解決CentOS缺少共享庫：libstdc++.so.6

當在CentOS 6.2下執行某些命令時，有缺少共享庫的報錯：   error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
解決辦法：  1、執行命令： yum whatprovides libstdc++.so.6   然後會提示哪個安裝包有這個庫文件如下：   [root@localhost ~]# yum whatprovides libstdc++.so.6  Loaded plugins: aliases, changelog, downloadonly, fastestmirror, kabi, presto, refresh-packagekit, security, tmprepo, verify,               : versionlock  Loading support for CentOS kernel ABI  Loading mirror speeds from cached hostfile   * 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、然後執行：   yum install libstdc++-4.4.7-3.el6.i686
