需要把原6.3.1版本升级为6.6.2版本
1，官网下载rpm包
2，升级elasticsearch和kibana
rpm -U elasticsearch-6.6.2.rpm rpm -U kibana-6.6.2-x86_64.rpm rpm -U logstash-6.6.2.rpm
配置还是使用原配置，新版本配置会在配置文件夹生成一个新的配置文件
cluster.name: my-elk node.name: dev-es-kibana path.data: /data/es-data path.logs: /var/log/elasticsearch bootstrap.memory_lock: false network.host: 0.0.0.0 http.port: 9200 #集群个节点IP地址，也可以使用els、els.shuaiguoxia.com等名称，需要各节点能够解析 #discovery.zen.ping.unicast.hosts: ["172.16.30.11","172.16.40.12"] #集群节点数 #discovery.zen.minimum_master_nodes: 2 #增加参数，使head插件可以访问es http.cors.enabled: true http.cors.allow-origin: "*"
server.port: 5601 server.host: "172.16.30.11" server.name: "dev-es-kinaba" elasticsearch.url: "http://172.16.30.11:9200" kibana.index: ".kibana"
重启
systemctl restart elasticsearch systemctl restart kibana
如果启动elastic报错
修改配置文件增加java家目录
/etc/sysconfig/elasticsearch
如果启动elasticsearch报插件版本不对的错误，把旧的插件remvoe掉重新安装一遍即可
/usr/share/elasticsearch/bin/elasticsearch-plugin remove ingest-geoip /usr/share/elasticsearch/bin/elasticsearch-plugin remove ingest-user-agent /usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-user-agent /usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-geoip
启动kibana访问报错
Kibana server is not ready yet
等待一会即可
升级成功
