elasticsearch+logstash+kibana 初探

测试环境 centos6.3 64bit

/********************************************************/

安装：

elasticsearch [download]:

<pre>;Download and install the Public Signing Key
rpm --import http://packages.elasticsearch.org/GPG-KEY-elasticsearch 
#Add the following in your /etc/yum.repos.d/elasticsearch.repo
[elasticsearch-1.1]
name=Elasticsearch repository for 1.1.x packages
baseurl=http://packages.elasticsearch.org/elasticsearch/1.1/centos
gpgcheck=1
gpgkey=http://packages.elasticsearch.org/GPG-KEY-elasticsearch
enabled=1

#Install
yum install elasticsearch

logstash [download]:

#Add the key
rpm --import http://packages.elasticsearch.org/GPG-KEY-elasticsearch 
#Add the following in your /etc/yum.repos.d/logstash.repo
[logstash-1.4]
name=logstash repository for 1.4.x packages
baseurl=http://packages.elasticsearch.org/logstash/1.4/centos
gpgcheck=1
gpgkey=http://packages.elasticsearch.org/GPG-KEY-elasticsearch
enabled=1

#Install logstash with:
yum install logstash

kibana [download]

这个不用安装，解压然后放在httpd服务的目录里可以直接用是个纯html5应用（就是个网站），而且装在本机不需要配置，如果elasticsearch不在本机请编辑目录下的config.js指定url

/********************************************************/

配置：

elasticsearch 不需要配置，直接run起

P.S. 这个软件很奇葩，默认装的路径在 /usr/share 下。

logstash 配置文件默认是没有的，配置目录在 /etc/logstash/conf.d/

比如我在此目录下创建了一个配置文件

#/etc/logstash/conf.d/seven.conf
input {
file {
path => "/var/log/httpd/access_json.log"
type => "apache"

# This format tells logstash to expect 'logstash' json events from the file.
format => json_event
}
}

output {
elasticsearch {
host => "127.0.0.1"
}
}

解释一下，input 这里设置的apache日志格式是个json格式，这就意味着apache的日志要进行改造，这个方式比用redis，grok等方案更简单，apache的配置见后文。

重点注意：

#/etc/init.d/logstash
...
name=logstash
pidfile="/var/run/$name.pid"

#请把原来用户和用户组logstash改成root，不然没有权限读apache日志
LS_USER=root
LS_GROUP=root
LS_HOME=/var/lib/logstash
LS_HEAP_SIZE="500m"

kibana 这个也不用配置，直接可以跑

apache[download]

# Create a log format called 'logstash_json' that emits, in json, the parts of an http
# request I care about. For more details on the features of the 'LogFormat'
# directive, see the apache docs:
# http://httpd.apache.org/docs/2.2/mod/mod_log_config.html#formats LogFormat "{ \"@timestamp\": \"%{%Y-%m-%dT%H:%M:%S%z}t\", \"@fields\": { \"client\": \"%a\", \"duration_usec\": %D, \"status\": %s, \"request\": \"%U%q\", \"method\": \"%m\", \"referrer\": \"%{Referer}i\" } }" logstash_json

LogFormat "{ \"@timestamp\": \"%{%Y-%m-%dT%H:%M:%S%z}t\", \"@message\": \"%r\", \"@fields\": { \"user-agent\": \"%{User-agent}i\", \"client\": \"%a\", \"duration_usec\": %D, \"duration_sec\": %T, \"status\": %s, \"request_path\": \"%U\", \"request\": \"%U%q\", \"method\": \"%m\", \"referrer\": \"%{Referer}i\" } }" logstash_ext_json

# Write our 'logstash_json' logs to logs/access_json.log
CustomLog logs/access_json.log logstash_ext_json

提供的cookbook里还有让apache同时支持传统raw
data和json日志的方法，我没试过。
