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82Please respect copyright.ＰＥＮＡＮＡKF5udXqVUD
首先查看防火墙的状态：82Please respect copyright.ＰＥＮＡＮＡXzw10WZhJA
# ufw status82Please respect copyright.ＰＥＮＡＮＡxs5mNp3U7k
如果防火墙开启了，要开放80端口用于certbot验证82Please respect copyright.ＰＥＮＡＮＡKdm2vHzB8C
# ufw allow 8082Please respect copyright.ＰＥＮＡＮＡfsw45IgFME
# ufw allow 443
3 安装certbot: 82Please respect copyright.ＰＥＮＡＮＡawG3g75yJj
# apt install certbot
4. 生成证书：82Please respect copyright.ＰＥＮＡＮＡucTZ8HjZNB
# certbot certonly82Please respect copyright.ＰＥＮＡＮＡF7njCNLQqw
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。82Please respect copyright.ＰＥＮＡＮＡcTSu4RqXZV
输入email: [email protected]82Please respect copyright.ＰＥＮＡＮＡRgIJM0EeHY
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/82Please respect copyright.ＰＥＮＡＮＡsKgx3w9Hop
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82Please respect copyright.ＰＥＮＡＮＡBzF1ojehKs
# ps -aux | grep certbot82Please respect copyright.ＰＥＮＡＮＡZKfSU6wVgR
# kill 进程号（第二列的数字）
