zabbix服务器可以'；t连接到java网关

我已经在同一台linux服务器上安装了zabbix服务器和java网关，并启动了zabbix服务器和zabbix java网关服务。操作系统是CentOS 6.5，java是JDK1.6.045，IP是192.98.12.240，zabbix服务器和zabbix java网关版本是2.2.9。我停止了iptables服务

然后在zabbix web控制台中，我添加了一个启用jmx接口的主机。我的主机IP是192.98.12.198，JMX post是9999。在Jconsole中，我可以连接到这个支持JMX的java应用程序。但在zabbix web控制台中，它显示错误：

下面是我的zabbix_server.conf

请帮忙，谢谢

ps：我已经将zabbix_server.conf中的JavaGateway更改为localhost或127.0.0.1，我也没有工作

# Modify zabbix_server.conf


JavaGateway=127.0.0.1

# Modify zabbix_java_gateway.conf

LISTEN_IP=127.0.0.1

# Restart Services 
service zabbix-server restart

service zabbix-java-gateway restart

注意：确保SELinux或iptables不会阻止请求。

我自己找到了解决方案。

添加-Djava.net.preferIPv4Stack=true到VM选项解决问题

根据错误消息“无法连接到[[192.98.12.240]：10052]：[13]权限被拒绝”，Zabbix服务器不允许连接到Java网关。请检查您是否可以手动建立连接，以及是否没有类似SELinux的东西阻止该连接？
