Just got dropbox installed on my Ubuntu workstation. Great way to share files with my Mac and other computers. Now I cant live without it. To install on Jaunty just edit /etc/apt/sources.list and add:

deb http://linux.getdropbox.com/ubuntu jaunty main
deb-src http://linux.getdropbox.com/ubuntu jaunty main

Then:

$ sudo apt-get update
$ sudo apt-get install nautilus-dropbox

That’s it!!!

In order to have Tomcat listen on port 80, you either have to have it running as root (which by the way is not a very good idea), or configure a wrapper like JSCV.

Here is how you do it (This is an example using tomcat 6 please adapt to your install):

# cd /opt/apache-tomcat-6.0.16/bin/
# tar -zxvf jsvc.tar.gz
# cd jsvc-src
# chmod +x configure
# ./configure ; make
# cp jsvc ..

——————

Change your connection in server.xml to use port 80.

—————–

Start tomcat with a variation of the following init script:

tomcatjsvc.txt

As usual, let me know if you find any errors or a better way of doing it.

This is a step by step stand alone installation of Tomcat 6

JDK Install:

fetch JDK @ http://java.sun.com/

# sh jdk-6u4-linux-i586-rpm.bin
accept license

set java home and path:

# JAVA_HOME=/usr/java/jdk1.6.0_04/
# export JAVA_HOME
# PATH=$JAVA_HOME/bin:$PATH
# export PATH
# which java

Make it happen at boot time:

# cd /etc/profile.d
# vi /etc/profile.d/jdk.sh

add the following lines to jdk.sh:

export JAVA_HOME=/usr/java/jdk1.6.0_04/ #(or the the location to java home if different)
export PATH=$JAVA_HOME/bin:$PATH

Installing Tomcat From Binary:

wget http://www.signal42.com/mirrors/apache/tomcat/tomcat-6/v6.0.16/bin/apache-tomcat-6.0.16.tar.gz
Untar:
# tar -zxvf apache-tomcat-6.0.16.tar.gz

Move it to /opt/ or desired location
# mv apache-tomcat-6.0.16 /opt/

For security, lets make it run under a underprivileged user:
# useradd tomcat -d /opt/apache-tomcat-6.0.16/temp/

Adjust permissions:
# chown -R tomcat:tomcat /opt/apache-tomcat-6.0.16/

Test install
[root@localhost opt]# sudo -u tomcat /opt/apache-tomcat-6.0.16/bin/startup.sh

or use startup script:

#vi /etc/init.d/tomcat

use the following script:

http://www.linuxzone.org/scripts/tomcat.txt

Add it to chkconfig and turn it on:

# chkconfig --add tomcat
# chkconfig tomcat on

That is it! Let me know if missed anything.
