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89Please respect copyright.ＰＥＮＡＮＡAceZbHvhCh
首先查看防火墙的状态：89Please respect copyright.ＰＥＮＡＮＡ5ZdlEb6bmr
# ufw status89Please respect copyright.ＰＥＮＡＮＡSSyEFtzdIL
如果防火墙开启了，要开放80端口用于certbot验证89Please respect copyright.ＰＥＮＡＮＡLBWe7TC1Ve
# ufw allow 8089Please respect copyright.ＰＥＮＡＮＡcfIeP520qD
# ufw allow 443
3 安装certbot: 89Please respect copyright.ＰＥＮＡＮＡuR0qytrHhx
# apt install certbot
4. 生成证书：89Please respect copyright.ＰＥＮＡＮＡXQu2wTWwau
# certbot certonly89Please respect copyright.ＰＥＮＡＮＡbP4mDCZY1J
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。89Please respect copyright.ＰＥＮＡＮＡgzFiSv0JVq
输入email: [email protected]89Please respect copyright.ＰＥＮＡＮＡdrnv95pBfD
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/89Please respect copyright.ＰＥＮＡＮＡSP0GBGyD0v
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89Please respect copyright.ＰＥＮＡＮＡtob9VTag7d
# ps -aux | grep certbot89Please respect copyright.ＰＥＮＡＮＡ1ahcd4lNvH
# kill 进程号（第二列的数字）
