Elasticstack官网:https://www.elastic.co
本文档仅限搭建过程参考,使用相关的文档,不在本文档讨论范围之内。
一切依据的核心即是Elasticstack官网。

查看支持的操作系统:
Elasticstack各版本软件支持的系统等:https://www.elastic.co/support/matrix#show_os
必备软件:
Elasticsearch:elasticsearch-5.3.0.tar.gz
Logstash:logstash-5.3.0.tar.gz
Kibana:kibana-5.3.0-linux-x86_64.tar.gz
Beats:filebeat-5.3.0-linux-x86_64.tar.gz
X-pack:x-pack-5.3.0.zip
jdk1.8:jdk-8u121-linux-i586.tar
搭建流程:
Elasticsearch:
https://www.elastic.co/guide/en/elasticsearch/reference/current/index.html
修改时区(如必要):
cp -f /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
安装JDK1.8,先安装yum install -y glibc.i686
root权限下
sysctl -w vm.max_map_count=262144
/etc/security/limits.conf 增加 
* soft nproc 2048 (第一列为Linux账户名)
* hard nproc 4096(第一列为Linux账户)
* soft nofile 65536
* hard nofile 131072
/etc/security/limits.d/90-nproc.conf 修改
* soft nproc 2048
sudo sysctl -p
生产环境需要的配置
Elasticsearch通过name判断所属的集群
  ● path.data and path.logs
      ○ 不要和安装目录放一起,防止升级的时候数据丢失
      ○ 可以配置多个目录
  ● cluster.name
      ○ 各节点通过cluster.name加入集群
  ● node.name
      ○ 保证重启机器名称不变
      ○ 可以设置成机器名例如node.name:${HOSTNAME}
  ● bootstrap.memory_lock
      ○ bootstrap.memory_lock: true(遇到问题,见博客园博客)
      ○ /etc/sysctl.conf 增加vm.swappiness=0
  ● network.host
      ○ 一旦配置标志进入生产环境
  ● discovery.zen.ping.unicast.hosts
      ○ 自动入集群
  ● discovery.zen.minimum_master_nodes
      ○ 避免脑裂
生产环境需要设置bootstrap.memory_lock: true
节点如下配置,承担的角色为负载均衡
node.master: false
node.data: false
node.ingest: false
配置文件elasticsearch.yml参考:
cluster.name: rokid-test
node.name: node-41
node.master: true
node.data: true 
path.data: /home/zhangzhenghai/elk/data/elasticsearch/data
path.logs: /home/zhangzhenghai/elk/data/elasticsearch/logs
bootstrap.memory_lock: true 
bootstrap.system_call_filter: false 
network.host: test41
http.port: 9200
discovery.zen.ping.unicast.hosts:
    - test41
    - test42
    - test43
discovery.zen.minimum_master_nodes: 2 
action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*
启动方式:bin/elasticsearch -d -p pid 
停止方式:kill `cat pid`
重启方式:kill `cat pid`
    bin/elasticsearch -d -p pid 
Logstash:
参考https://www.elastic.co/guide/en/logstash/current/index.html
grok正则表达式参考:https://grokdebug.herokuapp.com/
配置文件:
input {
    beats {
        port => "5043"
    }
}
filter {
    grok {
        match => {
            "message" => "%{HOSTNAME:hostabc} %{DAY:zhouji} %{WORD:month} %{MONTHDAY:jihao} %{TIME:shijian} %{TZ:biaozhun} %{YEAR:nian} %{TIMESTAMP_ISO8601:shijianquan} \[%{WORD:zhonglei}\] %{WORD:caozuo} %{NOTSPACE:info}"
        }
    }
}
output {
    file {
        codec => line {format => "%{message}"}
        path => "/home/zhangzhenghai/elk/data/logstash/%{hostabc}.log"
    }
    elasticsearch {
        hosts => ["test41:9200","test42:9200","test43:9200"]
        index => "%{hostabc}"
        document_type => "%{hostabc}"
        flush_size => 100
        idle_flush_time => 10
        user => "elastic"
        password => "baoshan"
    }
}
上面的正则表达式对应的原始日志参考:
test-41.dev.rokid-inc.com Tue Apr 25 14:54:36 CST 2017 2017-04-16 23:37:44,282 [DEBUG] add service:com.rokid.open.nlp.facade.NLPService
启动方式(自动加载配置文件,修改配置文件不用重启Logstash):
bin/logstash -f config/firtst.conf --config.reload.automatic
Kibana:
配置文件参考:
server.port: 5601
server.host: "test43" 
elasticsearch.url: "http://test43:9200"
elasticsearch.preserveHost: true
kibana.index: ".kibana"
kibana.defaultAppId: "discover"
elasticsearch.username: "elastic"
elasticsearch.password: "xxx"
启动方式:
bin/kibana
X-Pack
bin/elasticsearch-plugin install x-pack 或者线下安装方式
bin/elasticsearch-plugin install file:///path/to/file/x-pack-5.3.1.zip
bin/kibana-plugin install file:///path/to/file/x-pack-5.3.1.zip
查看是否安装成功:
bin/kibana-plugin list
bin/elasticsearch-plugin list
(如是elastic集群,需要将所有节点安装x-pack后重启,默认用户名密码elastic/changeme才生效)
elasticsearch.yml配置如下信息
action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*
卸载x-pack
bin/elasticsearch-plugin remove x-pack
Beats(可直接写入Elasticseatch):
filebeat-5.3.0-linux-x86_64.tar.gz
配置文件参考:
filebeat.prospectors:
- input_type: log
  paths:
    - /home/zhangzhenghai/elk/data/filebeat/testdate.log
  document_type: typetest42
output.elasticsearch:
  hosts: ["test41:9200","test42:9200","test43:9200"] 
  index: "indextest42"
  username: "elastic"
  password: "xxx"
output.logstash:
  hosts: ["test39:5043"]
启动方式:
./filebeat -e -c filebeat.yml -d "publish"

可能短期内将会部署到线上,随着部署的进行,逐步更新完善本文档。
(发现每当需要文档的时候,经常嫌弃写得少;当需要自己写文档的时候,总感觉没得写?OMG)
