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149Please respect copyright.ＰＥＮＡＮＡDNq0wscdwZ
首先查看防火墙的状态：149Please respect copyright.ＰＥＮＡＮＡ0WQbnPAsjM
# ufw status149Please respect copyright.ＰＥＮＡＮＡSS8Jfn1TMF
如果防火墙开启了，要开放80端口用于certbot验证149Please respect copyright.ＰＥＮＡＮＡEeY67wobt6
# ufw allow 80149Please respect copyright.ＰＥＮＡＮＡO3ETKMVllf
# ufw allow 443
3 安装certbot: 149Please respect copyright.ＰＥＮＡＮＡZLgL6NTBWv
# apt install certbot
4. 生成证书：149Please respect copyright.ＰＥＮＡＮＡWAZ8n7xBEU
# certbot certonly149Please respect copyright.ＰＥＮＡＮＡubD2YTNb9b
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。149Please respect copyright.ＰＥＮＡＮＡthJu6ATqbw
输入email: [email protected]149Please respect copyright.ＰＥＮＡＮＡTX1ShbzjJd
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/149Please respect copyright.ＰＥＮＡＮＡyVu9Z9VnUL
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149Please respect copyright.ＰＥＮＡＮＡzwfihr77e1
# ps -aux | grep certbot149Please respect copyright.ＰＥＮＡＮＡWGKl0eohqs
# kill 进程号（第二列的数字）
