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42Please respect copyright.ＰＥＮＡＮＡtgd1ToK1K7
首先查看防火墙的状态：42Please respect copyright.ＰＥＮＡＮＡQ8AxV7twZy
# ufw status42Please respect copyright.ＰＥＮＡＮＡAfcqHyZCrF
如果防火墙开启了，要开放80端口用于certbot验证42Please respect copyright.ＰＥＮＡＮＡsWJHMrBUOh
# ufw allow 8042Please respect copyright.ＰＥＮＡＮＡSuj1oy45l1
# ufw allow 443
3 安装certbot: 42Please respect copyright.ＰＥＮＡＮＡoKSZBnck70
# apt install certbot
4. 生成证书：42Please respect copyright.ＰＥＮＡＮＡCP6mRljXe8
# certbot certonly42Please respect copyright.ＰＥＮＡＮＡi4H42ZawTN
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。42Please respect copyright.ＰＥＮＡＮＡ4eiLohvY6y
输入email: jinmin.si@outlook.com42Please respect copyright.ＰＥＮＡＮＡtMrohXmWix
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/42Please respect copyright.ＰＥＮＡＮＡiJAUujNk1e
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42Please respect copyright.ＰＥＮＡＮＡmcQ91x0OHz
# ps -aux | grep certbot42Please respect copyright.ＰＥＮＡＮＡ6Ip8zDs5ux
# kill 进程号（第二列的数字）
