A blank page. Visits to webpages are also prompts. Skip the prompt to continue visiting, the page is normal. So it's not the system that went wrong. The certificate has expired.

Chief, give me a certificate and compress the package. It's this after decompression.

So where should I put this? Do you want to modify the public address number? Obviously not, because the webpage version also prompted errors. Then it's only to modify the server.

[root@clue360 sbin]# /usr/sbin/nginx -s reload

ps -ef|grep nginx	See if the current server is nginx, obviously. The command is / usr/sbin/nginx
nginx -V	It's a command above, but it's not the installation directory of nginx, so this is to look at the installation directory. The configuration file is in -- conf-path=/etc/nginx/nginx.conf So nginx is in / ect/nginx
/usr/sbin/nginx -s reload	This is the nginx restart command. You can restart after replacing the certificate.

The two files nginx, and the two files in the certificate given, look like ah. Here it is. Replace these two files with ok. Note that the names must be the same. Dissimilarity. You will be prompted to do the same when you restart. Ha-ha.
