Multiple Mongo Versions

When I run mongo shell from ~ / Downloads / mongodb-osx-x86_64-2.4.5 / bin it runs version 2.4.5

 ./mongo
MongoDB shell version: 2.4.5

This is the version I just downloaded. However, when I run the mongo command from anywhere in my terminal, it launches a different version. I think this is because I (obviously) installed Mongo earlier.

MongoDB shell version: 2.2.0
connecting to: test

What do I need to do to make 2.4.5 respond to "mongo" from anywhere in the terminal (i.e. replace 2.2.0 with 2.4.5)

I just needed to update my path in the bash_profile file to the location of the newer version



export PATH="/path/to/monogdb/bin:$PATH"

There is no reason why multiple concurrent releases of mongo cannot be installed. You can have multiple versions of mongo, and each one starts a different storage engine and also participates in a replica set.

Here are 3 installations on my mac for example.

drwxr-xr-x@ 18 rohitsood  staff    612 Aug 21 18:53 mongodb-osx-x86_64-2.6.3
drwxr-xr-x@  6 rohitsood  staff    204 Jan  4 20:25 mongodb-osx-x86_64-3.0.8
drwxr-xr-x@  8 rohitsood  staff    272 Jan  7 12:31 mongodb-osx-x86_64-3.2.0

if you want to start an instance of mongod that maps to version 3.2 (latest) then make sure your path points to it.



Navigate to your Home (~) folder and open the .profile file to make these changes.

Here my view looks like a link

#Set up MongoDB
#export MONGODB_HOME=/Users/rohitsood/servers/mongodb-osx-x86_64-2.6.3
#export MONGODB_HOME=/Users/rohitsood/servers/mongodb-osx-x86_64-3.0.8
export MONGODB_HOME=/Users/rohitsood/servers/mongodb-osx-x86_64-3.2.0
export PATH=${MONGODB_HOME}/bin:${PATH}

Open up a new terminal and mongo should work as expected.
