环境：

一台 centos 6.7

IP地址：

192.168.88.250

软件版本：

ElasticSearch 2.1.0 Logstash 2.1.1 Kibana 4.3.1 JDK 1.8.0.77

JDK 我这里没有地址就不连接了

下载好JDK 放在路径/usr/local/java

编辑配置文件 /etc/profile

export JAVA_HOME=/usr/local/java/jdk1.8.0_77
export PATH=$JAVA_HOME/bin:$PATH

加入这两句以后然后 source /etc/profile

确认生效 java -version

[root@master ~]# java -version
java version "1.8.0_77"
Java(TM) SE Runtime Environment (build 1.8.0_77-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)

1、搭建 ElasticSearch

wget https://download.elasticsearch.org/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.1.0/elasticsearch-2.1.0.tar.gz
tar xf elasticsearch-2.1.0.tar.gz 
cd /usr/local/elasticsearch-2.1.0/bin
./plugin  -install mobz/elasticsearch-head  # web集群管理插件  安装好了以后可以在plugin文件发现多了一个head
./elasticsearch  -Des.insecure.allow.root=true  #加这个参数才可以root启动

curl -X GET 192.168.88.250:9200   #curl 测试
{
  "name" : "Reeva Payge",
  "cluster_name" : "elasticsearch",
  "version" : {
    "number" : "2.1.0",
    "build_hash" : "72cd1f1a3eee09505e036106146dc1949dc5dc87",
    "build_timestamp" : "2015-11-18T22:40:03Z",
    "build_snapshot" : false,
    "lucene_version" : "5.3.1"
  },
  "tagline" : "You Know, for Search"
}

2、搭建NGINX

wget   搭建nginx之前需要安装 pcre
tar xf nginx-1.7.8.tar.gz
cd /usr/local/nginx
vim /usr/local/nginx/conf/nginx.conf
#user  nobody;
worker_processes  1;

#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
   worker_connections  1024;
}

http {
  
upstream kibana4 {  #对Kibana做代理  
        server 127.0.0.1:5601 fail_timeout=0;
}
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';
                     
     log_format json '{"@timestamp":"$time_iso8601",'   #配置NGINX的日志格式 json
                        '"host":"$server_addr",'
                        '"clientip":"$remote_addr",'
                        '"size":$body_bytes_sent,'
                        '"responsetime":$request_time,'
                        '"upstreamtime":"$upstream_response_time",'
                        '"upstreamhost":"$upstream_addr",'
                        '"http_host":"$host",'
                        '"url":"$uri",'
                        '"xff":"$http_x_forwarded_for",'
                        '"referer":"$http_referer",'
                        '"agent":"$http_user_agent",'
                        '"status":"$status"}';
     access_log /var/log/nginx/access.log_json json;   #配置日志路径 json格式
     error_log /var/log/nginx/error.log;  

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {

        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }



    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;

    #    location / {

    #    }
    #}

  
server {
    listen               *:80;
    server_name          kibana_server;
    access_log           /var/log/nginx/kibana.srv-log-dev.log;
    error_log            /var/log/nginx/kibana.srv-log-dev.error.log;


    location / {
        root   /var/www/kibana;
        index  index.html  index.htm;
    }

    location ~ ^/kibana4/.* {
        proxy_pass           http://kibana4;
        rewrite              ^/kibana4/(.*)  /$1 break;

        auth_basic_user_file /etc/nginx/conf.d/kibana.myhost.org.htpasswd;
    }

}
}

3、搭建 Logstash

wget https://download.elastic.co/logstash/logstash/logstash-2.1.1.tar.gz
tar xf logstash-2.1.1.tar.gz 
cd /usr/local/logstash-2.1.1/bin
vim stdin.conf #编写配置文件
input{
        file {
                path => "/var/log/nginx/access.log_json"  #NGINX日志地址 json格式
               codec => "json"  json编码
        }
}
filter {
        mutate {
                split => ["upstreamtime", ","]    
        }
        mutate {
                convert => ["upstreamtime", "float"]
        }
}
output{

        elasticsearch {
                hosts => ["192.168.88.250:9200"]   #elasticsearch地址
                index => "logstash-%{type}-%{+YYYY.MM.dd}"   #索引
                document_type => "%{type}"    
                workers => 1
                flush_size => 20000        #传输数量 默认500
                idle_flush_time => 10      #传输秒数  默认1秒
                template_overwrite => true   
        }
}
 ./logstash -f stdin.conf &  #后台启动
启动成功以后 打开刚才搭建的web服务器  es就能看到数据

4、搭建Kibana

wget https://download.elastic.co/kibana/kibana/kibana-4.3.1-linux-x64.tar.gz
tar xf kibana-4.3.1-linux-x64.tar.gz
cd /usr/local/kibana-4.3.1-linux-x64/
vim ./config/kibana.yml

elasticsearch.url: "   只需要修改URL为ElasticSearch的IP地址
./kibana &  后台启动

启动成功以后 会监听 5601端口

全部搭建好了以后就可以用Kibana查看

地址 : 192.168.88.250:5601
