2023-06-19 15:01:37 作者：我高考零分!

这篇文章主要介绍了Linux下如何安装Logstash问题，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教

一、安装Logstash

1.解压tar包

cd /data/app/elk/elk-6.8.5
tar zxvf logstash-6.8.5.tar.gz

2.配置config目录下的logstash.conf

# 数据输入部分
input {
    # 读取nginx访问日志
    file {
		#path：监听文件的路径,绝对路径
        path => "/data/app/nginx/logs/access.log" #为Nginx的access.log路径
		# 格式：json
        codec => "json"
		#start_position:监听文件的起始位置，beginning：从文件的头开始读取
        start_position => "beginning"
		#type：自定义类型
        type => "nginx-access-log"
    }
    # 读取nginx异常日志
    file {
        path => "/data/app/nginx/logs/error.log" #为Nginx的error.log路径
        # 格式：plain,输入的是字符串，输出把全部内容放到message字段
        codec => "plain"
        start_position => "beginning"
        type => "nginx-error-log"
    }
	#filebeats方式	
	beats {
		port => 5044
        type => "beats_log"
	}
	#自定义端口，一个项目可对应一个自定义tcp端口接收数据
	tcp {
		mode => "server"
		host => "192.168.X.X" #IP地址
		port => 21022
		codec => json
		type => "application-log" #application一般为项目名称
	}
}
# 数据处理部分
filter{
	if[type] == "application-log"{
		mutate {
			rename => {"host" => "hostname"}
		}
	}
}
# 数据输出部分
output {
    # beat监控信息
	if [type] == "beats_log"{
		elasticsearch {
            hosts => ["192.168.X.X:9200"]
			manage_template => false
			index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
            user => "elastic"
            password => "elastic2021"
        }
	}
    # nginx访问日志
    if[type] == "nginx-access-log" {
        elasticsearch {
            hosts => ["192.168.X.X:9200"]
            index => "nginx-access-log-%{+YYYY.MM.dd}" 
			# elasticsearch的用户名、密码
            user => "elastic"
            password => "elastic2021"
        }
    }
    # nginx异常日志
    if[type] == "nginx-error-log"{
        elasticsearch{
            hosts => ["192.168.X.X:9200"]
            index => "nginx-error-log-%{+YYYY.MM.dd}"
            user => "elastic"
            password => "elastic2021"
        }
    }
	# 应用系统日志
	if[type] == "application-log"{
		elasticsearch {
			hosts => ["192.168.X.X:9200"]   
			index => "application-log-%{+YYYY.MM.dd}"
			user => "elastic"
			password => "elastic2021"
		}
	}
}

3.启动命令

cd /data/app/elk/elk-6.8.5/logstash-6.8.5
nohup ./bin/logstash -f config/logstash.conf &

4.查看Logstash是否启动成功

ps -ef | grep logstash

二、配置应用项目的logback环境

1.在pom.xml中添加Logstash依赖

<!-- logstash 6.2 -->
<dependency>
   <groupId>net.logstash.logback</groupId>
   <artifactId>logstash-logback-encoder</artifactId>
   <version>6.2</version>
</dependency>

2.在resouces目录下添加logback-spring.xml

<?xml version="1.0" encoding="UTF-8" ?>
<configuration debug="false">
	<!-- 为logstash输出的JSON格式的Appender -->
	<appender name="logstash_dev"
			  class="net.logstash.logback.appender.LogstashTcpSocketAppender">
		<destination>192.168.X.X:21021</destination>
		<!-- 日志输出编码 -->
		<encoder
				class="net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder">
			<providers>
				<timestamp>
					<timeZone>UTC</timeZone>
				</timestamp>
				<pattern>
					<pattern>
						{
						"severity": "%level",
						"service": "${APP_NAME:-}",
						"trace": "%X{X-B3-TraceId:-}",
						"span": "%X{X-B3-SpanId:-}",
						"parent": "%X{X-B3-ParentSpanId:-}",
						"exportable": "%X{X-Span-Export:-}",
						"pid": "${PID:-}",
						"thread": "%thread",
						"class": "%logger",
						"rest": "%message"
						}
					</pattern>
				</pattern>
			</providers>
		</encoder>
	</appender>
	<!-- 开发环境 -->
    <springProfile name="develop">
        <!--设置根日志级别-->
        <root level="INFO">
            <appender-ref ref="logstash_dev"/>
        </root>
    </springProfile>
</configuration>
