安装完Oracle 11G R 2之后,sqlplus / as sysdba 的时候报如下的错误
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:安装 Oracle 之前配置Linux的时候忘记了SELINUX设置为display了。
方法: 以root身份 vi /etc/sysconfig/selinux 如下图:
# This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - SELinux is fully disabled. SELINUX=disabled # SELINUXTYPE= type of policy in use. Possible values are: # targeted - Only targeted network daemons are protected. # strict - Full SELinux protection. SELINUXTYPE=targeted
把上面的SELINUX=enforcing,改为SELINUX=disabled
然后重启即可。
