I have installed the tomcat and Java on my Amazon EC2 Instance by followingthe instructions on the following tutorial. http://sites.google.com/site/amistrongeryet/setting-up-java-tomcat-on-ec2. But after installing when I run the "updatedb; locate javac | grep bin" command it did not recognize the update and locate command and gives me the error message locate: command not found and after installing the tomcat everything went sommoth during installation according to the instructions in above mentioned tutorial but at the end when I run the command "bin/startup.sh" and try to navigate the url http://my_public_dns_key:8080 it gives me the connection timed out error.

Also please find below the command reference for my linux commands that I am using to run Java and tomcat.

Command References:

Please provide any help that you can provide and help me to sort the issue out. Thanks in advance.

    In shell, which javac, what do you got? Command not found? Commented Sep 28, 2011 at 11:46
  • updatadb is just for you can use locate, you may refer the location of javac by system environment setting. Commented Sep 28, 2011 at 11:46
  • This is not an answer to your question but it might be a solution for your problem: take a look at Amazon's Elastic Beanstalk. Instead of a linux instance you get a tomcat instance. Commented Sep 28, 2011 at 11:48

Here are the steps I documented for myself in setting up java and tomcat in a 32 bit small instance. (lame that they support 32/64 bit on micro, but only 32 bit on small!)

Installing Tomcat

# make the directory that is going to hold tomcat sudo mkdir /opt/tomcat cd /opt/tomcat # download tomcat curl http://mirror.olnevhost.net/pub/apache/tomcat/tomcat-6/v6.0.29/bin/apache-tomcat-6.0.29.zip > tomcat6.zip unzip tomcat6.zip # now go into apache-tomcat-.../conf/server.xml and change all 8080 to 80 so we are running on the regular web port. # then start tomcat. sudo /opt/tomcat/apache-tomcat-.../bin/startup.sh

I later change it to use sudo wget http://apache.tradebit.com/pub/tomcat/tomcat-7/v7.0.16/bin/apache-tomcat-7.0.16.tar.gz

At this point, you should be able to hit http:/// and get the tomcat management page.

Installing Sun JDK 6 Download Sun JDK 6. You must agree to the terms and conditions in order to download, so I think you'll have to download and then sftp it over. I downloaded from http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u26-download-400750.html the 32 bit .bin version.

unzip the jdk into /opt/jdk1.6.xxx and then install it as a java alternative using the following:

sudo alternatives --install /usr/bin/java java /opt/jdk1.6.0_26/bin/java 1500 sudo alternatives --install /usr/lib/jvm/jre jre /opt/jdk1.6.0_26 1500 sudo alternatives --set java /opt/jdk1.6.0_26/bin/java sudo alternatives --set jre /opt/jdk1.6.0_26

Then make sure you are running java by checking java -version. Since tomcat will be starting as root, I used sudo to test it.

$ sudo java -version java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03) Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing)

  • Both the links for tomcat are dead. Please advice. Commented Sep 28, 2011 at 17:45
  • go to the tomcat download page and find whatever version you need and get the appropriate url from that download page. Commented Sep 28, 2011 at 19:12
  • I have done the following steps to install tomcat but no success 1- make the dir tomcat in opt 2- download the tomcat6 in tomcat folder 3- unzip the zip file in tomcat folder 4- do the necessary changes in conf/server.xml 5- run the bin/startup.sh file and it gives me the command not found.

  • make sure the script is executable and you have the correct path. Commented Sep 29, 2011 at 19:44

Have you checked that the security group of that instance allows inbound connections to port 8080

It looks as if Tomcat had started. Run

sudo fuser -v -n tcp 8080

It should output something like:

 USER PID ACCESS COMMAND 8080/tcp: tomcat pid F.... java

Then probe Tomcat right from the instance using wget or curl:

wget --spider localhost:8080

If you get 200 OK in response, it must be the firewall settings that prevent connection. Check your security group setting as David has already suggested - there must be a Custom TCP rule for port 8080.

You may also find it easier to install Java and Tomcat from the repo next time. There is a step-by-step guide for Amazon Linux in my article on Tomcat and EC2.
