简介：
既然搭建了nextcloud，那么在线office协作是必不可少的功能。
简单看看nextcloud插件仓库，有这么几个可选项，逐个实验一下吧，顺便把安装配置介绍一下：
Nextcloud Office:
This application can connect to a Collabora Online (or other) server (WOPI-like Client). Nextcloud is the WOPI Host. Please read the documentation to learn more about that.
You can also edit your documents off-line with the Collabora Office app from the Android and iOS store.
ONLYOFFICE
ONLYOFFICE connector allows you to view, edit and collaborate on text documents, spreadsheets and presentations within Nextcloud using ONLYOFFICE Docs. This will create a new Edit in ONLYOFFICE action within the document library for Office documents. This allows multiple users to co-author documents in real time from the familiar web interface and save the changes back to your file storage.
Collabora Online - Built-in CODE Server
This app has to be installed and used together with the Collabora Online app.
Collabora Online is a powerful LibreOffice-based online office suite with collaborative editing, which supports all major documents, spreadsheet and presentation file formats and works together with all modern browsers.
This app provides a built-in server with all of the document editing features of Collabora Online. Easy to install, for personal use or for small teams. A bit slower than a standalone server and without the advanced scalability features.
The download is rather big so it is possible you experience a time-out when using the web interface. You can use the OCC command line tool to install the built-in server:
sudo -u wwwrun php -d memory_limit=512M ./occ app:install richdocumentscode
Where wwwrun is the user of your web server. This is www-data on Debian, Ubuntu and derivatives, wwwrun on SUSE based distributions, apache on Red Hat/Fedora and http on Arch linux and derivatives.
Updates can be done like this:
sudo -u wwwrun php -d memory_limit=512M ./occ app:update --all
Of course, alternatively you could increase memory usage and PHP time-outs by default, see the Nextcloud documentation.
适用于个人或小型团队，慢一点，且没有可扩展性，淘汰
Collabora Online - Built-in CODE Server (ARM64)
和上一个一样，for ARM64,淘汰。
Community Document Server
Document server for OnlyOffice, community edition.
The community document server is designed to make it easy to get OnlyOffice running in a Nextcloud instance without the need to setup an external document server, the community document server does not support all features of the official OnlyOffice document server and does not provide the same performance and scalability.
If you are setting up a larger instance or require the additional performance, please see https://onlyoffice.com for options for getting the official document server.
The community document server will automatically be configured if no other document server is configured for OnlyOffice.
Additionally, the community document server only supports running on x86-64 Linux servers.
社区文档服务器？不提供所有功能，不能扩展，淘汰。
Office Online integration
This application can connect to an Office Online server with Nextcloud.
office online server？贵，淘汰吧。
