Collabora Online Q & A 問題處理

這是在記錄 Collabora Online 遇到問題所處理的方法

更新後 loolwsd 服務無法正常運行

剛好在群組看到可以更新，但是更新後會有問題，所以我也來試著更新，結果一樣是有問題，那這個改版有增加一些新的功能及設定，遇到問題有兩個解決方式 版本 loolwsd 4.0 更新 loolwsd 4.2

方案1、使用 loolwsd 新版設定檔

更新後，系統會安裝一個新版的 loolwsd 設定檔，檔名為 loolwsd.xml.rpmnew ，直接修改這個檔案並且把副檔名改成 .xml 即可，那修改內容就之前設定一樣，請參考本站的記錄 NextCloud 結合 Collabora Online 線上編輯 裡面的 collabora 設定檔 即可，記得要重啟 loolwsd 服務

方案2、修改舊的 loolwsd 設定檔

直接修改舊版的，我是用使用 VSCode 編輯軟體來做兩個版本做比對修改，我是增加兩段語法之後重啟服務就可以正常運行了，其他微調的語法可以選擇性修改。
