ELKstack是Elasticsearch、Logstash、Kibana三个开源软件的组合。目前都在Elastic.co公司名下。
ELK是一套常用的开源日志监控和分析系统,包括一个分布式索引与搜索服务Elasticsearch,
一个管理日志和事件的工具logstash,和一个数据可视化服务Kibana
logstash_1.5.3 负责日志的收集,处理和储存
elasticsearch-1.7.2 负责日志检索和分析
kibana-4.1.2-linux-x64.tar.gz 负责日志的可视化
redis-2.4.14 DB以及日志传输的通道来处理
用一张图来表示他们之间的关系
此文以两个服务器为例来部署
服务器A:192.168.0.1 java elasticsearch redis kibana logstash(agent indexer)
服务器B:192.168.0.2 java logstash(agent)
首先安装服务器A相关软件
一、安装基础软件
yum -y install curl wget lrzsz axel
二、安装配置redis服务
1、安装tcl8.6.1
a) tar -xf tcl8.6.1-src.tar.gz --strip-components=1 b) cd tcl8.6.1/unix c) ./configure --prefix=/usr/local d) makee) make test f) make install g) make install-private-headers h) ln -v -sf tclsh8.6 /usr/bin/tclsh i) chmod -v 755 /usr/lib/libtcl8.6.so(可选,并且如报找不到文件,没关系)
2、安装redis-3.0.2
wget http://download.redis.io/releases/redis-3.0.2.tar.gz
tar xzf redis-3.0.2.tar.gz /usr/local/redis
cd redis-3.0.2
make MALLOC=libc
make test
make install
2、配置redis
a) mkdir /etc/redis
b) mkdir /var/redis
c) cp utils/redis_init_script /etc/init.d/redis
d) vim /etc/init.d/redis
头部添加:
#chkconfig: 345 60 60
#!/bin/bash
e) mkdir /var/redis/6379
f) cp redis.conf /etc/redis/6379.conf
g) vim /etc/redis/6379.conf
#设置daemonize为yes
#设置pidfile为/var/run/redis_6379.pid
#设置loglevel
#设置logfile为/var/log/redis_6379.log
#设置dir为/var/redis/6379
h) sysctl vm.overcommit_memory=1
i) chkconfig --add redis

到此服务器A的相关软件全部安装完成;
现在安装日志采集端的程序(服务器B),可以有多个
clientB安装配置logstash(agent)
1、安装java环境
yum -y list java*
yum -y install openjdk-7-jdk
1、下载logstash
wget https://download.elastic.co/logstash/logstash/packages/centos/logstash-1.5.4-1.noarch.rpm

5、启动服务
/etc/init.d/logstash startlogstash started.
6、使用jps -mlv或ps -ef来查看下进程
ps -ef|grep logst
7、设置开机启动
update-rc.d logstash defaultsupdate-rc.d: using dependency based boot sequencing
至此服务器B也安装配置完成,根据日志采集端的需要可以配置N个服务B
如何查看日志:
1、查看redis日志
cat /var/log/redis/redis-server.log
2、查看elasticsearch日志
cat /var/log/elasticsearch/elasticsearch.logtail -300f /var/log/elasticsearch/elasticsearch.log
3、查看logstash日志
cat /var/log/logstash/logstash.errtail -30f /var/log/logstash/logstash.err
4、查看kibana日志
cat /opt/kibanalog/nohup.outtail -30f /opt/kibanalog/nohup.out
错误处理
1)unable to fetch mapping, do you have indices matching the pattem?
kibana 报这个错误就是因为没有从logstash 过来任何数据一般检查一下数据传输
