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161Please respect copyright.ＰＥＮＡＮＡpKeIYPvraz
首先查看防火墙的状态：161Please respect copyright.ＰＥＮＡＮＡQuAFOOyPef
# ufw status161Please respect copyright.ＰＥＮＡＮＡXU1vIoUrem
如果防火墙开启了，要开放80端口用于certbot验证161Please respect copyright.ＰＥＮＡＮＡxEdQPkdEMW
# ufw allow 80161Please respect copyright.ＰＥＮＡＮＡTLlivzPgrA
# ufw allow 443
3 安装certbot: 161Please respect copyright.ＰＥＮＡＮＡvRNVFPYXuh
# apt install certbot
4. 生成证书：161Please respect copyright.ＰＥＮＡＮＡYhoqi2etZe
# certbot certonly161Please respect copyright.ＰＥＮＡＮＡJUZs9CKuRQ
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。161Please respect copyright.ＰＥＮＡＮＡFgrZdLfCLI
输入email: [email protected]161Please respect copyright.ＰＥＮＡＮＡtZG1RNEqDG
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/161Please respect copyright.ＰＥＮＡＮＡXMs2HnLbMT
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161Please respect copyright.ＰＥＮＡＮＡh7TyRVSgvv
# ps -aux | grep certbot161Please respect copyright.ＰＥＮＡＮＡRniEhAwufK
# kill 进程号（第二列的数字）
