Seafile 专业版服务器支持在线预览 office 文件，配置方法如下。

安装 Libreoffice/UNO

Office 预览依赖于 Libreoffice 4.1+ 和 Python-uno 库。

Ubuntu/Debian:

sudo apt-get install libreoffice libreoffice-script-provider-python poppler-utils

For older version of Ubuntu: sudo apt-get install libreoffice python-uno

Centos/RHEL:

sudo yum install libreoffice libreoffice-headless libreoffice-pyuno poppler-utils

其他 Linux 发行版可以参考: Installation of LibreOffice on Linux

你还需要安装字体文件:

Ubuntu/Debian:

# For ubuntu/debian
sudo apt-get install ttf-wqy-microhei ttf-wqy-zenhei xfonts-wqy

CentOS:

# For CentOS
sudo yum install wqy-microhei-fonts wqy-zenhei-fonts wqy-unibit-fonts -y

开启配置项

打开 conf/seafevents.conf, 添加:
```
[OFFICE CONVERTER]
enabled = true
```
保存后 seafevents.conf 重启 Seafile 服务 ./seafile.sh restart

其他配置选项

[OFFICE CONVERTER]
## How many libreoffice worker processes to run concurrenlty
workers = 1
## where to store the converted office/pdf files. Deafult is /tmp/.
outputdir = /tmp/
## how many pages are allowed to be previewed online. Default is 50 pages
max-pages = 50
## the max size of documents to allow to be previewed online, in MB. Default is 2 MB

Office 预览不能工作，日志文件在哪?

你可以查看 logs/seafevents.log

Office 预览不能工作的一个可能原因是你的机器上的 libreoffice 版本太低，可以用以下方法修复

删除安装的 libreoffice:

sudo apt-get remove libreoffice* python-uno python3-uno

从官网下载最新版 libreoffice official site，并安装

tar xf LibreOffice_4.1.6_Linux_x86-64_deb.tar.gz
cd LibreOffice_4.1.6.2_Linux_x86-64_deb
cd DEBS
sudo dpkg -i *.deb

重启 Seafile 服务

./seafile.sh restart
