lsnrctl: error while loading shared libraries: /opt/app/oracle/product/11.2/db_1/lib/libclntsh.so.11

错误描述：

安装好数据库后，在oralce用户下敲入 查看监听状态命令，返回错误提示

[oracle@centos3 ~]$ lsnrctl status
lsnrctl: error while loading shared libraries: /opt/app/oracle/product/11.2/db_1/lib/libclntsh.so.11.1: cannot restore segment prot after reloc: Permission denied

检查为selinux问题

关闭selinux

1、修改swlinux配置文件

vi /etc/selinux/config

[root@centos3 opt]# vi /etc/selinux/config

# 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=enforcing
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted

2、在最后加上SELINUX=disabled；

# 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=enforcing -----------这行注释掉
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted

SELINUX=disabled

3、保存后重启服务器

4、检查是否还有问题
