Let’s Encrypt/Certbot移除/remove/revoke不需要的域名证书

1.首先确认你的证书不再需要，如果有必要，请执行下面的命令进行备份

cp /etc/letsencrypt/ /etc/letsencrypt.backup -r

2.撤销证书然后删除证书

[root@localhost certbot-0.34.2]# certbot revoke    ####这个是撤销命令，执行这命令下面会报错要让我指定变量位置

[root@localhost certbot-0.34.2]# certbot revoke --cert-path /etc/letsencrypt/archive/pazzn.com/c
cert1.pem   cert2.pem   chain1.pem  chain2.pem
[root@localhost certbot-0.34.2]# certbot revoke --cert-path /etc/letsencrypt/archive/pazzn.com/cert
cert1.pem  cert2.pem
[root@localhost certbot-0.34.2]# certbot revoke --cert-path /etc/letsencrypt/archive/pazzn.com/cert1.pem  ###撤销这个cert1.pem证书，一般默认都是我这个位置

3.弄完证书后还得删除在nginx.conf配置文件中的ssl配置内容，不然没有了证书，一般就报404什么的了，所以一定要删除

删除后记得重启nginx服务，网页就撤销证书了。

[root@localhost ~]# systemctl restart nginx.service
[root@localhost ~]# 

最后如图已经撤销：
