ELK集群搭建（ElasticSearch Logstash Kinaba）

Logstash

1.1 安装

注：安装在需要收集日志的机器上。

cd /data/softs
sudo wget https://download.elastic.co/l...
sudo tar -zxf logstash-2.4.0.tar.gz
sudo mv logstash-2.4.0 /usr/local/logstash

1.2 创建配置

cd /usr/local/logstash
sudo vim logstash.conf
输入：

input {

file {
    path => ["/data/logs/error/program.error.log"]
    type => "error"
    tags => ["error"]
    start_position => "beginning"
    #sincedb_path => "/dev/null"
    codec => "json"
}
file {
    path => ["/data/logs/error/program.warning.log"]
    type => "warning"
    tags => ["warning"]
    start_position => "beginning"
    #sincedb_path => "/dev/null"
    codec => "json"
}
#file {
#    path => ["/data/logs/access/nginx.access.log"]
#    type => "access"
#    tags => ["access"]
#    start_position => "beginning"
#    codec => "json"
#}

}
output {

if "error" in [tags] {
    elasticsearch {
        hosts  => "10.0.0.23:9200"
        index  => "error_log"
    }
    stdout { codec=> rubydebug }
}
if "warning" in [tags] {
    elasticsearch {
        hosts  => "10.0.0.23:9200"
        index  => "warning_log"
    }
    stdout { codec=> rubydebug }
}
if "access" in [tags] {
    elasticsearch {
        hosts  => "10.0.0.23:9200"
        #index  => "access_log"
        index => "access_log_%{+YYYY.MM.dd}"
    }
    stdout { }
}

}

1.3 启动

sudo /usr/local/logstash/bin/logstash agent -f /usr/local/logstash/logstash.conf 2>>/data/logs/error/logstash.error.log &
