一、问题描述

 

使用fluentd的mongodb插件，将nginx的日志，存储到mongodb数据库中，配置如下：

 

<source>
  @type tail
  path /var/log/nginx/access.log
  pos_file /var/log/td-agent/nginx.access_log.pos
  <parse>
    @type nginx
  </parse>
  tag nginx.access
</source>

<filter nginx.access.**>
@type stdout
</filter>

<match nginx.**>
  # plugin type
  @type mongo

  # mongodb db + collection
  database nginx
  collection access

  # mongodb host + port
  host 10.16.24.101
  port 27017

  user admin    # 使用admin账户
  password 密码  # admin账户的密码
  
  # interval
  <buffer>
    flush_interval 10s
  </buffer>

  # make sure to include the time key
  <inject>
    time_key time
  </inject>
</match>

 

 

发现，启动td-agent之后，并且生成了nginx的访问日志后，报错

二、问题分析

 

从上面的分析来看是用户认证的问题。

 

尝试以下的解决方案都没有解决：

 

• 修改admin账户对nginx库的权限
• 手动增加nginx库，和access 表

 

最终，通过下面的方法解决的问题

 

三、问题解决

 

1、使用admin账户登录到数据库

 

./mongo -u admin -p <password> admin

 

 

 

2、切换到nginx库，建立用户

 

use nginx

db.createUser({user:"root",pwd:"password",roles:[{role:"dbOwner",db:"nginx"}]})

 

 

3、修改td-agent.conf，使用新的用户

 

  user root                   # 修改为root，原来是admin
  password password   

 

 

4、重启td-agent

 

5、重新生成nginx的访问日志

 

发现，在mongodb中nginx库中可以看到访问日志记录

 

 

OK，问题完美的解决！

 

关键点：就是用户和权限！
