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78Please respect copyright.ＰＥＮＡＮＡ8L9RreCGNB
首先查看防火墙的状态：78Please respect copyright.ＰＥＮＡＮＡiGmlyURNNs
# ufw status78Please respect copyright.ＰＥＮＡＮＡ9e7gYARDwp
如果防火墙开启了，要开放80端口用于certbot验证78Please respect copyright.ＰＥＮＡＮＡdglFJIQ2NT
# ufw allow 8078Please respect copyright.ＰＥＮＡＮＡf8xZjQjm0x
# ufw allow 443
3 安装certbot: 78Please respect copyright.ＰＥＮＡＮＡVivVNir4hx
# apt install certbot
4. 生成证书：78Please respect copyright.ＰＥＮＡＮＡRfgF3EHklD
# certbot certonly78Please respect copyright.ＰＥＮＡＮＡc5njPTvDVZ
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。78Please respect copyright.ＰＥＮＡＮＡWPKUsIuJg9
输入email: [email protected]78Please respect copyright.ＰＥＮＡＮＡqRdda5hrgV
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/78Please respect copyright.ＰＥＮＡＮＡWsU0Ql7OqJ
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78Please respect copyright.ＰＥＮＡＮＡBilmOjxpW8
# ps -aux | grep certbot78Please respect copyright.ＰＥＮＡＮＡe8WeSrOySG
# kill 进程号（第二列的数字）
