storm主从节点配置监控脚本
一、目的
配置重启脚本，防止服务停止影响业务。
二、配置思路
通过监测服务进程查看服务是否运行，当服务进程不存在进行自重启
配置Jstorm主节点
配置jstorm从节点 supervisor进行重启
三、配置方法
1.配置jstorm主节点
主节点涉及到两个进程：NimbusServe、supervisor
（当服务停止后，主节点应先启动NimbusServe进程，在启动supervisor）

#日志输出
Nimerror=/tmp/sup-Nimerror.log
superror=/tmp/sup-error.log
source /etc/profile #因cronab不支持则添加环境变量
str=$"\n" #回车符号
#监控主节点，主节点需先启动NimbusServer进程，再启动upervisor进程
NimbusServer=/usr/local/jdk1.7.0_45/bin/jps | grep NimbusServer | grep -v grep | awk '{print $2}'
#监控从节点，从节点仅包含Supervisor进程
supervisor=/usr/local/jdk1.7.0_45/bin/jps | grep Supervisor | grep -v grep | awk '{print $2}'
if [ -z "$NimbusServer" ] then
{
echo "date: NimbusServer is down" >>$Nimerror
/usr/local/jstorm-0.9.6.2/bin/jstorm nimbus&
sleep 10
echo -e "$str"
}
elif [ -z "$supervisor" ] then {
echo "date: supervisor is down" >>$superror
/usr/local/jstorm-0.9.6.2/bin/jstorm supervisor&
sleep 10
echo -e "$str"
}
fi

2.配置jstorm从节点
配置从节点监控脚本：
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#!/bin/sh
#日志输出
source /etc/profile
suplog=/tmp/sup-start.log
superror=/tmp/sup-error.log
str=$"\n"
supervisor=/usr/local/jdk1.7.0_45/bin/jps | grep Supervisor | grep -v grep | awk '{print $2}'
if [ -z "$supervisor" ]
then
{
echo "date: listen port is down" >>$superror
/usr/local/jstorm-0.9.6.2/bin/jstorm supervisor&
sleep 10
echo -e "$str"
}
else
{
echo "date :正常 " >>$suplog
}
fi
