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
