????首先安裝好ELK，我使用的版本是5.6.10，HEAD，RabbitMQ，在RabbitMQ管理界面，創(chuàng)建Exchange ：ex_logstash，Queue：q_logstash，建立綁定，routing key是你的服務(wù)名稱。當(dāng)然也可以通過程序創(chuàng)建Exchange，Queue和綁定關(guān)系。然后按照如下步驟操作。

????一，在Spring Boot 2.0 項(xiàng)目pom.xml里添加RabbitMQ依賴，如下:

   <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-amqp</artifactId>
   </dependency>

????二，在logback.xml里配置如下

    <appender name="AMQP" class="org.springframework.amqp.rabbit.logback.AmqpAppender">
        <layout>
            <pattern>
                <![CDATA[%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50}.%method %line - %msg%n ]]>
            </pattern>
        </layout>
        <host>rabbitmq address</host>
        <port>5672</port>
        <username>user</username>
        <password>password</password>
        <applicationId>credit-card-bill</applicationId>
        <routingKeyPattern>credit-card-bill</routingKeyPattern>
        <declareExchange>true</declareExchange>
        <exchangeType>direct</exchangeType>
        <exchangeName>ex_logstash</exchangeName>
        <generateId>true</generateId>
        <charset>UTF-8</charset>
        <durable>true</durable>
        <deliveryMode>PERSISTENT</deliveryMode>
    </appender>

     <root level="INFO">
        <appender-ref ref="console" />
        <appender-ref ref="InfoRollingFile" />
        <appender-ref ref="AMQP" />
    </root>

????三，在logstash安裝目錄新建logstash.conf，配置如下

input {
    rabbitmq {
        host => "10.139.60.131"
        port => 5672
        user => kkuser
        password => kkuser123
        durable => true
        queue => "q_logstash"
        codec => plain
    }
} 

output {
    elasticsearch {
        hosts => ["http://127.0.0.1:9200"]
    }
}

????四，啟動(dòng)ELK，通過Head可以看到Logstash創(chuàng)建了以logstash-為前綴，后跟日期的索引。發(fā)起請(qǐng)求，產(chǎn)生日志，在Kibana界面中就能查看到日志了。
