七、安装部署elasticsearch集群

八、安装kibana


一、ELK说明

ELK Stack 是 Elasticsearch、Logstash、Kibana 三个开源软件的组合。在实时数据检索和分析场合,三者通常是配合共用,而且又都先后归于 Elastic.co 公司名下,故有此简称。

ELK Stack 在最近两年迅速崛起,成为机器数据分析,或者说实时日志处理领域,开源界的第一选择。和传统的日志处理方案相比,ELK Stack 具有如下几个优点:

处理方式灵活。Elasticsearch 是实时全文索引,不需要像 storm 那样预先编程才能使用;

配置简易上手。Elasticsearch 全部采用 JSON 接口,Logstash 是 Ruby DSL 设计,都是目前业界最通用的配置语法设计;

检索性能高效。虽然每次查询都是实时计算,但是优秀的设计和实现基本可以达到全天数据查询的秒级响应;

集群线性扩展。不管是 Elasticsearch 集群还是 Logstash 集群都是可以线性扩展的;

前端操作炫丽。Kibana 界面上,只需要点击鼠标,就可以完成搜索、聚合功能,生成炫丽的仪表板。

    }
}

4.6.启动nginx

/app/local/nginx/sbin/nginx -c /app/local/nginx/conf/nginx.conf

4.7.部署java环境

下载oracle jdk 

http://www.oracle.com/technetwork/java/javase/downloads/index-jsp-138363.html


4.8.安装jdk

tar -xf jdk-8u91-linux-x64.tar.gz -C /usr/local/   
vim /etc/profile
export JAVA_HOME=/usr/local/jdk1.8.0_91
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar


4.9.安装logstsh

下载:https://www.elastic.co/

#yum install logstash-2.3.2-1.noarch.rpm

4.10.配置logstash

vim /etc/logstash/conf.d/logstash_cli.conf 
input {
     file {
        path => ["/app/local/nginx/logs/access.log"]
        type => "nginx_log"
        start_position => "beginning"
     }
}
output {
    stdout {
codec => rubydebug
    }
}


检查语法:

/opt/logstash/bin/logstash -f ./logstash_cli.conf --configtest
Configuration OK

启动查看收集nginx状况

# /opt/logstash/bin/logstash -f ./logstash_cli.conf

          "host" => "qmcent7.com",
          "type" => "nginx_log"
}
........................

修改配置文件,将数据输出到redis:

 vim /etc/logstash/conf.d/logstash_cli.conf 
input {
     file {
        path => ["/app/local/nginx/logs/access.log"]
        type => "nginx_log"
        start_position => "beginning"
     }
}
output {

         host => "192.168.1.89"
         key => 'logstash-redis'
         data_type => 'list'
    }
}

检查语法:

/opt/logstash/bin/logstash -f ./logstash_cli.conf --configtest
Configuration OK

启动服务:

/etc/init.d/logstash start

查看进程:

        type => "redis-input"
   }
}
output {
    stdout {
codec => rubydebug
    }
}

检查语法:

/opt/logstash/bin/logstash -f ./logstash_server.conf --configtest
Configuration OK

检查收集数据:

# /opt/logstash/bin/logstash -f ./logstash_server.conf 
Settings: Default pipeline workers: 4
Pipeline main started
{
       "message" => "192.168.1.105 - - [11/May/2016:22:00:53 +0800] \"GET / HTTP/1.1\" 200 612 \"-\" \"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.75 Safari/537.36\" - 369 1462975253.311 1 0.000",

          "path" => "/app/local/nginx/logs/access.log",
          "host" => "qmcent7.com",
          "type" => "nginx_log"
.....

修改logstash配置文件:

将收集的数据输出到ES集群中

input {
    redis {
        port => "6379"
        host => "192.168.1.89"
        data_type => "list"
        key => "logstash-redis"
        type => "redis-input"
   }
}
output {
    elasticsearch {
        hosts => "192.168.1.91"
        index => "logstash-%{+YYYY.MM.dd}"
   }
}


启动服务:

/etc/init.d/logstash start


七、安装部署elasticsearch集群

192.168.1.88(elasticsearch)
192.168.1.91(elasticsearch)
192.168.1.92(elasticsearch)


部署java环境,全部一致:

tar -xf jdk-8u91-linux-x64.tar.gz -C /usr/local/

   
vim /etc/profile
export JAVA_HOME=/usr/local/jdk1.8.0_91
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar


安装ES、全部一致:

yum install elasticsearch-2.3.2.rpm

192.168.1.88(elasticsearch)

修改ES配置文件:

vim  /etc/elasticsearch/elasticsearch.yml
cluster.name: qm.ela.com 
node.name: n1.qm.com
path.logs: /data/log/
network.host: 192.168.1.88
http.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.1.91","192.168.1.92"]

[88]启动服务:

/etc/init.d/elasticsearch start

192.168.1.91(elasticsearch)

修改ES配置文件:

vim  /etc/elasticsearch/elasticsearch.yml
cluster.name: qm.ela.com 
node.name: n2.qm.com
path.logs: /data/log
network.host: 192.168.1.91
http.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.1.88","192.168.1.92"]

[91]启动服务:

/etc/init.d/elasticsearch start


192.168.1.92(elasticsearch)

vim  /etc/elasticsearch/elasticsearch.yml
cluster.name: qm.ela.com 
node.name: n3.qm.com
path.logs: /data/log
network.host: 192.168.1.92 
http.port: 9200
discovery.zen.ping.unicast.hosts: ["192.168.1.88","192.168.1.91"]


[92]启动服务:

/etc/init.d/elasticsearch start

启动两个端口

9200:集群之间事务通信

9300:集群选举等


信息查看

1.查看健康信息:

# curl -XGET 'http://192.168.1.88:9200/_cluster/health?pretty' 
{
  "cluster_name" : "qm.ela.com",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 3,
  "number_of_data_nodes" : 3,
  "active_primary_shards" : 14,

  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 100.0
}

2.查看节点数:
