centos6.4 JBoss7.1修改端口为80报错

今天把JBoss默认的8080端口改成80端口，具体修改方法是：修改配置文件$JBOSS_HOME\standalone\configuration\standalone.xml

找到如下到配置信息，并把8080改成，见红色字体部分

<socket-binding-group name="standard-sockets" default-interface="any" port-offset="${jboss.socket.binding.port-offset:0}">
        <socket-binding name="management-native" interface="management" port="${jboss.management.native.port:9999}"/>
        <socket-binding name="management-http" interface="management" port="${jboss.management.http.port:9990}"/>
        <socket-binding name="management-https" interface="management" port="${jboss.management.https.port:9443}"/>
        <socket-binding name="ajp" port="8009"/>
        <socket-binding name="http" port="80"/>
        <socket-binding name="https" port="8443"/>
        <socket-binding name="osgi-http" interface="management" port="8090"/>
        <socket-binding name="remoting" port="4447"/>
        <socket-binding name="txn-recovery-environment" port="4712"/>
        <socket-binding name="txn-status-manager" port="4713"/>
        <outbound-socket-binding name="mail-smtp">
            <remote-destination host="localhost" port="25"/>
        </outbound-socket-binding>
    </socket-binding-group>

修改完后，报错，启动JBoss7.1报错，如下：

这是因为linux的端口0-1024的端口只有root用户才能使用，改成用root用户进入终端，启动jboss，启动不报错了，80端口也能访问
