檢視 Fluentd 的原始碼

'''Fluent'''是一套Log處理軟體。

== 簡介 ==

我是拿來跑server端（接收端）而非client端（發送端）。

== 安裝 ==

在[[Ubuntu]]上安裝：

<syntaxhighlight lang="bash">
curl -L https://packages.treasuredata.com/GPG-KEY-td-agent | gpg --dearmor | sudo tee /usr/share/keyrings/fluent-lts-archive-keyring.gpg > /dev/null; echo "Types: deb\nURIs: https://packages.treasuredata.com/lts/5/ubuntu/$(lsb_release -cs)/\nSuites: jammy\nComponents: contrib\nSigned-By: /usr/share/keyrings/fluent-lts-archive-keyring.gpg" | sudo tee /etc/apt/sources.list.d/fluent-lts.sources; sudo apt update; sudo apt install -y td-agent
</syntaxhighlight>

另外安裝fluent-plugin-slack：

<syntaxhighlight lang="bash">
sudo fluent-gem install fluent-plugin-slack
</syntaxhighlight>

== 設定 ==

我是透過[[nginx]]包裝成HTTPS服務，另外進行帳號密碼的管制（HTTP Authentication），主要的重點是：

<syntaxhighlight lang="nginx">
    location / {
        auth_basic "Restricted Content";
        auth_basic_user_file /srv/fluent.example.com/.htpasswd;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://127.0.0.1:8888/;
    }
</syntaxhighlight>

接著在<code>/etc/flient/fluent.conf</code>內的設定比較簡單：

<syntaxhighlight lang="apache">
#
<source>
  @type http
  port 9880
  bind 127.0.0.1
  add_remote_addr true
</source>

<match colo>
  @type copy
  <store>
    @type file
    path /var/log/fluent/
  </store>
  <store>
    @type slack
    channel fluentd
    flush_interval 5s
    message_keys log
    parse none
    title_keys REMOTE_ADDR
    title %s
    webhook_url https://hooks.slack.com/services/...
  </store>
</match>
</syntaxhighlight>

另外建立<code>/var/log/fluent</code>，要設為<code>td-agent</code>這個使用者：

<syntaxhighlight lang="bash">
sudo mkdir /var/log/fluent; sudo chown td-agent:td-agent /var/log/fluent
</syntaxhighlight>
