最近做日志分析,发现logstash较符合自己的需求,
Logstash:做系统log收集,转载的工具。同时集成各类日志插件,对日志查询和分析的效率有很大的帮助。一般使用shipper作为log收集、indexer作为log转载。
Logstash shipper收集log 并将log转发给redis 存储
Logstash indexer从redis中读取数据并转发给elasticsearch
redis:是一个db,logstash shipper将log转发到redis数据库中存储。Logstash indexer从redis中读取数据并转发给elasticsearch。
Elasticsearch:elasticsearch是基于lucene的开源搜索引擎,用来做索引。
Kibana: 开源web展现,界面很漂亮,是一个功能强大的elasticsearch数据显示客户端,logstash已经内置了kibana,你也可以单独部署kibana,最新版的kibana3是纯html+js客户端。

我的环境如下
IP:192.168.81.44 t44 OS:CentOS6.5 x86_64 openjdk version "1.8.0_31" nginx-1.0.15 redis-2.4.10 elasticsearch-1.5.0 logstash-1.4.2 kibana-3.1.0
一、配置epel YUM源
yum -y localinstall http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
二、安装jdk环境
yum -y install java-1.8.0-openjdk
三、安装redis、启动redis
yum -y install redis ; /etc/init.d/redis restart
四、安装配置Elasticsearch、启动Elasticsearch
wget -c https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.5.0.tar.gz -O /root/elasticsearch-1.5.0.tar.gz tar -xvf /root/elasticsearch-1.5.0.tar.gz -C /usr/local/
添加2行配置:
tail -n2 /usr/local/elasticsearch-1.5.0/config/elasticsearch.yml http.cors.allow-origin: "/.*/" http.cors.enabled: true
启动Elasticsearch
/usr/local/elasticsearch-1.5.0/bin/elasticsearch -d
查看Elasticsearch日志
tail -f /usr/local/elasticsearch-1.5.0/logs/elasticsearch.log
五、安装配置Logstash、启动Logstash
wget -N https://download.elastic.co/logstash/logstash/logstash-1.4.2.tar.gz -O /root/logstash-1.4.2.tar.gz tar -xvf /root/logstash-1.4.2.tar.gz -C /usr/local/
配置index.conf
cat /usr/local/logstash-1.4.2/bin/index.conf input { redis { host => "127.0.0.1" # these settings should match the output of the agent data_type => "list" key => "logstash" # We use the ‘json‘ codec here because we expect to read # json events from redis. codec =>json } file { type =>"t44message" path =>["/var/log/messages"] } syslog { type => "rsyslog" port => 514 } file { type =>"t44secure" path =>["/var/log/secure"] } file { type =>"t44nginx" path =>["/var/log/nginx/*.log"] } } output { # stdout { debug => true debug_format => "json"} stdout { codec =>rubydebug } elasticsearch { host => "127.0.0.1" } }
启动Logstash
/usr/local/logstash-1.4.2/bin/logstash -f /usr/local/logstash-1.4.2/bin/index.conf
六、安装nginx、kibana
yum -y install nginx wget -c https://download.elasticsearch.org/kibana/kibana/kibana-3.1.0.tar.gz -O /root/kibana-3.1.0.tar.gz tar -xvf /root/kibana-3.1.0.tar.gz -C /usr/share/nginx/html/
配置nginx:
egrep -v ‘^#| #‘ /etc/nginx/conf.d/default.conf |grep -v ‘^$‘ server { listen 80 default_server; server_name _; include /etc/nginx/default.d/*.conf; location / { root /usr/share/nginx/html; index index.html index.htm index.php; } error_page 404 /404.html; location = /404.html { root /usr/share/nginx/html; } error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } location ~ \.php$ { root /usr/share/nginx/html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_buffer_size 32k; fastcgi_buffers 8 32k; include fastcgi_params; } }
配置kibana:
grep ‘elasticsearch:‘ /usr/share/nginx/html/kibana/config.js |grep -v ‘\*‘ elasticsearch: "http://192.168.81.44:9200", \cp /usr/share/nginx/html/kibana/app/dashboards/default.json{,.bak} \cp /usr/share/nginx/html/kibana/app/dashboards/logstash.json /usr/share/nginx/html/kibana/app/dashboards/default.json
