letsencrypt的免费SSL证书续签及解决办法

Posted 2021-03-04 qinyan20

正常letsencrypt的免费SSL证书续签, 常常需要停止nginx

步骤：

就是先停nginx服务，然后续签操作，在服务器上即：

1. 直接续签证书
find / -name "certbot-auto"
/root/letsencrypt/certbot-auto
/root/certbot-auto

/root/letsencrypt/certbot-auto/certbot-auto renew --force-renew --no-self-upgrade

--force-renew 强制更新
--no-self-upgrade 不更新 letsencrypt

2. 续签证书失败（重新注册证书）

执行： /root/letsencrypt/certbot-auto certonly --standalone --no-self-upgrade -d xxxxx.com

若执行报以下错

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator standalone, Installer None
Obtaining a new certificate
Performing the following challenges:
http-01 challenge for xxxx.com
Cleaning up challenges
Problem binding to port 80: Could not bind to IPv4 or IPv6.

停止nginx
sudo /usr/sbin/nginx -s stop

启动nginx
nginx -c /etc/nginx/nginx.conf
nginx -s reload

最后  用2生成的新的 fullchain.pem 和privkey.pem 替换原来旧的，即可

cp /etc/letsencrypt/live/xxx.com-0001/fullchain.pem /etc/letsencrypt/live/xxx.com/fullchain.pem

cp /etc/letsencrypt/live/xxx.com-0001/privkey.pem /etc/letsencrypt/live/xxx.com/privkey.pem 

sudo /usr/sbin/nginx -t
sudo /usr/sbin/nginx -s reload

访问网站， 可以看到证书已续签 ！！
