最近配置脚本定时用ks3服务存储日志文件，ks3执行需要配置java变量，直接shell执行都没有问题，但是配置crontab，则不能正常执行。定时任务报错日志如下：

Subject: Cron <root@vm192-168-5-15> sh /vnum/monitorshell/synLogToKs3.sh

原来是在定时任务中执行，脚本无法引用到java环境。查看查看环境变量:echo $PATH

[root@vm192-168-5-15 monitorshell]# echo $PATH
    /usr/lib64/qt-3.3/bin:/var/local/jdk1.8.0_172/bin:/var/local/jdk1.8.0_172/jre/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/root/bin
    [root@vm192-168-5-15 monitorshell]#

在脚本/vnum/monitorshell/synLogToKs3.sh  起始配置引用环境变量：

export PATH=$PATH:/var/local/jdk1.8.0_172/bin:/var/local/jdk1.8.0_172/jre/bin

测试定时执行，问题解决。
