java - Tomcat 未在 Amazon EC2、Redhat 实例上运行

Question

我是一名java应用程序开发人员，对linux配置了解不多。

我正在尝试将 Java 和 Tomcat 安装到 Amazon EC2 上的新 Redhat 实例，并执行以下脚本。

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 # 

此时，http://ec2-23-20-24-96.compute-1.amazonaws.com:8080/预计会返回 Tomcat 主页，但它没有 :(

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

我将以下内容粘贴到文件中:

#!/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 $*

然后执行:

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

我没有得到任何错误，但我也无法显示 Tomcat 主页。 你能指导我哪里出错了吗。

谢谢

我的问题看起来与 https://forums.aws.amazon.com/thread.jspa?threadID=59937 上的问题相似, 但这没有提供任何解决方案。

我执行了一个 wget，我收到了一个带有 Tomcat 主页 html 的正确的 index.html。
wget http://ec2-23-20-24-96.compute-1.amazonaws.com:8080

我有两个安全组 - default 和 quick-start-1，我已将端口 80 和 8080 添加到列表中。

Answer 1

在 AWS Support 的帮助下解决了这个问题:

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
