需求说明1、在《ELK收集Apache的json格式访问日志并按状态码绘制图表》中，收集了Apache的json格式日志，在此实验基础上，增加nginx的json日志收集，并自定义filebeat的索引。本次实验也是基于《ELK收集Apache的json格式访问日志并按状态码绘制图表》；
2、将nginx和Apache的日志按照状态码绘制柱状图，并将其添加到dashboard；
10.0.0.101（test101）——部署apache、nginx、filebeat
10.0.0.102（test102）——部署elasticsearch、kibana
系统：centos7.3
备注：本次实验的重点在于怎样用filebeat收集多日志的json格式日志，并自定义索引，因此也没有装logstash。日志数据从filebeat——elasticsearch——kibana展示
1.1 安装nginx
[root@test101 conf]#yum -y install nginx1.2 修改配置文件将端口改成8080（因为80端口已经被Apache占用）
[root@test101 conf]# vim /etc/nginx/conf.d/default.conf
server {
listen 8080; #将默认的80端口改成80
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
...... #省略若干行
[root@test101 conf]# 1.3 编写index.html
在/usr/share/nginx/html/目录下编写了一个测试的index.html文件，以提供访问，生成日志：
当前生成的日志格式为：
[root@test101 nginx]# tailf /var/log/nginx/access.log
10.0.0.1 - - [17/Dec/2018:11:25:11 +0800] "GET / HTTP/1.1" 304 0 "-" "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36" "-"
10.0.0.1 - - [17/Dec/2018:11:25:11 +0800] "GET / HTTP/1.1" 304 0 "-" "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36" "-"
10.0.0.1 - - [17/Dec/2018:11:25:11 +0800] "GET / HTTP/1.1" 304 0 "-" "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36" "-"1.4 修改nginx输出格式为json格式
修改/etc/nginx/nginx.conf，注释掉文件中log_format和access_log，添加新的日志输出格式：
[root@test101 nginx]# cat -n nginx.conf
1
2 user nginx;
3 worker_processes 1;
4
5 error_log /var/log/nginx/error.log warn;
6 pid /var/run/nginx.pid;
7
8
9 events {
10 worker_connections 1024;
11 }
12
13
14 http {
15 include /etc/nginx/mime.types;
16 default_type application/octet-stream;
17 #注释掉下面部分内容（18-21行）：
18 #log_format main ‘$remote_addr - $remote_user [$time_local] "$request" ‘
19 # ‘$status $body_bytes_sent "$http_referer" ‘
20 # ‘"$http_user_agent" "$http_x_forwarded_for"‘;
21 #access_log /var/log/nginx/access.log main;
22 #添加新的日志输出格式（23-33行）
23 log_format main_json ‘{"@timestamp":"$time_local",‘
24 ‘"N_client_ip": "$remote_addr",‘
25 ‘"N_request": "$request",‘
26 ‘"N_request_time": "$request_time",‘
27 ‘"N_status": "$status",‘
28 ‘"N_bytes": "$body_bytes_sent",‘
29 ‘"N_user_agent": "$http_user_agent",‘
30 ‘"N_x_forwarded": "$http_x_forwarded_for",‘
31 ‘"N_referer": "$http_referer"‘
32 ‘}‘;
33 access_log /var/log/nginx/access.log main_json;
34
35
36 sendfile on;
37 #tcp_nopush on;
38
39 keepalive_timeout 65;
40
41 #gzip on;
42
43 include /etc/nginx/conf.d/*.conf;
44 }
[root@test101 nginx]#
}1.5 重启nginx，检查日志输出格式
重启nginx后，再访问nginx首页http://10.0.0.101:8080 ，可以看到日志格式已经变成了json格式：
[root@test101 nginx]# tailf /var/log/nginx/access.log
{"@timestamp":"17/Dec/2018:11:33:01 +0800","N_client_ip": "10.0.0.1","N_request": "GET / HTTP/1.1","N_request_time": "0.000","N_status": "304","N_bytes": "0","N_user_agent": "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36","N_x_forwarded": "-","N_referer": "-"}
{"@timestamp":"17/Dec/2018:11:33:02 +0800","N_client_ip": "10.0.0.1","N_request": "GET / HTTP/1.1","N_request_time": "0.000","N_status": "304","N_bytes": "0","N_user_agent": "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36","N_x_forwarded": "-","N_referer": "-"}
{"@timestamp":"17/Dec/2018:11:33:03 +0800","N_client_ip": "10.0.0.1","N_request": "GET / HTTP/1.1","N_request_time": "0.000","N_status": "304","N_bytes": "0","N_user_agent": "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36","N_x_forwarded": "-","N_referer": "-"}2.1 修改test101的filebeat配置文件，同时收集Apache和nginx的json日志，同时自定义索引
filebeat.yml文件修改两个地方：
1）修改 Filebeat inputs部分，增加nginx的日志采集
#=========================== Filebeat inputs =============================
filebeat.inputs:
# Each - is an input. Most options can be set at the input level, so
# you can use different inputs for various configurations.
# Below are the input specific configurations.
- type: log
enabled: true
paths:
- /var/log/httpd/access_log
json.keys_under_root: true
json.overwrite_keys: true
- type: log #增加nginx的日志收集内容
enabled: true
paths:
- /var/log/nginx/access.log
json.keys_under_root: true
json.overwrite_keys: true
2）修改Elasticsearch output 部分，增加索引配置
#-------------------------- Elasticsearch output ------------------------------
setup.template.name: "test101_web" #增加索引
setup.template.pattern: "test101_web-" #增加索引
output.elasticsearch:
# Array of hosts to connect to.
hosts: ["10.0.0.102:9200"]
index: "test101_web-%{+yyyy.MM.dd}" #增加索引
# Optional protocol and basic auth credentials.
#protocol: "https"
#username: "elastic"
#password: "changeme"3）删除kibana界面创建的索引和test102服务器上elasticsearch的索引：
[root@test102 ~]# curl 10.0.0.102:9200/_cat/indices
green open .kibana_1 udOUvbprSnKWUJISwD0r_g 1 0 3 0 62.8kb 62.8kb
[root@test102 ~]#4）重启test101的filebeat，生成新的索引：
[root@test102 filebeat]# curl 10.0.0.102:9200/_cat/indices
yellow open test101_web-2018.12.17 Rg31xncWSAm4oLER8DO5yg 5 1 45 0 589.4kb 589.4kb #新的索引
green open .kibana_1 udOUvbprSnKWUJISwD0r_g 1 0 6 0 34.5kb 34.5kb
[root@test102 filebeat]# 
2.2 在kibana重建索引，检查Apache和nginx日志收集的正确性：
Apache json日志：
nginx json日志：
以nginx图形为例：
在Visualize界面选择Vertical Bar图形
选择索引数据
配置X轴数据，点击预览，得到右边的图形：
保存为nginx-status：
同样，绘制Apache状态码图形。
注意，根据《ELK收集Apache的json格式访问日志并按状态码绘制图表》的配置，绘制图形的时候，在Field那里不是选择N_status.keywaord，而是选择status。
绘制完成后，将apache-status和nginx-status两张图标添加到dashboard：
保存dashboard：
dashboard界面图标绘制完成，刷新界面，status状态码动态刷新：
