1. 将需要生成SSL证书的域名解析到它對應的IP地址
2. 检查防火墙的设置124Please respect copyright.ＰＥＮＡＮＡCMU6KjAmrm
首先查看防火墙的状态：124Please respect copyright.ＰＥＮＡＮＡRrPPpJz6hz
# ufw status124Please respect copyright.ＰＥＮＡＮＡ6IqkgegYQD
如果防火墙开启了，要开放80端口用于certbot验证124Please respect copyright.ＰＥＮＡＮＡs7AI2as7Ul
# ufw allow 80124Please respect copyright.ＰＥＮＡＮＡ1iYKXG36os
# ufw allow 443
3 安装certbot: 124Please respect copyright.ＰＥＮＡＮＡuXMncaArOW
# apt install certbot
4. 生成证书：124Please respect copyright.ＰＥＮＡＮＡV8tlSn0zpL
# certbot certonly124Please respect copyright.ＰＥＮＡＮＡRQx5VLg8X7
选择authenticate时，如果服务上有apache或其它网站服务器在80端口运行，选择2使用已有的网站服务器验证；否则选1让certbot创建一个临时的网站来验证。124Please respect copyright.ＰＥＮＡＮＡGzSiDo0DTS
输入email: [email protected]124Please respect copyright.ＰＥＮＡＮＡ3HUNJssM5S
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/124Please respect copyright.ＰＥＮＡＮＡfhO3RNdrDL
fullchain.pem为公钥，privkey.pem为私钥
6. 如果运行certbot的过程中断线，再次运行前需要结束之前的进程124Please respect copyright.ＰＥＮＡＮＡyzKFuKwi2m
# ps -aux | grep certbot124Please respect copyright.ＰＥＮＡＮＡe9hD5U64u9
# kill 进程号（第二列的数字）
