我在笔记本电脑的 20GB 分区上运行 CentOS 6（适用于 32 位架构）。我尝试使用 java 8 安装 JBoss 7.1.1（JAVA_HOME=/usr/java/jdk1.8.0_152）。基本上我按照网上的步骤操作指导但现在当我以管理用户“jboss”的身份启动 Jboss 时，我无法通过 Firefox 访问服务器（“无法连接”）。但我知道服务器正在运行，CPU 以最大速度运行并ps -ef | grep jboss产生大量输出。当我尝试停止服务器时，我得到了
[jboss@centos jboss-as-7.1.1.Final]$ bin/jboss-cli.sh --connect command=:shutdown
org.jboss.as.cli.CliInitializationException: Failed to connect to the controller
at org.jboss.as.cli.impl.CliLauncher.initCommandContext(CliLauncher.java:22
[...output truncated...]
我怀疑iptables阻塞了流量，所以我为端口 8080 和 9990 设置了规则：
[dolly@centos opt]$ sudo iptables -L -n --line-numbers

不能telnet localhost 8080但可以ping localhost。这里是netstat：
[dolly@centos jboss-as-7.1.1.Final]$ netstat -napt | grep LISTEN
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)

仍然无法通过浏览器连接到应用服务器。知道可能是什么问题吗？
