Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program

解决办法：

　　方法1：直接在在脚本前添加java环境变量

　　方法2：如果是在 /etc/profile 中导入的环境变量，那么在/root/.bashrc中加入相同环境变量

　　

export JAVA_HOME=/root/jdk/jdk1.8.0_171
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JRE_HOME=$JAVA_HOME/jre
