How to generate a CSR code on Apache?
The Certificate Signing Request, or simply CSR, is a small text file containing information about your domain ownership and/or company. Generating CSR is an integral part of the SSL buying process. All commercial Certificate Authorities require SSL applicants to complete this step.
You have two options:
- Generate the CSR automatically using our CSR Generator.
- Follow our step-by-step tutorial on how to create the CSR on Apache.
Install an SSL Certificate on Apache
After the Certificate Authority signs and sends you the SSL Certificate, you can safely install it on your Apache server.
Step 1: Prepare all your certificate files
Download and extract the following files from the zip folder that you’ve received from your CA:
- .crt file – this is your primary SSL certificate
- .ca-bundle file – inside are the root and intermediate certificates. The chain of intermediate and root certificates is required for older browsers and applications. Without it, your site may be flagged as not secure
Note: If you Ca bundle certificates are in separate files, upload them to your server and use the following command to create a single CA bundle file:
cat COMODORSADomainValidationSecureServerCA.crt COMODORSAAddTrustCA.crt AddTrustExternalCARoot.crt >> bundle.crt
The example above is for Sectigo PositiveSSL certificate.
Step 2: Find the Apache configuration file to edit.
Depending on the server and OS version, the config file may reside in different directories. Look for httpd.conf, apahce2.conf or ssl.conf in one of the following directories: etc/httpd/, /etc/apache2/ or /etc/httpd/conf.d/ssl.conf
Note: If your Apache server is running on Ubuntu OS, please follow our SSL installation instructions for Ubuntu instead.
Step 3: Configure the virtual host section
Once you’ve located the Apache configuration file, you have to configure the virtual host section of your site.
First, back up your current *.conf file. This way, if something goes wrong, you will be able to undo the changes.
Tip: copy the existing *.conf file and rename it to *.conf_backup
Now, it’s time to edit the Virtual Host. A typical Virtual Host looks like this:
ServerAdmin [email protected]
The part highlighted in bold is the one you have to edit with your corresponding details
Make sure the attributes in bold don’t have a ‘#’ (comment) in front of them; otherwise, please uncomment them
Change the file names to match your certificate files and their location on the server:
- SSLCertificateFile: this is your primary SSL certificate file
- SSLCertificateKeyFile: this is your private key file. You’ve generated it along with the CSR code
- SSLCertificateChainFile: this is your CA Bundle file
Step 4: Save your Apache configuration file and restart your server.
To restart Apache run one of the commands below:
If something goes wrong, or Apache fails to restart, don’t panic! Remember, you created a backup configuration file in step 3. All you have to do is delete the modified configuration file, revert to your backup and repeat the installation process.
If the installation was successful, congratulations! Your website is now secure.

1. What is SSL in Apache?
SSL (Secure Sockets Layer), now TLS (Transport Layer Security), is a cryptographic protocol that encrypts communications between two network endpoints, for instance, a web server such as Apache and users’ browsers.
2. How do I know if Apache SSL is enabled?
For Debian and Ubuntu distributions, use the following commands
#grep -ir SSLProtocol /etc/apache2/*
/etc/apache2/mods-available/ssl.conf:SSLProtocol +TLSv1.2 +TLSv1.3
3. Where is the SSL .conf file in Apache?
The conf. file may reside in different locations depending on your OS and configuration. Check the httpd.conf, apahce2.conf or ssl.conf in one of the following directories: etc/httpd/, /etc/apache2/ or /etc/httpd/conf.d/ssl.conf.
