开机启动普通用户脚本

1.把hadoop、starthadoop.sh stophadoop.sh 拷贝/opt/下面 (注starthadoop.sh stophadoop.sh 是开启、关闭hadoop 脚本，可以根据目录不同更改)

2.把hadoop拷贝/etc/rc.d/init.d/下面

3.chmod 755 /opt/starthadoop.sh stophadoop.sh /etc/rc.d/init.d/hadoop

4.chkconfig --add hadoop　  ← 将hadoop加入到chkconfig中

5.chkconfig hadoop on 　    ← 将hadoop设置为自启动

6.chkconfig --list hadoop　 ← 确认hadoop服务状态 hadoop 0:off 1:off 2:on 3:on 4:on 5:on 6:off　 ← 确认2~5为on的状态就OK

 

7.以后可以用 

 

service hadoop start

 

service hadoop stop

 

service hadoop restart

 

hadoop 文件

#!/bin/bash
#
# hadoop startup script for the Hadoop server
#
# chkconfig: 345 80 20
# description: start the hadooop deamon
#
# Source function library

prog=hadoopC
source /etc/profile

case "$1" in
start)
    echo "Starting Hadoop..."
    su hadoop -c "sh /opt/modules/starthadoop.sh"
;;
stop)
   echo "Stoping Hadoop..."
   su hadoop -c "sh /opt/modules/stophadoop.sh"
;;
restart)
   echo "Restart Hadoop..."
   su hadoop -c "sh /opt/modules/starthadoop.sh"
   su hadoop -c "sh /opt/modules/stophadoop.sh"
;;
*)
    echo "Usage: $prog {start|stop|restart}"
;;
esac
exit 0

 关机运行脚本

touch /var/lock/subsys/hadoop
ln -s /etc/rc.d/init.d/hadoop /etc/rc.d/rc0.d/K99hadoop
