elasticsearch|大数据|kibana的安装（https+密码）

前言：

kibana是比较好安装的，但https+密码就比较麻烦一些了，下面将就如何安装一个可在生产使用的kibana做一个简单的讲述

一，

kibana版本和下载地址

这里我想还是强调一下，kibana的版本需要和elasticsearch的版本一致，小版本都不能差，否则，kibana将不能正确连接到elasticsearch

本例我使用的是elasticsearch-6.3.2版本，因此，下载的kibana版本也是6.3.2

官方下载地址：

Kibana 6.3.2 | Elastic

两个版本二进制和rpm基本没有什么区别，想折腾点就二进制了，不想太麻烦rpm即可，看自己的需求啦。

不过要吐槽一下，官网下载比较慢，即使科学上网仍然很慢，因此，是需要一点耐心了

下载完毕后，没什么好说的，扔到服务器上就可以了

二，

elasticsearch的证书

kibana是安装在192.168.123.15上面的（kibana是node项目，可以安装在任意的服务器上，不需要配置node环境）

elasticsearch|大数据|elasticsearch的api部分实战操作以及用户和密码的管理-CSDN博客?这个是elasticsearch集群的https开启，部署的时候没有添加192.168.123.15，因此，重新生成证书：

[root@node4 ~]# cat instances.yml 
instances:
  - name: "node-1"
    dns: ['192.168.123.11']
  - name: "node-2"
    dns: ['192.168.123.12']
  - name: "node-3"
    dns: ['192.168.123.13']    
  - name: 'node-4'
    dns: ['192.168.123.14']
  - name: 'node-5'
    dns: ['192.168.123.15']

执行以下命令生成证书包：

###注：生成的证书格式是pem的，可以直接使用，无需任何转换（哪个服务器都可以，随便找个服务器就可以了）

/data/es/bin/x-pack/certutil cert ca --pem --in instances.yml --out /root/certs.zip
解压上面在root根目录下生成的证书包

在15服务器上，证书放置在此目录下/opt/kibana/（kibana整个也是放置在opt目录下的，二进制方式部署）：

[root@centos5 kibana]# ls -al ca.crt node-5.crt node-5.key 
-rw-r--r-- 1 root root 1200 Dec 15 23:07 ca.crt
-rw-r--r-- 1 root root 1180 Dec 15 23:07 node-5.crt
-rw-r--r-- 1 root root 1679 Dec 15 23:07 node-5.key

证书重新分发到elasticsearch集群，然后重启elasticsearch集群??

kibana的配置文件：

####注意，密码必须双引号包裹，否则kibana识别不了，会报错，其次是elasticsearch.url?的值是elasticsearch集群的任意一个节点URL就可以了，不需要全部节点都列出

####elasticsearch.ssl.verificationMode: certificate?和elasticsearch的设置一致

[root@centos5 kibana]# cat config/kibana.yml 
# Kibana is served by a back end server. This setting specifies the port to use.
server.port: 15666

# 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: 192.168.123.15

# 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

# The Kibana server's name.  This is used for display purposes.
server.name: mykibana

# The URL of the Elasticsearch instance to use for all your queries.
elasticsearch.url: https://192.168.123.11:19200

# When this setting's value is true Kibana uses the hostname specified in the server.host
# setting. When the value of this setting is false, Kibana uses the hostname of the host
# that connects to this Kibana instance.
#elasticsearch.preserveHost: true

# Kibana uses an index in Elasticsearch to store saved searches, visualizations and
# dashboards. Kibana creates a new index if the index doesn't already exist.
#kibana.index: ".kibana"

# The default application to load.
#kibana.defaultAppId: "home"

# If your Elasticsearch is protected with basic authentication, these settings provide
# the username and password that the Kibana server uses to perform maintenance on the Kibana
# index at startup. Your Kibana users still need to authenticate with Elasticsearch, which
# is proxied through the Kibana server.
elasticsearch.username: elastic
elasticsearch.password: "123456"

# Enables SSL and paths to the PEM-format SSL certificate and SSL key files, respectively.
# These settings enable SSL for outgoing requests from the Kibana server to the browser.
server.ssl.enabled: true
server.ssl.certificate: /opt/kibana/node-5.crt
server.ssl.key: /opt/kibana/node-5.key

# Optional settings that provide the paths to the PEM-format SSL certificate and key files.
# These files validate that your Elasticsearch backend uses the same key files.
#elasticsearch.ssl.certificate: /path/to/your/client.crt
#elasticsearch.ssl.key: /path/to/your/client.key

# Optional setting that enables you to specify a path to the PEM file for the certificate
# authority for your Elasticsearch instance.
elasticsearch.ssl.certificateAuthorities: [ "/opt/kibana/ca.crt" ]

# To disregard the validity of SSL certificates, change this setting's value to 'none'.
elasticsearch.ssl.verificationMode: certificate

# Time in milliseconds to wait for Elasticsearch to respond to pings. Defaults to the value of
# the elasticsearch.requestTimeout setting.
#elasticsearch.pingTimeout: 1500

# Time in milliseconds to wait for responses from the back end or Elasticsearch. This value
# must be a positive integer.
#elasticsearch.requestTimeout: 30000

# List of Kibana client-side headers to send to Elasticsearch. To send *no* client-side
# headers, set this value to [] (an empty list).
#elasticsearch.requestHeadersWhitelist: [ authorization ]

# Header names and values that are sent to Elasticsearch. Any custom headers cannot be overwritten
# by client-side headers, regardless of the elasticsearch.requestHeadersWhitelist configuration.
#elasticsearch.customHeaders: {}

# Time in milliseconds for Elasticsearch to wait for responses from shards. Set to 0 to disable.
#elasticsearch.shardTimeout: 30000

# Time in milliseconds to wait for Elasticsearch at Kibana startup before retrying.
#elasticsearch.startupTimeout: 5000

# Logs queries sent to Elasticsearch. Requires logging.verbose set to true.
#elasticsearch.logQueries: false

# Specifies the path where Kibana creates the process ID file.
#pid.file: /var/run/kibana.pid

# Enables you specify a file where Kibana stores log output.
logging.dest: /var/log/kibana/kibana.log

# Set the value of this setting to true to suppress all logging output.
#logging.silent: false

# Set the value of this setting to true to suppress all logging output other than error messages.
#logging.quiet: false

# Set the value of this setting to true to log all events, including system usage information
# and all requests.
#logging.verbose: false

# Set the interval in milliseconds to sample system and process performance
# metrics. Minimum is 100ms. Defaults to 5000.
#ops.interval: 5000

# The default locale. This locale can be used in certain circumstances to substitute any missing
# translations.
i18n.defaultLocale: "zh-CN"

根据配置文件，创建目录（kibana.log文件会自动生成）：

mkdir /var/log/kibana

三，

启动kibana

/opt/kibana/bin/kibana

此时是前台启动，直接看日志：

###提示kibana的版本是6.3.2，但elasticsearch的版本是6.2.4版本，
