ELK-elkstack-使用消息队列

       日志通过logstash收集到redis，之后从logstash从redis读取数据存入到ES

1. logstash使用redis测试

       通过标准输入到redis中

logstash配置与启动

[yun@mini03 config]$ pwd
/app/logstash/config
[yun@mini03 config]$ cat redis_test.conf 
input{
  stdin{}
}

filter{
}

output{
  redis {
    data_type => "list"
    # 生产环境需要规划
    db => 1
    host => "mini03"
    port => 6379
    key => "redis_test"
  }
}

### 使用yun用户即可
[yun@mini03 ~]$ /app/logstash/bin/logstash -f /app/logstash/config/redis_test.conf 
…………

redis查看

[root@mini03 ~]# redis-cli -h mini03 -p 6379
mini03:6379> select 1
OK
mini03:6379[1]> KEYS *  # 生产环境禁止使用该命令
1) "redis_test"
mini03:6379[1]> type redis_test
list
mini03:6379[1]> llen redis_test
(integer) 7
mini03:6379[1]> lindex redis_test -1
"{"host":"mini03","message":"654321zhags","@timestamp":"2018-08-29T13:58:02.184Z","@version":"1"}"

2. httpd日志收集到redis中

logstash配置与启动

[yun@mini03 config]$ pwd
/app/logstash/config
[yun@mini03 config]$ cat redis_httpd_test.conf 
input{
  file{
    path => ["/var/log/httpd/access_log"]
    type => "httpd-access-log"
    start_position => "beginning"
  }
}

filter{
}

output{
  redis {
    data_type => "list"
    # 生产环境需要规划
    db => 1
    host => "mini03"
    port => 6379
    key => "apache-access-log"
  }
}

#### 使用root用户，涉及权限
[root@mini03 ~]# /app/logstash/bin/logstash -f /app/logstash/config/redis_httpd_test.conf  # 使用root用户

       使用谷歌、火狐或者IE浏览器访问

redis查看

[root@mini03 ~]# redis-cli -h mini03 -p 6379
mini03:6379> select 1
OK
mini03:6379[1]> KEYS *
1) "apache-access-log"
2) "redis_test"
mini03:6379[1]> llen apache-access-log
(integer) 28
mini03:6379[1]> lindex apache-access-log -1
"{"message":"10.0.0.1 - - [29/Aug/2018:22:08:30 +0800] \"GET /aaabbb/?aaa=bbb HTTP/1.1\" 404 205 \"-\" \"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0\"","type":"httpd-access-log","path":"/var/log/httpd/access_log","host":"mini03","@timestamp":"2018-08-29T14:08:31.442Z","@version":"1"}"

　　

3. logstash从redis读取数据标准输出

       注意：该logstash在mini02上读取mini03上redis的数据

       读取之后先使用grok进行过滤

       之后进行标准输出【命令行输出】

logstash配置与启动

[yun@mini02 config]$ pwd
/app/logstash/config
[yun@mini02 config]$ cat redis_stdout.conf 
input{
  redis {
    data_type => "list"
    db => 1
    host => "mini03"
    port => 6379
    key => "apache-access-log"
  }
}

filter{
  grok {
    match => { "message" => "%{HTTPD_COMBINEDLOG}" }
  }
}

output{
  stdout { codec => rubydebug }
}

4. elkstack-使用redis作为消息队列【汇总】

       在mini03的logstash读取httpd的日志，并存储到redis

4.1. mini03的 logstash配置如下：

[yun@mini03 config]$ pwd
/app/logstash/config
[yun@mini03 config]$ cat redis_httpd_test.conf 
input{
  file{
    path => ["/var/log/httpd/access_log"]
    type => "httpd-access-log"
    start_position => "beginning"
  }
}

filter{
}

output{
  redis {
    data_type => "list"
    # 生产环境需要规划
    db => 1
    host => "mini03"
    port => 6379
    key => "apache-access-log"
  }
}

######## 使用root用户，涉及权限
[root@mini03 ~]# /app/logstash/bin/logstash -f /app/logstash/config/redis_httpd_test.conf    
………………

       在mini02的logstash读取redis信息，并存储在ES

4.2. mini02的logstash配置

[yun@mini02 config]$ pwd
/app/logstash/config
[yun@mini02 config]$ cat redis_es.conf 
input{
  redis {
    data_type => "list"
    db => 1
    host => "mini03"
    port => 6379
    key => "apache-access-log"
  }
}

filter{
  grok {
    match => { "message" => "%{HTTPD_COMBINEDLOG}" }
  }
}

output{
  # es有3台，随便指定一台即可  也可以是多台如 ["127.0.0.1:9200","127.0.0.2:9200"]
  elasticsearch {
    hosts => ["mini01:9200", "mini02:9200", "mini03:9200"]
    index => "httpd-access-log-%{+YYYY.MM.dd}"
  }
}

####### 使用yun用户即可
