First, you need to generate CSR to apply for non-1 certificates. It is very important to remember to save the. key file when generating CSR. This file is required for subsequent certificate deployment You can create a new txt file to copy the content, and then save it. Later, you can modify the file suffix to. key file. Build tool: 1、 Online CSR generation tool 2、 Linux server generation After generation, you need to add the generated CSR content to the website for certificate review and issuance. At this time, you will receive an authorization email that requires authorization. Enter the email (titled "Action Required") and click the link to complete authorization. After the authorization is completed and successfully signed and issued, an email titled "Compile xxxxx" will be received. There is a string of ciphertext in the email, which is what we need Open link: Certificate composition tool Click the tool to go in and select "PEM file including certificate (CRT/CER)", enter the ciphertext in the email in the input box below, and then click the composite pem file below. (The pem file is the crt file). Then copy the generated ciphertext and save it as a file. The file suffix is the end of crt. The certificate can be deployed later by using this file and the private key file at the end of. key. Refer to the following documents for deployment: Ngnix Deployment Certificate Apache deployment certificate |
