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83Please respect copyright.ＰＥＮＡＮＡwG8OcDx6G2
首先查看防火墙的状态：83Please respect copyright.ＰＥＮＡＮＡZFpyV7waSy
# ufw status83Please respect copyright.ＰＥＮＡＮＡal0z6ZUqbF
如果防火墙开启了，要开放80端口用于certbot验证83Please respect copyright.ＰＥＮＡＮＡ28yaCydDsO
# ufw allow 8083Please respect copyright.ＰＥＮＡＮＡt0uX1Lb6lO
# ufw allow 443
3 安装certbot: 83Please respect copyright.ＰＥＮＡＮＡYrfqi5VWmE
# apt install certbot
4. 生成证书：83Please respect copyright.ＰＥＮＡＮＡFy5gkGgTHe
# certbot certonly83Please respect copyright.ＰＥＮＡＮＡb2HupRhpnL
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。83Please respect copyright.ＰＥＮＡＮＡd0rlibieWU
输入email: [email protected]83Please respect copyright.ＰＥＮＡＮＡLxx3TCZJcD
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/83Please respect copyright.ＰＥＮＡＮＡlQrQi5o4eE
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83Please respect copyright.ＰＥＮＡＮＡKQ9U7bfLAx
# ps -aux | grep certbot83Please respect copyright.ＰＥＮＡＮＡNC0n4Ain80
# kill 进程号（第二列的数字）
