Centos7 error: Failed to initialize NSS library

安装oracle相关连的包时导致yum和rpm都坏了,命令使用不了,出现如下错误提示:

error: Failed to initialize NSS library

There was a problem importing one of the Python modules

required to run yum. The error leading to this problem was:

 

   cannot import name ts

 

Please install a package which provides this module, or

verify that the module is installed correctly.

 

It's possible that the above module doesn't match the

current version of Python, which is:

2.7.5 (default, Aug  2 2016, 04:20:16)

[GCC 4.8.5 20150623 (Red Hat 4.8.5-4)]


个人尝试源码编译重装nss、gcc、python、yum都不管用,就差重装系统了。

最后解决方案:

1、下载nspr(nspr-4.13.1-1.0.el7_3.x86_64.rpm)包,链接:http://mirror.centos.org/centos/7/os/x86_64/Packages/nspr-4.13.1-1.0.el7_3.x86_64.rpm

2、执行命令:rpm2cpio nspr-4.13.1-1.0.el7_3.x86_64.rpm | cpio -idmv

3、执行命令:LD_PRELOAD=./usr/lib64/libnspr4.so yum update nspr

问题解决。

注意: 避免安装相关的glibc.i686包,否则会导致yum、rpm损坏


如果还报错,可以将export LD_PRELOAD=/usr/lib64/libnspr4.so写入/etc/profile,然后再source /etc/profile
