ELK 日志平台搭建

一.平台了解

1.1 ElasticSearch是一个基于Lucene构建的开源,分布式,RESTful搜索引擎。设计用于云计算中,能够达到实时搜索,稳定,可靠,快速,安装使用方便。支持通过HTTP使用JSON进行数据索引。

1.2 logstash是一个应用程序日志、事件的传输、处理、管理和搜索的平台。你可以用它来统一对应用程序日志进行收集管理,提供 Web 接口用于查询和统计。其实logstash是可以被别的替换,比如常见的fluented

1.3 Kibana是一个为 Logstash 和 ElasticSearch 提供的日志分析的 Web 接口。可使用它对日志进行高效的搜索、可视化、分析等各种操作。

Redis是一个高性能的内存key-value数据库,非必需安装,可以防止数据丢失.

二.架构拓扑

三 安装部署

2.1 客户端:nginx+logstash 192.168.127.141

服务端:logstash+redis+elasticSearch+kibana 192.168.127.140 #本例子将三个组件同时安装在一台服务器。

服务器端安装

JDK 安装

yum install java-1.8.0-openjdk

redis 部署

#tar –xvzf redis-3.0.4.tar.gz

#cd redis-3.0.4

#make

#make install

#cd utils

#./install_server.sh

这样redis就安装好了
#which redis-server在/usr/local/bin/redis-server

配置文件放在/etc/redis/6379.conf文件

#redis-cli

>set aa aavalue

>get aa 即可测试。
#cd

elasticsearch 部署

#tar –xvzf elasticsearch-1.7.1.tar.gz

#cp –a elasticsearch-1.7.1 /usr/local

#cd /usr/local

#ln –s elasticsearch-1.7.1 elasticsearch

#cd

这里我们可以下载一个elasticsearch的启动脚本来启动elasticsearch

git   clone  git@github.com:smail-bao/elk.git

然后把service目录挪到elasticsearch/bin目录下

然后执行/elasticsearch/bin/service/elasticsearch install

就可以把elasticsearch 就开机自动启动,且我们可以使用/etc/init.d/elasticsearch   了

部署中心logstash

#tar –xvzf logstash-1.5.4.tar.gz

#cp –a logstash-1.5.4 /usr/local

#cd /usr/local

#ln –s logstash-1.5.4 logstash

#cd /usr/local/logstash

#cd conf && vim logstash_server.conf

input {
        redis {
                host => "127.0.0.1"           
                port => 6379                  
                type => "redis-input"             
            data_type => "list"                
                key => "logstash:redis"
        }
}
output {
        stdout {}
        elasticsearch {
                host => "192.168.220.116"               
                cluster => "elasticsearch"
                codec => "json"
                protocol => "http"                   
        }
}

配置文件的意思就是,输入来自redis,使用redis的list类型存储数据,key为"logstash:redis",输出到elasticsearch,cluster的名称为elasticsearch,这里的cluster 就是elasticsearch.yml里面的cluster.name,集群的名称

kibana部署

#tar –xvzf kibana-4.1.2-linux-x64.tar.gz

#cp –a kibana-4.1.2-linux-x64 /usr/local

#cd /usr/local

#ln –s kibana-4.1.2-linux-x64 kibana

我们再下载一个kibana的脚本文件,注意这里要修改自己相应的软件安装路劲

该脚本来自:http://www.open-open.com/lib/view/open1441088477784.html

git  clone   git@github.com:smail-bao/elk.git
#创建kibana服务 vi /etc/rc.d/init.d/kibana #!/bin/bash ### BEGIN INIT INFO # Provides: kibana # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Runs kibana daemon # Description: Runs the kibana daemon as a non-root user ### END INIT INFO # Process name NAME=kibana DESC="Kibana4" PROG="/etc/init.d/kibana" # Configure location of Kibana bin KIBANA_BIN=/usr/local/kibana/bin # PID Info PID_FOLDER=/var/run/kibana/ PID_FILE=/var/run/kibana/$NAME.pid LOCK_FILE=/var/lock/subsys/$NAME PATH=/bin:/usr/bin:/sbin:/usr/sbin:$KIBANA_BIN DAEMON=$KIBANA_BIN/$NAME # Configure User to run daemon process DAEMON_USER=root # Configure logging location KIBANA_LOG=/var/log/kibana.log # Begin Script RETVAL=0 if [ `id -u` -ne 0 ]; then echo "You need root privileges to run this script" exit 1 fi # Function library . /etc/init.d/functions start() { echo -n "Starting $DESC : " pid=`pidofproc -p $PID_FILE kibana` if [ -n "$pid" ] ; then echo "Already running." exit 0 else # Start Daemon if [ ! -d "$PID_FOLDER" ] ; then mkdir $PID_FOLDER fi daemon --user=$DAEMON_USER --pidfile=$PID_FILE $DAEMON 1>"$KIBANA_LOG" 2>&1 & sleep 2 pidofproc node > $PID_FILE RETVAL=$? [[ $? -eq 0 ]] && success || failure echo [ $RETVAL = 0 ] && touch $LOCK_FILE return $RETVAL fi } reload() { echo "Reload command is not implemented for this service." return $RETVAL } stop() { echo -n "Stopping $DESC : " killproc -p $PID_FILE $DAEMON RETVAL=$? echo [ $RETVAL = 0 ] && rm -f $PID_FILE $LOCK_FILE } case "$1" in start) start ;; stop) stop ;; status) status -p $PID_FILE $DAEMON RETVAL=$? ;; restart) stop start ;; reload) reload ;; *) # Invalid Arguments, print the following message. echo "Usage: $0 {start|stop|status|restart}" >&2 exit 2 ;; esac #修改启动权限 chmod +x /etc/rc.d/init.d/kibana #启动kibana服务 service kibana start service kibana status

程序安装全部完成。

由于elasticsearch和logstash是安装在一台机器上所以elasticsearch默认配置即可。
/usr/local/elasticsearch/bin/elasticsearch –d (以deamon方式启动elasticsearch)

访问192.168.127.141:9200即可看到

配置logstash程序
# cd /usr/local/logstash下,mkdir etc logs两个文件夹,etc用于存放配置文件,logs用于存放日志文件
在该etc目录下建立一个central.conf配置文件:

# cat /usr/local/logstash/etc/central.conf

input {

redis {

host => "127.0.0.1"

port => 6379

type => "redis_input"

data_type => "list"

key => "logstash:redis"

}

}

output {

stdout {}

elasticsearch {

cluster => "elasticsearch"

codec => "json"

protocol => "http"

}

}

该文件说明是以redis为输入,输出到elasticsearch程序,格式为json协议为http.

启动logstash程序如下:

#/usr/local/logstash/bin/logstash -f /usr/local/logstash/etc/central.conf -l /usr/local/logstash/logs/stdout.log

Sending logstash logs to /usr/local/logstash/logs/stdout.log.

Kibana程序现在是4版本了,自带web,端口为5601:

#cd /usr/local/kibana/bin/

#./kibana程序即可。

[root@localhost bin]# ./kibana

{"name":"Kibana","hostname":"localhost.localdomain","pid":1645,"level":30,"msg":"Found kibana index","time":"2016-01-28T05:00:17.462Z","v":0}

{"name":"Kibana","hostname":"localhost.localdomain","pid":1645,"level":30,"msg":"Listening on 0.0.0.0:5601","time":"2016-01-28T05:00:18.205Z","v":0}

现在可以打开 kibana的页面了。

192.168.127.140:5601

四 客户端安装

现在要在客户端(192.168.127.141)收集日志

#tar –xvzf logstash-1.5.4.tar.gz

#cp –a logstash-1.5.4 /usr/local

#cd /usr/local

#ln –s logstash-1.5.4 logstash

#cd /usr/local/logstash目录
同样需要#mkdir etc logs存放配置文件和日志文件。
# cat etc/logstash_agent.conf

input {

file {

type => "nginx_access"

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

}

}

output {

redis {

host => "192.168.127.140"

data_type => "list"

key => "logstash:redis"

}

}

启动该logstash程序即可。
#/usr/local/logstash/bin/logstash –f /usr/local/logstash/etc/logstash_agent.conf

最后打开kibana查看采集到的nginx访问日志
