Root PATH isn't right, can't change

crypted · 04-02-2010, 11:43 AM

After upgrading to CentOS 5.4, my root path seems screwed.

The issue is present for CRONJOBs that run as the root user as well as when I su to the user through SSH.

I need the following path ALWAYS:
PATH=/sbin:/usr/sbin:/bin:/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/X11R6/bin

It currently only gives root:
/usr/kerberos/sbin /usr/kerberos/bin /usr/local/bin /bin /usr/bin /usr/X11R6/bin

I have tried adding export PATH to the .bash_profile and set PATH = in the .tcshrc. Neither of those attempts work for my SSH session nor did it work for the root cronjob tasks.

Code:

# /root/ispconfig/php/php -q /root/ispconfig/scripts/writeconf.php
sh: httpd: command not found
ls: /conf.d/*.conf: No such file or directory
sh: httpd: command not found
start
sh: postmap: command not found
sh: httpd: command not found
Segmentation fault

The scripts were working just fine for two years. I haven't changed anything. Just stopped working after the upgrade. It's based upon the PATH issue though.

Any help is much appreciated!!!

What's in your .bash* files? How about the system wide defaults in /etc? You should be able to add:

export PATH=/sbin:/usr/sbin:/bin:/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/X11R6/bin

In several locations and get the changes you need.

Code:

# cat .bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:/bin:/usr/sbin:/sbin

export PATH
unset USERNAME

Code:

# cat .bashrc 
# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

Code:

 cat bashrc 
# /etc/bashrc

# System wide functions and aliases
# Environment stuff goes in /etc/profile

# By default, we want this to get set.
# Even for non-interactive, non-login shells.

        umask 002

I modified the .bash_profile but didn't work out. As far as SSH, I use TCSH as my shell. Always have.

This just started happening after the upgrade from 5.3 -> 5.4.

I added that line you gave me to all of those files above. I still don't get the proper path.

Does cron use your typical environment files? I didn't think that it did, I thought that you normally had to specify the full path in crontab entries and cron files. But that doesn't explain why it was working before and not now.

You mention that you don't get the correct path when you SSH in and that you use tcsh when you SSH. You also mention that you have edited various bash rc-files, however that isn't likely to make much difference if you are using tcsh.

Understood. I couldn't get my .tcsh customizations to work. So, I went to bash and the path seems okay for SSH. Now, I still have an issue with segmentation faults.

And, as I outlined in a new thread, most of the time my PHP sites only load as the PHP source text in the browser.
