SSL证书续期(Let's Encrypt免费证书)

Let's Encrypt是免费证书,有效期三个月,续期成功,记录一下过程。

服务器环境: CentOS7.6、Python2.7.5

第一步:在宝塔系统将网站的SSL停用,执行续期命令: /git/letsencrypt/certbot-auto certonly --renew-by-default --email xxx@qq.com -d abc.xxx.com

执行过程: 

Creating virtual environment...
Installing Python packages...
Installation succeeded.
Saving debug log to /var/log/letsencrypt/letsencrypt.log

Your cert will expire on 2020-06-17. To obtain a new or tweaked
version of this certificate in the future, simply run certbot-auto
again. To non-interactively renew *all* of your certificates, run
"certbot-auto renew"

==================================================

 第二步: 检查当前站点的Nginx配置中对证书的引用路径是否正确

第三步:如更改过Nginx配置,则需重启服务

service nginx restart

 

=========  部署成功  ==================================================

过程和原理简单,但在实际实施过程,会遇到无限可能的不确定性导致失败。下面简章列出几个遇到过的问题:

1. 续期命令执行时一直停留在 Installing Python packages...

 解决办法:

vim ~/.pip/pip.conf

[global]
# index-url = https://pypi.doubanio.com/simple/
#index-url=https://pypi.tuna.tsinghua.edu.cn/simple/ #清华镜像,网上99%的文章推荐这个网址,经多次测试未成功
index-url = http://mirrors.aliyun.com/pypi/simple/  #阿里云,一次成功。

[install]
#trusted-host=pypi.doubanio.com
#trusted-host=pypi.huna.tsinghua.edu.cn
trusted-host=mirrors.aliyun.com 阿里云

保存pip.conf 后重新执行续期命令即可。

 

2. 提示.well-known 403错误,目录不可访问。

解决方法:在Nginx配置中增加允许访问设置:

location ~ /.well-known {
allow all;
}
