HOWTO : OwnCloud 9.0.2 and Hiawatha 10.2 on Ubuntu 16.04 LTS

Step 1 - Update Ubuntu :

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get autoclean
sudo apt-get --purge autoremove

Step 2 - Hiawatha Installation :

sudo apt-get install libc6-dev libssl-dev dpkg-dev debhelper fakeroot libxml2-dev libxslt1-dev

wget https://cmake.org/files/v3.5/cmake-3.5.2.tar.gz
tar -xvzf cmake-3.5.2.tar.gz
cd cmake-3.5.2
./configure
make
sudo make install

wget http://www.hiawatha-webserver.org/files/hiawatha-10.2.tar.gz
tar -xzvf hiawatha-10.2.tar.gz
cd hiawatha-10.2/extra
./make_debian_package
cd ..
sudo dpkg -i hiawatha_10.2_amd64.deb

sudo mkdir /etc/hiawatha/enable-sites

sudo nano /etc/hiawatha/hiawatha.conf

Add "SocketSendTimeout" just before "Binding Setting" :

SocketSendTimeout = 30

Add "MaxRequestSize" to "Binding Settings" :

# BINDING SETTINGS
# A binding is where a client can connect to.
#
Binding {
    Port = 80
    # MaxRequestSize is 100GB
    MaxRequestSize = 104857600
    MaxUploadSize = 2047
    TimeForRequest = 5,50
    MaxKeepAlive = 14400
}

Append the following line at the end of the file :

Include /etc/hiawatha/enable-sites/

Create "owncloud" file at /etc/hiawatha/enable-sites :

sudo nano /etc/hiawatha/enable-sites/owncloud

VirtualHost {
    Hostname = [your domain or IP address here]
    WebsiteRoot = /var/www/owncloud
    StartFile = index.php
    AccessLogfile = /var/log/hiawatha/owncloud-access.log
    ErrorLogfile = /var/log/hiawatha/owncloud-error.log
    TimeForCGI = 14400
    WebDAVapp = yes
    UseFastCGI = PHP70
    UseToolkit = denyData
    EnablePathInfo = yes
}

UrlToolkit {
    ToolkitID = denyData
    Match ^/data DenyAccess
}

FastCGIserver {
    FastCGIid = PHP70
    ConnectTo = /var/run/php/php7.0-fpm.sock
    Extension = php
    SessionTimeout = 14400
}

sudo nano /etc/php/7.0/fpm/php-fpm.conf

Append the following lines at the end of the file :

; for OwnCloud
env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp

[www]
pm.max_children=1000
pm.start_servers=50
pm.min_spare_servers=25
pm.max_spare_servers=75

Step 3 - MySQL Setting :

sudo mysql -u root -p

create database owncloud;
GRANT ALL ON owncloud.* TO owncloud@'127.0.0.1' IDENTIFIED BY '[your password here]';
flush privileges;
quit

Step 4 - OwnCloud Installation :

wget -nv https://download.owncloud.org/download/repositories/stable/Ubuntu_16.04/Release.key -O Release.key
sudo apt-key add - < Release.key

rm Release.key

sudo sh -c "echo 'deb http://download.owncloud.org/download/repositories/stable/Ubuntu_16.04/ /' >> /etc/apt/sources.list.d/owncloud.list"
sudo apt-get update
sudo apt-get install owncloud-files

sudo apt-get install exim4 exim4-base exim4-config exim4-daemon-light libapr1 libaprutil1 libaprutil1-dbd-sqlite3 libaprutil1-ldap liblua5.1-0 s-nail php-common php7.0-cli php7.0-common php7.0-curl php7.0-gd php7.0-imap php7.0-intl php7.0-json php7.0-mbstring php7.0-mcrypt php7.0-mysql php7.0-readline php7.0-xml php7.0-zip php7.0-pgsql php7.0-sqlite3 php7.0-fpm php-apcu mysql-server mysql-client php7.0-cgi

sudo nano /var/www/owncloud/.user.ini

The content of the file may looking like this one :

upload_max_filesize=100G
post_max_size=100G
memory_limit=12G
mbstring.func_overload=0
always_populate_raw_post_data=-1
default_charset='UTF-8'
output_buffering=0
max_input_time=3600
max_execution_time=3600
upload_tmp_dir='/tmp/'
max_file_upload=5000

sudo nano /var/www/owncloud/config/config.php

Insert the following line into the end of the block of the code :

'memcache.local' => '\OC\Memcache\APCu',

You may need to edit the following file at client sync program when necessary :

sudo nano /etc/ownCloud/sync-exclude.lst

To restart OwnCloud and Hiawatha services :

sudo /etc/init.d/php7.0-fpm restart
sudo /etc/init.d/hiawatha restart

Remarks :

If you want to have https connection, you need to generate the private SSL certificate or purchase one. You can also use Let's Encrypt when necessary. If so, the "binding settings" at Hiawatha should be "Port 443".

That's all! See you.
