CentOS Oracle11gR2 设置开机自动启动CentOS Oracle11gR2 设置开机自启动

[1] 更改/etc/oratab

[root@localhost ~]# vi /etc/oratab
#
# This file is used by ORACLE utilities.
It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.
# 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:<N|Y>:
#
# 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.
#
#
MFGS:/usr/oracle/app/product/11.2.0/dbhome_1:Y #改变此处

[2] oracle用户profile文件中增加SID环境变量

[root@localhost ~]# vi /home/oracle/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
# add at the last line
umask 022
export ORACLE_BASE=/usr/oracle/app
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
export PATH=$PATH:$ORACLE_HOME/bin
#在文件末尾增加

export ORACLE_SID=orcl

[3] 创建启动Oracle的Init脚本

[root@localhost ~]# vi /etc/init.d/oracle
#!/bin/bash
# oracle: Start/Stop Oracle Database 11g R2
#
# chkconfig: 345 90 10
#此行以及下一行注释为必需，否则不能被chkconfig添加为自动启动
# description: The Oracle Database is an Object-Relational Database Management System.
#
# processname: oracle
. /etc/rc.d/init.d/functions
LOCKFILE=/var/lock/subsys/oracle
ORACLE_HOME=/u01/oracle/app/product/11.2.0/db_1
ORACLE_USER=oracle
case "$1" in
'start')
if [ -f $LOCKFILE ]; then
echo $0 already running.
exit 1
fi
echo -n $"Starting Oracle Database:"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/lsnrctl start"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/dbstart $ORACLE_HOME"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/emctl start dbconsole"
touch $LOCKFILE
;;
'stop')
if [ ! -f $LOCKFILE ]; then
echo $0 already stopping.
exit 1
fi
echo -n $"Stopping Oracle Database:"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/lsnrctl stop"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/dbshut"
su - $ORACLE_USER -c "$ORACLE_HOME/bin/emctl stop dbconsole"
rm -f $LOCKFILE
;;
'restart')
$0 stop
$0 start
;;
'status')
if [ -f $LOCKFILE ]; then
echo $0 started.
else
echo $0 stopped.
fi

;;
*)
echo "Usage: $0 [start|stop|status]"

exit 1
esac
exit 0

[4] 更改启动脚本权限

[root@localhost ~]# chmod 755 /etc/rc.d/init.d/oracle

[5] 启动oracle数据库

[root@localhost ~]# service oracle start
