CentOS卸载Oracle 11gR2(x64)

环境

OS: CentOS 7.4; hosts: L134; IP: 192.168.1.134  
Oracle安装文件目录:/opt/oracle_install  
ORACLE_BASE:/data/app/oracle  
ORACLE_HOME: /data/app/oracle/product/11.2.0/db_1  
oraInventory: /data/app/oraInventory  
Oracle数据目录:/data/app/oradata/  

方法1:使用oracle自带的deinstall卸载

[oracle@L134 ~]$ cd $ORACLE_HOME/deinstall
[oracle@L134 /data/app/oracle/product/11.2.0/db_1/deinstall]$ ./deinstall 

然后根据提示一步一步进行操作即可。最后一步是确认操作,选择y,回车。

Do you want to continue (y - yes, n - no)? [n]: y

最后还要需要以root身份删除/etc/oraInst.loc这个文件。
我觉得方法2删除更方便更彻底。

方法2:手动删除相关文件和目录

  1. 关闭实例
sqlplus / as sysdba
SQL> shutdown immediate
  1. 关闭listener
lsnrctl stop
  1. 删除安装目录
su -
rm -rf /data/app/oracle/ /data/app/oraInventory/ /data/app/oradata/
  1. 以root权限删除/usr/bin下的相关文件。下周
cd /usr/local/bin/
rm -f dbhome oraenv coraenv 
  1. 删除/etc/oratab
rm -f /etc/oratab
  1. 删除
rm -f /etc/oraInst.loc
  1. 删除oracle用户和用户组(如有必要)
userdel -r oracle
groupdel oinstall
groupdel dba
groupdel oper
  1. 删除启动服务
chkconfig --del oracle
