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 =>
     host => "mini03"
     port =>
     key => "redis_test"
   }
 }

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

 654321zhags

redis查看

 [root@mini03 ~]# redis-cli -h mini03 -p
 mini03:> select
 OK
 mini03:[]> KEYS *  # 生产环境禁止使用该命令
 ) "redis_test"
 mini03:[]> type redis_test
 list
 mini03:[]> llen redis_test
 (integer)
 mini03:[]> lindex redis_test -
 "{\"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 =>
     host => "mini03"
     port =>
     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 }
}

###### 使用yun用户即可

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 =>
     host => "mini03"
     port =>
     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 =>
     host => "mini03"
     port =>
     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
 [yun@mini02 ~]$ /app/logstash/bin/logstash -f /app/logstash/config/redis_es.conf
 ………………

4.3. 浏览器访问httpd

浏览器

 # 可以通过谷歌、火狐、IE访问
 http://mini03/
