Kibana+Logstash+Elasticsearch日志查询系统，kibanalogstash_PHP教程

Kibana+Logstash+Elasticsearch 日志查询系统，kibanalogstash

　　搭建该平台的目的就是为了运维、研发很方便的进行日志的查询。Kibana一个免费的web壳；Logstash集成各种收集日志插件，还是一个比较优秀的正则切割日志工具；Elasticsearch一个开源的搜索引擎框架（支持群集架构方式）。

3.1.2 Redis启动

[logstash@Logstash_2 redis]# redis-server /data/redis/etc/redis.conf &

3.2 Elasticsearch 配置及启动

3.2.1 Elasticsearch启动

[logstash@Logstash_2 redis]# /data/elasticsearch/elasticsearch-0.18.7/bin/elasticsearch –p ../esearch.pid &

3.2.2 Elasticsearch 群集配置

curl 127.0.0.1:9200/_cluster/nodes/192.168.50.62

3.3 Logstash配置及启动

3.3.1 Logstash配置文件

input {

redis {

host => "192.168.50.98"

data_type =>"list"

key => "logstash:redis"

type => "redis-input"

}

}

filter {

grok {

type => "linux-syslog"

pattern => "%{SYSLOGLINE}"

}

grok {

type => "nginx-access"

pattern => "%{NGINXACCESSLOG}"

}

}

output {

elasticsearch {

host =>"192.168.50.62"

}

}

}

file {

type => "nginx-access"

path => "/usr/local/nginx/logs/access.log"

3.3.4 kibana配置

首先在nginx添加站点配置

server {

listen 80;

server_name logstash.test.com;

index index.php;

root /usr/local/nginx/html;

#charset koi8-r;

#access_log logs/host.access.log main;

location ~ .*\.(php|php5)$

{

#fastcgi_pass unix:/tmp/php-cgi.sock;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

include fastcgi.conf;

}

}

4 性能调优

4.1 Elasticsearch调优

4.1.1 JVM调优

编辑Elasticsearch.in.sh文件

ES_CLASSPATH=$ES_CLASSPATH:$ES_HOME/lib/*:$ES_HOME/lib/sigar/*

if [ "x$ES_MIN_MEM" = "x" ]; then

ES_MIN_MEM=4g

fi

if [ "x$ES_MAX_MEM" = "x" ]; then

ES_MAX_MEM=4g

fi

4.1.2 Elasticsearch索引压缩

vim index_elastic.sh

#!/bin/bash

#comperssion the data for elasticsearch now

date=` date +%Y.%m.%d `

# compression the new index;

/usr/bin/curl -XPUT http://localhost:9200/logstash-$date/nginx-access/_mapping -d '{"nginx-access" : {"_source" : { "compress" : true }}}'

echo ""

/usr/bin/curl -XPUT http://localhost:9200/logstash-$date/nginx-error/_mapping -d '{"nginx-error" : {"_source" : { "compress" : true }}}'

echo ""

/usr/bin/curl -XPUT http://localhost:9200/logstash-$date/linux-syslog/_mapping -d '{"linux-syslog" : {"_source" : { "compress" : true }}}'

echo ""

保存该脚本并执行

sh index_elastic.sh
