下面是的这段代码是监控tomcat是否运行，如果运行，则将其停止.文件名称本人叫做shutdown.sh
#!/bin/sh
TomcatID=$(ps -ef |grep hudson-3.01 |grep java | awk ' { print $2 } ')
echo "tomcat的pid为$TomcatID"
Monitor(){
echo "[info]开始监控tomcat...[$(date +'%F %H:%M:%S')]"
if [[ $TomcatID ]]
# 这里判断TOMCAT进程是否存在
then
echo "tomca启动正常"
kill -9 $TomcatID
tempTomcatID=$(ps -ef |grep hudson-3.01 |grep java | awk ' { print $2 } ')
if [[ $tempTomcatID ]]
then
echo "停止失败"
else
echo "成功停止"
fi
else
echo "tomcat没有启动"
fi
}
