超簡單安裝nextcloud共筆功能collabora online Part II (v 2.4.17 )

2 年前

我以前文章「超簡單安裝collabora online」敘述如何讓nextcloud搭配online document server達到線上編輯功能；後來發現Onlyoffice 更好用，版面格式比較不會跑掉，就變心改用onlyoffice。

隨著公司越來越多人使用onlyoffice ，沒想到onlyoffice免費版有10人開啟檔案的上限，預算考量，只能另想辦法。

我回過頭來看collabora online ，雖是免費，但官方編譯一樣有20人數限制；照這樣子應該真的要去拍桌，跟老闆說要加錢購買onlyoffice。

可是偶然間發現有個群組，協助編譯開源版collabora online，並且解除20人限制，甚至編譯成 docker 版本，真是佛心來的。

以下請參考github與docker網站：

https://github.com/tiredofit/docker-collabora-online

https://hub.docker.com/r/tiredofit/collabora-online/tags

官方文件很少。但不囉嗦，我測試後直接寫如何安裝。

compose 文件

wget https://github.com/tiredofit/docker-collabora-online/raw/master/examples/docker-compose.yml
mv docker-compose.yml.traefik docker-compose.yml
vi docker-compose.yml

#2023/6/14
#2.4.17這版本pdf下載會出問題，因此更換2.4.34版，但是無法啟用成功，出現：
#ERROR: Cannot create container for service collabora-online-app: Conflict
#若要換新版本,需docker-compose down; docker rm collabora-online;
#修改yml檔案，改成新的版本號碼2.4.34後，再重新docker-compose up -d才能執行成功

nextcloud 設定
要安裝Collabora Online

設定URL，以後開檔案將導入到 Collabora Online-server 達到線上作業功能

完成了

檢查運行狀況
需輸入compose上面的管理者帳號與密碼

https://collabora-online.test.com/browser/dist/admin/admin.html

上傳字型，需要登入到容器，加上額外字型的設定

docker exec -it <容器名稱> bash
vi etc/coolwsd/coolwsd.xml
<remote_font_config>
  <url desc="URL of optional JSON file that lists fonts to be included in Online" type="string" default="">https://cloud.test.com/apps/richdocuments/settings/fonts.json</url>
</remote_font_config>

若nextcloud安裝pdf viewer 請停用，否則會衝突

唯讀請設定浮水印
這很重要，若公司被稽核，稽核員通常要求只能線上看ISO文件、程序書，且考慮版本無法管控，預設不可以下載

另外要設定安全機制WOPI，一樣是修改 coolwsd，只允許相關ip才能存取

docker exec -it <容器名稱> bash
vi etc/coolwsd/coolwsd.xml
