centos7上oracle 开机自启

1. 修改dbstart和dbshut启动关闭脚本,使其启动数据库的同时也自动启动监听器（即启动数据库时启动监听器，停止数据库时停止监听器）：

   vim /oracle/product/11.2.0/db_1/bin/dbstart

   找到下面的代码，在实际脚本代码的前面 

   # First argument is used to bring up Oracle Net Listener
   ORACLE_HOME_LISTNER=$1
   # 将此处的 ORACLE_HOME_LISTNER=$1 修改为 
   ORACLE_HOME_LISTNER=$ORACLE_HOME
   if [ ! $ORACLE_HOME_LISTNER ] ; then
   echo "ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener"
   echo "Usage: $0 ORACLE_HOME"
   else
   LOG=$ORACLE_HOME_LISTNER/listener.log

    同样也修改dbshut脚本：

   vim /oracle/product/11.2.0/db_1/bin/dbshut

    

   # The this to bring down Oracle Net Listener
   ORACLE_HOME_LISTNER=$1
   # 将此处的 ORACLE_HOME_LISTNER=$1 修改为 
   ORACLE_HOME_LISTNER=$ORACLE_HOME
   if [ ! $ORACLE_HOME_LISTNER ] ; then
   echo "ORACLE_HOME_LISTNER is not SET, unable to auto-stop Oracle Net Listener"
   echo "Usage: $0 ORACLE_HOME"
   else
   LOG=$ORACLE_HOME_LISTNER/listener.log

    
2. 新建Oracle服务启动脚本

   vim /etc/init.d/oracle

    

   #!/bin/sh
   # chkconfig: 345 61 61
   # description: Oracle 11g R2 AutoRun Servimces
   # /etc/init.d/oracle
   #
   # Run-level Startup script for the Oracle Instance, Listener, and
   # Web Interface
   export ORACLE_BASE=/oracle
   export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
   export ORACLE_SID=orcl
   export ORACLE_UNQNAME=$ORACLE_SID  
   export PATH=$ORACLE_HOME/bin:/user/sbin:$PATH
   export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
   ORA_OWNR="oracle"
   # if the executables do not exist -- display error
   if [ ! -f $ORACLE_HOME/bin/dbstart -o ! -d $ORACLE_HOME ]
   then
   echo "Oracle startup: cannot start"
   exit 1
   fi
   # depending on parameter -- startup, shutdown, restart
   # of the instance and listener or usage display
   case "$1" in
   start)
   # Oracle listener and instance startup
   su $ORA_OWNR -lc $ORACLE_HOME/bin/dbstart
   echo "Oracle Start Succesful!OK."
   ;;
   stop)
   # Oracle listener and instance shutdown
   su $ORA_OWNR -lc $ORACLE_HOME/bin/dbshut
   echo "Oracle Stop Succesful!OK."
   ;;
   reload|restart)
   $0 stop
   $0 start
   ;;
   *)
   echo $"Usage: `basename $0` {start|stop|reload|reload}"
   exit 1
   esac
   exit 0

    
3. 在/etc新建oratab

   vim /etc/oratab

    插入

   orcl:/oracle/product/11.2.0/db_1:Y

    
4. 检查一下脚本能否正确执行

   cd /etc/rc.d/init.d
   ./oracle start
   ./oracle stop

    注意先给 /etc/oratab 执行权限
5. 加入自动启动行列

   chmod 750 /etc/rc.d/init.d/oracle
   ln -s /etc/rc.d/init.d/oracle /etc/rc2.d/S61oracle
   ln -s /etc/rc.d/init.d/oracle /etc/rc3.d/S61oracle
   ln -s /etc/rc.d/init.d/oracle /etc/rc4.d/S61oracle
   ln -s /etc/rc.d/init.d/oracle /etc/rc0.d/K61oracle
   ln -s /etc/rc.d/init.d/oracle /etc/rc6.d/K61oracle
   chkconfig --level 234 oracle on
   chkconfig --add oracle

    
    
6. 最后重启动一下linux操作系统，检查oracle是否自动启动成功
