[root@localhost ~]# vim /etc/rc.local
touch /var/lock/subsys/local

2,redhat操作系统下面，用dbstart的方式
2.1，测试
[oracle@localhost ~]$ /oracle/app/oracle/product/11.2.0/dbhome_1/bin/dbstart
ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener
Usage: /oracle/app/oracle/product/11.2.0/dbhome_1/bin/dbstart ORACLE_HOME
[oracle@localhost ~]$
有报错信息，提示ORACLE_HOME不识别，如下解决方案，修改dbstart和dbstut，有的版本dbstut找不到不存在，可以忽略。
vim /oracle/app/oracle/product/11.2.0/dbhome_1/bin/dbstart
vim /oracle/app/oracle/product/11.2.0/dbhome_1/bin/dbstut

将
ORACLE_HOME_LISTNER =$1

改成
ORACLE_HOME_LISTNER=$ORACLE_HOME

2.2，[root@localhost ~]# vim /etc/oratab
powerdes:/oracle/app/oracle/product/11.2.0/dbhome_1:Y

2.3 在rc.local里面设置开机自启动
[root@localhost bin]# vim /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 - oracle -lc "/oracle/app/oracle/product/11.2.0/dbhome_1/bin/lsnrctl start"
su - oracle -c "/oracle/app/oracle/product/11.2.0/dbhome_1/bin/dbstart"db"

服务器重启生效。
