(I know there are a lot of questions about this on stackoverflow and this site but no one fits my problem.).

I am a new recruit of mongodb. I am trying to install the v3.0.3 on my ubuntu 32 bit following their docs but cant get through it after issuing the install command. Googling a while, I learned that they do not prefer to use 32 bit but has a counterpart, to use the .tgz file I downloaded on their website for 32 bit.

I extracted the mongodb-linux-i686-3.0.3.tgz and place it to a folder on my desktop following their docs and the README inside the extracted folder.

When I issue the command ./mongod inside bin directory to start mongod i got this message

2015-05-14T10:50:47.416+0800 I CONTROL  
2015-05-14T10:50:47.416+0800 W CONTROL  32-bit servers don't have    journaling enabled by default. Please use --journal if you want durability.

This is my permission inside the extracted folder

How to fix this guys? I am a mysql user and I do not know a thing about this. I really want to try this out because I want to try MEAN.

Thanks in advance.

Seems theres no one online so my immediate fix on this is to install the v2.4 of mongodb..

I followed the answer in this question How can I uninstall MongoDB and reinstall the latest version?

I just want to try mongodb to try MEAN. If you have knowledge about my question, please post it.



Looks like the following is a viable workaround:

  1. Create a folder /data/db/ and provide proper write and read access

  2. Start mongo db using mongodb --journal
