构建filebeat+redis+logstash+es+kibana架构
1、安装redis，并启动
1）准备安装和数据目录
[root@efk ~]# mkdir -p /data/soft
[root@efk ~]# mkdir -p /opt/redis_cluster/redis_6379/{conf,logs,pid}
2）下载redis安装包
[root@efk ~]# cd /data/soft
[root@efk soft]# wget http://download.redis.io/releases/redis-5.0.7.tar.gz
3）解压redis到/opt/redis_cluster/
[root@efk soft]# tar xf redis-5.0.7.tar.gz -C /opt/redis_cluster/
[root@efk soft]# ln -s /opt/redis_cluster/redis-5.0.7 /opt/redis_cluster/redis
4）切换目录安装redis
[root@efk soft]# cd /opt/redis_cluster/redis
[root@efk redis]# make && make install
5）编写配置文件
[root@efk redis]# vim /opt/redis_cluster/redis_6379/conf/6379.conf
bind 127.0.0.1 192.168.1.128
port 6379
daemonize yes
pidfile /opt/redis_cluster/redis_6379/pid/redis_6379.pid
logfile /opt/redis_cluster/redis_6379/logs/redis_6379.log
databases 16
dbfilename redis.rdb
dir /opt/redis_cluster/redis_6379
6）启动当前redis服务
[root@efk redis]# redis-server /opt/redis_cluster/redis_6379/conf/6379.conf
2、修改filebeat配置文件，output给redis
参考文档：https://www.elastic.co/guide/en/beats/filebeat/6.6/index.html
1）修改filebeat配置output指向redis，重启
[root@efk redis]# cd /etc/filebeat/
[root@efk filebeat]# mv filebeat.yml filebeat.yml.bak
[root@efk filebeat]# grep -v "#" filebeat.yml.bak | grep -v "^$" > filebeat.yml #过滤掉#开头及空行输出为filebeat.yml文件
[root@efk ~]# vim /etc/filebeat/filebeat.yml
filebeat.inputs:
- type: logenabled: truepaths:- /var/log/nginx/access.logjson.keys_under_root: truejson.overwrite_keys: truetags: ["access"]- type: logenabled: truepaths:- /var/log/nginx/error.logtags: ["error"]setup.template.settings:index.number_of_shards: 3setup.kibana:output.redis:hosts: ["192.168.1.128"]key: "filebeat"db: 0timeout: 5
[root@efk ~]# systemctl restart filebeat #重启服务
2）测试访问网站，登录redis，查看键值
清除之前的数据，以防看着碍眼：
测试访问网站
[root@efk ~]# ab -n 1000 -c 50 http://192.168.1.128/ #本机访问网站1000[root@ceshiji ~]# ab -n 100 -c 50 http://192.168.1.128/ #测试机访问网站300
[root@ceshiji ~]# ab -n 100 -c 50 http://192.168.1.128/
[root@ceshiji ~]# ab -n 100 -c 50 http://192.168.1.128/
登录redis，查看键值
[root@efk ~]# redis-cli #登录
127.0.0.1:6379> keys * #列出所有键
1) "filebeat"
127.0.0.1:6379> type filebeat #filebeat为键值名
list
127.0.0.1:6379> LLEN filebeat #查看list长度
(integer) 1300
127.0.0.1:6379> lrange filebeat 0 -1 #查看list所有内容（内容过多不宜展示）
3、安装logstash，收集redis的日志，提交给es
1）安装logstash(安装包提前放在了/data/soft下)
[root@efk ~]# cd /data/soft/
[root@efk soft]# rpm -ivh logstash-6.6.0.rpm
2）配置logstash
[root@efk soft]# vim /etc/logstash/conf.d/redis.conf
#添加：
input {redis {host => "192.168.1.128"port => "6379"db => "0"key => "filebeat"data_type => "list"}
}filter {mutate {convert => ["upstream_time","float"]convert => ["request_time","float"]}
}output {stdout {}elasticsearch {hosts => ["http://192.168.1.128:9200"]index => "nginx_access-%{+YYYY.MM.dd}"manage_template => false}
}
3）启动logstash
[root@efk soft]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/redis.conf
启动过程较为缓慢接着会报出许多传输的消息，这时可另启终端登录redis查看在redis的键值一直在减少
……"@timestamp" => 2020-08-05T04:06:21.813Z,"@version" => "1","offset" => 2115001,"up_addr" => "-","error" => {"type" => "json","message" => "@timestamp not overwritten (parse error on 05/Aug/2020:12:06:20 +0800)"},"up_host" => "-","prospector" => {"type" => "log"}
}
……
127.0.0.1:6379> LLEN filebeat
(integer) 590
127.0.0.1:6379> LLEN filebeat
(integer) 362
127.0.0.1:6379> LLEN filebeat
(integer) 0
验证：
4）修改logstash配置文件，实现access和error日志分离
[root@efk ~]# vim /etc/logstash/conf.d/redis.conf
#修改添加：
input {redis {host => "192.168.1.128"port => "6379"db => "0"key => "filebeat"data_type => "list"}
}filter {mutate {convert => ["upstream_time","float"]convert => ["request_time","float"]}
}output {stdout {}if "access" in [tags] {elasticsearch {hosts => ["http://192.168.1.128:9200"]index => "nginx_access-%{+YYYY.MM.dd}"manage_template => false}}if "error" in [tags] {elasticsearch {hosts => ["http://192.168.1.128:9200"]index => "nginx_error-%{+YYYY.MM.dd}"manage_template => false}}
}
/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/redis.conf #重启logstash
故意制造错误日志：
[root@ceshiji ~]# ab -n 100 -c 50 http://192.168.1.128/errorrr
[root@ceshiji ~]# ab -n 100 -c 50 http://192.168.1.128/errorrr
[root@ceshiji ~]# ab -n 100 -c 50 http://192.168.1.128/errorrr
验证：
