java - zabbix服务器无法连接到java网关

Question

我已经在同一个 linux 服务器上安装了 zabbix server 和 java gateway 并启动了 zabbix-server 和 zabbix-java-gateway 服务。 OS为CentOS 6.5，java为JDK1.6.0_45，IP为192.98.12.240，zabbix server和zabbix java gateway版本为2.2.9。我已经停止了 iptables 服务。

然后在zabbix web控制台，我添加了一个启用了jmx接口(interface)的主机。我的主机 IP 是 192.98.12.198，JMX post 是 9999。在 Jconsole 中，我可以连接到这个启用 JMX 的 java 应用程序。但是在 zabbix web console 中，它显示错误:

下面是我的zabbix_server.conf

下面是我的zabbix_java_gateway.conf

请帮忙，谢谢。

ps:我把zabbix_server.conf里面的JavaGateway改成了localhost或者127.0.0.1，也没用。

Answer 1

# 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 没有阻止请求。
