We’ll assume that you have a freshly installed Digitalocean server, and have logged into it via ssh:

alias l='ls -lah --color'
apt-get update && apt-get install emacs

# Authentication:
LoginGraceTime 120
PermitRootLogin yes
StrictModes yes
AllowUsers haiwen

service ssh restart
useradd haiwen -s /bin/bash -m
adduser haiwen sudo
usermod -a -G www-data haiwen
passwd haiwen
apt-get install sudo
sed -i 's/main/main contrib non-free/g' /etc/apt/sources.list
apt-get update
locale-gen en_US.UTF-8

Now connect as user haiwen to ssh:

wget https://bitbucket.org/haiwen/seafile/downloads/seafile-server_4.1.2_x86-64.tar.gz
tar -xzf seafile-server_*
mkdir installed
mv seafile-server_* installed
cd seafile-server-4.1.2/
sudo apt-get install python2.7 python-setuptools python-imaging python-mysqldb mysql-server
