ES2	192.168.200.192	elasticsearch-node2
ES3	192.168.200.193	elasticsearch-node3
Logstash-Kibana	192.168.200.194	日志可视化服务器

18. tcp 0 0 0.0.0.0:6379 0.0.0.0:* LISTEN 15822/redis-server

 

4.3 在Web服务器上安装logstash

 

1. #yum安装jdk1.8
2. [root@WebServer ~]# yum -y install java-1.8.0-openjdk
3. #添加ELK的yum源文件
4. [root@WebServer ~]# vim /etc/yum.repos.d/elastic.repo
5. [root@WebServer ~]# cat /etc/yum.repos.d/elastic.repo
6. [elastic-6.x]
7. name=Elastic repository for 6.x packages
8. baseurl=https://artifacts.elastic.co/packages/6.x/yum
9. gpgcheck=1
10. gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
11. enabled=1
12. autorefresh=1
13. type=rpm-md
14. #yum安装logstash和filebeat
15. [root@WebServer ~]# yum -y install logstash filebeat
16. #创建收集数据写入redis的logstash配置文件
17. [root@WebServer ~]# vim /etc/logstash/conf.d/logstash-to-redis.conf
18. [root@WebServer ~]# cat /etc/logstash/conf.d/logstash-to-redis.conf
19. input {
20. file {
21. path => ["/var/log/messages"]
22. type => "system"
23. tags => ["syslog","test"]
24. start_position => "beginning"
25. }
26. file {
27. path => ["/var/log/audit/audit.log"]
28. type => "system"
29. tags => ["auth","test"]
30. start_position => "beginning"
31. }
32. }
33. filter {
34. }
35. output {
36. redis {
37. host => ["192.168.200.194:6379"]
38. password => "yunjisuan"
39. db => "0"
40. data_type => "list"
41. key => "logstash"
42. }
43. }
44. #启动WebServer服务器上的logstash
45. [root@WebServer ~]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/logstash-to-redis.conf
46. #验证logstash是否成功将数据写入redis
47. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan info Keyspace
48. # Keyspace
49. db0:keys=1,expires=0,avg_ttl=0
50. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan scan 0
51. 1) "0"
52. 2) 1) "logstash"
53. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan lrange logstash 0 1
54. 1) "{\"host\":\"WebServer\",\"message\":\"Jul 3 03:50:54 localhost journal: Runtime journal is using 6.0M (max allowed 48.7M, trying to leave 73.0M free of 481.1M available \xe2\x86\x92 current limit 48.7M).\",\"type\":\"system\",\"@version\":\"1\",\"@timestamp\":\"2018-08-24T13:03:55.486Z\",\"path\":\"/var/log/messages\",\"tags\":[\"syslog\",\"test\"]}"

56. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen logstash
57. (integer) 9068

 

4.4 在logstash-kibana服务器上配置读取redis数据的logstash配置文件

 

1. #在Logstash-Kibana进行如下操作
2. [root@Logstash-Kibana ~]# vim /etc/logstash/conf.d/logstash-from-redis.conf
3. [root@Logstash-Kibana ~]# cat /etc/logstash/conf.d/logstash-from-redis.conf
4. input {
5. redis {
6. host => "192.168.200.194"
7. port => 6379
8. password => "yunjisuan"
9. db => "0"
10. data_type => "list"
11. key => "logstash"
12. }
13. }
14. filter {
15. }
16. output {
17. if [type] == "system" {
18. if [tags][0] == "syslog" {
19. elasticsearch {
20. hosts => ["http://192.168.200.191:9200","http://192.168.200.192:9200","http://192.168.200.193:9200"]
21. index => "logstash-mr_chen-syslog-%{+YYYY.MM.dd}"
22. }
23. stdout { codec => rubydebug }
24. }
25. else if [tags][0] == "auth" {
26. elasticsearch {
27. hosts => ["http://192.168.200.191:9200","http://192.168.200.192:9200","http://192.168.200.193:9200"]
28. index => "logstash-mr_chen-auth-%{+YYYY.MM.dd}"
29. }
30. stdout { codec => rubydebug }
31. }
32. }
33. }

 

4.5 在ES1上启动图形化ES插件，清空ES上所有的索引

 

1. [root@ES1 ~]# cd elasticsearch-head/
2. [root@ES1 elasticsearch-head]# npm run start
3. > elasticsearch-head@0.0.0 start /root/elasticsearch-head
4. > grunt server
5. >> Local Npm module "grunt-contrib-jasmine" not found. Is it installed?
6. Running "connect:server" (connect) task
7. Waiting forever...
8. Started connect web server on http://localhost:9100

 

4.6 在logstash-kibana服务器上启动logstash，并查看kibana

 

1. #启动logstash
2. [root@Logstash-Kibana ~]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/logstash-from-redis.conf
3. #查看redis的key情况
4. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan info Keyspace
5. # Keyspace
6. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen logstash
7. (integer) 0

我们神奇的发现redis里的key已经全部都没有了 
这是因为redis在这里充当的是一个轻量级消息队列 
写入redis的logstash是生产者模型 
读取redis的logstash是消费者模型

重新创建好索引后，如下图

查看elasticsearch里索引的数据大小

 

五，引入Filebeat

filebeat优点：轻量。缺点：不支持正则 
logstash优点：支持正则提取。缺点：比较重，依赖于java

 

5.1 在WebServer上yum安装filebeat

 

1. #安装filebeat
2. [root@WebServer ~]# yum -y install filebeat
3. #修改filebeat配置文件
4. [root@WebServer ~]# cp /etc/filebeat/filebeat.yml{,.bak}
5. [root@WebServer ~]# egrep -v "#|^$" /etc/filebeat/filebeat.yml.bak > /etc/filebeat/filebeat.yml
6. #将配置文件修改成如下
7. [root@WebServer ~]# vim /etc/filebeat/filebeat.yml
8. [root@WebServer ~]# cat /etc/filebeat/filebeat.yml
9. filebeat.inputs:
10. - type: log
11. paths:
12. - /var/log/messages
13. tags: ["syslog","test"]
14. fields:
15. type: system
16. fields_under_root: true
17. - type: log
18. paths:
19. - /var/log/audit/audit.log
20. tags: ["auth","test"]
21. fields:
22. type: system
23. fields_under_root: true
24. output.redis:
25. hosts: ["192.168.200.194"]
26. password: "yunjisuan"
27. key: "filebeat"
28. db: 0
29. datatype: list
30. #启动filebeat进行数据收集测试
31. [root@WebServer ~]# systemctl start filebeat
32. #查看logstash-kibana服务器中的redis是否有数据
33. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
34. (integer) 9109

利用图形化软件清空ES中的索引，再开启logstash读取redis数据写入ES

 

1. #修改logstash配置文件
2. [root@Logstash-Kibana ~]# vim /etc/logstash/conf.d/logstash-from-redis.conf
3. [root@Logstash-Kibana ~]# cat /etc/logstash/conf.d/logstash-from-redis.conf
4. input {
5. redis {
6. host => "192.168.200.194"
7. port => 6379
8. password => "yunjisuan"
9. db => "0"
10. data_type => "list"
11. key => "filebeat" #修改本行的读取的redis的key即可
12. }
13. }
14. filter {
15. }
16. output {
17. if [type] == "system" {
18. if [tags][0] == "syslog" {
19. elasticsearch {
20. hosts => ["http://192.168.200.191:9200","http://192.168.200.192:9200","http://192.168.200.193:9200"]
21. index => "logstash-mr_chen-syslog-%{+YYYY.MM.dd}"
22. }
23. stdout { codec => rubydebug }
24. }
25. else if [tags][0] == "auth" {
26. elasticsearch {
27. hosts => ["http://192.168.200.191:9200","http://192.168.200.192:9200","http://192.168.200.193:9200"]
28. index => "logstash-mr_chen-auth-%{+YYYY.MM.dd}"
29. }
30. stdout { codec => rubydebug }
31. }
32. }
33. }
34. #清空ES数据后，启动logstash读取redis数据
35. [root@Logstash-Kibana ~]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/logstash-from-redis.conf
36. #查看redis的key被消费情况
37. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
38. (integer) 8359
39. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
40. (integer) 8109
41. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
42. (integer) 7984
43. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
44. (integer) 7859
45. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
46. (integer) 7359
47. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
48. (integer) 5234
49. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
50. (integer) 4484
51. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
52. (integer) 3734
53. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
54. (integer) 2984
55. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
56. (integer) 2484
57. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
58. (integer) 1984
59. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
60. (integer) 1609
61. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
62. (integer) 984
63. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
64. (integer) 0
65. [root@Logstash-Kibana ~]# redis-cli -a yunjisuan llen filebeat
66. (integer) 0

用浏览器访问tomcat

 

6.2.2 配置filebeat收集日志

catalina.out就是tomcat的堆栈日志

6.2.3 创建kibana的索引展示

 

6.3 Kibana可视化和仪表盘

在nginx访问日志的main格式中，模拟些不同的访问IP

 

1. 113.108.182.52
2. 123.150.187.130
3. 203.186.145.250
4. 114.80.166.240
5. 119.147.146.189
6. 58.89.67.152

8. [root@WebServer nginx]# for i in `seq 50`;do echo $a >> /usr/local/nginx/logs/access_main.log ;done

 

6.3.1 PV/IP

统计pv其实就是统计单位时间内的访问量

统计IP其实就是统计去重复以后的访问IP数

 

6.3.2 用户地理位置分布
