如果我做了ps -ef | grep“java”,我看到以下参数.
-Dcom.sun.management.jmxremote.port=8084 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false
Netstat显示端口8084正在侦听0.0.0.0.在我的配置中,JMX设置为绑定到服务器的FQDN(我们使用私有DNS服务器).我的防火墙(IPTABLES / UFW)设置为允许所有传出流量,并允许端口8084上的传入流量.
服务器本身是虚拟的,有两个NIC,一个是公共的,一个是私有的.公共NIC的网关已禁用,因此连接只能在私有端进入.
当我尝试使用JMX将jvisualvm连接到我的应用服务器时,我在jvisualvm中收到以下错误.
Cannot connect to [FQDN OMITTED]:8084 using server:jmx:rmi:///jndi/rmi://[FQDN OMITTED]:8084/jmxrmi
如果我查看jvisualvm日志,我会看到以下跟踪.

有没有人有任何想法？
您可以为JMX和RMI对话指定 same port：-Dcom.sun.management.jmxremote.port=8084 -Dcom.sun.management.jmxremote.rmi.port=8084
