In Mac OS X, you can set the environment variables in one of the following files :
- ~/.bashrc
- ~/.bash_profile
- ~/.profile
By default, Mac OS X does not has above files, you need to create it manually.
$PATH example
This example shows you how to set “mongodb/bin” folder to the existing $PATH environment variable.
$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
$ mongo -version
-bash: mongo: command not found
$cd ~
$pwd
/Users/mkyong
$touch .bash_profile
$vim .bash_profile
export MONGO_PATH=~/mongodb
export PATH=$PATH:$MONGO_PATH/bin
##restart your terminal
$ mongo -version
MongoDB shell version: 2.0.7
$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/mkyong/mongodb/bin
Done.
Could you also show detail steps of how to configure JAVA_HOME in Mac OS?
That’s almost the same. Just name your environment variable JAVA_HOME and get the path to your java directory:
export JAVA_HOME=/path/to/java
export PATH=$PATH:$JAVA_HOME
Probably should be:
export PATH=$PATH:$JAVA_HOME/bin
Or:
export JAVA_HOME=`/usr/libexec/java_home`
