安装elk

# 安装 elk

本文讲述 elk(elastic、logstash,kibana)的安装步骤。logstash 负责从众多数据源(mysql、kafka 等)收集数据, 然后存储到 elastic, 最后通过 kibana 将数据可视化到界面上。elk 常用于日志收集和展示等。

# 1. 约定

操作系统：Ubuntu 16.04.3 LTS

# 2. 准备资源

jdk-8u144-linux-x64.tar.gz
elasticsearch-6.1.1.tar.gz
logstash-6.1.1.tar.gz
kibana-6.1.1-linux-x86_64.tar.gz
mysql-connector-java-5.1.41.jar

# 3. 安装

# 3.1 安装前准备操作

注意

所有安装操作都在 docker 内执行

  • 创建容器环境 docker run -itd --privileged --name elk-ubuntu -p 9100:9100 -p 9200:9200 -p 9300:9300 -p 5601:5601 ubuntu:16.04
    docker cp /data/programInstaller/elasticsearch-6.1.1.tar.gz 28:/root/
    docker cp /data/programInstaller/jdk-8u144-linux-x64.tar.gz 28:/root/
    docker cp /data/programInstaller/kibana-6.1.1-linux-x86_64.tar.gz 28:/root/
    docker cp /data/programInstaller/logstash-6.1.1.tar.gz 28:/root/
    docker cp /data/programInstaller/mysql-connector-java/5.1.41/mysql-connector-java-5.1.41.jar 28:/root/
    docker exec -it 28 bash
    apt-get update
    apt-get install vim curl net-tools -y

  • 优化配置 vi /etc/security/limits.conf

# 3.2 安装 elasticsearch

/usr/local/elasticsearch-6.1.1/bin/elasticsearch-plugin install x-pack
/usr/local/elasticsearch-6.1.1/bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.1.1/elasticsearch-analysis-ik-6.1.1.zip
vi /usr/local/elasticsearch-6.1.1/config/elasticsearch.yml

network.host: 0.0.0.0
cluster.name: my-elastic-cluster1
node.name: elastic-node-1 #如果禁用安全组件，那么就没有了用户管理功能;如果要集成 logstash，那么暂时先做如下配置才能对接成功，否则可能需要做 ssl 相关配置才行 #如果没有安装 x-pack，则不需要如下配置

/usr/local/elasticsearch-6.1.1/bin/elasticsearch --verbose -d

设置 elastic，kibana,logstash_system 的密码[约定都设置为 123456].用户名分别为 elastic,kibana,logstash_system #如果没有安装 x-pack，则不需要如下设置密码操作
/usr/local/elasticsearch-6.1.1/bin/x-pack/setup-passwords interactive

# 3.3 安装 logstash

/usr/local/logstash-6.1.1/bin/logstash-plugin install x-pack

注意

需要确保源数据库的表中含有 update_time 字段

jdbc_page_size => "50000"

statement_filepath => "/usr/local/logstash-6.1.1/jdbc.sql"
use_column_value => "true"
