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172Please respect copyright.ＰＥＮＡＮＡUqSrZxyCXW
首先查看防火墙的状态：172Please respect copyright.ＰＥＮＡＮＡ9aeFPtAyMn
# ufw status172Please respect copyright.ＰＥＮＡＮＡUxKmuXpjOa
如果防火墙开启了，要开放80端口用于certbot验证172Please respect copyright.ＰＥＮＡＮＡ6mSj54COOj
# ufw allow 80172Please respect copyright.ＰＥＮＡＮＡ5oVYcJcLnb
# ufw allow 443
3 安装certbot: 172Please respect copyright.ＰＥＮＡＮＡvhzQU6Aadd
# apt install certbot
4. 生成证书：172Please respect copyright.ＰＥＮＡＮＡQj4dYg22j5
# certbot certonly172Please respect copyright.ＰＥＮＡＮＡFPnoUhSd22
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。172Please respect copyright.ＰＥＮＡＮＡmT1NYtZiPd
输入email: [email protected]172Please respect copyright.ＰＥＮＡＮＡKfFsA8C7I5
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/172Please respect copyright.ＰＥＮＡＮＡVDKKYGoPTW
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172Please respect copyright.ＰＥＮＡＮＡj4mqqSC6N1
# ps -aux | grep certbot172Please respect copyright.ＰＥＮＡＮＡcYPD7MjP73
# kill 进程号（第二列的数字）
