Kibana简介
Kibana 是一个免费且开放的用户界面，能够让您对 Elasticsearch 数据进行可视化，并让您在 Elastic Stack 中进行导航。您可以进行各种操作，从跟踪查询负载，到理解请求如何流经您的整个应用，都能轻松完成。
- Kibana是ElasticSearch的一个工具，用来分析ES中的数据并以各种图形界面显示出来
- 可以作为ElasticSearch的一个客户端，在Kibana中可以很轻松的调用ES的RESTful接口
下载地址
https://elasticsearch.cn/download/
https://artifacts.elastic.co/downloads/kibana/kibana-7.6.0-linux-x86_64.tar.gz
系统版本：CentOS Linux release 7.3.1611 (Core)
安装
下载压缩包并解压之后，需要关注两个文件夹，一个是config文件夹，里面的kibana.yml是配置文件；一个是bin文件夹，里面有kibana启动的bat脚本
上传kibana-7.6.0-linux-x86_64.tar.gz文件到 /opt目录下，并解压
tar -zxvf kibana-7.6.0-linux-x86_64.tar.gz
在目录/usr/local下创建目录：kibana-7.6.0
mkdir kibana-7.6.0
复制解压后的文件到/usr/local/kibana-7.6.0目录下
cp -R /opt/kibana-7.6.0-linux-x86_64/* /usr/local/kibana-7.6.0/
设置 kibana-7.6.0目录权限给elasticsearch用户
chown -R elasticsearch:elasticsearch kibana-7.6.0/
设置配置文件
修改/usr/local/kibana-7.6.0/config/kibana.yml
设置ElasticSearch的访问地址：
elasticsearch.hosts: ["http://192.168.8.190:9200"]
设置Kibana的访问地址，如果不设置则只能本机访问。
server.host: "192.168.8.190"
# Kibana is served by a back end server. This setting specifies the port to use. #server.port: 5601 # Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values. # The default is 'localhost', which usually means remote machines will not be able to connect. # To allow connections from remote users, set this parameter to a non-loopback address. server.host: "192.168.8.190" # Enables you to specify a path to mount Kibana at if you are running behind a proxy. # Use the `server.rewriteBasePath` setting to tell Kibana if it should remove the basePath # from requests it receives, and to prevent a deprecation warning at startup. # This setting cannot end in a slash. #server.basePath: "" # Specifies whether Kibana should rewrite requests that are prefixed with # `server.basePath` or require that they are rewritten by your reverse proxy. # This setting was effectively always `false` before Kibana 6.3 and will # default to `true` starting in Kibana 7.0. #server.rewriteBasePath: false # The maximum payload size in bytes for incoming server requests. #server.maxPayloadBytes: 1048576 # Kibana is served by a back end server.

启动
如果用root用户启动会报错：
Kibana should not be run as root. Use --allow-root to continue.切换elasticsearch用户，并进入目录：/usr/local/kibana-7.6.0/bin 启动服务
./kibana
当看到以下提示信息，说明启动成功

设置开机启动
建立服务文件
vi /lib/systemd/system/kibana.service
[Unit] Description=Kibana [Service] LimitNOFILE=100000 LimitNPROC=100000 ExecStart=/usr/local/kibana-7.6.0/bin/kibana User=elasticsearch Group=elasticsearch [Install] WantedBy=multi-user.target
设置开机自启动
重新加载systemd的守护线程：systemctl daemon-reload
systemctl enable kibana其他
启动elasticsearch.service：
systemctl start kibana.service
查看kibana.serivce状态：
systemctl status kibana.service ps aux|grep kibana
如果出现错误可以使用如下命令查看日志：journalctl -u kibana.service
