Why my /etc/profile can't work??

binary · 10-26-2006, 12:51 AM

I setup tomcat and I set the JAVA environment variable in /etc/profile. After I restart my computer and start tomcat, it report NO JAVA environment variable was set. I echo $JAVA_HOME and there is nothing to display.

Please help me: why my setting in /etc/profile doesn't work??

i'd guess you've not exported the variable. run "export JAVAHOME=..." not just "JAVAHOME=..." as the later is only held within the scope of the profile script. so when the profile script is finished, the variable is destroyed. export pushes that variable back out to the users login shell.

Thanks at first.

This is my /etc/profile:

Quote:

# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).

if [ "`id -u`" -eq 0 ]; then
PATH=".:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/ X11"
else
PATH=".:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games"
fi

if [ "$PS1" ]; then
if [ "$BASH" ]; then
PS1='\u@\h:\w\$ '
else
if [ "`id -u`" -eq 0 ]; then
PS1='# '
else
PS1='$ '
fi
fi
fi

export JAVA_HOME=/usr/lib/j2sdk1.5-sun
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

umask 022

But it doesn't work. When I type "echo $JAVA_HOME", it still display nothing.

Have you tried /etc/environment?

Does it add the export to /etc/environment:

Quote:

export JAVA_HOME=/usr/lib/j2sdk1.5-sun
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

Did you logout since making the change. The /etc/profile script is only executed if bash called interactively as a login shell. Are you sure you are using the bash shell? Check your entry in /etc/passwd. Also check that the --nologin option isn't present.

Section 6.2 of the bash info manual details which login scripts are executed, and under which circumstances.

I have tried it, but it still doesn't work.

There is no --nologin.

By the way, should the global evironment variables relate to the terminal type? I think they may not be related.

Try them in your ~/.bashrc then that should be getting executed on login just make sure this is set in your ~/.bash_profile.

Code:

# include .bashrc if it exists
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

No need to logout and back in for testing just use source ~/.bashrc to re-read the file in the current shell once everything is set then logout and back in.

Does tomcat run as a system user. If that is the case, you wouldn't set ~/.bashr or ~/.profile as a system user doesn't have a home directory. Also, it might be running in a jail. That means that the environment may be cleared out. If you have an /etc/profile.d/ directory, then put your "export

On some systems, there is an /etc/profile.d/ directory where you can add system wide shell startup scripts, such as a /etc/profile.d/tomcat.sh script. However, given your /etc/profile script, it doesn't appear to be the case.

I didn't notice a tomcat system user or a regular user in your /etc/passwd file. This may be a RTFM situation where you need to read through the tomcat installaton procedures more carefully.

Thank you. What you say is correct. But I let my tomcat auto-run. So, I need set the global environment variables to support it. When tomcat auto-run, the terminate's environment variables isn't initialized. This is mean the .bashrc environment work after tomcat auto-run, so tomcat can't find the evironment variables.

I use j2sdk for other applications besides tomcat. So I want to set global environment. But after I edit the /etc/profile and restart my computer, the java global environment doesn't work. I use 'echo $JAVA_HOME', there is nothing to display too. That confused me.

HappyTux · 10-26-2006, 09:49 PM

Well if everything else is not working then try putting the lines in the file /etc/init.d/bootmisc.sh near the bottom of the file above the exit 0, that is pretty much the last file run before the login happens. If needed sooner due to start up of the Tomcat make a file and put it in the /etc/init.d/ directory and make a symbolic link into the /etc/rc2.d/ directory with a number lower than the one that starts the Tomcat.

Thank you agian. Well, I give it up. My solution is add the JAVA environment variables to every header of applications startup shell script which use j2sdk.

It will be a puzzle that the /etc/profile doesn't work.

How does tomcat start. If there is a startup script, that would be a good place to set your JAVA environmental variables, before tomcat is started.
