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94Please respect copyright.ＰＥＮＡＮＡtxfyEZS4Gm
首先查看防火墙的状态：94Please respect copyright.ＰＥＮＡＮＡxIzTUAzUft
# ufw status94Please respect copyright.ＰＥＮＡＮＡ5hm1WmiLNY
如果防火墙开启了，要开放80端口用于certbot验证94Please respect copyright.ＰＥＮＡＮＡ6kVowl1JN4
# ufw allow 8094Please respect copyright.ＰＥＮＡＮＡ3VMKNwSvbi
# ufw allow 443
3 安装certbot: 94Please respect copyright.ＰＥＮＡＮＡD1qDjZEAbO
# apt install certbot
4. 生成证书：94Please respect copyright.ＰＥＮＡＮＡtaxaMCIYJf
# certbot certonly94Please respect copyright.ＰＥＮＡＮＡGZbbphhB6m
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。94Please respect copyright.ＰＥＮＡＮＡIu83XxWbi4
输入email: [email protected]94Please respect copyright.ＰＥＮＡＮＡ5VI0GkAjVv
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/94Please respect copyright.ＰＥＮＡＮＡ0vj4CZqYqs
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94Please respect copyright.ＰＥＮＡＮＡZNFp30TZiK
# ps -aux | grep certbot94Please respect copyright.ＰＥＮＡＮＡYXjTfdIvHE
# kill 进程号（第二列的数字）
