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 { }
    }
}
