mongodump and mongorestore on PythonAnywhere

Question

I am using PythonAnywhere to host my web application. Using Mongodb as my database. Now my task is to take backup periodically and restore specific version of mongodb whenever I want.

To do it on local(windows machine), it is pretty easy. Install Mongodb utilities and execute command

mongodump --mongodbConnectionString   //From location where this executable is stored
mongorestore --mongodbConnectionString

Now my challenge is to do it from PythonAnywhere. Here how should I use these utilities?

---

I have Linux executables for mongodb from mongodb site, I extracted bin folder from it, it look like below

Now I moved this bin folder to PythonAnywhere and tried to execute mongodump command

~/../applications/mongodb-linux-x86_64-ubuntu1404-3.4.0/bin$ ./mongodump mongodbConnectionString

it failed with below error

bash: ./mongodump: Permission denied

My question is how to do mongodump and mongorestore from PythonAnywhere? My final goal is to do periodic backup of mongodb database

Answer 1

You need to setup correctly MongoDB binaries inside PythonAnywhere.

Normally, execution fails due wrong permissions.

Make sure:
- You have execution permissions (chmod u+x file)
- Binnaries have proper owner    (chown user file)
- Binnaries have proper group    (chgrp group file)

Note: You need to be sudoer to grant such permissions
