Socialhome requires a Linux server with root access. It is not possible to install Socialhome on a shared server.
Socialhome isn’t particularly heavy, though obviously that depends on the amount of users and connections to remote nodes. In default set up, Socialhome will be running the following:
- uWSGI (~200mb)
- Daphne (~60mb)
- Circus (~25mb)
- 5x RQ workers (~75mb each == 375mb)
- RQ scheduler (~75mb)
Memory values are taken from a running production instance. This gives a total of 735mb of RAM used by the application. Additionally, you need to allocate for PostgreSQL and Redis. A few gigabytes of available memory should easily be enough to run a node with medium activity.
Disk space will mostly be required for content and image uploads. As an example of database size, 100K content objects takes approx 230mb in the database. Image upload disk requirements depends entirely on the sizes of the uploads.
These instructions are for a production installation. For development installation instructions, see the Development pages.
If you have issues following these instructions, please contact us via Community.
The recommended installation method is using the official Docker images. Other guides will possibly be out of date and will likely be removed from the official documentation at some point.
The Docker images are relatively new, but have had some real production testing.
Currently the main application of Socialhome is packaged as one image. Inside the image there is a single Circusd process which runs 1) gunicorn, 2) django daphne, 3) a channels worker and 4) X amount of RQ worker processes. It’s possible we will extract various components into separate Docker images in the future.
In addition to the main image, the following are needed:
- Nginx or similar to serve media and/or provide SSL
Find the Socialhome images in the Docker registry.
This guide is very opinionated and experienced sysadmins will most likely want to do things differently. This guide will give you a Socialhome production install on uWSGI using an Apache2 web server.
This guide is written for Ubuntu 14.04 (with Upstart). For a SystemD config file, see Other Linuxes or newer Ubuntu using SystemD.
Ubuntu 14.04 has a problem with locales which could bring problems when installing PostgreSQL. If you have already installed PostgreSQL, you can probably skip this step.
Check these two commands:
echo $LANGUAGE echo $LC_ALL
if both of them come out empty, edit the file
/etc/default/locale and add the two following lines:
Save, logout and log back in.
See this post for example for a description of this problem.
Install system packages¶
# Generic packages needed sudo apt-get install git python-virtualenv python3-setuptools python-dev python3-dev build-essential # PostgreSQL dependencies sudo apt-get install libpq-dev # federation dependencies sudo apt-get install libxml2-dev libxslt-dev lib32z1-dev # Redis sudo apt-get install redis-server
Node.js version 10 has been tested to work. Install one by following the Node.js install guides.
If you already have a system Node installed which is either too old or newer, consider using [NVM](https://github.com/creationix/nvm) to install a specific version for Socialhome only.
If not installed or not using a remote PostgreSQL DB, install the database engine.
sudo apt-get install postgresql
Create a database and user. Note down password for later.
sudo su - postgres createuser -P socialhome createdb -O socialhome socialhome exit
Create a local user¶
It’s better to run applications under their own user.
sudo adduser socialhome --disabled-login sudo chmod 750 /home/socialhome # Add user group to www-data groups so we can protect users home folder sudo adduser www-data socialhome
Set up uWSGI¶
# Create logs path sudo -u socialhome mkdir /home/socialhome/logs
Create the ini file with
/home/socialhome/uwsgi.ini and add the following contents to it.
[uwsgi] chdir=/home/socialhome/socialhome module=config.wsgi:application master=True pidfile=/tmp/socialhome-master.pid vacuum=True max-requests=5000 logto=/home/socialhome/logs/uwsgi-master.log virtualenv=/home/socialhome/.virtualenvs/socialhome processes=2 threads=2 enable-threads=True socket=127.0.0.1:31452/ uid=socialhome gid=socialhome harakiri=30
Set up Apache¶
if not already installed, install the Apache2 web server.
sudo apt-get install apache2 libapache2-mod-proxy-uwsgi
Enable some necessary modules.
sudo a2enmod proxy_uwsgi sudo a2enmod proxy_wstunnel sudo a2enmod proxy sudo a2enmod ssl
Add an Apache virtualhost file
/etc/apache2/sites-available/socialhome.conf with the following content, replacing instances of
yourdomain.tld with your real domain for your Socialhome instance:
<VirtualHost *:80> ServerName yourdomain.tld ServerAlias www.yourdomain.tld RedirectPermanent / https://yourdomain.tld/ </VirtualHost> <VirtualHost *:443> ServerName yourdomain.tld ServerAlias www.yourdomain.tld ServerAdmin email@example.com Alias /robots.txt /home/socialhome/socialhome/staticfiles/robots.txt Alias /favicon.ico /home/socialhome/socialhome/staticfiles/favicon.ico Alias /media /home/socialhome/socialhome/socialhome/media <Directory /home/socialhome/socialhome/socialhome/media> Require all granted Options -MultiViews -Indexes </Directory> ProxyPass /media ! ProxyPass /ch/ ws://127.0.0.1:23564/ch/ ProxyPass / uwsgi://127.0.0.1:31452/ SSLEngine on SSLCertificateFile /etc/letsencrypt/live/yourdomain.tld/cert.pem SSLCertificateKeyFile /etc/letsencrypt/live/yourdomain.tld/privkey.pem SSLCertificateChainFile /etc/letsencrypt/live/yourdomain.tld/chain.pem </VirtualHost>
Enable Apache virtualhost
sudo a2ensite socialhome
Get LetsEncrypt certificate¶
We wouldn’t want to run our site without HTTPS. Install Certbot and get an LetsEncrypt certificate.
sudo apt-get install software-properties-common sudo add-apt-repository ppa:certbot/certbot sudo apt-get update sudo apt-get install python-certbot-apache
Launch Certbot and answer any questions to install the certificates.
certbot --apache certonly
Now you should be able to restart Apache.
sudo service apache2 restart
This is the easiest way to manage Python virtualenvs. We also add production Django configuration reference at the same time.
pip install --user virtualenvwrapper
Add the following lines to your
.bashrc and reload it via
export WORKON_HOME=$HOME/.virtualenvs source ~/.local/bin/virtualenvwrapper.sh export DJANGO_SETTINGS_MODULE=config.settings.production
Create Python virtualenv¶
Python 3.6+ is required! If your system Python 3 is not at least this version, please install Python 3.6 and replace
/usr/bin/python3 in the below command with the path to the Python 3.6 binary.
mkvirtualenv -p /usr/bin/python3 socialhome
The virtualenv is automatically activated. When you need it in the future, just type
Update pip and setuptools¶
pip install -U pip setuptools
pip-tools is a handy tool to keep environments clean and all dependencies nicely pinned.
pip install -U pip-tools
Install Python dependencies¶
We use the
pip-tools command to ensure dependencies are at the correct versions.
pip-tools are up to date:
# Ensure pip and setuptools are up to date as well pip install -U pip pip-tools
Then, update dependencies:
Create the file
.env with the following contents, replacing values as needed.
You must change or add the following values:
DATABASEPASSWORDHEREwith the database password typed in earlier.
DJANGO_SECRET_KEYmust be added. Generate one for example here.
- Place your domain in
DATABASE_URL=postgres://socialhome:DATABASEPASSWORDHERE@127.0.0.1:5432/socialhome DJANGO_SECRET_KEY= DJANGO_ALLOWED_HOSTS=yourdomain.tld DJANGO_SECURE_SSL_REDIRECT=True DJANGO_ACCOUNT_ALLOW_REGISTRATION=True SOCIALHOME_DOMAIN=yourdomain.tld SOCIALHOME_HTTPS=True SOCIALHOME_LOGFILE=/home/socialhome/logs/socialhome.log
For further configuration tips, see Running an instance.
Make the env file a bit less readable.
chmod 0600 .env
Configure email sending¶
Note, email is required for signing up. Users will not be able to sign up if the instance does not have working email sending. See DJANGO_EMAIL_BACKEND on how to configure email sending.
python manage.py migrate
npm install node_modules/.bin/bower install npm run build python manage.py collectstatic
The search indexes must be initialized, otherwise there will be an error when trying to use search. Run this command once:
python manage.py rebuild_index
Any further changes to indexes objects will be maintained automatically from this point onwards. If you ever need to rebuild the index from scratch, use the same command.
Set the correct domain name in Django¶
Load up the Django shell with
python manage.py shell_plus and then execute the following, replacing “yourdomain.tld” with your domain and “Socialhome” as the name of your site, assuming you want the name changed:
Site.objects.filter(id=1).update(domain="yourdomain.tld", name="Socialhome") exit
Set up Circus¶
Exit Socialhome user and create Upstart configuration for Circus process manager. Circus is used to control various processes that are needed in addition to the web server. This allows starting one process that will start and maintain a bunch of other processes we need. A configuration file for the processes is provided within the repository.
Create Upstart configuration
/etc/init/socialhome.conf with the following content:
description "Socialhome" start on runlevel  stop on runlevel  setuid socialhome setgid socialhome respawn env PYTHONPATH="/home/socialhome/socialhome" env SOCIALHOME_HOME="/home/socialhome" env RQWORKER_NUM=5 env VIRTUAL_ENV=/home/socialhome/.virtualenvs/socialhome env LC_CTYPE=en_US.UTF-8 env LC_ALL=C.UTF-8 env LANG=C.UTF-8 env DJANGO_SETTINGS_MODULE=config.settings.production chdir /home/socialhome/socialhome exec /home/socialhome/.virtualenvs/socialhome/bin/circusd config/circus.ini
Start Circus. It will automatically start on system boot.
sudo service socialhome start
For a SystemD config file, see Other Linuxes or newer Ubuntu using SystemD.
That wasn’t so hard was it? Navigate to the domain you chose to install Socialhome on and hopefully you will see a landing page. Signups will be open.
Unless you want to keep signups open, after creating your own account, you should close the signups to avoid random people signing up to your instance. See configuration tips at Running an instance.
If you didn’t configure emails, you cannot complete your user account registration without the email confirmation link. See Confirming user emails via the shell.
If you want to set your initially created user as admin, see Admin user.
Other Linuxes or newer Ubuntu using SystemD¶
Follow the Ubuntu 14.04 guide, tweaking it to your system. For SystemD, try the following service config (for example saved to
[Unit] Description=Socialhome Django script After=syslog.target network.target [Service] Environment=DJANGO_SETTINGS_MODULE="config.settings.production" Environment=PYTHONPATH="/home/socialhome/socialhome" Environment=SOCIALHOME_HOME="/home/socialhome" Environment=RQWORKER_NUM=5 Environment=VIRTUAL_ENV=/home/socialhome/.virtualenvs/socialhome User=socialhome Group=socialhome WorkingDirectory=/home/socialhome/socialhome ExecStart=/home/socialhome/.virtualenvs/socialhome/bin/circusd /home/socialhome/socialhome/config/circus.ini Restart=always [Install] WantedBy=multi-user.target
