Question

I’m trying to add java_home in linux machine (centos 5.8)

I’m adding this part to setting JAVA_HOME and PATH for all users in my machine

vi /etc/profile

export JAVA_HOME=/opt/jdkx.x.x_xx

export PATH=$PATH:$JAVA_HOME/bin

after seting it up, i try to verify it by using echo command

echo $JAVA_HOME

but it does not give me any path.Is there something wrong with my configuration?

Left as a placeholder for comments.

echo $SHELL will tell you which shell you are using. Most likely /bin/bash.

Assuming bash, /etc/profile is only read for a login shell (bash –login), not just a new interactive shell.

i.e. if you

sh1% vi /etc/profile
sh1% bash # /etc/profile not read
sh2% echo $JAVA_HOME
sh2%


sh1% vi /etc/profile
sh2% bash --login # /etc/profile should be read.
sh2% echo $JAVA_HOME
/opt/blah/blah/blah
sh2%
