根据网上的经验,说是与64位库路径,修改/etc/pam.d/login 中最后一行,

[root@gpsdb ~]# more /etc/pam.d/login
#%PAM-1.0
auth [user_unknown=ignore success=ok ignore=ignore default=bad] pam_securetty.so
auth       include      system-auth
account    required     pam_nologin.so
account    include      system-auth
password   include      system-auth
# pam_selinux.so close should be the first session rule
session    required     pam_selinux.so close
session    include      system-auth
session    required     pam_loginuid.so
session    optional     pam_console.so

# pam_selinux.so open should only be followed by sessions to be executed in the user context
session required pam_selinux.so open
session optional pam_keyinit.so force revoke
session required /lib/security/pam_limits.so

修改 /lib/security/pam_limits.so 为 /lib64/security/pam_limits.so即可.

修改后,本地用户即可登陆.

一般情况下郑老师的这个问题应该配置操作系统的环境变量的时候没有正确配置。以前部署RAC的时候，遇到过。

后来在网上仔细看了对应的文档要求。

里面有一条

如果是64bit的操作系统，需要配置 etc/pam.d/login

并且指定64bit的库路径。

即加入：

/lib64/security/pam_limits.so

32位的系统：/lib/security/pam_limits.so

64位的系统：/lib64/security/pam_limits.so 或者根本就不需要指定这个参数。

但是我遇到过部署Oracle的哥们，80%的没有在意这个东西。

关键是以前就没有这个问题.
