linux 环境使用openssl 生CA 和密钥报异常java.lang.NumberFormatException: For input string: "

[浦江之猿]

真的好奇怪，使用shell脚本生成CA和密钥对，报异常keytool error: java.lang.NumberFormatException: For input string: ""，说异常出现在第一条语句，检察了十几遍，尝试了很多次还是不可以，希望大神帮忙解决一下，雪地里跪求等待。单条拿出来执行是没有问题，执行脚本就有问题。脚本如下：
VALIDITY=365

SERVER_KEYSTORE_KEY_PASSWORD=javastudent
CA_PASSWORD=jackrabbit
SERVER_TRUSTSTORE_PASSWORD=htmlking
SERVER_TRUSTSTORE_KEY_PASSWORD=htmlstudent
CLIENT_TRUSTSTORE_PASSWORD=jsonking
CLIENT_TRUSTSTORE_KEY_PASSWORD=jsonstudent

你好，请问你是否在shell脚本开头写[#!/bin/bash]，如果写了请VALIDITY 试用 【 ${VALIDITY} 】 试下。我在CentOS7下测试没有问题如图
