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164Please respect copyright.ＰＥＮＡＮＡaMuVaT0VBm
首先查看防火墙的状态：164Please respect copyright.ＰＥＮＡＮＡr66ViFKd40
# ufw status164Please respect copyright.ＰＥＮＡＮＡw1X6kEGChn
如果防火墙开启了，要开放80端口用于certbot验证164Please respect copyright.ＰＥＮＡＮＡosEO2ad10J
# ufw allow 80164Please respect copyright.ＰＥＮＡＮＡQaa4yonGJo
# ufw allow 443
3 安装certbot: 164Please respect copyright.ＰＥＮＡＮＡFOcLHAMSwN
# apt install certbot
4. 生成证书：164Please respect copyright.ＰＥＮＡＮＡkCOPHVc7Es
# certbot certonly164Please respect copyright.ＰＥＮＡＮＡl4p7BrkggH
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。164Please respect copyright.ＰＥＮＡＮＡ8eTE3wv9YI
输入email: [email protected]164Please respect copyright.ＰＥＮＡＮＡsGbHHrhQio
域名：idealand.xyz
5. 证书生成成功，位于 /etc/letsencrypt/live/idealand.xyz/164Please respect copyright.ＰＥＮＡＮＡfjiXcvFIIg
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164Please respect copyright.ＰＥＮＡＮＡb5JMPJv0TB
# ps -aux | grep certbot164Please respect copyright.ＰＥＮＡＮＡm8lchXImE1
# kill 进程号（第二列的数字）
