Hi,
If you want to install MongoDB without root/sudo access required in any steps, you can use the generic Linux binaries instead of the packaged install:
You'll have to create your own service definition and config file (or pass parameters on the command line when starting `mongod`). Assuming you have correct permissions on the provided dbpath, you can run the MongoDB binaries from any directory (as any user).
For an example config see:
Note that packaged installs run MongoDB as the `mongod` user or another non-root account. The packages only require root/sudo access for installing and managing the service (start/stop/restart).
