阿里云 elk 搭建

1、logstash通过redis收集日志。 logstash > redis>logstash  >es

k8s日志挂载 tong
 sudo umount -t glusterfs 192.168.10.81:vol_b4c5f22a21e59e4388a65f9710b0e5e3   /app/bms_data_tmp

在日志收集机器安装logstash
[root@H-LAPP-V257 config]# cat  k8s_logstash.conf
input {
  file {
      path => ["/var/lib/kubelet/pods/*/volumes/kubernetes.io~glusterfs/pvc-cb9dc6bb-f3b2-11e8-a65f-801844f11504/lcrm-activity/*.log"]
      type => "lcrm_activity"
      start_position => "end"
      codec => multiline {
        charset => "UTF-8"
        pattern => "^.{32}\s{1}"
        negate => true
        what => "previous"
        }
    }

  file {
      path => ["/var/lib/kubelet/pods/*/volumes/kubernetes.io~glusterfs/pvc-b54723a4-bcb6-11e8-a65f-801844f11504/*.log"]
      type => "image"
      start_position => "end"
      codec => multiline {
        charset => "UTF-8"
        pattern => "^%{TIMESTAMP_ISO8601}"
        negate => true
        what => "previous"
        }
    }

  file {
      path => ["/var/lib/kubelet/pods/*/volumes/kubernetes.io~glusterfs/pvc-aa010360-eb5e-11ea-9f48-801844f11504/*.log"]
      type => "wk-app"
      start_position => "end"
      codec => multiline {
        charset => "UTF-8"
        pattern => "^%{TIMESTAMP_ISO8601}"
        negate => true
        what => "previous"
        }
    }

}
filter {
    mutate {
        replace => ["host", "192.168.9.175"]
    }
}
output {
    redis {
        host => "192.168.9.151"  ###redis 地址
        port => "6379"
        data_type => "list"
        key => "logstash:redis"

    }

}

2、redis 搭建

[yyapp@H-LOTH-V151 redis]$ cat redis.conf |grep -v "#" |grep -v "^$"
bind 0.0.0.0
protected-mode yes
port 6379
tcp-backlog 511
timeout 60
tcp-keepalive 300
daemonize yes
supervised no
pidfile /var/run/redis_6379.pid
loglevel notice
logfile "/log/redis/redis.log"
databases 16
save 900 1
save 300 10
save 60 10000
stop-writes-on-bgsave-error yes
slave-serve-stale-data yes
slave-read-only yes
repl-diskless-sync no
repl-diskless-sync-delay 5
repl-disable-tcp-nodelay no
slave-priority 100
maxmemory 6gb
no-appendfsync-on-rewrite no
lua-time-limit 5000
slowlog-log-slower-than 10000
slowlog-max-len 128
latency-monitor-threshold 0
notify-keyspace-events ""
hash-max-ziplist-entries 512
hash-max-ziplist-value 64
list-max-ziplist-size -2
list-compress-depth 0
set-max-intset-entries 512
zset-max-ziplist-entries 128
zset-max-ziplist-value 64
hll-sparse-max-bytes 3000
activerehashing yes
client-output-buffer-limit normal 0 0 0
client-output-buffer-limit slave 256mb 64mb 60
client-output-buffer-limit pubsub 32mb 8mb 60
hz 10

　2、 　logstash   输出到es

[yyapp@H-LOTH-V151 config]$ cat  log4j_to_es.conf
input {
    redis {
        host => "127.0.0.1"
        type => "redis-input"
        data_type => "list"
        key => "logstash:redis"
        codec => "json"
        batch_count => 125
        threads => 8
    }

}
output {
    elasticsearch {
        action => "index"
        hosts  => ["192.168.10.40","192.168.10.39","192.168.9.151"]
        index  => "%{type}_log_%{+YYYY.MM.dd}"
        flush_size => 5000
        idle_flush_time => 10
    }
}

3、es配置保证上面有磁盘1.5T

[yyapp@HM-LOTH-V168 config]$ cat  elasticsearch.yml  |grep -v  ""#  |grep -v  "^$"
cluster.name: yylending_elk_cluster
node.name: node_master_02
node.master: true
node.data: false
http.enabled: true
http.cors.enabled: true
http.cors.allow-origin: "*"
path.data: /app
path.logs: /log/es-logs
network.host: 0.0.0.0
http.port: 9200
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
discovery.zen.minimum_master_nodes: 2
discovery.zen.ping.unicast.hosts: ["192.168.10.39","192.168.10.40","192.168.9.151","192.168.10.87","192.168.10.88"]
