装好Oracle后打开sqlplus权限不足：cannot restore segment prot after reloc: Permission denied

 

问题：

[root@Kernelry ~]# su - oracle

[oracle@Kernelry ~]$ sqlplus sys/oralinux as sysdba

sqlplus: error while loading shared libraries: /u01/app/oracle/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1: cannot restore segment prot after reloc:Permission denied

 

原因：

查看 /var/log/messages 日志文件看到这么一条信息

Sep 10 03:19:27 Kernelry setroubleshoot:SELinux is preventing sqlplus from loading /u01/app/oracle/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1 which requires text relocation. For complete SELinux messages. run sealert -l bd06f0a6-a7fa-4045-8e70-27acdc122b4f

                    原来是SELinux机制阻止了sqlplus的加载

 

解决方法：

1、临时设置： root用户执行 setenforce 1 ——更改SELinux为permissive状态

2、永久设置：编辑/etc/selinux/config ，修改SELINUX=permissive
