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
[yun@mini02 ~]$ /app/logstash/bin/logstash -f /app/logstash/config/redis_stdout.conf

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
