ELK+redis配置

---------------------------------------------------------ELK日誌應用調整地方-----------------------------------------------------------------------------

應用每個服務新增logback-spring.xml檔案，新增配置：

<appender name="logstash" class="com.cwbase.logback.RedisAppender">
    <host>192.168.6.115</host> <!--redis資料庫伺服器IP-->
	<port>6379</port>   <!--redis資料庫埠-->
	<database>10</database> <!--redis資料庫-->
	<key>gzl-log</key>  <!-- 這個Key是Redis List的Key，需要和Logstash讀取Redis的Key匹配 -->
	<source>${appName}</source> <!--索引位，取別不同應用-->
</appender>

<springProfile name="dev">
	<!-- 開發環境時啟用，具體模式根據實際環境配置編寫-->
	<root level="info">
		<appender-ref ref="STDOUT" />
		<appender-ref ref="syslog" />
		<appender-ref ref="logstash"/><!--新增logstash-->
	</root>
</springProfile>
 

在base基礎模組新增依賴：

<dependency>
	<groupId>com.cwbase</groupId>
	<artifactId>logback-redis-appender</artifactId>
	<version>1.1.6</version>
</dependency>
<dependency>
	<groupId>ch.qos.logback</groupId>
	<artifactId>logback-core</artifactId>
</dependency>
<dependency>
	<groupId>ch.qos.logback</groupId>
	<artifactId>logback-classic</artifactId>
</dependency>
 

-------------------------------------------------------------ELK搭建配置-------------------------------------------------------------------

效果：

logstash安裝：

在logstash/config目錄下新增配置檔案：logstash-redis.conf，內容如下：

input {
    # redis外掛為常用外掛，外掛內選項很多，可根據需求自行判斷
    redis {
        # EVAL命令返回的事件數目，設定為5表示一次請求返回5條日誌資訊
        batch_count => 1 
        # logstash redis外掛工作方式
        data_type => "list" 
        # 監聽的鍵值
        key => "gzl-log" 
        # redis地址
        host => "192.168.6.115" 
        # redis埠號
        port => 6379 
        # 如果有安全認證，此項為認證密碼，若沒有則刪除改行
        password => 
        # 如果應用使用了不同的資料庫，此為redis資料庫的編號，預設為0。
        db => 10 
       # 啟用執行緒數量
        threads => 1000
      }
}
output {
     #可以同時輸出到多個終端
     #篩選過濾後的內容輸出到終端顯示
     #tdout { codec => "rubydebug" }
     #匯出到elasticsearch
     elasticsearch {
        # 匯出格式為json
        codec => "json"
        # ES地址+埠
        hosts => ["192.168.6.115:9200"]
        # 設定索引，可以使用時間變數
        index => "logstash-slow-%{+YYYY.MM.dd}"
        # ES如果有安全認證就使用賬號密碼驗證，無安全認證就不需要
     }   
}
 

elasticsearch安裝： 

在elasticsearch/config目錄下修改配置檔案：elasticsearch.yml，內容如下：

# ======================== 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 -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: gzl-log
#
# 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: /opt/data
#
# Path to log files:
#
path.logs: /opt/logs
#
# ----------------------------------- 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: kafka
#
# 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: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes: 
#
# 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
http.cors.enabled: true          
http.cors.allow-origin: "*"        
bootstrap.memory_lock: false
bootstrap.system_call_filter: false

kibana安裝：

在kibana/config目錄下修改配置檔案：kibana.yml，內容如下：

# 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: "kafka"

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

# 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: false
#server.ssl.certificate: /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.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: [ "/path/to/your/CA.pem" ]

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

# 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

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