Linux服务端配置
创建文件夹，用来存放elk相关的数据
$ mkdir /data/elk
1
创建logstash配置文件：logstash-springboot.conf
$ touch /data/elk/logstash/logstash-springboot.conf
1
编辑logstash-springboot.conf文件，写入以下内容
input {
tcp {
mode => "server"
host => "0.0.0.0"
port => 4560
codec => json_lines
}
}
output {
elasticsearch {
hosts => "es:9200"
index => "springboot-logstash-%{+YYYY.MM.dd}"
}
创建docker-compose.yml文件
$ touch /data/elk/docker-compose.yml
1
编写docker-compose.yml文件，写入以下内容
version: '3'
services:
elasticsearch:
image: elasticsearch:7.6.2
container_name: elasticsearch
privileged: true
user: root
environment:
- "cluster.name=elasticsearch" #设置集群名称为elasticsearch
- "discovery.type=single-node" #以单一节点模式启动
- "ES_JAVA_OPTS=-Xms512m -Xmx512m" #设置使用jvm内存大小
volumes:
- /data/elk/elasticsearch/plugins:/usr/share/elasticsearch/plugins #插件文件挂载
- /data/elk/elasticsearch/data:/usr/share/elasticsearch/data #数据文件挂载
ports:
- 9200:9200
- 9300:9300
logstash:
image: logstash:7.6.2
container_name: logstash
privileged: true
environment:
- TZ=Asia/Shanghai
volumes:
- /data/elk/logstash/logstash-springboot.conf:/usr/share/logstash/pipeline/logstash.conf #挂载logstash的配置文件
depends_on:
- elasticsearch #logstash在elasticsearch启动之后再启动
links:
- elasticsearch:es #可以用es这个域名访问elasticsearch服务
ports:
- 4560:4560
kibana:
image: kibana:7.6.2
container_name: kibana
privileged: true
links:
- elasticsearch:es #可以用es这个域名访问elasticsearch服务
depends_on:
- elasticsearch #kibana在elasticsearch启动之后再启动
environment:
- "elasticsearch.hosts=http://es:9200" #设置访问elasticsearch的地址
ports:
- 5601:5601
在docker-compose.yml所在目录执行启动命令
$ docker-compose up -d
1
如果Elasticsearch启动报错，/usr/share/elasticsearch/data下的文件无权限，请给宿主机挂载的/data/elk/elasticsearch/data赋予权限：
$ chmod 777 /data/elk/elasticsearch/data
1
遇到错误时先关闭并删除容器
$ docker-compose down
1
在logstash中安装json_lines插件
# 进入logstash容器
docker exec -it logstash /bin/bash
# 进入bin目录
cd /bin/
# 安装插件
logstash-plugin install logstash-codec-json_lines
# 退出容器
exit
# 重启logstash服务
docker restart logstash
客户端配置
注意：本例应用服务是基于springboot开发的项目。
在pom.xml中引入依赖
<!--集成logstash-->
<dependency>
<groupId>net.logstash.logback</groupId>
<artifactId>logstash-logback-encoder</artifactId>
<version>5.3</version>
</dependency>
在resources文件夹下增加 logback-spring.xml文件，并写入以下内容
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration>
<configuration>
<include resource="org/springframework/boot/logging/logback/defaults.xml"/>
<include resource="org/springframework/boot/logging/logback/console-appender.xml"/>
<!--应用名称-->
<property name="APP_NAME" value="springboot-logback-elk-demo"/>
<!--日志文件保存路径-->
<property name="LOG_FILE_PATH" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}}/logs}"/>
<contextName>${APP_NAME}</contextName>
<!--每天记录日志到文件appender-->
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>${LOG_FILE_PATH}/${APP_NAME}-%d{yyyy-MM-dd}.log</fileNamePattern>
<maxHistory>30</maxHistory>
</rollingPolicy>
<encoder>
<pattern>${FILE_LOG_PATTERN}</pattern>
</encoder>
</appender>
<!--输出到logstash的appender-->
<appender name="LOGSTASH" class="net.logstash.logback.appender.LogstashTcpSocketAppender">
<!--可以访问的logstash日志收集端口-->
<destination>192.168.0.150:4560</destination>
<encoder charset="UTF-8" class="net.logstash.logback.encoder.LogstashEncoder"/>
</appender>
<root level="INFO">
<appender-ref ref="CONSOLE"/>
<appender-ref ref="FILE"/>
<appender-ref ref="LOGSTASH"/>
</root>
</configuration>
192.168.0.150:4560为我本机logstash的ip和端口，请自行设置。
重新启动项目后，项目输出的日志都会被收集到elk中。
