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103Please respect copyright.ＰＥＮＡＮＡiQDxaO8bRa
首先查看防火墙的状态：103Please respect copyright.ＰＥＮＡＮＡhbN3t7N5y1
# ufw status103Please respect copyright.ＰＥＮＡＮＡqn0zX9uC4l
如果防火墙开启了，要开放80端口用于certbot验证103Please respect copyright.ＰＥＮＡＮＡ2GQHCA8fv1
# ufw allow 80103Please respect copyright.ＰＥＮＡＮＡGhhUwhpTTn
# ufw allow 443
3 安装certbot: 103Please respect copyright.ＰＥＮＡＮＡRqsCOPAQVG
# apt install certbot
4. 生成证书：103Please respect copyright.ＰＥＮＡＮＡw13FNlUVMY
# certbot certonly103Please respect copyright.ＰＥＮＡＮＡGOvs6Z7A4d
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。103Please respect copyright.ＰＥＮＡＮＡnSkz5ScEX4
输入email: [email protected]103Please respect copyright.ＰＥＮＡＮＡapIDIyoxQH
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/103Please respect copyright.ＰＥＮＡＮＡAXImVcDXhS
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103Please respect copyright.ＰＥＮＡＮＡq2986A0bsd
# ps -aux | grep certbot103Please respect copyright.ＰＥＮＡＮＡqikWMJzbG4
# kill 进程号（第二列的数字）
