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85Please respect copyright.ＰＥＮＡＮＡNnt52D2DcA
首先查看防火墙的状态：85Please respect copyright.ＰＥＮＡＮＡQft2lq0XYP
# ufw status85Please respect copyright.ＰＥＮＡＮＡlCoWl6kF2T
如果防火墙开启了，要开放80端口用于certbot验证85Please respect copyright.ＰＥＮＡＮＡ8LyfY5mT0V
# ufw allow 8085Please respect copyright.ＰＥＮＡＮＡlPRJ3TPtnW
# ufw allow 443
3 安装certbot: 85Please respect copyright.ＰＥＮＡＮＡZCpr60d7iK
# apt install certbot
4. 生成证书：85Please respect copyright.ＰＥＮＡＮＡfrb7pR7eUq
# certbot certonly85Please respect copyright.ＰＥＮＡＮＡrF1I4ODNEI
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。85Please respect copyright.ＰＥＮＡＮＡAp7wIJMEmp
输入email: [email protected]85Please respect copyright.ＰＥＮＡＮＡDdJ19eggLL
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/85Please respect copyright.ＰＥＮＡＮＡuhgzS41z3n
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85Please respect copyright.ＰＥＮＡＮＡr1qOCelhcR
# ps -aux | grep certbot85Please respect copyright.ＰＥＮＡＮＡc5h4WOD17z
# kill 进程号（第二列的数字）
