Reference: Error running yum, missing libsasl2.so.2 file

Error running yum, missing libsasl2.so.2 file

[root@localhost /]# yum repolist

There was a problem importing one of the Python modules

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

libsasl2.so.2: cannot open shared object file: No such file or directory

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:

2.6.6 (r266:84292, Oct 12 2012, 14:23:48)

[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)]

If you cannot solve this problem yourself, please go to

the yum faq at:

http://yum.baseurl.org/wiki/Faq

Missing libsasl2.so.2 file, reinstall or find a computer with this file directly copied to the past.

My solution:

[root@localhost ~]# scp /usr/lib64/libsasl2.so.2 root@192.168.1.253:/usr/lib64/

[root@localhost ~]# yum repolist
