今天安装RAC对环境配置后，进入ROOT里面，出现各种纠结问题，最后在一学长的指导下，顺利得到解决。

错误：

[root@orclcentos1 ~]# ls

ls: error while loading shared libraries: librt.so.1: cannot open shared object file: No such file or directory

[root@orclcentos1 ~]# vi

vi: error while loading shared libraries: libm.so.6: cannot open shared object file: No such file or directory

[root@orclcentos1 ~]# id

id: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory

[root@orclcentos1 ~]# id

id: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory

[root@orclcentos1 etc]# sar

sar: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory

[root@orclcentos1 etc]# sar

sar: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory

[root@orclcentos1 etc]# sar

sar: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory

...........

正常：

[root@orclcentos1 ~]# pwd

/root

[root@orclcentos1 ~]# pwd

/root

.......

是不是很奇怪，有些可以用，而有些不可以用。其他的centos,oracle都可以正常启用。

最后查看了一台一样的机械，发现 LD_ASSUME_KERNEL参数为空，而此台为4.19.

 

解决：[root@orclcentos1 ~]# unset LD_ASSUME_KERNEL 临时。

vi .bash_profile 去掉或者删除LD_ASSUME_KERNEL  永久

 

一切OK了，linux系统还需要大量的学习的啊。
