Tomcat無法在Amazon EC2，Redhat實例上運行

Question

我是一名java應用程序開發人員，對linux配置知之甚少。

我正在嘗試將Java和Tomcat安裝到Amazon EC2上的新Redhat實例上，並執行以下腳本。

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 # 

此時， http：//ec2-23-20-24-96.compute-1.amazonaws.com:8080/有望返回Tomcat主頁，但它沒有:(

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

我將以下內容粘貼到文件中：

#!/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 $*

然后執行：

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

我沒有收到任何錯誤，但我也無法顯示Tomcat主頁。 你能指導我哪里出錯嗎？

謝謝

EDIT2：

我的問題看起來類似於https://forums.aws.amazon.com/thread.jspa?threadID=59937上的問題 ，但這沒有提供任何解決方案。

我執行了一個wget，然后我收到了一個帶有Tomcat主頁html的正確index.html。
wget http://ec2-23-20-24-96.compute-1.amazonaws.com:8080

我有兩個安全組 - 默認和快速啟動-1，我已經將端口80和8080添加到列表中。

Answer 1

在AWS Support的幫助下解決了這個問題：

你好

它最初看起來像iptables在你的實例上運行，我的檢查顯示過濾端口，你需要添加規則以允許端口8080，或者禁用實例本身的防火牆。

您可以通過以root“ service iptables stop ”運行來驗證這一點，然后查看是否可以在端口8080上連接。

親切的問候
