You are using a Red Hat derivative of Linux (e.g., CentOS/RHEL/Fedora). When trying to run a mongod command you receive this message: "error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory"
What should you do?
Get different installation media. If you try to install a .tgz file for Ubuntu on CentOS/RHEL/Fedora, you will get this message. The solution is to get new installation media.
