Gosu not working under root (Linux 64-bit RH)

[Colin Hoad]

Hi,

 

I am trying to get Gosu up and running on a Linux 64-bit Red Hat server. I have followed the instructions, and edited the ~/.bashrc as instructed. When I run "gosu -version" under my own user account, I get the version number returned - as expected. However, when I sudo -su to root, I get the following:

 

[root@WHML30627 bin]# gosu -version
/usr/gosu/gosu-0.8.6.1-C/bin/gosu: line 4: dirname: command not found
/usr/gosu/gosu-0.8.6.1-C/bin/gosu: line 14: dirname: command not found
/usr/gosu/gosu-0.8.6.1-C/bin/gosu: line 15: readlink: command not found
ls: /../jars: No such file or directory
Exception in thread "main" java.lang.NoClassDefFoundError: gw/lang/shell/Gosu
Caused by: java.lang.ClassNotFoundException: gw.lang.shell.Gosu

        at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: gw.lang.shell.Gosu.  Program will exit.

 

Can anyone explain why root isn't happy running Gosu? I can run "java -version" when sudo'd to root, no problem. I have exactly the same entries in my ~/.bashrc for root as I have for my own user, so I don't understand why root isn't running Gosu.

 

Root's Bash profile:

# .bashrc

# User specific aliases and functions

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

export JAVA_HOME=/usr/java/jdk1.6.0_35
export GOSU_HOME=/usr/gosu/gosu-0.8.6.1-C
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin:$GOSU_HOME/bin

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

 

My user's bash profile:

# .bashrc

export JAVA_HOME=/usr/java/jdk1.6.0_35
export GOSU_HOME=/usr/gosu/gosu-0.8.6.1-C
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin:$GOSU_HOME/bin
# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

# User specific aliases and functions

 

 

Any ideas?

 

Thanks,

Colin

Seems like dirname and readlink aren't on your PATH for root.  Are you able to su to root, and run dirname and readlink manually from your command line?

If not, run the following, beginning as non-root, for more confirmation:

which dirname

which readlink

echo $PATH

sudo su - root

echo $PATH

Thank you very much, Brian - for some reason, root had "usr/bin" in its $PATH rather than "/usr/bin". As soon as I added "/usr/bin" to the $PATH it was happy running Gosu!

Thanks again,

Colin
