使用docker-compose部署elk
准备docker-compose.yml文件
[root@192 mall-elk]# pwd
/root/docker/mall-elk
[root@192 mall-elk]# vim docker-compose.yml
内容如下:
version: '3'
services:
elasticsearch:
image: elasticsearch:7.10.1
container_name: elasticsearch
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:
- /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins #插件文件挂载
- /mydata/elasticsearch/data:/usr/share/elasticsearch/data #数据文件挂载
ports:
- 9200:9200
kibana:
image: kibana:7.10.1
container_name: kibana
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
logstash:
image: logstash:7.10.1
container_name: logstash
volumes:
- /mydata/logstash/logstash-springboot.conf:/usr/share/logstash/pipeline/logstash.conf #挂载logstash的配置文件
depends_on:
- elasticsearch #kibana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
准备logstash的配置文件 logstash-springboot.conf
放到 /mydata/logstash/ 目录下,没有这个额目录旧新建下
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}"
}
}
执行docker-compose命令运行elk,需要在docker-compose.yml文件目录下执行,默认找的就是这个文件名
[root@192 mall-elk]# pwd
/root/docker/mall-elk
[root@192 mall-elk]# docker-compose up -d
Creating elasticsearch ... done
Creating logstash ... error
Creating kibana ...
## docker ps 看下,都运行起来了
[root@192 mall-elk]# docker ps

测试es是否正常
[root@192 mall-elk]# curl localhost:9200
curl: (7) Failed connect to localhost:9200; 拒绝连接
# 发现运行不正常,查看下es的日志
[root@192 mall-elk]# docker logs elasticsearch

发现上面错误,于是百度了一下,说是es挂载的本地目录权限不够。
[root@192 mall-elk]# cd /mydata/elasticsearch/
[root@192 elasticsearch]# ll
总用量 0
drwxr-xr-x. 2 root root 6 9月 22 22:36 data
drwxr-xr-x. 2 root root 6 9月 22 22:36 plugins
# 修改下权限
[root@192 elasticsearch]# chmod 777 -R *
[root@192 elasticsearch]# ll
总用量 0
drwxrwxrwx. 2 root root 6 9月 22 22:36 data
drwxrwxrwx. 2 root root 6 9月 22 22:36 plugins
# 然后重启es容器
[root@192 elasticsearch]# docker restart elasticsearch
elasticsearch
# 再次测试就正常了
[root@192 elasticsearch]# curl localhost:9200

springBoot整合logstash
引入pom(楼主springBoot的版本是2.6.5)
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
<!--集成logstash-->
<dependency>
<groupId>net.logstash.logback</groupId>
<artifactId>logstash-logback-encoder</artifactId>
<version>5.3</version>
</dependency>
logback.xml文件内容
<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
<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="mall-admin"/>
<!--日志文件保存路径-->
<property name="LOG_FILE_PATH" value="/var/mall/logs"/>
<property name="FILE_LOG_PATTERN" value="%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n"/>
<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。这里的ip换上你自己的 -->
<destination>192.168.245.133:4560</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>
然后启动springBoot服务
kibana配置
登录kibana。http://192.168.245.133:5601/app/dev_tools#/console
1999224-20220922225023564-612367928.png点击左侧的Dev Tools
查询索引,可以看到,我们 springboot-logstash-2022.09.22 这个索引。这个 springboot-logstash前缀的索引就是我们利用logstash收集日志的索引
GET /_cat/indices?v
1999224-20220922225023564-612367928.png
现在配置kibana查询

创建好之后,重新点击左侧的Discover,就可以看到日志了
