设置的crontab脚本无法启动、关闭tomcat解决

#!/bin/bash#pid=$(ps -ef | grep tomcat | grep -v grep | awk '{print $2}')#pid=$(ps -ef | grep tomcat | grep -v grep | awk '{print $2}')#echo "tomcat的pid为$TomcatID"#d_today=$ date "+%Y-%m-%d %H%M%S"d_today=`date '+%Y-%m-%d %H:%M:%S'`pid=$(curl -I -m 10 -o /dev/null -s -w %{http_code} http://www.qq.com)if [$pid -eq 200]; thenecho "tomcat pid is $pid at${d_today}"    echo "tomcat pid is $pid at${d_today}/n">>/data/webbak/task_shell/shelllog/tomcat.txt#if [$pid]; then   #cd /data/mysoft/apache-tomcat-8.5.11/bin && ./startup.sh  # rm -rf /data/mysoft/apache-tomcat-8.5.11/work  #echo 'Unitop@19866'|sudo -S /data/mysoft/apache-tomcat-8.5.11/bin/startup.sh   #echo "tomcat is stop at${d_today}/n">>/data/webbak/task_shell/shelllog/tomcat.txt   echo "tomcat is stop at${d_today}"else/data/mysoft/apache-tomcat-8.5.11/bin/startup.shecho "tomcat is stop at${d_today}/n">>/data/webbak/task_shell/shelllog/tomcat.txt  #kill -9 $pid  #echo kill is okfi

发现了一个问题就是单独执行这个脚本能关闭、启动tomcat放到crontab里面定时执行就不行了。

解决办法：

在catalina.sh里面加入jdk和jre的路径，配环境：

    

[plain] view plain copy

1. export JAVA_HOME=/usr/java/jdk1.7.0_67   
2. export JRE_HOME=$JAVA_HOME/jre  

这样放到crontab是执行成功了的
