CenttOS 6.6下部署ELK日志告警系统(5)

2018-04-25T09:14:55.592+0800    INFO    kafka/log.go:36    Failed to connect to broker [[localhost:9092 dial tcp [::1]:9092: getsockopt: connection refused]]: %!s(MISSING)

日志出现两个地址，一个是kafka地址，另外出现一个localhost地址。
这是因为filebeat已经跟kafaka建立了连接，但是从kafaka到zookeeper这一段找不到

解决方法

# get /brokers/ids/0
{"listener_security_protocol_map":{"PLAINTEXT":"PLAINTEXT"},"endpoints":["PLAINTEXT://localhost:9092"],"jmx_port":-1,"host":"localhost","timestamp":"1523429158364","port":9092,"version":4}
cZxid = 0x1d
ctime = Wed Apr 11 14:45:58 CST 2018
mZxid = 0x1d
mtime = Wed Apr 11 14:45:58 CST 2018
pZxid = 0x1d
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x162b374170d0000
dataLength = 188
numChildren = 0

# 发现注册地址是localhost,修改之
set /brokers/ids/0  {"listener_security_protocol_map":{"PLAINTEXT":"PLAINTEXT"},"endpoints":["PLAINTEXT://kafkaNode:9092"],"jmx_port":9999,"host":"kafkaNode","timestamp":"1523429158364","port":9092,"version":4}

修改完重启，问题解决。
