CentOS Oracle11gR2 设置开机自启动

时间:2015-01-16 02:13来源:linux.it.net.cn 作者:IT

[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 /usr/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=MFGS

[3] 创建启动Oracle的Init脚本

 
[root@localhost ~]# vi /etc/rc.d/init.d/oracle
# this is an example
#!/bin/bash

# oracle: Start/Stop Oracle Database 11g R2
#
# chkconfig: 345 90 10
# 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=/usr/oracle/app/product/11.2.0/dbhome_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

相应关闭oracle数据库的命令为

[root@localhost ~]# service oracle stop

[6] 设置oracle为开机自启动

[root@localhost ~]# chkconfig oracle on
[root@localhost ~]# chkconfig --list oracle
