一个Let's Encrypt SSL证书的一键脚本{扣自LNMP}

代码扣自 LNMP 和 vpser的 acme.sh

用法：以dnspod为示例

先把dnspod的token 设置环境变量

# export DP_Id="你的Token ID" && export DP_Key="你的Token Key"

随后执行脚本然后一路根据提示操作即可

# ./cert dp

#!/bin/bash
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
export PATH

# Check if user is root
if [ $(id -u) != "0" ]; then
	echo "Error: You must be root to run this script!"
	exit 1
fi

cert_path=$(pwd)
cert_path="$cert_path/ssl_cert"
