Generate a CSR code on Sentora

To create your CSR (Certificate Signing Request) code on Sentora, perform the following:

  1. Run the sudo –i command to login to a terminal as the root user
  2. If you don’t have the OpenSSL utility, install it via apt-get install openssl
  3. Next, create a directory for your certificates: mkdir /etc/apache2/ssl/
  4. Enter the following command to generate your CSR code and private key
    openssl req -new -newkey rsa:2048 -nodes -keyout yourdomain.key -out yourdomain.csr

    Note: Don’t forget to replace yourdomain with your real domain name. For example, if your domain name is, you must type yoursite.key and yoursite.csr.

  5. You’ll be prompted to provide your contact details. Please use the examples below:
    • Country Name (2 letter code): enter the official two-letter code of your country. For instance, US
    • State or Province Name: write the full name of the state where your company is registered. For example, Washington
    • Locality Name: write the full name of the city where your company is located. For instance, Seattle
    • Organization Name: specify the full legal name of your organization. For example, Your Company LLC
    • Organizational Unit Name: enter the department in charge of your SSL Certificate. For example, Web Administration
    • Common Name: provide the FQDN (fully-qualified domain name) you want to secure. For example,
  6. The OpenSSL utility will generate your CSR and private key files. You can run the ls command to locate them in your working directory
  7. Open the CSR file with any text editor of your choice such as Notepad, and copy its contents including the —–BEGIN CERTIFICATE—– and —–END CERTIFICATE—– tags into the corresponding box during the SSL order process.
  8. Wait for the SSL Certificate to arrive in your inbox.

Install an SSL Certificate on Sentora

After your CA sends the necessary files to your inbox, download the ZIP folder and extract its contents on your device.

Prepare your SSL files for installation:

You should receive three files from your CA:

  • Your server SSL Certificate (domain_com.crt)
  • Your CA root certificate (CaRoot.crt)
  • Your Intermediate CA certificate (the name will vary depending on your SSL provider).

Note: Some CAs will send you the CA Bundle file containing both root and intermediate certificates. In this case, disregard the next step.

If you received the Root and Intermediate certificates in separate files, you need to merge them in a single plain text document.

Open a text editor of your choice such as Notepad and copy-paste the code from your Root certificate file, followed by the code from your Intermediate certificate. Make sure you don’t leave any blanks spaces.

Save the file and name it

You will also need your CSR file (domain_com.csr).

Install your SSL Certificate

  1. Run the sudo or su commands to login as root user in a terminal
  2. If the SSL isn’t activated on your server, run a2enmod ssl
  3. Restart Apache via service apache2 restart
  4. Create the links required for mods:
    • ln -s /etc/apache2/mods-available/ssl.conf /etc/apache2/mods-enabled/ssl.conf
    • ln -s /etc/apache2/mods-available/ssl.load /etc/apache2/mods-enabled/ssl.load
  5. Navigate to Sentora > Admin > Module Admin > Apache Admin
  6. Copy and paste the following code into Global Sentora entry:
    # Apache VHOST configuration file
    # Customised entries for Sentora
    NameVirtualHost *:443
    # Configuration for Sentora control panel.
