ansible-playbook之安装filebeat部署

早安地球 2023-04-14 阅读 62
jsonfilebeatansible-playbookpolicyaliases运维yyds干货盘点

一.准备环境：

1.centos7 环境

2.安装ansible环境

3.filebeat安装文件下载路径：

       https://artifacts.elastic.co/downloads/kibana/kibana-8.6.2-linux-x86_64.tar.gz

4.filebeat安装，作者用192.168.126.128作为filebeat安装环境


二.规划：

1.变量规划：

安装路径：   filebeat_dir: "/kingdee/yzj_monitor"

运行用户：   filbeat_user: "filebeat"

安装包版本： filebeat_tgz: "kibana-8.6.2-linux-x86_64.tar.gz"

es服务端：   elasticsearch_host："192.168.126.128:9200,192.168.126.129:9200,192.168.126.130:9200"

写入索引：   myindex："applog"

索引副本数： number_of_replicas： 0

索引分片数： number_of_shards： 1

需要读取的日志路径：

appnameinfo:

  - {servername: "systemlog",logpath: "/var/log/messge*"}

  - {servername: "mytestlog",logpath: "/kingdee/*.log"}

es用户名称：esusername: "logadmin"

es用户密码：espassword: "Mytest@@@@@1203"


2.filebeat目录规划：

安装目录：/kingdee/yzj_monitor


三.编写ansible-playbook：

1.创建ansible-playbook剧本目录 

mkdir -p roles/filebeat/{files,tasks,templates,vars}

2.模板文件配置 

cd roles/filebeat/templates

#filebeat配置文件

vim filebeat.yml.j2

###定义配置文件路径######
filebeat.config.inputs:
  path: {{filebeat_dir}}/filebeat/config/*.yml
  enabled: true


###定义filebeat日志文件路径####
logging.level: info
logging.to_files: true
logging.files:
  path: {{filebeat_dir}}/filebeat/logs
  keepfiles: 3
  name: filebeat.log


###写入elasticsearch库中######
output.elasticsearch:
  hosts: ["http://{{elasticsearch_host.split(',')[0]}}","http://{{elasticsearch_host.split(',')[1]}}","http://{{elasticsearch_host.split(',')[2]}}"]    ##es的ip及端口
  index: "{{myindex}}"                    ##创建的索引名
  username: "{{esusername}}"               ##es的账号
  password: "{{espassword}}"           ##es的密码
setup.template.name: "{{myindex}}"      ##保持和index一致即可
setup.template.pattern: "{{myindex}}-*" ##保持和index-*即可
setup.ilm.enabled: false


#日志文件配置

vim app_log.yml.j2

{%for appname in appnameinfo%}
- type: log
  paths:
    - {{appname.logpath}}
  #exclude_lines: [^DBG]
  #exclude_files: [.gz]
  fields:
     host: {{ansible_ssh_host}}
     type: {{appname.servername}}
  fields_under_root: true
  scan_frequency: 5s
  multiline.pattern: ^\[
  multiline.negate: true
  multiline.match: after
  multiline.max_lines: 500
  multiline.timeout: 5s
{%endfor%}


#生成别名索引文件

vim myindex.json.j2

{
  "aliases": {
    "{{myindex}}": {
      "is_write_index": true
    }
  },
  "settings": {
    "number_of_replicas": {{number_of_replicas}},
    "number_of_shards": {{number_of_shards}}
  }
}


#生成生命周期文件【根据实际生产需求、设置host.warm.cold.delete阶段条件】

vim policy.json.j2

{
  "policy": {
    "phases": {
      "hot": {
        "actions": {
          "rollover": {

            "max_docs": "20000000",
            "max_size": "10gb"
          }
        }
      },

          }
        }
      },
      "cold": {
        "min_age": "2d",
        "actions": {
          "allocate": {
            "include": {
              "box_type": "cold"
            }
          }
        }
      },
      "delete": {
        "min_age": "3d",
        "actions": {
          "delete": {}
        }
      }
    }
  }
}


#生成模板文件

vim template.json.j2

{
  "order": 1,
  "index_patterns": [
    "{{myindex}}-*"
  ],
  "settings": {
    "number_of_shards": {{number_of_shards}},
    "number_of_replicas": {{number_of_replicas}},
    "index.lifecycle.name": "{{myindex}}_policy",
    "index.lifecycle.rollover_alias": "{{myindex}}",
    "index.routing.allocation.include.boxtype": "all"
  }
}


#设置集群检测生命周期配置

vim cluster_settings.json.j2

{
  "persistent": { #永久设置
    "indices": {
      "lifecycle": {
        "poll_interval": "1h" 
      }
    }
  },
  "transient": {  #临时设置
    "indices": {
      "lifecycle": {
        "poll_interval": "1h"
      }
    }
  }
}


#手动绑定生命周期【注：一般不需要设置这项，作者只是提醒各位大佬，需要手动设置的索引，这样设置就OK】

vim settings.json.j2

{
  "settings": {
    "index.lifecycle.name": "{{myindex}}_policy",
    "index.lifecycle.rollover_alias": "{{myindex}}",
  }
}

    "index.number_of_replicas": 0
  }
}


#主任务文件

vim main.yml

---
- include_tasks: install_filebeat.yml
- include_tasks: create_applog.yml


三.拿取安装包文件

cd role/filebeat/files

wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-8.6.1-linux-x86_64.tar.gz -O filebeat-8.6.1-linux-x86_64.tar.gz


整体ansible-playbook文件目录如下：

ansible-playbook之安装filebeat部署_ansible-playbook


四.编写hosts文件，与roles文件在同级目录：

vim hosts

[filebeat]
filebeat1 ansible_ssh_host=192.168.126.128


五.编写运行yml文件,与roles文件在同级目录：

vim startinstall_filebeat.yml

---
- hosts: filebeat
  remote_user: yzj
  gather_facts: no
  become: no
  vars:
    - appnameinfo:
        - {servername: "systemlog",logpath: "/var/log/messge*"}
        - {servername: "mytestlog",logpath: "/kingdee/*.log"}
    - filebeat_dir: "/kingdee/yzj_monitor"
    - filebeat_tgz: "filebeat-8.6.1-linux-x86_64.tar.gz"
    - filebeat_user: "filebeat"
    - esusername: "logadmin"
    - espassword: "Kingdee@1203"
    - elasticsearch_host: "192.168.126.128:9200,192.168.126.129:9200,192.168.126.130:9200"
    - myindex: "huawei123"
    - number_of_replicas: 0
    - number_of_shards: 1

  roles:
    - role: filebeat


六.运行elasticsearch安装脚本：

ansible-playbook -i hosts startinstall_filebeat.yml

ansible-playbook之安装filebeat部署_ansible-playbook_02


#查看状态：

curl http://192.168.126.128:9200/applog/_settings?pretty --user logadmin:Mytest@@@@@1203'

至此，ansible-playbook部署filebeat+elasticsearch+kibana已经完成，我们后面将进行下一章，挑战一下k8s使用ansible-playbook,进行部署；感谢各位读者大佬！！
