Lighttpd is an open-source and lightweight web server released in 2003. It offers high-performance capabilities with low memory and CPU usage, making it ideal for hosting high-traffic websites and applications. It supports multiple platforms and features FastCGI, CGI, SSL/TLS encryption, URL rewriting, virtual hosting, and load balancing. It's widely used by companies like YouTube, Vimeo, and the Wikimedia Foundation for their web applications.This guides will go through how you can install an SSL Certificate on Lighttpd.
- Step 1: Generating a CSR and Private Key
- Step 2: Order and Configure the SSL Certificate
- Step 3: Download and Upload Certificate Files to your Server
- Step 4: Edit the Lighttpd SSL Configuration
- Step 5: Test the SSL Certificate
Prerequisites:-
sudo mkdir /etc/lighttpd/ssl
This will create an ssl directory under lighttpd which will use to store all certificates.
Step 1. Generating a CSR and Private Key with OpenSSL
Open your preferred terminal client as root.
1: Execute the following command to generate a private key and a CSR -
sudo openssl req -new -newkey rsa:2048 -nodes -keyout /etc/lighttpd/ssl/server.key -out /etc/lighttpd/ssl/server.csr
This will create a private key and a CSR with the name of server.key and server.csr respectively; in the lighttpd SSL Directory.
You will then get a prompt asking you to input the following details regarding your CSR:-
Country Name (2 letter code) [AU]: Type in the 2 letter abbreviation for your country.
State or Province Name (full name) [Some-State]: Full name of the state
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Locality Name (eg, city) []: Complete name of the city, no abbreviations
Organization Name (eg, company) [Internet Widgits Pty Ltd]: If you are a business; Enter your legal entity name. If you're not a business, any value entered will not be used in your certificate.
Organizational Unit Name (eg, section) []: If you are a business; Write the appropriate division of your company. It is best to use something generic such as "IT".
Common Name (e.g. server FQDN or YOUR name) []: Enter your domain name
Email Address []: Enter your email address
After you hit Enter, your Private Key and CSR should be saved successfully in the Lighttpd SSL directory.
2: To view your CSR, type in the following command:
sudo cat /etc/lighttpd/ssl/server.csr
You can save the CSR and Private Key in a .txt file for further configuration.
Step 2. Order and Configure the SSL Certificate
The next step in the installation process is to order an SSL Certificate. We recommend SSLTrust because of our exceptional Customer Service, Money Back guarantee and SSL Installation Service.
If you have one website, you can now secure one domain name from a variety of cheap, easy and fast to implement SSL Certificates.
However, if you are a business website, we recommend getting a Business SSL because it gives your visitors the complete level of trust which includes a Site Seal and validation by a Certificate Authority (CA). You might want to have a look at getting GeoTrust SSL such as the True Business SSL.
Additonally, if you have multiple subdomains, it might be worthwile to check out Wildcard SSL Certificates because you can get all of your subdomains verified in just one go and elimates the need of purchasing multiple SSL Certificates.
If you need help choosing the right SSL Certificate, our sales/support team is here to help. Just reach out to them, and they'll be glad to offer their assistance.
1: Once you've added the SSL Certificate into your cart, you can now click on Checkout to complete the process.
Fill in your account details
Choose your preferred mode of payment and click on checkout.
2: After you have purchased the SSL Certificate, you can start the configuration process.
This can be started by going into your SSLTrust account and managing your recent purchase.
Head over to the SSLTrust Dashboard and under Services, select My Services.
You should be able to see your purchased certificate and order status, now click on Manage
This will take you to the Product Details of your SSL Certificate. Click on start configuration to do the configuration yourself or you can provide the URL below to the appropriate person to complete the configuration for you.
3: Copy and paste the previously generated CSR (Certificate Signing Request) which should include:-
-----BEGIN CERTIFICATE REQUEST----- -----END CERTIFICATE REQUEST-----
Then, click on Verify CSR.
If the CSR details match the inputs you've entered before, you can now proceed or else generate a new CSR with proper details.
Select the Server Type and click on Next Step>
4: Fill in your contact information
If you have a technical contact managing the certificate for you, please enter their details.
They will also have permission to manage the Certificate and will be sent renewal reminders.
To obtain a business SSL certificate, you will need to provide your business details, including your correct address, phone number, and legal entity name. The Certificate Authority will verify the accuracy of this information. If there are any mistakes, it may cause delays in the process.
Then, click on Next Step>
5: The next step in this process is Domain Control Validation (DCV). Basically, Domain control validation is a process used to verify that the person or organization requesting an SSL/TLS certificate for a domain has the authority to control that domain. There are several different methods that can be used to perform DCV, including email validation, DNS validation, and file-based validation.
Select the method that is easiest for you. Having an email address with the domain name will be the quickest.
You will be sent an email containing a link which when clicked upon should validate your domain name.
In HTTP/HTTPS File Validation Method, you can create a folder in the specified and directory, paste in the contents and your domain should be validated.
The final method to validate your domain name would be CNAME Validation. Basically you have to create a CNAME record in your DNS Settings to validate your domain name and then click on the Check DNS Record button to verify DNS changes.
After a few seconds or minutes depending on your DNS propagation speed, the CNAME record should be verified.
The configuration should be a success. Click on the button below to access the validation manager.
6: Your certificate should have now been issued if you completed all the above steps correctly.
If not, click on Domain Control Validation, and re-submit whatever method you chose for validation.
Upon completing domain validation using the chosen method, your SSL certificate will be issued. If you have ordered a Business SSL, you will need to wait for the Certificate Authority to verify your business address and phone number. If the validation process has not been completed or you have not received your certificate after a certain period of time, please reach out to the support team to check on the status of your certificate.
Step 3. Download and Upload Certificate Files to your Server
Once your SSL certificate has been issued, you will receive an email with the certificate directly from the Certificate Authority. Alternatively, you can download the certificate from the SSLTrust Portal, which presents the certificate in a convenient, easy-to-use format.
Again, head over to the SSLTrust Dashboard and click on your certificate:-
1: Click on Collect/Download Certificate-
2: Go to the first column and click on copy to clipboard
3: Create a new file with the command below and paste the copied SSL Certificate.
sudo nano /etc/lighttpd/ssl/certificate.crt
4: Again, head back to the certificate collection page and click on copy to clipboard on the Intermediate certificate.
5: Create a new file with the command below and paste the copied Intermediate SSL Certificate.
sudo nano /etc/lighttpd/ssl/intermediate.crt
Note:- As per lighttpd's SSL documentation, both the private key and the main certificate should be in one file. So we will concatenate both of them with the next command.
6: Concatenate the private key and the main certificate
sudo cat server.key certificate.crt > certificate.pem
Step 4. Edit the Lighttpd SSL Configuration
1: Navigate to the Lighttpd SSL Configuration
sudo nano /etc/lighttpd/lighttpd.conf
2: Make/add the following changes
$SERVER["socket"] == ":443"{
ssl.engine = "enable"
ssl.pemfile = "/etc/lighttpd/ssl/certificate.pem"
ssl.ca-file = "/etc/lighttpd/ssl/intermediate.crt"
server.name = "yourdomain.com"
server.document-root = "/var/ww/html"
}
Step 5. Test the SSL Certificate
It is a good idea to go to your website and see if it works via https://www.yourdomain.com We also recommend you use this tool to check the install has been completed successfully: www.ssllabs.com/ssltest/
For custom port/Localhost SSL Testing, check out another tool here
You may need to get your web developer, or update your website yourself, to make sure all files use https:// and all links to your site and within your website use https://
