Linux设置Oracle开机自动启动--oracle12c

1、在terminal中切换到root用户

2、查看/etc/oratab文件的内容，其内容如下[root@golonglee ~]# cat /etc/oratab | grep -v ^$## This file is used by 晦倘佳鳎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.##oel63:/home/oracle/app/oracle/product/11.2.0/dbhome_1:N

3、使用命令vi /etc/oratab编辑文件/etc/oratab，在最后添加如下内容##### what I have written is as follow足毂忍珩ingoel63:/home/oracle/app/oracle/product/11.2.0/dbhome_1:Y#####Finished wrote in 2015-12-24说明：/home/oracle/app/oracle/product/11.2.0/dbhome_1为oracle的安装目录，要根据实际情况进行修改。

4、找到最后的内容oel63:/home/oracle/app/oracle/product/11.2.0/dbhome_1:N

5、复制该行oel63:/home/oracle/app/oracle/product/11.2.0/dbhome_1:N并注释掉

6、粘贴该行，并将该行oel63:/home/oracle/app/oracle/product/11.2.0/dbhome_1:N最后的N改为Y

7、最后按2次ESC键，并输入:wq并按下enter保存，退出

8、使用命令vi /etc/rc.d/rc.local编辑rc.local文件，添加如下内容####拭貉强跳# what I have written is as followin爿讥旌护gsu oracle -lc "/home/oracle/app/oracle/product/11.2.0/dbhome_1/bin/lsnrctl start"su oracle -lc /home/oracle/app/oracle/product/11.2.0/dbhome_1/bin/dbstart#####Finished wrote in 2015-12-24说明：因为第一行命令中有空格所以用双引号（英文的双引号）/home/oracle/app/oracle/product/11.2.0/dbhome_1为oracle的安装目录，要根据实际情况进行修改。

9、最后按2次ESC键，并输入:wq并按下enter保存，退出，重启机器，验证成功。
