当在CentOS 6.2下执行某些命令时，有缺少共享库的报错：

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

解决办法：

1、执行命令：

yum whatprovides libstdc++.so.6

然后会提示哪个安装包有这个库文件如下：

[root@localhost ~]# yum whatprovides libstdc++.so.6

Loaded plugins: aliases, changelog, downloadonly, fastestmirror, kabi, presto, refresh-packagekit, security, tmprepo, verify,

: versionlock
