How does nginx replace the SSL certificate?

 

---

1. Find the main nginx configuration file nginx.conf

  Example:

[root@shuaishuai ~]# find / -name nginx.conf

2.切换目录

  Example:

[root@shuaishuai ~]# cd /usr/local/nginx/conf/nginx.conf

 3.vim edit the main configuration file nginx.conf to find out the configuration path of the certificate

   Example:

[root@shuaishuai conf]# vim nginx.conf

4. Switch to the directory where the certificate file is located

   Example:

[root@shuaishuai conf]# cd /usr/local/nginx/conf/cert
[root@shuaishuai cert]# ls

5. Back up the old certificate and upload the new one

   Example:

[root@shuaishuai cert]# mv www.shuaijun.vip.pem www.shuaijun.vip.pem.bak
[root@shuaishuai cert]# mv www.shuaijun.vip.key www.shuaijun.vip.key.bak

6. Rename the uploaded new certificate name to the name of the old certificate

   Example:

[root@shuaishuai cert]# mv 123.www.shuaijun.vip.pem www.shuaijun.vip.pem
[root@shuaishuai cert]# mv 123.www.shuaijun.vip.key www.shuaijun.vip.key

 7. Check the configuration file and restart the nginx service

   Example:

[root@shuaishuai cert]# nginx -t
[root@shuaishuai cert]# killall -1 nginx
