Most hosting control panel provide GUI for generating CSR.

If you are on a server with no control panel, you can generate CSR on any Linux computer by running

openssl req -new -newkey rsa:2048 -nodes -out domain-name.csr -keyout domain-name.key -subj "/C=COUNTRY-CODE-HERE-2-LETTER/ST=STATE-HERE/L=CITY-HERE/O=BUSINESS-NAME-HERE/OU=Retail/CN=domain-name"

If you want OpenSSL ask for information, run following command.

openssl req -new -newkey rsa:2048 -nodes -keyout domain-name.key -out domain-name.csr

Example

boby@hon-pc-01:~ $ openssl req -new -newkey rsa:2048 -nodes -keyout hostonnet.com.key -out hostonnet.com.csr
