Nginx日志从es替换到Doris记录

前言

生产现在Nginx日志，都是通过filebeat+logstash收集与转换到ES上，并通过Grafana进行可视化展示，部署详情查看：ELK-分析Nginx日志和Grafana可视化展示

现在存在一些问题在于，ES存的数据暂时未进行压缩，且其他同事学习成本也会增大（暂时只有我在维护），于是想着对es进行替换，期间也验证过ck数据库，但后面看到doris出了日志存储与分析这篇白皮书文章，就开始打算折腾一下能不能es替换到Doris。没想到经过几天研究与折腾验证还是可行的。而已只是简单修改logstash配置即可入库，影响面也很小。

操作

过程参考官方文档：https://doris.apache.org/zh-CN/docs/log-storage-analysis

环境准备

参考：https://199604.com/3212快速部署

因保密需要，只能展示测试环境，我测试环境，1台fe 2c6g,3台be 2c4g（其中一台与fe共用）,1台Doris Manager管理机

优化 FE 和 BE 配置

参考：https://doris.apache.org/zh-CN/docs/log-storage-analysis#%E7%AC%AC-3-%E6%AD%A5%E4%BC%98%E5%8C%96-fe-%E5%92%8C-be-%E9%85%8D%E7%BD%AE

因暂时考虑冷热存储数据，因此未对存储参数进行优化。

建表

因暂时考虑冷热存储数据，且暂时未使用云盘，因此与官方文档建表有出入，可自行判断。

采集日志

后面使用filebeat logstash的版本都是：7.17.27

**对接 filebeat **

因filebeat影响不大，与elk之前配置一致。自行检查：output.logstash下hosts配置

name: "192.168.111.105"

tags: ["192.168.111.105","nginx"]

filebeat.inputs:
  - type: log
    enabled: true
    paths:
      - "/AppHome/components/nginx/logs/access.log"

    fields:
      filetype: nginx
    fields_under_root: true

    json.keys_under_root: true
    json.overwrite_keys: true
    json.add_error_key: true

output.logstash:
  hosts: ["192.168.111.150:5044"]

# 没有新日志采集后多长时间关闭文件句柄，默认5分钟，设置成1分钟，加快文件句柄关闭
close_inactive: 1m

# 传输了3h后没有传输完成的话就强行关闭文件句柄，这个配置项是解决以上案例问题的key point
close_timeout: 3h

# 这个配置项也应该配置上，默认值是0表示不清理，不清理的意思是采集过的文件描述在registry文件里永不清理，在运行一段时间后，registry会变大，可能会带来问题
clean_inactive: 72h

# 设置了clean_inactive后就需要设置ignore_older，且要保证ignore_older < clean_inactive
ignore_older: 70h

# 限制 CPU和内存资源
max_procs: 1 # 限制一个CPU核心,避免过多抢占业务资源
queue.mem.events: 256 # 存储于内存队列的事件数，排队发送 (默认4096)
queue.mem.flush.min_events: 128 # 小于 queue.mem.events ,增加此值可提高吞吐量 (默认值2048)

运行：/AppHome/filebeat-7.17.27-linux-x86_64/filebeat -e -c filebeat.yml

对接 Logstash

参考：https://doris.incubator.apache.org/zh-CN/docs/ecosystem/logstash

可以从官网下载或者自行从源码编译 Logstash Doris output plugin。

  • 从官网下载
    • 不包含依赖的安装包 https://apache-doris-releases.oss-accelerate.aliyuncs.com/logstash-output-doris-1.0.0.gem
    • 包含依赖的安装包 https://apache-doris-releases.oss-accelerate.aliyuncs.com/logstash-output-doris-1.0.0.zip
安装插件
  • 普通安装

${LOGSTASH_HOME} 是 Logstash 的安装目录，运行它下面的 bin/logstash-plugin 命令安装插件

${LOGSTASH_HOME}/bin/logstash-plugin install logstash-output-doris-1.0.0.gem

Validating logstash-output-doris-1.0.0.gem
Installing logstash-output-doris
Installation successful

普通安装模式会自动安装插件依赖的 ruby 模块，对于网络不通的情况会卡住无法完成，这种情况下可以下载包含依赖的zip安装包进行完全离线安装，注意需要用 file:// 指定本地文件系统。

  • 离线安装
${LOGSTASH_HOME}/bin/logstash-plugin install file:///tmp/logstash-output-doris-1.0.0.zip

Logstash 配置

修改${LOGSTASH_HOME}/config/logstash.yml 文件

http.host: "0.0.0.0"
path.config: /opt/logstash-7.17.27/config/pipeline/
config.reload.automatic: true
config.reload.interval: 300s
#pipeline.batch.size: 500
#pipeline.batch.delay: 200
pipeline.batch.size: 1000000
pipeline.batch.delay: 10000

path.config: /opt/logstash-7.17.27/config/pipeline/ 为LOGSTASH的服务目录下，自行修改

新增配置文件logstash_nginx_doris_log.conf

mkdir -p /opt/logstash-7.17.27/config/pipeline/
touch logstash_nginx_doris_log.conf

查询和分析日志

image-20250116165854335

使用webui可视化日志分析

因为webui包含类 Kibana Discover 的日志检索分析界面，提供直观、易用的探索式日志分析交互。

image-20250116165950722

至此，替换es数据库，成功把elk模式替换到filebeat+logstash，入到doris数据库，并通过webui替换Kibana Discover 的日志检索分析。
