启动MongoDB时，提示：
error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
[root@SnsWeb ~]# /usr/local/mongodb/bin/mongod --dbpath=/usr/local/mongodb/data --logpath /usr/local/mongodb/logs/mongodb.log --fork /usr/local/mongodb/bin/mongod: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory [root@SnsWeb ~]#
报错提示：缺少共享库！
解决方案：
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@SnsWeb ~]# yum whatprovides libstdc++.so.6 Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile libstdc++-4.4.7-11.el6.i686 : GNU Standard C++ Library Repo : base Matched from: Other : libstdc++.so.6
2、然后执行
yum -y install libstdc++-4.4.7-11.el6.i686
搞定！
