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58Please respect copyright.ＰＥＮＡＮＡX0KNh5DRSt
首先查看防火墙的状态：58Please respect copyright.ＰＥＮＡＮＡ2Y3spf7Lmv
# ufw status58Please respect copyright.ＰＥＮＡＮＡ8hhLNVMf3d
如果防火墙开启了，要开放80端口用于certbot验证58Please respect copyright.ＰＥＮＡＮＡS9iGeKXEg9
# ufw allow 8058Please respect copyright.ＰＥＮＡＮＡGPMkORK9ly
# ufw allow 443
3 安装certbot: 58Please respect copyright.ＰＥＮＡＮＡmUixIaJRUT
# apt install certbot
4. 生成证书：58Please respect copyright.ＰＥＮＡＮＡnYSZ1KnIK8
# certbot certonly58Please respect copyright.ＰＥＮＡＮＡMnfFvBs0zO
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。58Please respect copyright.ＰＥＮＡＮＡ7XCIt8XlV2
输入email: jinmin.si@outlook.com58Please respect copyright.ＰＥＮＡＮＡAvjjtApwC5
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/58Please respect copyright.ＰＥＮＡＮＡwdxwJe4UiB
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58Please respect copyright.ＰＥＮＡＮＡ40fdzDLy4P
# ps -aux | grep certbot58Please respect copyright.ＰＥＮＡＮＡmSBAVAxl7N
# kill 进程号（第二列的数字）
