environment-variables - Fluentd 环境变量未在进程中提取

问题描述

我正在使用 FluentD ( td-agent3) + Elastic Beanstalk ( ruby 2.6)。我使用环境变量FLUENTD_HOST来设置主机 ip，但是当我启动 Fluentd 时，主机不存在。

要启动服务，我使用：sudo systemctl start td-agent.service.

但是，一旦服务启动，该host字段为"".

2020-09-30 21:34:39 +0000 [warn]: #0 detached forwarding server 'dg-fluentd-1' host="" port=24224 phi=16.030025667476114 phi_threshold=16

配置文件

# /etc/td-agent/td-agent.conf

<source>
    type debug_agent
    bind 127.0.0.1
    port 24230
</source>

<source>
    @type tail
    path /var/log/secure
    pos_file /var/log/td-agent/secure.log.pos
    tag system.web.access
    format syslog
</source>

<source>
    @type tail
    path /var/log/nginx/*.log
    pos_file /var/log/td-agent/nginx.log.pos
    tag system.web.nginx
    format nginx
</source>

  <server>
    name dg-fluentd-1
    host "#{ENV['FLUENTD_HOST']}"
    port 24224
    heartbeat_type tcp
  </server>

# /etc/sysconfig/td-agent

export FLUENTD_HOST="<my-ip>"

我试过设置Environment=TD_AGENT_OPTIONS="--use-v1-config"，但没有选择环境变量。

我也试过更新相同的设置/etc/init.d/td-agent，也没有运气。

任何想法或想法表示赞赏！
