listed prerequisites.

Prerequisites for Google Cloud

1. Your Compute Engine Instance running.
2. For setting up Compute Engine, see the Setting up Compute Engine Instance.
3. Set up Cloud DNS, see the Setting up Google Cloud DNS for your domain.

If you are on AWS you should follow these below listed prerequisites.

Prerequisites for AWS

1. A running EC2 Instance. Learn how to create an AWS EC2 instance.
2. Assigned a Elastic IP to your EC2 Instance.
3. Setup and configure Route 53 and point your domain to AWS.
4. Successful SSH connection to your EC2 Instance.

SSH to your EC2 Instance and perform the steps listed below.

Initial Server Setup

Let’s start by updating the local package index with the following command to the latest available version.

sudo apt update
sudo apt upgrade

Once the update is done you can start the installation of Caddy.

Install Caddy

Once you have your server setup and domain name pointed to your server you can proceed to install Caddy.

Execute the following commands to install Caddy.

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

Once the installation is completed you will get an output similar to the one below.

Output
Putting caddy in /usr/local/bin (may require password)
Caddy v1.0.4 (h1:wwuGSkUHo6RZ3oMpeTt7J09WBB87X5o+IZN4dKehcQE=)
Successfully installed

This output shows Caddy is installed in /usr/local/bin.

You can check the version of Caddy installed using this command.

caddy -version

Configure Caddy

Now you need to allow Caddy binary to bind to ports 80 and 443.

Setup directories for Caddy.

sudo mkdir /etc/caddy
sudo mkdir /etc/ssl/caddy 
sudo mkdir /var/log/caddy 

Configure correct permissions.

sudo chown -R root:root /etc/caddy
sudo chown -R root:www-data /etc/ssl/caddy
sudo chown -R root:www-data /var/log/caddy 
sudo chmod 0770 /etc/ssl/caddy

Configure Caddy Systemd service unit

Now you can create a systemd service file for Caddy which is available in the official repository and reload the demon for the changes to be available.

wget https://raw.githubusercontent.com/caddyserver/caddy/master/dist/init/linux-systemd/caddy.service
sudo cp caddy.service /etc/systemd/system/
sudo chown root:root /etc/systemd/system/caddy.service
sudo chmod 644 /etc/systemd/system/caddy.service
sudo systemctl daemon-reload

Install PHP 7.4 FPM

Add the ondrej/php which has PHP 7.4 FPM package and other required PHP extensions.

sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php -y
sudo apt update

Install PHP 7.4 and some common extensions.

sudo apt install php7.4-fpm php7.4-common php7.4-mysql php7.4-xml php7.4-xmlrpc php7.4-curl php7.4-gd php7.4-imagick php7.4-cli php7.4-dev php7.4-imap php7.4-mbstring php7.4-opcache php7.4-soap php7.4-zip php7.4-intl php7.4-bcmath unzip -y

Once PHP 7.4 FPM is installed you can configure your domain name with Caddy.

Configure Domain and Webroot in Caddy

Create a new directory for your website files and configure correct permissions.

sudo mkdir /var/www
sudo chown www-data:www-data /var/www
sudo nano /var/www/index.html

Create a Caddy file named Caddyfile inside /etc/caddy/ and configure your domain name with HTTPS.

sudo nano /etc/caddy/Caddyfile

Copy the below configuration and paste it inside this file.

https://domain.com {
     root /var/www/

     log /var/log/caddy/domain.log

     tls on
     gzip

     fastcgi / /run/php/php7.4-fpm.sock {
         ext .php
         split .php
         index index.php
     }
}

Hit CTRL + X followed by Y and ENTER to save and exit the file.

Restart/Start Caddy to have the changes available and Let’s Encrypt configured automatically.

sudo service caddy start

If you have your Caddy server started before you can restart using the following command.

sudo service caddy restart

Now you can check the status of Caddy using the following command.

sudo service caddy status

You should see an output similar to the one below.

Output
● caddy.service - Caddy HTTP/2 web server
    Loaded: loaded (/etc/systemd/system/caddy.service; disabled; vendor preset: enabled)

            └─24533 /usr/local/bin/caddy -log stdout -log-timestamps=false -agree=true -conf=/etc/caddy/Caddyfile -root=/var/tmp

If you get any error about Certificate Maintenance or JSON parse, you can try the following steps listed below. If you are fine you can skip it.

sudo rm -rf /etc/ssl/caddy*

Setup Test PHP file

Create a new file to output the installed PHP information.

sudo nano /var/www/index.php

Enter the following code inside it and save the file.

<?php phpinfo();

Verify the Caddy Setup

Once you have restarted Caddy and completed all the setups listed above you can check your domain in your web browser.

You should see the PHP information and your domain loaded with HTTPS.

Prepare yourself for a role working as an Information Technology Professional with Linux operating system

Pdf2gerb: Perl Script Converts PDF Files to Gerber format

pdf2gerb

Perl script converts PDF files to Gerber format

Pdf2Gerb generates Gerber 274X photoplotting and Excellon drill files from PDFs of a PCB. Up to three PDFs are used: the top copper layer, the bottom copper layer (for 2-sided PCBs), and an optional silk screen layer. The PDFs can be created directly from any PDF drawing software, or a PDF print driver can be used to capture the Print output if the drawing software does not directly support output to PDF.

The general workflow is as follows:

1. Design the PCB using your favorite CAD or drawing software.
2. Print the top and bottom copper and top silk screen layers to a PDF file.
3. Run Pdf2Gerb on the PDFs to create Gerber and Excellon files.
4. Use a Gerber viewer to double-check the output against the original PCB design.
5. Make adjustments as needed.
6. Submit the files to a PCB manufacturer.

Please note that Pdf2Gerb does NOT perform DRC (Design Rule Checks), as these will vary according to individual PCB manufacturer conventions and capabilities. Also note that Pdf2Gerb is not perfect, so the output files must always be checked before submitting them. As of version 1.6, Pdf2Gerb supports most PCB elements, such as round and square pads, round holes, traces, SMD pads, ground planes, no-fill areas, and panelization. However, because it interprets the graphical output of a Print function, there are limitations in what it can recognize (or there may be bugs).

See docs/Pdf2Gerb.pdf for install/setup, config, usage, and other info.

Once PHP 7.4 FPM is installed you can configure your domain name with Caddy.

Configure Domain and Webroot in Caddy

Create a new directory for your website files and configure correct permissions.

sudo mkdir /var/www
sudo chown www-data:www-data /var/www
sudo nano /var/www/index.html

Create a Caddy file named Caddyfile inside /etc/caddy/ and configure your domain name with HTTPS.

sudo nano /etc/caddy/Caddyfile

Copy the below configuration and paste it inside this file.

https://domain.com {
     root /var/www/

     log /var/log/caddy/domain.log

     tls on
     gzip

     fastcgi / /run/php/php7.4-fpm.sock {
         ext .php
         split .php
         index index.php
     }
}

Hit CTRL + X followed by Y and ENTER to save and exit the file.

Restart/Start Caddy to have the changes available and Let’s Encrypt configured automatically.

How to Install Caddy with PHP & HTTPS using Let’s Encrypt on Ubuntu

Install Caddy with PHP & HTTPS using Let’sEncrypt on Ubuntu. In this guide you are going to learn how to install Caddy with PHP 7.4 and also configure HTTPs on Ubuntu 18.04.

Caddy is a open source web server with automatic HTTPS written in Go language. It takes care of TLS certificate renewals, OCSP stapling, static file serving, reverse proxying, and more.

This tutorial is tested on Google Cloud and AWS, so it works fine on other cloud services like Azure, DigitalOcean or any VPS or any Dedicated servers running Ubuntu.

If you are on Google Cloud you should follow the below listed prerequisites.

Prerequisites for Google Cloud

1. Your Compute Engine Instance running.
2. For setting up Compute Engine, see the Setting up Compute Engine Instance.
3. Set up Cloud DNS, see the Setting up Google Cloud DNS for your domain.

If you are on AWS you should follow these below listed prerequisites.

Prerequisites for AWS

1. A running EC2 Instance. Learn how to create an AWS EC2 instance.
2. Assigned a Elastic IP to your EC2 Instance.
3. Setup and configure Route 53 and point your domain to AWS.
4. Successful SSH connection to your EC2 Instance.

SSH to your EC2 Instance and perform the steps listed below.

Initial Server Setup

Let’s start by updating the local package index with the following command to the latest available version.

sudo apt update
sudo apt upgrade

Once the update is done you can start the installation of Caddy.

Install Caddy

Once you have your server setup and domain name pointed to your server you can proceed to install Caddy.

Execute the following commands to install Caddy.

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

Once the installation is completed you will get an output similar to the one below.

Output
Putting caddy in /usr/local/bin (may require password)
Caddy v1.0.4 (h1:wwuGSkUHo6RZ3oMpeTt7J09WBB87X5o+IZN4dKehcQE=)
Successfully installed

This output shows Caddy is installed in /usr/local/bin.

You can check the version of Caddy installed using this command.

caddy -version

Configure Caddy

Now you need to allow Caddy binary to bind to ports 80 and 443.

Setup directories for Caddy.

sudo mkdir /etc/caddy
sudo mkdir /etc/ssl/caddy 
sudo mkdir /var/log/caddy 

Configure correct permissions.

sudo chown -R root:root /etc/caddy
sudo chown -R root:www-data /etc/ssl/caddy
sudo chown -R root:www-data /var/log/caddy 
sudo chmod 0770 /etc/ssl/caddy

Configure Caddy Systemd service unit

Now you can create a systemd service file for Caddy which is available in the official repository and reload the demon for the changes to be available.

wget https://raw.githubusercontent.com/caddyserver/caddy/master/dist/init/linux-systemd/caddy.service
sudo cp caddy.service /etc/systemd/system/
sudo chown root:root /etc/systemd/system/caddy.service
sudo chmod 644 /etc/systemd/system/caddy.service
sudo systemctl daemon-reload

Install PHP 7.4 FPM

Add the ondrej/php which has PHP 7.4 FPM package and other required PHP extensions.

sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php -y
sudo apt update

Install PHP 7.4 and some common extensions.

sudo apt install php7.4-fpm php7.4-common php7.4-mysql php7.4-xml php7.4-xmlrpc php7.4-curl php7.4-gd php7.4-imagick php7.4-cli php7.4-dev php7.4-imap php7.4-mbstring php7.4-opcache php7.4-soap php7.4-zip php7.4-intl php7.4-bcmath unzip -y

Once PHP 7.4 FPM is installed you can configure your domain name with Caddy.

Configure Domain and Webroot in Caddy

Create a new directory for your website files and configure correct permissions.

sudo mkdir /var/www
sudo chown www-data:www-data /var/www
sudo nano /var/www/index.html

Create a Caddy file named Caddyfile inside /etc/caddy/ and configure your domain name with HTTPS.

sudo nano /etc/caddy/Caddyfile

Copy the below configuration and paste it inside this file.

https://domain.com {
     root /var/www/

     log /var/log/caddy/domain.log

     tls on
     gzip

     fastcgi / /run/php/php7.4-fpm.sock {
         ext .php
         split .php
         index index.php
     }
}

Hit CTRL + X followed by Y and ENTER to save and exit the file.

Restart/Start Caddy to have the changes available and Let’s Encrypt configured automatically.

sudo service caddy start

If you have your Caddy server started before you can restart using the following command.

sudo service caddy restart

Now you can check the status of Caddy using the following command.

sudo service caddy status

You should see an output similar to the one below.

Output
● caddy.service - Caddy HTTP/2 web server
    Loaded: loaded (/etc/systemd/system/caddy.service; disabled; vendor preset: enabled)

Create a new file to output the installed PHP information.

sudo nano /var/www/index.php

Enter the following code inside it and save the file.
