缺少共享库：libstdc++.so.6

当在centos6.2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

 * base: centos.ustc.edu.cn
 * centosplus: centos.ustc.edu.cn
 * contrib: centos.ustc.edu.cn
 * extras: centos.ustc.edu.cn
 * updates: centos.ustc.edu.cn
libstdc++-4.4.7-3.el6.i686 : GNU Standard C++ Library
Repo        : base
Matched from:
Other       : libstdc++.so.6

2、然后执行：

yum install libstdc++-4.4.7-3.el6.i686

搞定！
