CENTOS7 JGROUPS JGRP000029问题

:JGRP000029: localhost-34428: failed sending message to cluster

处理办法:

1)在tomcat中增加 -Djava.net.preferIPv4Stack=true参数

2)修改防火墙配置,增加udp端口为45588

firewall-cmd --permanent --zone=public --add-port=45588/udp

firewall-cmd --reload

终于看到久违的信息了。

Group Members Changed, LIST: localhost-19729,xiong-PC-45702
