linux设置oracle数据库和监听开机自动启动

默认的单机oracle数据库中，oracle不会随着操作系统的启动而启动，需要手工启动。下面设置开机自动启动

[oracle@CSICN20RPT01 etc]$ vi oratab 

# This file is used by ORACLE utilities.  It is created by root.sh
# and updated by either Database Configuration Assistant while creating
# a database or ASM Configuration Assistant while creating ASM instance.

# A colon, ':', is used as the field terminator.  A new line terminates
# the entry.  Lines beginning with a pound sign, '#', are comments.
# Entries are of the form:
#   $ORACLE_SID:$ORACLE_HOME::

# The first and second fields are the system identifier and home
# directory of the database respectively.  The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.
#
#
rpt:/u01/app/oracle/product/11.2.0.4/db_1:Y

Note：这里把N改成Y（no该为yes）

[root@CSICN20RPT01 etc]# pwd
/etc

[root@CSICN20RPT01 etc]# vi 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
route add default gw 192.168.40.1

su - oracle -c 'lsnrctl start'
su - oracle -c 'dbstart'

Note：添加红色部分，启动监听，启动数据库

测试：

重启操作系统，查看数据库状态
