The CSR is to be sent to the certificate authority for validation and signing immediately after the certificate activation in the Namecheap user account panel. The private key must be kept secret, ideally on the same server the certificate will be installed on. Can I generate a new private key. Generating a Certificate Signing Request (CSR) for Secure Sockets Layer (SSL) Certificate in Linux are common on most of the Linux distributions. In case if we need a certificate for Apache service facing internet or an Internal FTP server in your organization required a secure file transfer by eliminating plain text transfer on your network. You can generate an SSH key pair directly in cPanel, or you can generate the keys yourself and just upload the public one in cPanel to use with your hosting account. When generating SSH keys yourself under Linux, you can use the ssh-keygen command. To do so follow these steps: Open up the Terminal.
CSR stands for ‘Certificate Signing Request’, that is generated on the server where the certificate will be used on. A CSR contains information about to your organization and domain name, locality, and country and a public key that will be included in your certificate.
This article has 3 methods to create CSR (Certificate Signing Request) on Linux systems. Generate ssh keys linux server. You can choose any one of below methods. All methods will do the same task, only they have a detailed explanation.
Method 1 – Using Single Command
We can create CSR using the single command like below. But make sure you have installed OpenSSL package on your system. The below command will first create a private key and then generate CSR. This command will also require few details as input.

Method 2 – Short Instructions
Below are three simple commands to generate CSR. You may also use detailed instructions to do it.
Method 3 – Detailed Instructions
Step 1: Install Required Packages.
In order to generate CSR, you required OpenSSL to be installed on your system. If it is not already installed use below command to install it.
Step 2: Generate Key for your Domain.
Firstly you required root access to generate a key file. So login as root and use below command to generate a key.
Openssl Generate Key And Csr In Linux
Sample output:
At the end of the command, it showing 2048, which is the length of the key in bits. Most of CA required 2048 bit length keys. Above command will create a key file tecadmin.net.key, which is used in step 3.
Step 3: Generate CSR for your Domain using Key.
After generating a key, next steps are to generate CSR for the domain. Use below command to generate CSR file, This command will prompt for your organization and common name, locality, email, and country. Common Name must be the same as your domain name.
Sample Output:
Generate Csr Linux
Above command will generate a file tecadmin.net.csr in the current directory, Use this file to order your SSL from CA (Certificate Authority).
