Config Seahub with Nginx

Deploy Seahub/FileServer with Nginx

Seahub is the web interface of Seafile server. FileServer is used to handle raw file uploading/downloading through browsers. By default, it listens on port 8082 for HTTP requests.

Here we deploy Seahub and FileServer with reverse proxy. We assume you are running Seahub using domain seafile.example.com.

This is a sample Nginx config file.

In Ubuntu 16.04, you can add the config file as follows:

1. create file /etc/nginx/sites-available/seafile.conf
2. Delete /etc/nginx/sites-enabled/default: rm /etc/nginx/sites-enabled/default
3. Create symbolic link: ln -s /etc/nginx/sites-available/seafile.conf /etc/nginx/sites-enabled/seafile.conf

server {
    listen 80;
    server_name seafile.example.com;

    proxy_set_header X-Forwarded-For $remote_addr;

    location / {
         proxy_pass         http://127.0.0.1:8000;
         proxy_set_header   Host $host;
         proxy_set_header   X-Real-IP $remote_addr;
         proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_set_header   X-Forwarded-Host $server_name;
         proxy_read_timeout  1200s;

         # used for view/edit office file via Office Online Server
         client_max_body_size 0;

         access_log      /var/log/nginx/seahub.access.log;
         error_log       /var/log/nginx/seahub.error.log;
    }

# If you are using [FastCGI](http://en.wikipedia.org/wiki/FastCGI),
# which is not recommended, you should use the following config for location `/`.
#
#    location / {
#         fastcgi_pass    127.0.0.1:8000;
#         fastcgi_param   SCRIPT_FILENAME     $document_root$fastcgi_script_name;
#         fastcgi_param   PATH_INFO           $fastcgi_script_name;
#
#         fastcgi_param     SERVER_PROTOCOL     $server_protocol;
#         fastcgi_param   QUERY_STRING        $query_string;
#         fastcgi_param   REQUEST_METHOD      $request_method;
#         fastcgi_param   CONTENT_TYPE        $content_type;
#         fastcgi_param   CONTENT_LENGTH      $content_length;
#         fastcgi_param     SERVER_ADDR         $server_addr;
#         fastcgi_param     SERVER_PORT         $server_port;
#         fastcgi_param     SERVER_NAME         $server_name;
#         fastcgi_param   REMOTE_ADDR         $remote_addr;
#          fastcgi_read_timeout 36000;
#
#         client_max_body_size 0;
#
#         access_log      /var/log/nginx/seahub.access.log;
#          error_log       /var/log/nginx/seahub.error.log;
#    }

    location /seafhttp {
        rewrite ^/seafhttp(.*)$ $1 break;
        proxy_pass http://127.0.0.1:8082;
        client_max_body_size 0;

        proxy_connect_timeout  36000s;
        proxy_read_timeout  36000s;
        proxy_send_timeout  36000s;

        send_timeout  36000s;
    }
    location /media {
        root /home/user/haiwen/seafile-server-latest/seahub;
    }
}

Nginx settings client_max_body_size is by default 1M. Uploading a file bigger than this limit will give you an error message HTTP error code 413 ("Request Entity Too Large").

You should use 0 to disable this feature or write the same value than for the parameter max_upload_size in section [fileserver] of seafile.conf. Client uploads are only partly effected by this limit. With a limit of 100 MiB they can safely upload files of any size.

Tip for uploading very large files (> 4GB): By default Nginx will buffer large request bodies in temp files. After the body is completely received, Nginx will send the body to the upstream server (seaf-server in our case). But it seems when the file size is very large, the buffering mechanism dosen't work well. It may stop proxying the body in the middle. So if you want to support file uploads larger than 4GB, we suggest to install Nginx version >= 1.8.0 and add the following options to Nginx config file:

    location /seafhttp {
        ... ...
        proxy_request_buffering off;
    }

Modify ccnet.conf and seahub_setting.py

Modify ccnet.conf

You need to modify the value of SERVICE_URL in ccnet.conf to let Seafile know the domain, protocol and port you choose. You can also modify SERVICE_URL via web UI in "System Admin->Settings". (Warning: If you set the value both via Web UI and ccnet.conf, the setting via Web UI will take precedence.)

SERVICE_URL = http://seafile.example.com

Note: If you later change the domain assigned to Seahub, you also need to change the value of SERVICE_URL.

Modify seahub_settings.py

You need to add a line in seahub_settings.py to set the value of FILE_SERVER_ROOT. You can also modify FILE_SERVER_ROOT via web UI in "System Admin->Settings". (Warning: if you set the value both via Web UI and seahub_settings.py, the setting via Web UI will take precedence.)

FILE_SERVER_ROOT = 'http://seafile.example.com/seafhttp'

Start Seafile and Seahub

./seafile.sh start
./seahub.sh start # or "./seahub.sh start-fastcgi" if you're using fastcgi
