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60Please respect copyright.ＰＥＮＡＮＡdQuMXImeA0
首先查看防火墙的状态：60Please respect copyright.ＰＥＮＡＮＡSKvamtdrhU
# ufw status60Please respect copyright.ＰＥＮＡＮＡsK7DED6R7W
如果防火墙开启了，要开放80端口用于certbot验证60Please respect copyright.ＰＥＮＡＮＡrqTPMAn3BU
# ufw allow 8060Please respect copyright.ＰＥＮＡＮＡnSKqWXGnwp
# ufw allow 443
3 安装certbot: 60Please respect copyright.ＰＥＮＡＮＡbfBsQvlli5
# apt install certbot
4. 生成证书：60Please respect copyright.ＰＥＮＡＮＡ1nvIVTwFea
# certbot certonly60Please respect copyright.ＰＥＮＡＮＡVcIEvkzq9i
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。60Please respect copyright.ＰＥＮＡＮＡh0AtdpQ1nG
输入email: jinmin.si@outlook.com60Please respect copyright.ＰＥＮＡＮＡJKYOk9d7tQ
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/60Please respect copyright.ＰＥＮＡＮＡziDyY5B712
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60Please respect copyright.ＰＥＮＡＮＡ6Ry6NxP6IF
# ps -aux | grep certbot60Please respect copyright.ＰＥＮＡＮＡp847rHC3lW
# kill 进程号（第二列的数字）
