一、安装。首先去monit官方下载最新的monit版本，老的版本可能不支持
官网地址是http://mmonit.com/monit/
yum源没有配的话用rpm安装。
yum –y install pam-devel
tar -zxf monit-5.12.tar.gz -C /tmp/
cd /tmp/monit-5.12
./configure --prefix=/usr/local/monit --sysconfdir=/usr/local/monit/etc --without-ssl --without-pam
make && make install
mkdir -p /usr/local/monit/etc
cp monitrc /usr/local/monit/etc/
chmod 600 /usr/local/monit/etc/monitrc
cd /bin
ln –s /usr/local/monit/bin/monit /bin/monit
cp /usr/local/monit/etc/monitrc /etc/monitrc
二、使用。
对monit不熟悉的话，建议首先要熟悉monit的使用。
monit 启动 monit -c /etc/monitrc
停止 monit quit
查看 monit status
重新加载 monit reload
启动监控项 monit start 监控名
其他
# monit -h
Usage: monit [options] {arguments}
Options are as follows:
-cfile Use this control file
-dn Run as a daemon once per nseconds
-gname Set group name for start,stop, restart, monitor and unmonitor
-llogfile Print log information to thisfile
-ppidfile Use this lock file in daemonmode
-sstatefile Set the file monit shouldwrite state information to
-I Do not run in background (needed for run from init)
-t Run syntax check for the control file
-v Verbose mode, work noisy (diagnostic output)
-H[filename] Print SHA1 and MD5 hashes of the file or of stdin if the
filename is omited; monit willexit afterwards
-V Print version number and patchlevel
-h Print this text
Optional action arguments for non-daemonmode are as follows:
start all - Start all services
start name - Only start the named service
stopall - Stop all services
stopname - Only stop the named service
restart all - Stop and start all services
restart name - Only restart the named service
monitorall - Enable monitoring of allservices
monitor name - Only enable monitoring of the named service
unmonitor all - Disable monitoring of all services
unmonitor name - Only disable monitoring ofthe named service
reload - Reinitialize monit
status - Print full status information for each service
summary - Print short status information for each service
quit - Kill monit daemon process
validate - Check all services and start if not running
===================================================================================
三、监控storm
我的storm路径是/usr/storm
1、写一个storm的nimbus启动脚本
#!/bin/bash
/usr/storm/bin/storm nimbus &
并以startstorm.sh命名，保存后给执行权限，并存放在STORM_HOME/bin下边
然后执行权限看看该脚本能执行成功不
2、 查看nimbus进程，呵呵别见怪，nimbus进程名挺长的。。。。
root@master Desktop]# ps -elf | grep nimbus
0 S root 12355 1 5 80 0 - 764995 futex_ 01:47 ? 00:00:04 /usr/java/jdk1.8.0_31/bin/java -server -Dstorm.options= -Dstorm.home=/usr/storm -Dstorm.log.dir=/usr/storm/logs -Djava.library.path=/usr/local/lib:/opt/local/lib:/usr/lib -Dstorm.conf.file= -cp /usr/storm/lib/ring-devel-0.3.11.jar:/usr/storm/lib/carbonite-1.4.0.jar:/usr/storm/lib/tools.macro-0.1.0.jar:/usr/storm/lib/metrics-core-2.2.0.jar:/usr/storm/lib/tools.logging-0.2.3.jar:/usr/storm/lib/compojure-1.1.3.jar:/usr/storm/lib/chill-java-0.3.5.jar:/usr/storm/lib/asm-4.0.jar:/usr/storm/lib/ring-jetty-adapter-0.3.11.jar:/usr/storm/lib/kryo-2.21.jar:/usr/storm/lib/tools.cli-0.2.4.jar:/usr/storm/lib/slf4j-api-1.7.2.jar:/usr/storm/lib/clojure-1.5.1.jar:/usr/storm/lib/servlet-api-2.5.jar:/usr/storm/lib/zkclient-0.3.jar:/usr/storm/lib/joda-time-2.0.jar:/usr/storm/lib/minlog-1.2.jar:/usr/storm/lib/json-simple-1.1.jar:/usr/storm/lib/kafka_2.10-0.8.1.1-scaladoc.jar:/usr/storm/lib/storm-core-0.9.3.jar:/usr/storm/lib/jetty-6.1.26.jar:/usr/storm/lib/commons-io-2.4.jar:/usr/storm/lib/logback-core-1.0.13.jar:/usr/storm/lib/kafka_2.10-0.8.1.1.jar:/usr/storm/lib/objenesis-1.2.jar:/usr/storm/lib/commons-codec-1.6.jar:/usr/storm/lib/zookeeper-3.3.4.jar:/usr/storm/lib/jopt-simple-3.2.jar:/usr/storm/lib/math.numeric-tower-0.0.1.jar:/usr/storm/lib/jetty-util-6.1.26.jar:/usr/storm/lib/snakeyaml-1.11.jar:/usr/storm/lib/jline-2.11.jar:/usr/storm/lib/clj-stacktrace-0.2.2.jar:/usr/storm/lib/commons-fileupload-1.2.1.jar:/usr/storm/lib/log4j-1.2.15.jar:/usr/storm/lib/ring-servlet-0.3.11.jar:/usr/storm/lib/commons-exec-1.1.jar:/usr/storm/lib/kafka_2.10-0.8.1.1-javadoc.jar:/usr/storm/lib/kafka_2.10-0.8.1.1-sources.jar:/usr/storm/lib/clout-1.0.1.jar:/usr/storm/lib/commons-lang-2.5.jar:/usr/storm/lib/log4j-over-slf4j-1.6.6.jar:/usr/storm/lib/slf4j-api-1.7.5.jar:/usr/storm/lib/ring-core-1.1.5.jar:/usr/storm/lib/snappy-java-1.0.5.jar:/usr/storm/lib/reflectasm-1.07-shaded.jar:/usr/storm/lib/hiccup-0.3.6.jar:/usr/storm/lib/disruptor-2.10.1.jar:/usr/storm/lib/core.incubator-0.1.0.jar:/usr/storm/lib/scala-library-2.10.1.jar:/usr/storm/lib/jgrapht-core-0.9.0.jar:/usr/storm/lib/logback-classic-1.0.13.jar:/usr/storm/lib/commons-logging-1.1.3.jar:/usr/storm/lib/clj-time-0.4.1.jar:/usr/storm/conf -Xmx1024m -Dlogfile.name=nimbus.log -Dlogback.configurationFile=/usr/storm/logback/cluster.xml backtype.storm.daemon.nimbus
3、 编辑/etc/monitrc在最后加上下边的内容,这里要讲一下，stormnb是监控名字，matching 后边的内容是上边命令查看到的进程名，版本不同勿照搬，若monit已经启动，则用monit start stormnb启动监控进程。
check process stormnb matching "/usr/java/jdk1.8.0_31/bin/java -server -Dstorm.options= -Dstorm.home=/usr/storm -Dstorm.log.dir=/usr/storm/logs -Djava.library.path=/usr/local/lib:/opt/local/lib:/usr/lib -Dstorm.conf.file= -cp /usr/storm/lib/ring-devel-0.3.11.jar:/usr/storm/lib/carbonite-1.4.0.jar:/usr/storm/lib/tools.macro-0.1.0.jar:/usr/storm/lib/metrics-core-2.2.0.jar:/usr/storm/lib/tools.logging-0.2.3.jar:/usr/storm/lib/compojure-1.1.3.jar:/usr/storm/lib/chill-java-0.3.5.jar:/usr/storm/lib/asm-4.0.jar:/usr/storm/lib/ring-jetty-adapter-0.3.11.jar:/usr/storm/lib/kryo-2.21.jar:/usr/storm/lib/tools.cli-0.2.4.jar:/usr/storm/lib/slf4j-api-1.7.2.jar:/usr/storm/lib/clojure-1.5.1.jar:/usr/storm/lib/servlet-api-2.5.jar:/usr/storm/lib/zkclient-0.3.jar:/usr/storm/lib/joda-time-2.0.jar:/usr/storm/lib/minlog-1.2.jar:/usr/storm/lib/json-simple-1.1.jar:/usr/storm/lib/kafka_2.10-0.8.1.1-scaladoc.jar:/usr/storm/lib/storm-core-0.9.3.jar:/usr/storm/lib/jetty-6.1.26.jar:/usr/storm/lib/commons-io-2.4.jar:/usr/storm/lib/logback-core-1.0.13.jar:/usr/storm/lib/kafka_2.10-0.8.1.1.jar:/usr/storm/lib/objenesis-1.2.jar:/usr/storm/lib/commons-codec-1.6.jar:/usr/storm/lib/zookeeper-3.3.4.jar:/usr/storm/lib/jopt-simple-3.2.jar:/usr/storm/lib/math.numeric-tower-0.0.1.jar:/usr/storm/lib/jetty-util-6.1.26.jar:/usr/storm/lib/snakeyaml-1.11.jar:/usr/storm/lib/jline-2.11.jar:/usr/storm/lib/clj-stacktrace-0.2.2.jar:/usr/storm/lib/commons-fileupload-1.2.1.jar:/usr/storm/lib/log4j-1.2.15.jar:/usr/storm/lib/ring-servlet-0.3.11.jar:/usr/storm/lib/commons-exec-1.1.jar:/usr/storm/lib/kafka_2.10-0.8.1.1-javadoc.jar:/usr/storm/lib/kafka_2.10-0.8.1.1-sources.jar:/usr/storm/lib/clout-1.0.1.jar:/usr/storm/lib/commons-lang-2.5.jar:/usr/storm/lib/log4j-over-slf4j-1.6.6.jar:/usr/storm/lib/slf4j-api-1.7.5.jar:/usr/storm/lib/ring-core-1.1.5.jar:/usr/storm/lib/snappy-java-1.0.5.jar:/usr/storm/lib/reflectasm-1.07-shaded.jar:/usr/storm/lib/hiccup-0.3.6.jar:/usr/storm/lib/disruptor-2.10.1.jar:/usr/storm/lib/core.incubator-0.1.0.jar:/usr/storm/lib/scala-library-2.10.1.jar:/usr/storm/lib/jgrapht-core-0.9.0.jar:/usr/storm/lib/logback-classic-1.0.13.jar:/usr/storm/lib/commons-logging-1.1.3.jar:/usr/storm/lib/clj-time-0.4.1.jar:/usr/storm/conf -Xmx1024m -Dlogfile.name=nimbus.log -Dlogback.configurationFile=/usr/storm/logback/cluster.xml backtype.storm.daemon.nimbus"
start program = "/bin/sh /usr/storm/bin/start_storm.sh" with timeout 30 seconds
stop program = "/usr/bin/kill -9 `ps -elf | grep nimbus | grep -v grep | awk '{print $4}'`"
注意：自己配置storm_home的值和matching “”号中的值要和自己执行ps -elf | grep nimbus得到的进程名一致，最后两句的意思是启动nimbus和停止nimbus。

监控supervisor，core的方法也一样，照着改一下就好。
