1.1、怎么修改filebeat默认索引格式

索引格式为：服务名称-域名-日志格式-时间（按月）

1）vim /etc/filebeat/filebeat.yml

filebeat.inputs:
- type: log
  enabled: true 
  paths:
    - /var/log/nginx/access.log
  json.keys_under_root: true
  json.overwrite_keys: true
output.elasticsearch:
  hosts: ["10.0.0.51:9200"]
  index: "nginx-www-access-%{[beat.version]}-%{+yyyy.MM}"
setup.template.name: "nginx"
setup.template.pattern: "nginx-*"
setup.template.enabled: false
setup.template.overwrite: true

2）systemctl restart filebeat.service

1.2、nginx修改多域名多日志

1）vim  /etc/nginx/nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
events {
    worker_connections 1024;
}
http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
   log_format   json '{ "time_local": "$time_local", '            ##添加此项，以json格式进行刷写日志
                           '"remote_addr": "$remote_addr", '
                           '"referer": "$http_referer", '
                           '"request": "$request", '
                           '"status": $status, '
                           '"bytes": $body_bytes_sent, '
                           '"agent": "$http_user_agent", '
                           '"x_forwarded": "$http_x_forwarded_for", '
                           '"up_addr": "$upstream_addr",'
                           '"up_host": "$upstream_http_host",'
                           '"upstream_time": "$upstream_response_time",'
                           '"request_time": "$request_time"'
    ' }';
    access_log  /var/log/nginx/access.log  json;
    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;
    include /etc/nginx/conf.d/*.conf;
}

2） [root@db01 /etc/nginx/conf.d]# cat bbs.conf   #配置子网页
server {
    listen 80;
    server_name  www.oldboy.com;
    location / {
        root /html/www;
        index index.html;
    }
    access_log  /var/log/nginx/www_access.log  json;
}

3）[root@db01 /etc/nginx/conf.d]# cat bbs.conf 
server {
    listen 80;
    server_name  bbs.oldboy.com;
    location / {
        root /html/bbs;
        index index.html;
    }
    access_log  /var/log/nginx/bbs_access.log  json;
}

4）[root@db01 /etc/nginx/conf.d]# cat blog.conf 
server {
    listen 80;
    server_name  blog.oldboy.com;
    location / {
        root /html/blog;
        index index.html;
    }
    access_log  /var/log/nginx/blog_access.log  json;
}

5）mkdir /html/{www,blog,bbs} -p
   echo "db01 www" > /html/www/index.html
   echo "db01 bbs" > /html/bbs/index.html               ##创建一个区别显示的首页文件
   echo "db01 blog" > /html/blog/index.html
   chown -R nginx:nginx /html/
   nginx -t
   systemctl restart nginx 

6）filebeat配置文件
vim /etc/filebeak/filebeak.yml

filebeat.inputs:
- type: log
  enabled: true 
  paths:
    - /var/log/nginx/bbs_access.log
  json.keys_under_root: true                              ##支持json格式的两个参数
  json.overwrite_keys: true                                  ##json重写索引
  tags: ["bbs"]                                                       ##关键字

- type: log
  enabled: true 
  paths:
    - /var/log/nginx/blog_access.log
  json.keys_under_root: true
  json.overwrite_keys: true
  tags: ["blog"]

- type: log
  enabled: true 
  paths:
    - /var/log/nginx/www_access.log
  json.keys_under_root: true
  json.overwrite_keys: true
  tags: ["www"]

- type: log
  enabled: true
  paths:
    - /var/log/nginx/error.log
  tags: ["error"]

output.elasticsearch:
  hosts: ["10.0.0.51:9200"]
  indices:
    - index: "nginx_www_access-%{[beat.version]}-%{+yyyy.MM}"
      when.contains:                 ###索引名称的重构
        tags: "www"                    ###当匹配到www的时候索引名字为上
    - index: "nginx_bbs_access-%{[beat.version]}-%{+yyyy.MM}"
      when.contains:
        tags: "bbs"
    - index: "nginx_blog_access-%{[beat.version]}-%{+yyyy.MM}"
      when.contains:
        tags: "blog"
    - index: "nginx_error-%{[beat.version]}-%{+yyyy.MM}"
      when.contains:
        tags: "error"

setup.template.name: "nginx"                      ###重写规则
setup.template.pattern: "nginx_*"                ##
setup.template.enabled: false                     ###关闭默认格式
setup.template.overwrite: true                    ###启用上面的规则

systemctl restart filebeat.service

1.3、收集tomcat日志

1.安装tomcat
yum install tomcat tomcat-webapps tomcat-admin-webapps tomcat-docs-webapp tomcat-javadoc -y

2.修改tomcat配置文件为json格式
vim /etc/tomcat/server.xml

第139行替换为：
pattern="{"clientip":"%h","ClientUser":"%l","authenticated":"%u","AccessTime":"%t","method":"%r","status":"%s","SendBytes":"%b","Query?string":"%q","partner":"%{Referer}i","AgentVersion":"%{User-Agent}i"}"/>

3.重启tomcat
systemctl restart tomcat

4.修改filebeat配置文件
filebeat.inputs:
- type: log
  enabled: true 
  paths:
    - /var/log/nginx/bbs_access.log
  json.keys_under_root: true
  json.overwrite_keys: true
  tags: ["bbs"]

- type: log
  enabled: true 
  paths:
    - /var/log/nginx/blog_access.log
  json.keys_under_root: true
  json.overwrite_keys: true
  tags: ["blog"]

- type: log
  enabled: true 
  paths:
    - /var/log/nginx/www_access.log
  json.keys_under_root: true
  json.overwrite_keys: true
  tags: ["www"]

- type: log
  enabled: true 
  paths:
    - /var/log/tomcat/localhost_access_log.*.txt
  json.keys_under_root: true
  json.overwrite_keys: true
  tags: ["tomcat"]

- type: log
  enabled: true 
  paths:
    - /var/log/nginx/error.log
  tags: ["error"]

output.elasticsearch:
  hosts: ["10.0.0.51:9200"]
  indices:
    - index: "nginx_www_access-%{[beat.version]}-%{+yyyy.MM}"
      when.contains:
        tags: "www"
    - index: "nginx_bbs_access-%{[beat.version]}-%{+yyyy.MM}"
      when.contains:
        tags: "bbs"
    - index: "nginx_blog_access-%{[beat.version]}-%{+yyyy.MM}"
      when.contains:
        tags: "blog"
    - index: "nginx_error-%{[beat.version]}-%{+yyyy.MM}"
      when.contains:
        tags: "error"
    - index: "tomcat_access-%{[beat.version]}-%{+yyyy.MM}"
      when.contains:
        tags: "tomcat"

setup.template.name: "nginx"
setup.template.pattern: "nginx_*"
setup.template.enabled: false
setup.template.overwrite: true

systemctl restart filebeat.service

  tags: ["java"]
  multiline.pattern: '^\['                                    ##通过此参数可以定义message行的范围
  multiline.negate: true                                   ##规则可以百度了解到
  multiline.match: after

output.elasticsearch:
  hosts: ["10.0.0.51:9200"]
  indices:
    - index: "nginx_www_access-%{[beat.version]}-%{+yyyy.MM}"
      when.contains:
