linux设置开机启动方法：

1.切换到root用户
2.vi /etc/rc.d/rc.local

?? 增加要执行的命令，

?? 比如redis,将启动命令加入到文件中并保存，这样在下次开启启动时就生效了

#!/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

redis-server /usr/local/redis/etc/redis.conf

3.如果希望立刻执行，则执行/etc/rc.d/rc.local即可。

[root@localhost ~]# /etc/rc.d/rc.local
