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57Please respect copyright.ＰＥＮＡＮＡb8VRWJ1FYd
首先查看防火墙的状态：57Please respect copyright.ＰＥＮＡＮＡMjbJv3TYrh
# ufw status57Please respect copyright.ＰＥＮＡＮＡX7NLBqhXOH
如果防火墙开启了，要开放80端口用于certbot验证57Please respect copyright.ＰＥＮＡＮＡE6p8ebnF3d
# ufw allow 8057Please respect copyright.ＰＥＮＡＮＡDnL8lhHIsP
# ufw allow 443
3 安装certbot: 57Please respect copyright.ＰＥＮＡＮＡWRXAFymMKE
# apt install certbot
4. 生成证书：57Please respect copyright.ＰＥＮＡＮＡ3Wc1rchqce
# certbot certonly57Please respect copyright.ＰＥＮＡＮＡAw12OUQnMh
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。57Please respect copyright.ＰＥＮＡＮＡqWVF5aI1Uw
输入email: jinmin.si@outlook.com57Please respect copyright.ＰＥＮＡＮＡBDBNvDYciN
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/57Please respect copyright.ＰＥＮＡＮＡ9wQoQhCaXj
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57Please respect copyright.ＰＥＮＡＮＡLc5zZ95ttT
# ps -aux | grep certbot57Please respect copyright.ＰＥＮＡＮＡFOpNYZMI5g
# kill 进程号（第二列的数字）
