<p>最近在測試metabase，記得幾個月前就有測試過</p>
|
|
|
|
|
|
<p>但是當時的界面和現在的樣子差很多，看樣子改版還滿勤勞的</p>
|
|
|
|
|
|
<p>所以這次改用docker來建立，根本五分鐘不到就建好了(挖鼻孔)</p>
|
|
|
|
|
|
<p>不過呢，很討厭的是，一進去就發現語系採用的是簡體中文</p>

<p>因為工作上的需求，有個資料庫需要開放給不同team的人去存取</p>

<p>雖然都是在同一台機器上的同一個資料庫</p>

<p>這是發生在一個夜黑風高的寂寥深夜….. ( What The FXXX … )</p>
|
|
|
|
|
|
<p>來到這個環境之後，有一個很詭異的狀況一直困擾著我</p>
|
|
|
|
|
|
<p>在每個分公司，都會有一台伺服器作為KVM Host</p>
|
|
|
|
|
|
<p>上面跑兩台VM，一台作為ansible controller (目前沒作用)</p>
|
|
|
|
|
|
<p>另一台作為這邊所謂的 “Build Server”</p>
|
|
|
|
|
|
<p>用途包含了DHCP Server / Proxy Server (squid3) / APT Proxy (squid-deb-proxy)</p>
|
|
|
|
|
|
<p>問題就發生在這台 Build Server 上…</p>
