How To Install Let’s Encrypt SSL With Lighttpd on CentOS 7

Let’s Encrypt SSL With Lighttpd on CentOS 7

LetsEncrypt is a free open certificate authority (CA) that provides free certificates for websites and other services. The service, which is backed by the Electronic Frontier Foundation, Mozilla, Cisco Systems, and Akamai. Unfortunately, LetsEncrypt.org certificates currently have a 3 month lifetime. This means you’ll need to renew your certificate quarterly for now.

Table of Contents

Step 1. First let’s start by ensuring your system is up-to-date.

Step 2. Installing Let’s Encrypt SSL using Certbot.

Step 3. Configure Lighttpd For Your New Cert.

Step 4. Force HTTPS requests for Lighttpd.

Step 5. Set Up Let’s Encrypt SSL Auto Renewal.

 

 Prerequisites

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Let’s Encrypt SSL with Lighttpd on a CentOS 7 server.
Install Let’s Encrypt SSL With Lighttpd on CentOS 7

Step 1. First let’s start by ensuring your system is up-to-date.

yum clean all
yum -y update

Step 2. Installing Let’s Encrypt SSL using Certbot.

In CentOS 7, you can find Certbot on the EPEL repository; if you enable it, just install what you need:

yum install epel-release
yum install certbo

You will also need to have Lighttpd installed and running. Of course, if you are adding certificates onto a previously configured web host this would already be installed:

yum -y install lighttpd
systemctl start lighttpd.service

Obtaining a certificate with Certbot:

certbot certonly --webroot -w /var/www/wpcademy.com -d wpcademy.com -d www.wpcademy.com

Combine both certificate and private key in one file.

Lighty likes its certificates formatted in a specific way, so we’re going to combine the private keys and certificate into one file that we’ll tell lighty about later:

cat /etc/letsencrypt/live/idroot.us/privkey.pem /etc/letsencrypt/live/wpcademy.com/cert.pem > /etc/letsencrypt/live/idroot.us/combined.pem

Step 3. Configure Lighttpd For Your New Cert.

Configure lighty to use the new certificate and chain:

nano /etc/lighttpd/lighttpd.conf

Use the below information:

$SERVER["socket"] == ":443" {
ssl.engine = "enable"
ssl.pemfile = "/etc/letsencrypt/live/wpcademy.com/web.pem"
ssl.ca-file = "/etc/letsencrypt/live/wpcademy.com/chain.pem"
server.name = "wpcademy.com" 
server.document-root = "/var/www/wpcademy.com"
server.errorlog = "/var/log/lighttpd/wpcademy.com_error.log"
accesslog.filename = "/var/log/lighttpd/wpcademy.com_access.log"

Step 4. Force HTTPS requests for Lighttpd.

We can also configure HTTP to HTTPS redirection on Lighttpd server so that the traffic comes to non-HTTPS site redirect to the HTTPS site:

$HTTP["scheme"] == "http" {
$HTTP["host"] == "wpcadem.com" {
url.redirect = ("/.*" => "https://idroot.us$0")
}
}

Save and close the file when you are finished.

Step 5. Set Up Let’s Encrypt SSL Auto Renewal.

Let’s Encrypt certificates comes with a validity of 90 days; it is highly advisable to configure the cron (Linux Scheduler) job to renew your certificates before they expire:

certbot renew --dry-run

If that appears to be working properly, configure a cron job for the below command:

certbot renew

Congratulation’s! You have successfully installed Let’s Encrypt. Thanks for using this tutorial for installing Let’s Encrypt SSL With Lighttpd on CentOS 7 system. For additional help or useful information, we recommend you to check the official Let’s Encrypt web site.

Virtual Hosts.

Install Caddy Web Server on CentOS 7

Step 1. First let’s start by ensuring your system is up-to-date.

yum clean all
yum -y update

Step 2. Installing Caddy web server on CentOS 7.

Install Caddy is quick and easy with run the following command:

curl https://getcaddy.com | bash

After the script finishes, you can run the following command to see where is your Caddy’s binary file:

which caddy

Your output should be like below:

/usr/local/bin/caddy

Step 3. Setting Up Necessary Directories.

Next, create the directories where we will store the Caddy configuration file Caddyfile and SSL certificates:

mkdir /etc/caddy
chown -R root:caddy /etc/caddy
touch /etc/caddy/Caddyfile
mkdir /etc/ssl/caddy
chown -R caddy:root /etc/ssl/caddy
chmod 0770 /etc/ssl/caddy
mkdir /var/www
chown caddy:caddy /var/www

Step 4. Installing Caddy as a System Service.

We also need to create a new SystemD configuration script:

cd /etc/systemd/system/
nano caddy.service

Add following line:

[Unit]
Description=Caddy HTTP/2 web server
Documentation=https://caddyserver.com/docs
After=network-online.target
Wants=network-online.target systemd-networkd-wait-online.service

[Service]
Restart=on-failure
StartLimitInterval=86400
StartLimitBurst=5

; User and group the process will run as.
User=caddy
Group=caddy

; Letsencrypt-issued certificates will be written to this directory.
Environment=CADDYPATH=/etc/ssl/caddy

; Always set "-root" to something safe in case it gets forgotten in the Caddyfile.
ExecStart=/usr/local/bin/caddy -log stdout -agree=true -conf=/etc/caddy/Caddyfile -root=/var/tmp
ExecReload=/bin/kill -USR1 $MAINPID

; Limit the number of file descriptors; see `man systemd.exec` for more limit settings.
LimitNOFILE=1048576
; Unmodified caddy is not expected to use more than that.
LimitNPROC=64

; Use private /tmp and /var/tmp, which are discarded after caddy stops.
PrivateTmp=true
; Use a minimal /dev
PrivateDevices=true
; Hide /home, /root, and /run/user. Nobody will steal your SSH-keys.
ProtectHome=true
; Make /usr, /boot, /etc and possibly some more folders read-only.
ProtectSystem=full
; … except /etc/ssl/caddy, because we want Letsencrypt-certificates there.
;   This merely retains r/w access rights, it does not add any new. Must still be writable on the host!
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

Set the owner and permissions:

chown root:root /etc/systemd/system/caddy.service
chmod 644 /etc/systemd/system/caddy.service

At last, execute the following commands to enable Caddy to run on boot:

systemctl enable caddy
systemctl start caddy

Step 5. Creating Test Web Page and a Caddyfile.

For testing purposes, we will create a test HTML file:

mkdir -p /var/www/wpcademy.com
echo "Caddy" > /var/www/wpcademy.com/index.html
chown -R www-data: /var/www/my-domain.com

Next, add our domain to the Caddy configuration file:

nano /etc/caddy/Caddyfile

Add following line:

my-domain.com {
    root /var/www/wpcademy.com
}

Save the file and exit the editor. To apply the changes, restart Caddy:

systemctl restart caddy.service

Now, with a web browser, just go to https://wpcademy.com, and you will see our test page!
