Server

Preparation

The following list is all the libraries you need to install on your machine. """You should install all of them before you build seafile""".

Package names are according to Ubuntu 12.04. For other Linux distros, please find their corresponding names yourself.

  • libevent-dev (2.0 or later )
  • libcurl4-openssl-dev (1.0.0 or later)
  • libglib2.0-dev (2.28 or later)
  • uuid-dev
  • intltool (0.40 or later)
  • libsqlite3-dev (3.7 or later)
  • libmysqlclient-dev (5.5 or later)
  • libarchive-dev
  • libtool
  • libjansson-dev
  • valac
  • libfuse-dev

The following libraries need to be compiled from source.

  • libzdb [[http://www.tildeslash.com/libzdb/dist/libzdb-2.12.tar.gz](http://www.tildeslash.com/libzdb/dist/libzdb-2.12.tar.gz)]
  • libevhtp [[https://github.com/ellzey/libevhtp/archive/1.1.6.zip](https://github.com/ellzey/libevhtp/archive/1.1.6.zip)]

libzdb relies on two packages: re2c and flex.libevhtp can be build by cmake .; make; sudo make install. libevhtp"s version should be 1.1.6 or 1.1.7.

"""Seahub""" is the web front end of Seafile. It"s written in the [[http://djangoproject.com](http://djangoproject.com) django] framework. Seahub requires Python 2.6(2.7) installed on your server, and it needs the following python libraries:

  • [[https://www.djangoproject.com/download/1.5.2/tarball/](https://www.djangoproject.com/download/1.5.2/tarball/) django 1.5]
  • [[https://github.com/djblets/djblets/tarball/release-0.6.14](https://github.com/djblets/djblets/tarball/release-0.6.14) djblets]
  • sqlite3
  • simplejson (python-simplejson)
  • PIL (aka. python imaging library, python-image)
  • chardet
  • gunicorn

The module """argparser""" is required by the seafile-admin script which you"ll see later. If you use Python 2.7, """argparser""" is distributed with python"s standard library, so you don"t need to install it. But if you use Python 2.6, you should install it manually.

Before continue, make sure you have all the above libraries available in your system.

Prepare the directory layout

In the following sections, you"ll be guided to build and setup the seafile server step by step. Seafile server is consisted of several components. In order for them to function correctly, you must:

  • Follow our instructions step by step
  • Make sure your directory layout is exactly the same with the guide in each step.

First create the top level directory. In the following sections, we"ll use "/data/haiwen" as the top level directory.

cd /data/haiwen/
mkdir seafile-server
cd seafile-server

The currently layout is:

└── seafile-server

Get the source

First you should get the latest source of libsearpc/ccnet/seafile/seahub

Download the source tarball of the latest tag from

  • [[https://github.com/haiwen/libsearpc/tags](https://github.com/haiwen/libsearpc/tags)]
  • [[https://github.com/haiwen/ccnet/tags](https://github.com/haiwen/ccnet/tags)]
  • [[https://github.com/haiwen/seafile/tags](https://github.com/haiwen/seafile/tags)]
  • [[https://github.com/haiwen/seahub/tags](https://github.com/haiwen/seahub/tags)]

For example, if the latest released seafile client is 2.0.3, then just use the """v2.0.3-server""" tags of the four projects. You should get four tarballs:

  • libsearpc-2.0.3-server.tar.gz
  • ccnet-2.0.3-server.tar.gz
  • seafile-2.0.3-server.tar.gz
  • seahub-2.0.3-server.tar.gz

Create a folder haiwen/src, and uncompress libsearpc/ccnet/seafile source to it.

mkdir src
cd src
tar xf /path/to/libsearpc-2.0.3-server.tar.gz
tar xf /path/to/ccnet-2.0.3-server.tar.gz
tar xf /path/to/seafile-2.0.3-server.tar.gz

And uncompress seahub tarball to haiwen/seafile-server:

tar xf /path/to/seahub-2.0.3-server.tar.gz
mv seahub-2.0.3-server seahub

So far, The current directory layout is:

└── seafile-server
    └── seahub
    └── src
        ├── libsearpc-2.0.3-server
        ├── ccnet-2.0.3-server
        ├── seafile-2.0.3-server
        ├── ... (other files)

Building

To build seafile server, you need first build """libsearpc""" and """ccnet""".

libsearpc
./autogen.sh
./configure
make
make install
ccnet
./autogen.sh
./configure --disable-client --enable-server   # `export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig` if libsearpc is not found
make
make install
seafile
./autogen.sh
./configure --disable-client --enable-server
make
make install

Deploy Seafile Server

Components of the Seafile Server

The seafile server consists of the following components:

Process Name Functionality
ccnet-server underlying networking
seaf-server data management
Seahub website front-end of seafile server
fileserver handles raw file upload/download for Seahub

[[images/server-arch.png]]

  • """ccnet""" stores its configuration and metadata is a directory named ccnet.
  • """seaf-server""" store its configuration and data in a directory, normally named seafile-data.
  • """seahub""" is written in Django. If you have any experience with Django, you should know the syncdb command must be run to create all the database tables.
  • An """admin account""" has to be created, so that you, the admin, can login with this account to manage the server.

These are the essential steps to create the configuration:

  • ensure seafile is already installed and all the python libraries seahub needs are installed.
  • create the ccnet configuration with the """ccnet-init""" program
  • create the seafile configuration with """seaf-server-init""" program
  • run Django """syncdb""" command for seahub
  • create an admin account for the seafile server

To create the configurations, you can either:

  • use the seafile-admin script(see below)
  • [[create server configuration by hand]]

Create Configurations with the seafile-admin script

seafile-admin should have been installed to system path after you have built and installed Seafile from source.


optional arguments:
  -h, --help            show this help message and exit

subcommands:

  {setup,start,stop,reset-admin}
    setup               setup the seafile server
    start               start the seafile server
    stop                stop the seafile server
    reset-admin         reset seafile admin account

Go to the top level directory(in this guide it"s """/data/haiwen/"""), and run """seafile-admin setup""" to create all the configuration:

export PYTHONPATH=/data/haiwen/seafile-server/seahub/thirdpart
seafile-admin setup

The script would ask you a series of questions, and create all the configuration for you.

Name Usage Default Requirement
server name The name of the server that would be shown on the client 3 ~ 15 letters or digits
ip or domain The ip address or domain name of the server Make sure to use the right ip or domain, or the client would have trouble connecting it
ccnet port the tcp port used by ccnet 10001
seafile port tcp port used by seafile 12001
seafile fileserver port tcp port used by seafile fileserver 8082
admin email Email address of the admin account
admin password password of the admin account

This is a screenshot of the """seafile-admin setup""" command:[[images/seafile-admin-1.png]]

And a screenshot after setup is finished successfully:[[images/seafile-admin-2.png]]

At this time, the directory layout would be like this:

└── ccnet # ccnet config directory
    └── ccnet.conf # ccnet config file
└── seafile-data # seafile configuration and data
    └── seafile.conf # seafile config file
└── seahub-data/ # seahub data
└── seahub.db # seahub sqlite3 database
└── seahub_settings.py # custom settings for seahub
└── seafile-server
    └── seahub/
    └── seafile-{VERSION} # seafile source code

Start the Seafile Server

After configuration successfully created, run """seafile-admin start""" in the top directory to start the all components of Seafile. ( """You should always run the seafile-admin script in the top directory""" ).

seafile-admin start

At this moment, all the components should be running and seahub can be visited at """http://yourserver-ip-or-domain:8000"""

"""Note""" You may want to deploy seahub with nginx or apache. In this case, follow the instructions on [[Deploy Seafile Web With Nginx/Apache]].

Stop the Seafile Server

To stop seafile server, run """seafile-admin stop""".

seafile-admin stop

Upgrade the Seafile Server

When you want to upgrade to a new vesrion of seafile server, you need to:

  • Stop the seafile server if it"s running
seafile-admin stop
  • Get and latest source code and build libsearpc/ccnet/seafile, just as what you do in a fresh setup.
  • Run the upgrade script. The upgrade script mainly updates database used by seafile for you. For example, create a new database table that is used in the latest seafile server but not in the previous version.

Get and compile the latest libsearpc/ccnet/seafile

See the """Building""" section above.

Get the new seahub tarball and uncompress it

mv seahub/ seahub-old # move away the old seahub folder
tar xf /path/to/new/seahub-x.x.x-server.tar.gz
mv seahub-x.x.x-server seahub

Do the upgrade

  • copy the scripts/upgrade/ subdir outside

The upgrade scripts is distributed in the scripts/upgrade subdir of seafile source code, we need to copy it to """seafile-server""" directory before run the scripts.

cp -rf seafile-{version}/scripts/upgrade .

Continuous Upgrade (like from 1.1 to 1.2)

Continuous upgrade means to upgrade from one version of seafile server to the next version. For example, upgrading from 1.1.0 to 1.2.0 is a continuous upgrade.

"""Note:""" Minor upgrade, like upgrade from 1.3.0 to 1.3.1, is documented in a separate section below.

Say you are upgrading from 1.1.0 to 1.2.0, you should run the script """upgrade_1.1_1.2.sh""" in seafile-server directory.

./upgrade/upgrade_1.1_1.2.sh

Non-continous version upgrade(like from 1.1 to 1.3)

If you upgrade a few versions at once, e.g. from 1.1.0 to 1.3.0. The procedure is:

  • upgrade from 1.1.0 to 1.2.0
  • upgrade from 1.2.0 to 1.3.0

Just run the upgrade scripts in sequence.

Minor Upgrade (like from 1.3.0 to 1.3.1)

Minor upgrade Minor upgrade is like an upgrade from 1.3.0 to 1.3.1. For this type of upgrade, you only need to update the avatar link:

cp -rf avatars/* ../../../seahub-data/avatars/
rm -rf avatars
ln -s ../../../seahub-data/avatars
