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59Please respect copyright.ＰＥＮＡＮＡhmlMnJmiyS
首先查看防火墙的状态：59Please respect copyright.ＰＥＮＡＮＡoDcTra3Jlk
# ufw status59Please respect copyright.ＰＥＮＡＮＡaHdcYAZWvB
如果防火墙开启了，要开放80端口用于certbot验证59Please respect copyright.ＰＥＮＡＮＡ0NBIUlJqky
# ufw allow 8059Please respect copyright.ＰＥＮＡＮＡCgXpLittpC
# ufw allow 443
3 安装certbot: 59Please respect copyright.ＰＥＮＡＮＡ0fzQVJIpaq
# apt install certbot
4. 生成证书：59Please respect copyright.ＰＥＮＡＮＡwrLjjnVYUJ
# certbot certonly59Please respect copyright.ＰＥＮＡＮＡx86AZSP1HW
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。59Please respect copyright.ＰＥＮＡＮＡ9cQf4m40T1
输入email: jinmin.si@outlook.com59Please respect copyright.ＰＥＮＡＮＡVbh0PSudmj
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/59Please respect copyright.ＰＥＮＡＮＡTFgfa9iTAK
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59Please respect copyright.ＰＥＮＡＮＡtrCvyhcB8T
# ps -aux | grep certbot59Please respect copyright.ＰＥＮＡＮＡY23sTp5ir5
# kill 进程号（第二列的数字）
