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56Please respect copyright.ＰＥＮＡＮＡe44Jsl3w6K
首先查看防火墙的状态：56Please respect copyright.ＰＥＮＡＮＡhYEtpW89H8
# ufw status56Please respect copyright.ＰＥＮＡＮＡl7UN4ctmQ3
如果防火墙开启了，要开放80端口用于certbot验证56Please respect copyright.ＰＥＮＡＮＡcGp9k6fDAm
# ufw allow 8056Please respect copyright.ＰＥＮＡＮＡ2Ml8lg6Snf
# ufw allow 443
3 安装certbot: 56Please respect copyright.ＰＥＮＡＮＡDVCXCHyGPN
# apt install certbot
4. 生成证书：56Please respect copyright.ＰＥＮＡＮＡwaksQkfgbO
# certbot certonly56Please respect copyright.ＰＥＮＡＮＡfAAcluZtCa
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。56Please respect copyright.ＰＥＮＡＮＡfr2w6yAfk1
输入email: jinmin.si@outlook.com56Please respect copyright.ＰＥＮＡＮＡINnvalWvIc
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/56Please respect copyright.ＰＥＮＡＮＡlE2uLcAjgD
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56Please respect copyright.ＰＥＮＡＮＡW37TF7l8p5
# ps -aux | grep certbot56Please respect copyright.ＰＥＮＡＮＡv63gsNOqgo
# kill 进程号（第二列的数字）
