【若泽大数据实战第十八天】Hadoop MySQL 服务自启动配置

配置MySQL服务自启动

[[e-mail] ~]# cd /usr/local/mysql#将服务文件拷贝到init.d下，并重命名为mysql
[[e-mail] mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql 
#赋予可执行权限
[[e-mail] mysql]# chmod +x /etc/rc.d/init.d/mysql
#删除服务
[[e-mail] mysql]# chkconfig --del mysql
#添加服务
[[e-mail] mysql]# chkconfig --add mysql
[[e-mail] mysql]# chkconfig --level 345 mysql on
[[e-mail] 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.


touch /var/lock/subsys/local


su - mysqladmin -c "/etc/init.d/mysql start --federated"


"/etc/rc.local" 9L, 278C written

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
