安装过程就不复述了，参考http://kibana.logstash.es/content/logstash/get_start/install.html
安装时注意的几个地方
1、java最好是1.7
2、server上的logstash我直接用rpm装的就能用，但是agent端的就不好使，没有深究
3、elasticsearch、kibana还有agent端的logstash我都是用supervisor运行的
4、supervisor直接就是epel的yum装的
贴下配置
192.168.122.187上：
Logstash的配置
server端的logstash是rpm安装的
# cat /etc/logstash/conf.d/central.confinput {redis { host => "192.168.122.1" port => 6379 type => "redis-input" data_type => "list" key => "logstash" codec => 'json'}}output {elasticsearch { host => "127.0.0.1"}}elasticsearch
/usr/local/elasticsearch-1.6.0/config/elasticsearch.yml保持默认Kibana
/usr/local/kibana-4.1.1-linux-x64/config/kibana.yml 保持默认192.168.122.1上
Redis的配置也没动。。。192.168.122.2上
Nginx的
#nginx这里的区别就是log这块的配置，配成json格式log_format json '{"@timestamp":"$time_iso8601",' '"host":"$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/zabbix_access.log json;logstash的

Bind的配置用默认的即可
Logstash的
# cat /usr/local/logstash/conf/shipper.confinput {file { type => "dnslog" path => ["/home/dnslog/*.log"]}}filter {#由于dns日志没办法定义成json，我又不会grok，所以这里用mutate来切割mutate { gsub => ["message","#"," "] split => ["message"," "]}mutate { add_field => { "client" => "%{}" "domain_name" => "%{}" "server" => "%{}" }}}output {stdout {}redis { host => "192.168.122.1" port => 6379 data_type => "list" key => "logstash"}}Supervisor的

Nginx
1、在discover搜索nginx相关的日志，之后保存
2、在visualize部署单个的图表，之后保存
3、在dashboard将几个nginx的visualize的图表连起来
Dns
1、在discover搜索dns相关的日志，之后保存
2、在visualize部署单个的图表，之后保存
3、在dashboard将几个dns的visualize的图表连起来
遇到的问题
自定义的field在discover上能看到，但是在制作visualize时看不到
这种情况是由于没有刷新索引的field导致的，默认的索引用的是logstash-*，在“Settings”—Indices中看到，点击logstash-*进去之后，点击刷新按钮
