LiteSpeed Web Server is a high-performance HTTP server that is designed to handle large amounts of traffic and provide fast response times for web applications. It is optimized for speed and security, and offers a range of features to help administrators improve the performance and security of their web server. Some of the key features of LiteSpeed Web Server include native support for SSL and HTTP/2, advanced caching capabilities, and easy integration with popular web applications. Moreover, it is the 4th most popular web server, estimated to be used by 10% of websites as of July 2021. LSWS is developed by privately held LiteSpeed Technologies. This guide will go through how you can successfully install an ssl certificate and secure your website/s.

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 /usr/local/lsws/server.key -out /usr/local/lsws/server.csr

This will create a private key and a CSR with the name of server.key and server.csr respectively; in the default Litespeed
installation 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 default litespeed directory.

2: To view your CSR, type in the following command:

sudo cat /usr/local/lsws/server.csr

You can save the CSR in a .txt file or directly proceed to certificate 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.

4: Fill in your contact information

Contact Info

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.

Technical Contact

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.

domain control 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.

HTTP Method

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.

CNAME Method

After a few seconds or minutes depending on your DNS propagation speed, the CNAME record should be verified.

DNS Check

The configuration should be a success. Click on the button below to access the validation manager.

Certificate Issue Success

6: Your certificate should have now been issued if you completed all the above steps correctly.

Certificate Issue Success

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 your SSL Certificate/s and Upload to Litespeed Webserver

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.

2: Now, head back to the certificate collection page and click on copy to clipboard on the Intermediate certificate.

Copy Intermediate SSL Certificate

Now, execute the following command

sudo nano /usr/local/lsws/intermediate.crt

Paste in your intermediate certificate, press CTRL+X to save and exit the buffer.
