mysql和Hadoop的开机自启动

配置MySQL服务自启动

[root@hadoop000 ~]# cd /usr/local/mysql

#将服务文件拷贝到init.d下，并重命名为
mysql
[root@hadoop000 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql 

#赋予可执行权限

[root@hadoop000 mysql]# chmod +x /etc/rc.d/init.d/mysql

#删除服务

[root@hadoop000 mysql]# chkconfig --del mysql

#添加服务

[root@hadoop000 mysql]# chkconfig --add mysql

[root@hadoop000 mysql]# chkconfig --level 345 mysql on

[root@sht-sgmhadoopnn-01 mysql]# vi /etc/rc.local
#!/bin/sh

#
# This script will be executed *after* all the other init scripts.

# You can put your own initialization stuff in here if you don't

# want to do the full Sys V style init stuff.

配置 Hadoop 服务自启动

1、进入到/etc/init.d目录下，编辑一个新的脚本文件
hadoop
# cd /etc/init.d
# vi hadoop

2、编辑脚本文件
hadoop

#！/bin/bash

#chkconfig:345

#description:script to start/stop hadoop

su - hadoop <<!

case $1 in

start)

sh /home/hadoop/app/hadoop-2.6.0-cdh5.7.0/sbin/start-all.sh

;;

stop)

sh /home/hadoop/app/hadoop-2.6.0-cdh5.7.0/sbin/stop-all.sh

;;

*)

echo "Usage:$0(start|stop)"

;;

esac

exit

!

3、保存退出，用chmod修改该文件权限

# chmod -R 775 hadoop

4、设置hadoop为开机自启动

# chkconfig --add hadoop

# chkconfig --level 345 hadoop on
