【Elasticsearch】Elasticsearch+Kibana安装记录Elasticsearch需要安装一个集群

1、配置环境

1.1、软件

安装Elasticsearch需要安装如下软件：

JDK 1.8；

Elasticsearch-5.2.2；

Kibana-5.2.2；

x-pack（Elasticsearch和kibana的插件）；

安装分析器插件（elasticsearch-analysis-ik-5.2.2、elasticsearch-analysis-pinyin-5.2.2）；

2、JDK 1.8的安装

安装JDK 1.8，并配置好环境变量；

3、Elasticsearch-5.2.2的安装

　　Elasticsearch需要安装一个集群3个节点，3分别装在3台物理机上，下面是其中一个节点的安装，其他节点同理，只是配置有些许不一样，其中集群是通过配置的集群名称进行指定的。
注意：由于Elasticsearch不能以root账号启动，所以需要专门建一个账号对其进行安装启动和管理，包括其日志路径和数据路径都的权限都赋予该用户。

Elasticsearch和其插件的安装步骤如下：

将提供的安装包，解压到安装路径$ES_HOME；

将elasticsearch-analysis-ik-5.2.2解压到$ES_HOME/plugins/analysis-ik；

将elasticsearch-analysis-pinyin-5.2.2解压到$ES_HOME/plugins/analysis-pinyin；

安装x-pack，执行$ES_HOME/bin/elasticsearch-plugin install x-pack；

上面的步骤完成之后，需要修改配置文件，修改的内容如下：

cluster.name: es_cluster；

node.name: node-xxx（最好是端口或者ip具有标识作用）；

path.data：xxx（Elasticsearch数据存储路径）；

path.logs：xxx（Elasticsearch日志存储路径）；

network.host：xxx.xxx.xxx.xxx（本机区域网内的ip，用于集群内通讯）；

http.port：9200（http接口，其他rest api 请求操作使用到）；

discovery.zen.ping.unicast.hosts: ["192.168.0.50:9300", "192.168.0.50:9301", "192.168.0.50:9301"]（其他节电的ip和地址，此处作为参考（同一台物理机部署多个节点端口不能一致）；

action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history* (x-pack插件需要自动创建一些索引，需要使用到)；

测试环境的配置文件参考如下：

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------

#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: es_cluster
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1

node.max_local_storage_nodes: 16
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /data/elk/data/elasticsearch
#
# Path to log files:
#
path.logs: /data/elk/logs/elasticsearch
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 192.168.0.50
#
# Set a custom port for HTTP:
#
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
discovery.zen.ping.unicast.hosts: ["192.168.0.50:9300", "192.168.0.50:9301", "192.168.0.50:9301"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes: 3
#
# For more information, consult the zen discovery module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true

action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*

安装完成之后，需要通过 nohup $ES_HOME/bin/elasticsearch & 后台启动，启动完成之后，访问http://hostip:port/，如测试环境为http://192.168.0.50:9200/，如果返回如下内容表示安装成功：

{
  "name" : "node-1",
  "cluster_name" : "es_cluster",
  "cluster_uuid" : "Sps6AGSdQWWm9w3Ttb3pEQ",
  "version" : {
    "number" : "5.2.2",
    "build_hash" : "f9d9b74",
    "build_date" : "2017-02-24T17:26:45.835Z",
    "build_snapshot" : false,
    "lucene_version" : "6.4.1"
  },
  "tagline" : "You Know, for Search"
}

4、Kibana-5.2.2的安装

　　Kibana只是用于管理，查看Elasticsearch的一个软件，安装一个节点即可，具体的安装步骤如下：

将提供的安装包，解压到安装路径$KIBANA_HOME；

使用 $KIBANA_HOME/bin/kibana-plugin install x-pack 命令安装x-pack插件，过程比较久，需要耐心等待；

修改配置文件；

具体的配置文件修改如下：

server.host: "0.0.0.0"；

elasticsearch.url:http://hostip:port（任意一个Elasticsearch节点即可）；

测试环境的配置文件如下：

# 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: "0.0.0.0"

# Enables you to specify a path to mount Kibana at if you are running behind a proxy. This only affects
# the URLs generated by Kibana, your proxy is expected to remove the basePath value before forwarding requests
# to Kibana. This setting cannot end in a slash.
#server.basePath: ""

# 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: "your-hostname"

# The URL of the Elasticsearch instance to use for all your queries.
elasticsearch.url: "http://192.168.0.50:9200"

# 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: "discover"

# 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: "user"
#elasticsearch.password: "pass"

# Paths to the PEM-format SSL certificate and SSL key files, respectively. These
# files enable SSL for outgoing requests from the Kibana server to the browser.
#server.ssl.cert: /path/to/your/server.crt
#server.ssl.key: /path/to/your/server.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.cert: /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.ca: /path/to/your/CA.pem

# To disregard the validity of SSL certificates, change this setting's value to false.
#elasticsearch.ssl.verify: true

# 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: 0

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

# 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: stdout

# 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

安装完成之后，需要使用命令nohup $KIBANA_HOME/bin/kibana & 后台启动，启动完成后，反问http://hostip:5601即可，由于安装了x-pack需要用户名和密码，默认为elastic:changeme。后续需要修改可以直接在kibana的管理后台进行修改；

注意：kibana后台启动后，不能查出其线程，所以不能直接通过kill进行关闭，需要如下命令进行关闭。

具体命令如下；

fuser -n tcp 5601
# fuser -n tcp 5601 该命令会返回一个端口
kill -9 port
