daemontools项目：http://cr.yp.to/daemontools.html

1.安装daemontools

mkdir /package
chmod 755 /package
cd /package
wget http://cr.yp.to/daemontools/daemontools-0.76.tar.gz
tar zxf daemontools-0.76.tar.gz
cd admin/daemontools-0.76
vim src/error.h 找到：extern int errno; 改成：#include <errno.h>
package/install

2.监控zookeeper

cd /service
mkdir zookeeper
cd zookeeper
vim run
chmod 755 run


run内容如下：

#!/bin/bash
exec 2>&1
exec  /root/zookeeper/zookeeper-3.4.5/bin/zkServer.sh start

3.运行supervise

nohup supervise /service/zookeeper &

4.实验

kill [zookeeper的pid] 马上一个新的zookeeper进程就出现了，enjoy it
