linux下oracle设置开机自启动实现方法

在CentOS 6.3下安装完Oracle 10g R2，重开机之后，你会发现Oracle没有自行启动，这是正常的，因为在Linux下安装Oracle的确不会自行启动，必须要自行设定相关参数，首先先介绍一般而言如何启动oracle。

以下分为 手动启动oracle 和 开机自动启动 oracle

手动启动Oracle数据库

一、在Linux下启动Oracle

登录到CentOS，切换到oracle用户权限

# su – oracle

接着输入：

$ sqlplus \"/as sysdba\"

原本的画面会变为

SQL>

接着请输入 SQL> startup 就可以正常的启动数据库了。 另外停止数据库的指令如下： SQL> shutdown immediate 二、检查Oracle DB是否正常 回到终端机模式，输入： $ lsnrctl status

检查看看是否有启动 如果没有启动，可以输入： $ lsnrctl start 启动

SQL> conn sys@orcl as sysdba 然后输入密码，sys以sysdba身份登入数据库。 三、启动emctl

另外也可以发现http://localhost.localdomain:1158/em 目前是没有反应的，这边要另外启动，启动的指令如下：

$ emctl start dbconsole

这个指令运行时间较长，执行完的画面如下：

手动启动Oracle数据库完毕，

系统自行启动Oracle数据库

四、Oracle启动&停止脚本

1. 修改Oracle系统配置文件：/etc/oratab，只有这样，Oracle 自带的dbstart和dbshut才能够发挥作用。

# vi /etc/oratab

orcl:/opt/oracle/102:Y

# Entries are of the form:

# $ORACLE_SID:$ORACLE_HOME::

2. 在 /etc/init.d/ 下创建文件oracle，内容如下：

复制代码代码如下: #!/bin/sh # chkconfig: 35 80 10 # description: Oracle auto start-stop script. # # Set ORA_HOME to be equivalent to the $ORACLE_HOME # from which you wish to execute dbstart and dbshut; # # Set ORA_OWNER to the user id of the owner of the

# Oracle database in ORA_HOME. ORA_HOME=/opt/oracle/102 ORA_OWNER=oracle if [ ! -f $ORA_HOME/bin/dbstart ] then echo \"Oracle startup: cannot start\" exit fi case \"$1\" in 'start') # Start the Oracle databases: echo \"Starting Oracle Databases ... \"

echo \"-------------------------------------------------\" >> /var/log/oracle date +\" %T %a %D : Starting Oracle Databases as part of system up.\" >> /var/log/oracle echo \"-------------------------------------------------\" >> /var/log/oracle su - $ORA_OWNER -c \"$ORA_HOME/bin/dbstart\" >>/var/log/oracle echo \"Done\" # Start the Listener: echo \"Starting Oracle Listeners ... \" echo \"-------------------------------------------------\" >> /var/log/oracle date +\" %T %a %D : Starting Oracle Listeners as part of system up.\" >> /var/log/oracle echo \"-------------------------------------------------\" >> /var/log/oracle su - $ORA_OWNER -c \"$ORA_HOME/bin/lsnrctl start\" >>/var/log/oracle

echo \"Done.\" echo \"-------------------------------------------------\" >> /var/log/oracle date +\" %T %a %D : Finished.\" >> /var/log/oracle echo \"-------------------------------------------------\" >> /var/log/oracle touch /var/lock/subsys/oracle 'stop') # Stop the Oracle Listener: echo \"Stoping Oracle Listeners ... \" echo \"-------------------------------------------------\" >> /var/log/oracle date +\" %T %a %D : Stoping Oracle Listener as part of system down.\" >> /var/log/oracle echo \"-------------------------------------------------\" >> /var/log/oracle su - $ORA_OWNER -c \"$ORA_HOME/bin/lsnrctl stop\" >>/var/log/oracle

echo \"Done.\" rm -f /var/lock/subsys/oracle # Stop the Oracle Database: echo \"Stoping Oracle Databases ... \" echo \"-------------------------------------------------\" >> /var/log/oracle date +\" %T %a %D : Stoping Oracle Databases as part of system down.\" >> /var/log/oracle echo \"-------------------------------------------------\" >> /var/log/oracle su - $ORA_OWNER -c \"$ORA_HOME/bin/dbshut\" >>/var/log/oracle echo \"Done.\" echo \"\" echo \"-------------------------------------------------\" >> /var/log/oracle date +\" %T %a %D : Finished.\" >> /var/log/oracle

echo \"-------------------------------------------------\" >> /var/log/oracle 'restart') $0 stop $0 start esac 我测试的内容为,并且实验成功以下脚本实现了oracle 开机自启

#注意：例子中的oralce命令在/u01/app/oracle/product/10.2.0/db_1/bin/目录。

#修改ORA_HOME的值为ORACLE的目录。

#45,46行一定要加上

1. #!/bin/bash

2. #root

3. #chkconfig: 345 51 49

4. #description: starts the oracle dabase deamons

5. #

6. ORA_HOME=/u01/app/oracle/product/10.2.0/db_1

7. ORA_OWNER=oracle

8. case \"$1\" in

9. 'start')

10. echo -ne \"Starting oracle 11g ... \\n\"

11. su - $ORA_OWNER -c \"$ORA_HOME/bin/dbstart\"

12. echo -e \"Done.\\n\"

13. echo -e \"Starting Oracle Listeners ... \\n\"

14. su - $ORA_OWNER -c \"$ORA_HOME/bin/lsnrctl start\"

15. echo -e \"Done.\\n\"

16. su - $ORA_OWNER -c \"$ORA_HOME/bin/emctl start dbconsole\" #启动web

管理界面:http://host_ip_address:1158/em

17. echo -ne \"input root password......\\n\"

18. su - root -c \"touch /var/lock/subsys/oracle11g\"

19. echo -e \"\\n\"

20. ;;

21. 'stop')

22. echo -ne \"shutting down oracle 11g ... \\n\"

23. su - $ORA_OWNER -c \"$ORA_HOME/bin/dbshut\"

24. echo -ne \"dbshut ok !\\n\"

25. su - $ORA_OWNER -c \"$ORA_HOME/bin/lsnrctl stop\"

26. echo -ne \"lsnrctl stop ok !\\n\"

27. su - $ORA_OWNER -c \"$ORA_HOME/bin/emctl stop dbconsole\"

28. #su - root -c \"/home/oracle/ufsoft/stop.sh\"

29. echo -ne \"input root password......\\n\"

30. su - root -c \"rm -f /var/lock/subsys/oracle11g\"

31. echo

32. ;;

33. 'restart')

34. echo -ne \"restarting oracle 11g ... \\n\"

35. $0 stop

36. $0 start

37. echo

38. ;;

39. *)

40. echo \"Usage: oracle {start|stop|restart} \"

41. exit 1

42. esac

43. exit 0

45.#chkconfig: - 85 15

46.#description:oracle is a World Wide Web server. It is used to server \\dddd

3. 改变文件权限

# chmod 755 /etc/init.d/oracle

4. 添加服务

# chkconfig --level 35 oracle on

#chkconfig --list | grep oracle //查看启动状态

5. 需要在关机或重启机器之前停止数据库，做一下操作

# ln -s /etc/init.d/oracle /etc/rc0.d/K01oracle //关机

# ln -s /etc/init.d/oracle /etc/rc6.d/K01oracle //重启

6. 使用方法

# service oracle start //启动oracle

# service oracle stop //关闭oracle

# service oracle restart //重启oracle

7. 测试

a. 开机自启动
