openssl - How to configure nginx to configure SSL security certificate and restart without entering password

Question

Today I configured an SSL security certificate for Nginx

ssl on; 
    ssl_certificate  /home/cert/server.crt;
    ssl_certificate_key  /home/cert/server.key;

Then the password will be required when restarting and reloading. . .

# /usr/local/nginx/sbin/nginx -s reload
Enter PEM pass phrase:

But I have a script that needs to run reload every day, and the password input function cannot be implemented
Is there any way to automatically enter the password?

P.S. I tried the pipe, but nginx couldn’t receive it

Answer 1

You can do this with a private key. Generate a decrypted key file to replace the original key file.

openssl rsa -in server.key -out server.key.unsecure

Then modify the configuration file

ssl on; 
    ssl_certificate  /home/cert/server.crt;
    ssl_certificate_key  /home/cert/server.key.unsecure;

This way you don’t have to enter your password

Answer 2

Try the expect command, which can be used to enter the password. You can refer to the expect automatic ssh script.
