Solve the error of starting MongoDB: error while loading shared libraries: libstdc++.so.6:cannot open shared object file:

When starting MongoDB, the prompt is:

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 ~]#

Error reason: missing libstdc++.so.6 runtime library

Solution: Install the libstdc++.so.6 runtime library

1. Execute commands

yum whatprovides libstdc++.so.6

Then it will prompt which installation package has this library file, as follows:

[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. Then execute

yum -y install libstdc++-4.4.7-11.el6.i686

It is very simple. When there are various problems with the system or software at work, don’t rush to ask Baidu. Try to read the error message and solve the related problems yourself according to the error message. If it is in English, it can also improve your English reading level.
