配置elk

1.启动es

#/usr/local/elk/es/bin/elasticsearch -d

2.配置并启动logstash 创建配置文件目录

#mkdir /usr/local/elk/logstash/etc

创建一个从日志文件读取，并写入redis的配置文件(本文件采用默认方式进行输入，输出)

#cat agent.conf
input {
    file {
        path => "/var/log/httpd/access_log"    //设置读取的日志路径
        sincedb_path => "../.sincedb"
        type => "httpd"
        start_position => "beginning"
    }
}
output {
    redis {
        host => ["127.0.0.1"]
        port => 6379
        batch => true
            batch_events => 5
            data_type => "list"
            key => "logstash:redis"
    }
}

配置一个从redis读取日志并输出到es的配置文件

#cat index.conf
input {
  redis {
    host => ["127.0.0.1"]
    port => 6379
    data_type => "list"
    key => "logstash:redis"
  }
}

output {
        elasticsearch {
        host => "127.0.0.1"
        protocol => "http"
        index => "logstash-%{type}-%{+YYYY.MM.dd}"
        index_type => "%{type}"
        }
}

启动logstash

#/usr/local/elk/logstash/bin/logstash -f /usr/local/elk/logstash/etc/agent.conf -l /var/log/elk/logstash/logstash.log &

#/usr/local/elk/logstash/bin/logstash -f /usr/local/elk/logstash/etc/index.conf -l /var/log/elk/logstash/logstash.log &

启动kibana

/usr/local/elk/kibana/bin/kibana &

写入开机启动

#cat /etc/rc.d/rc.local
/usr/sbin/ntpdate ntp.sjtu.edu.cn

/usr/local/elk/es/bin/elasticsearch -d

/usr/local/elk/logstash/bin/logstash -f /usr/local/elk/logstash/etc/agent.conf -l /var/log/elk/logstash/logstash.log &

/usr/local/elk/logstash/bin/logstash -f /usr/local/elk/logstash/etc/index.conf -l /var/log/elk/logstash/logstash.log &
