Activemq JBoss A-MQ 6.1的Red Hat 7:无法访问管理控制台

我们遇到了和这篇文章相同的问题：，但是那篇文章没有说明他是如何解决这个问题的

我们正在尝试评估JBoss A-MQ，并根据他们的要求安装了带有A-MQ 6.1的RHEL 7。一切都在本地运行，例如，样本生产者/消费者测试成功验证了安装步骤

但是，即使配置了远程用户，我们也无法访问管理控制台。我们必须向setenv添加一个JAVA_OPTIONS条目来覆盖默认的IPv6套接字，而netstat显示服务现在正在侦听tcp套接字，而不是tcp6：

File /opt/jboss-a-mq-6.1.0.redhat-379/bin/setenv now contains:
JAVA_OPTS="$JAVA_OPTS -Djava.net.preferIPv4Stack=true"
export JAVA_OPTS

# netstat -paunt | grep 8181
tcp        0      0 0.0.0.0:8181            0.0.0.0:*               LISTEN      10698/java

我们可以从其他系统ping该框，但是尝试在端口8181上打开telnet会话时超时。我们尝试过的管理控制台URL有：

http://172.16.100.110:8181/hawtio
http://172.16.100.110:8181

但两者都不起作用我们错过了什么？

以下是amq.log中包含hawt的条目，看起来它正在正确启动：

天哪，这是本地服务器上的防火墙

在花了一天的时间在网络上搜寻想法，试图找出我的配置出了什么问题之后，在绝望中，我终于认为我应该尝试禁用防火墙，看看会发生什么。所以我用命令关闭了它：

sudo service firewalld stop

突然我可以访问管理控制台了！我尝试了默认的URL，它成功了：

http://172.16.100.110:8181

哦
