ElasticSearch6.0-head插件安装(界面查看es索引)

#网址:http://www.cnblogs.com/Onlywjy/p/Elasticsearch.html
#包D:\share\src\elk\elk6.0\elasticsearch-head插件
1.安装node
    tar -C /opt/ -zxvf node-v4.4.7-linux-x64.tar.gz

    vim /etc/profile.d/node.sh   #配置node环境变量
        export NODE_HOME=/opt/node-v4.4.7-linux-x64
        export PATH=$PATH:$NODE_HOME/bin
        export NODE_PATH=$NODE_HOME/lib/node_modules
    source /etc/profile.d/node.sh

2.安装grunt
    unzip elasticsearch-head-master.zip
    cd elasticsearch-head-master
    npm install -g grunt-cli  //执行后会生成node_modules文件夹

    grunt -version #检查是否安装成功

    修改head插件源码
        修改服务器监听地址:Gruntfile.js  #93行，默认端口号库9100
    修改连接地址：_site/app.js   #4354行，修改es连接地址,注意这个地址只能是外网地址,相对于访问head的机子

3.运行head
    在elasticsearch-head-master目录下
    npm install   #(安装下载下来的包，如果出错再执行一遍)
    grunt server &  #后台启动、netstat -lnp | grep 9100
4.访问http://xxx:9100

5.head使用(添加索引，往索引里写数据，修改索引数据，删除索引)

 ElasticSearch6.0索引清理

curl -XGET 'http://192.168.55.219:9200/_cat/indices/?v'  #查询索引
curl -XDELETE 'http://127.0.0.1:9200/logstash-2016-07-*'  #api删除索引

脚本加api删除（推荐）
    vim /opt/sh/es-index-clear.sh

    #/bin/bash

    #指定日期(7天前)
    DATA=`date -d "1 week ago" +%Y.%m.%d`

    #当前日期
    time=`date`

    #删除7天前的日志
    curl -XDELETE http://127.0.0.1:9200/*-${DATA}

    if [ $? -eq 0 ];then
      echo $time"-->del $DATA log success.." >> /tmp/es-index-clear.log
    else
      echo $time"-->del $DATA log fail.." >> /tmp/es-index-clear.log
    fi
添加到任务计划
    crontab -e
    10 1 * * * sh /tmp/es-index-clear.sh > /dev/null 2>&1

 

 elasticSearch常用命令

原网址:https://zhaoyanblog.com/archives/732.html
curl 'localhost:9200/_cluster/health?pretty' 健康检查
curl 'localhost:9200/_cluster/state?pretty'    集群详细信息

curl -XPUT http://localhost:9200/user #添加索引
curl -H "Content-Type:application/json" -XPUT http://192.168.56.10:9200/user/ceshi/1/ -d '{"id":2,"name":"ceshi2","age":222}' #索引里写文档，user是索引,ceshi是索引类型，1是索引id
curl -XGET http://localhost:9200/user #查看索引内容

curl -XDELETE  http://localhost:9200/user #删除索引，支持通配符

 安装kibana和使用

kibana安装

rpm -ivh kibana-6.0.0-x86_64.rpm
vim /etc/kibana/kibana.yml
    server.port: 5601
    server.host: 0.0.0.0
    elasticsearch.url: "http://192.168.56.10:9200" #连接到主
    logging.dest: /var/log/kibana/kibana.log
/etc/init.d/kibana start   #默认端口5601

 logstash安装和使用例子

logstash安装

ln -sv /opt/apps/java/bin/java /usr/bin/  
rpm -ivh logstash-6.0.0.rpm
目录结构:
    /usr/share/logstash/bin 
    /var/lib/logstash
    /var/log/logstash
    注意这几个目录的用户和组必须是logstash
    如果用root用户启动logstash后  需要把上面几个目录的用户和组修改下(chown -R logstash.logstash xxxx)
#生成启动脚本
    1、要跟startup.options文件的绝对路径，如果是rpm安装的在/etc/logstash/startup.options，如果是二进制包解压安装的则在解压目录下的config目录下面。

    2、必须要跟启动类型，比如CentOS6是sysv，CentOS7是systemd。(备注:sysv在centos7里也能用)

    3、执行脚本生成启动文件
         /usr/share/logstash/bin/system-install /etc/logstash/startup.options sysv
    4、修改/etc/init.d/logstash
    75行 >> /var/log/logstash/logstash-plain.log 2>> /var/log/logstash/logstash-plain.log
#更改日志目录权限
    chown -R logstash.logstash /var/log/logstash

#配置Logstash to elasticsearch文件
    vim /etc/logstash/conf.d/log_to_es.conf
    =========================================
    input{
        file{
            path => "/var/log/messages"
            start_position => "beginning"
            type => "message"
        }
    }
    output{
        if [type] == "message" {
            elasticsearch{
                  hosts => "192.168.56.10:9200"
                  #hosts => ["10.10.1.90:9200","10.10.1.60:9200"] #多node data 就里配置的是node data,不要配置node master

                  index => "message-%{+YYYY-MM}"
                  #index => "message-%{+YYYY-MM-dd}"
            }
          }
    }
    ========================================

#更改/var/log/messages权限
chmod 644 /var/log/messages

#检查配置文件有没有错误
    /usr/share/logstash/bin/logstash --path.settings /etc/logstash/ -f /etc/logstash/conf.d/log_to_es.conf --config.test_and_exit
#启动
/etc/init.d/logstash start 
#检查启动是否成功
netstat -lnp | grep 9600 或查看日志 tail -f /var/log/logstash/logstash-plain.log
