sudo - Issue with environment variable

    Please help me running below command from user2 account. I cannot figure out what's the issue with this.

    [user2@localhost bin]# sudo -u user1 /opt/Tomcat/bin/shutdown.sh
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program
[user2@localhost bin]$ echo $JAVA_HOME
/opt/Java_7

    Entry for user2 in sudoers file is as below :

    %user2 ALL=(user1) NOPASSWD:/opt/Tomcat/bin/startup.sh,/opt/Tomcat/bin/shutdown.sh

    However the environment variables are set. I run the same script with root user and it works fine.

    [root@localhost bin]# /opt/Tomcat/bin/shutdown.sh
Using CATALINA_BASE:   /opt/Tomcat/
Using CATALINA_HOME:   /opt/Tomcat/
Using CATALINA_TMPDIR: /opt/Tomcat//temp
Using JRE_HOME:        /opt/Java_7
Using CLASSPATH:       /opt/Tomcat//bin/bootstrap.jar:/opt/Tomcat//bin/tomcat-juli.jar

    I have checked it further. JAVA_HOME is set for both the users.

    [root@localhost bin]# pwd
/opt/Tomcat/bin
[root@localhost bin]# echo $JAVA_HOME
/opt/Java_7
[root@localhost bin]# su user1
[user1@localhost bin]$ echo $JAVA_HOME
/opt/Java_7
[user1@localhost bin]$ exit
[root@localhost bin]# su user2
[user2@localhost bin]$ echo $JAVA_HOME
/opt/Java_7

[user2@localhost bin]$ ps aux | grep java

    To keep the JAVA_HOME environment variable when using sudo, you should add Defaults env_keep +="JAVA_HOME" to your sudoers file.

    If you use sudo -u user1, then neither the JAVA_HOME path of user2, nor the path of root will be used, you will need to set the JAVA_HOME path of user1. From the way it looks, you did not set the JAVA_HOME path of user1

    I am using Curl, and am having a problem trying to get it to recognize the $http_proxy environment variable when using sudo curl. I tried putting export http_proxy=.... in my /etc/profile and restarting the shell, to no avail. I would rather not use su -l and run the command while logged in as root.

    Look in /etc/sudoers. There is a list of environmental variables that get shared between sudo and the regular user shell

    You might need to add:

    envkeep http_proxy

    to your sudoers file. Check your sudo environmental variables by running:

    sudo -V

    as root. Or by running:

    sudo sudo -V
