简介

这个Office文档在线预览功能是基于Nextcloud Collabora Online插件和在Docker上跑的Collabora Office。

通过Apache反向代理将Collabora Office代理至443端口，供Nextcloud通过HTTPS访问。

你需要

[ssbluelist]

2个子域名，分别用于Collabora Office和Nextcloud，且两个域名均拥有合法SSL证书。例如：cloud.orgleaf.com用于访问Nextcloud，office.orgleaf.com用于部署Collabora Office
一个在443端口正常运行的Nextcloud实例，并拥有合法SSL证书（最好不要用自签名证书）
一台可以运行Docker的公网VPS（建议系统为Ubuntu 14.0+）

[/ssbluelist]

在Docker上部署Collabora Office

首先安装Docker

sudo apt-get install docker.io

从DockerHub中拉取镜像：

sudo docker pull collabora/code
 Using default tag: latest
 latest: Pulling from collabora/code
 8aec416115fd: Pull complete 
 695f074e24e3: Pull complete 
 946d6c48c2a7: Pull complete

 db0e063f8c96: Pull complete 
 698261b49ccf: Pull complete 
 c8427a52a3b3: Pull complete

启动镜像：

[infobox]请将cloud.orgleaf.com替换为自己的域名（即用于访问Nextcloud的域名），注意主机名后面有一个"/"。[/infobox]

docker run -t -d -p 127.0.0.1:9980:9980 -e 'domain=cloud\\.orgleaf\\.com' --restart always --cap-add MKNOD collabora/code

如果要让这个Collabora Office同时服务于多个域名的话，需要在两个不同域名之间加上|，例如：

'domain=cloud\\.nextcloud\\.com\|second\\.nexcloud\\.com'

查看镜像是否启动：

root@cloud:/etc/apache2/sites-available# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                      NAMES
bcf8fe64b0ae        collabora/code      "/bin/sh -c 'bash sta"   1 second ago      Up 1 second      127.0.0.1:9980->9980/tcp   silly_stallman

反向代理的配置

激活Apache扩展：

a2enmod proxy proxy_wstunnel proxy_http ssl

激活扩展后，创建一个新的虚拟主机文件，把下面的内容粘贴进去：

注意要把<VirtualHost office.orgleaf.com:443>和ServerName office.orgleaf.com:443中的office.orgleaf.com替换为你自己的域名。

<VirtualHost office.orgleaf.com:443>
	ServerName office.orgleaf.com:443

	# SSL证书配置，请将SSLCertificateFile SSLCertificateChainFile指向你自己的证书
	SSLEngine on
	SSLCertificateFile /path/to/signed_certificate
	SSLCertificateChainFile /path/to/intermediate_certificate
	SSLCertificateKeyFile /path/to/private/key
	SSLProtocol             all -SSLv2 -SSLv3
	SSLCipherSuite ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS

另附Nginx方向代理的配置：

server {
    listen       443 ssl;
    server_name  collabora.example.com;

    ssl_certificate /path/to/ssl_certificate;
    ssl_certificate_key /path/to/ssl_certificate_key;

    # static files
    location ^~ /loleaflet {
        proxy_pass https://localhost:9980;
        proxy_set_header Host $http_host;
    }

    # WOPI discovery URL
    location ^~ /hosting/discovery {
        proxy_pass https://localhost:9980;
        proxy_set_header Host $http_host;
    }

    # main websocket
    location ~ ^/lool/(.*)/ws$ {
        proxy_pass https://localhost:9980;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_set_header Host $http_host;
        proxy_read_timeout 36000s;
    }

    # download, presentation and image upload
    location ~ ^/lool {
        proxy_pass https://localhost:9980;
        proxy_set_header Host $http_host;
    }

    # Admin Console websocket
    location ^~ /lool/adminws {
        proxy_pass https://localhost:9980;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_set_header Host $http_host;
        proxy_read_timeout 36000s;
    }
}

完成配置后，保存退出。
