在这里插入图片描述

报错原因：kibana启动时，需要连接es的9200端口，而es还没有启动。
解决办法：
1、
查找kibana进程以及端口

ps -ef|grep kibana

ps -ef|grep 5601

都找不到

尝试使用 fuser -n tcp 5601

kill -9  端口

启动即可 ./kibana

或者
启动ES,之后再启动kibana，kibana启动时，需要连接es的9200端口

方法2、

不要看ｋｉｂａｎａ的日志，看ｅｓ的日志，设置ｃｌｕｓｔｅｒ和ｎｏｄｅ名就可以了

root@jnydjky:/optlim/elasticsearch-6.2.3# cd config/
root@jnydjky:/optlim/elasticsearch-6.2.3/config# ls
elasticsearch.yml  elasticsearch.yml1  jvm.options  log4j2.properties
root@jnydjky:/optlim/elasticsearch-6.2.3/config# 
root@jnydjky:/optlim/elasticsearch-6.2.3/config# vi elasticsearch.yml

#注意空格
cluster.name: jnydjky
node.name: jnydjky

解决办法：

报错3、启动logstash报错 Unrecognized VM option ‘UseParNewGC’

解决措施：删去config文件夹下的jvm.options配置文件中的-XX:UseParNewGC
