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。
一、在linux下启动oracle
登录到centos,切换到oracle用户权限
1
|
# su – oracle
|
接着输入:
1
|
$ 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:
1
|
sql> shutdown immediate
|
二、检查oracle db监听器是否正常
回到终端机模式,输入:
1
|
$ lsnrctl status
|
检查看看监听器是否有启动
如果没有启动,可以输入:
1
|
$ lsnrctl start
|
启动监听器
1
|
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:
1
|
$ 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,下面创建系统自行启动oracle的脚本。
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。

5
|
# vi /etc/oratab
orcl: /opt/oracle/102 :y
# entries are of the form:
# $oracle_sid:$oracle_home:<n|y>:
|
2. 在 /etc/init.d/ 下创建文件oracle,内容如下:

3. 改变文件权限
1
|
# chmod 755 /etc/init.d/oracle
|
4. 添加服务
1
|
# chkconfig --level 35 oracle on
|
5. 需要在关机或重启机器之前停止数据库,做一下操作
1
2
|
# 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
1
2
3
|
# 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
