centos7中oracle开机自启动

一.修改oratab文件 以root身份进入系统,通过vi命令打开文件 vi /etc/oratab 进入vi编辑器后,找到“orcl:/home/oracle/app/oracle/product/11.2.0/db_1:N”, 改为“orcl:/home/oracle/app/oracle/product/11.2.0/db_1:Y”。修改完成后,保存退出vi

# 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. # # #orcl11g:/home/oracle/app/oracle/product/11.2.0/db_1:N orcl11g:/home/oracle/app/oracle/product/11.2.0/db_1:Y

键入命令“vi /etc/rc.d/rc.local” 在vi编辑器中,添加:

su oracle -lc "/home/oracle/app/oracle/product/11.2.0/db_1/bin/lsnrctl start" su oracle -lc "/home/oracle/app/oracle/product/11.2.0/db_1/bin/dbstart"

注:其中/home/oracle/app/oracle/product/11.2.0/db_1 为ORACLE_HOME 二、oracle启动绑定监听器 2.1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

三、新建Oracle服务启动脚本 vim /etc/init.d/oracle 新建一个以oracle命名的文件,并将以下脚本代码复制到文件里

#!/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=/home/oracle/app export ORACLE_HOME=$ORACLE_BASE/oracle/product/11.2.0/db_1 export ORACLE_SID=ORCL export PATH=$PATH:$ORACLE_HOME/bin 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

保存退出 四、检查一下脚本能否正确执行 cd /etc/rc.d/init.d ./oracle start ./oracle stop 五、加入自动启动行列 执行如下命令: 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
