Tomcat无法在Amazon EC2，Redhat实例上运行

Question

I'm a java application developer, and don't know much about linux configuration.

I'm trying to install Java and Tomcat to a fresh Redhat instance on Amazon EC2, and executed the below script.

mkdir /usr/local/java
cd /usr/local/java
curl http://download.oracle.com/otn-pub/java/jdk/7u2-b13/jdk-7u2-linux-i586.rpm > jdk.rpm
rpm -iv jdk.rpm

updatedb; locate javac | grep bin  # this step merely serves to verify the installation
/usr/sbin/alternatives --install /usr/bin/java java /usr/java/jdk1.7.0_02/bin/java 100
/usr/sbin/alternatives --install /usr/bin/jar jar /usr/java/jdk1.7.0_02/bin/jar 100
/usr/sbin/alternatives --install /usr/bin/javac javac /usr/java/jdk1.7.0_02/bin/javac 100
/usr/sbin/alternatives --config java
updatedb

mkdir /env
mkdir /env/tomcat
cd /env/tomcat
curl http://www.gtlib.gatech.edu/pub/apache/tomcat/tomcat-7/v7.0.23/bin/apache-tomcat-7.0.23.tar.gz > apache-tomcat-7.0.23.tar.gz
tar zxvf apache-tomcat-7.0.23.tar.gz
cd apache-tomcat-7.0.23
bin/startup.sh # 

At this point, http://ec2-23-20-24-96.compute-1.amazonaws.com:8080/ was expected to return Tomcat homepage, but it didn't :(

cd /etc/rc.d/init.d/
vi tomcat

I pasted the below content to the file:

#!/bin/sh
# Tomcat init script for Linux.
#
# chkconfig: 2345 96 14
# description: The Apache Tomcat servlet/JSP container.

JAVA_HOME=/usr/java/jdk1.7.0_02
CATALINA_HOME=/env/tomcat/apache-tomcat-7.0.23
export JAVA_HOME CATALINA_HOME

exec $CATALINA_HOME/bin/catalina.sh $*

Then executed:

chmod 755 /etc/rc.d/init.d/tomcat
chkconfig --level 2345 tomcat on

export JAVA_HOME=/usr/java/jdk1.7.0_02
export PATH=$PATH:/usr/java/jdk1.7.0_02
export CATALINA_HOME=/env/tomcat/apache-tomcat-7.0.23

/env/tomcat/apache-tomcat-7.0.23/bin/shutdown.sh
/env/tomcat/apache-tomcat-7.0.23/bin/startup.sh

Nowhere did I get any error, but I also couldn't get the Tomcat homepage to display. Can you guide where where I went wrong.

Thanks
James

EDIT2:

My problem looks similar to the one on https://forums.aws.amazon.com/thread.jspa?threadID=59937 , but that provides no solution.

I performed a wget, and I received a proper index.html with Tomcat homepage html.
wget http://ec2-23-20-24-96.compute-1.amazonaws.com:8080

I have two security groups - default and quick-start-1, and I've added ports 80 and 8080 to the list.

Answer 1

Solved it with help from AWS Support:

Hello

It initially looks like iptables is running on your instance, my checks show filtered ports, you will need to add a rule to allow port 8080, or disable the firewall on the instance itself.

You can verify this by running as root " service iptables stop " and then see if you can connect on port 8080.

Kind Regards
