es1镜像

两个容器 171.111.0.11

172.111.0.12

npm可以不装

l logstash

k 也有

logstash镜像

拉取logstash和kibana的v6.7.2版本镜像

docker pull logstash:6.7.2
docker pull kibana:6.7.2

logstash镜像编排

cd /opt/logstash
vim logstash.yml
# 编写yml文件
http.host: "0.0.0.0"
xpack.monitoring.elasticsearch.url: [ "http://es1:9200","http://es2:9201" ]
​
vim logstash.conf
# 编写 conf 文件，定义输入输出，指定输入之一为宿主机Apache的日志文件
input {
  tcp {
    mode => "server"
    host => "0.0.0.0"
    port => 5044
    codec => "json"
  }
  file {
    path => "/opt/logs/*_log"
    start_position => "beginning"
  }
}
output {
  elasticsearch {
    hosts => [ "http://es1:9200","http://es2:9201" ]
    index => "elk-%{+YYYY.MM.dd}"
  }
}

为了方便，把logstash镜像的权限设置为root，否则宿主机共享过去的Apache日志文件logstash都无权限访问

vim Dockerfile
​
FROM logstash:6.7.2
USER root
COPY logstash.yml ./config/logstash.yml
COPY logstash.conf ./pipeline/logstash.conf

docker build -t logstash:elk . 
docker run -itd --name logstash -v /etc/httpd/logs/:/opt/logs/ --net mynetwork1 --ip 172.111.0.30 -p 5044:5044 -p 9600:9600 logstash:elk
docker exec -it logstash bash
cd /opt/logs/
doc  

访问几次宿主机的Apache服务，并查看Apache的日志文件是否共享到容器内

kibana镜像编排

cd /opt/kibana
vim kibana.yml
server.name: kibana
server.host: "0"
elasticsearch.hosts: [ "http://172.111.0.11:9200","http://172.111.0.12:9201" ]
​
vim Dockerfile

FROM kibana:6.7.2
COPY kibana.yml ./config/kibana.yml
USER root
RUN chown kibana.kibana ./config/kibana.yml
USER kibana

docker build -t kibana:elk . 
docker run -itd --name kibana --net mynetwork --ip 172.111.0.40 -p 5601:5601 kibana:elk
docker exec -it kibana bash

访问kibana的web页面，查看日志数据并建立对应索引
