If you really want to install everything manually, the below instructions
should work.

Install the following non-Python dependencies:
 * libffi-dev — needed for some Python extensions
 * postgresql 9.1 or later — our database (client, server, headers)
 * nodejs 0.10 (and npm)
 * memcached (and headers)
 * rabbitmq-server
 * libldap2-dev
 * python-dev
 * redis-server — rate limiting
 * tsearch-extras — better text search
 * libfreetype6-dev — needed before you pip install Pillow to properly generate emoji PNGs

### On Debian or Ubuntu systems:

#### Using the official Ubuntu repositories, PGroonga PPA and `tsearch-extras` deb package:

Start by cloning this repository: `git clone
https://github.com/zulip/zulip.git`

```
sudo apt-get install closure-compiler libfreetype6-dev libffi-dev \
    memcached rabbitmq-server libldap2-dev redis-server \
    postgresql-server-dev-all libmemcached-dev python-dev \
    hunspell-en-us nodejs nodejs-legacy npm git yui-compressor \
    puppet gettext postgresql

# Next, install PGroonga from its PPA
sudo add-apt-repository -y ppa:groonga/ppa
sudo apt-get update
# On 14.04
sudo apt-get install postgresql-9.3-pgroonga
# On 16.04
sudo apt-get install postgresql-9.5-pgroonga

# Next, install Zulip's tsearch-extras postgresql extension
# If on 14.04 or 16.04, you can use the Zulip PPA for tsearch-extras:
cd zulip
sudo apt-add-repository -yus ppa:tabbott/zulip
# On 14.04
sudo apt-get install postgresql-9.3-tsearch-extras
# On 16.04
sudo apt-get install postgresql-9.5-tsearch-extras


# Otherwise, you can download a .deb directly
# If on 12.04 or wheezy:
wget https://dl.dropboxusercontent.com/u/283158365/zuliposs/postgresql-9.1-tsearch-extras_0.1.2_amd64.deb
sudo dpkg -i postgresql-9.1-tsearch-extras_0.1.2_amd64.deb

# If on 14.04:
https://launchpad.net/~tabbott/+archive/ubuntu/zulip/+files/postgresql-9.3-tsearch-extras_0.1.3_amd64.deb
sudo dpkg -i postgresql-9.3-tsearch-extras_0.1.3_amd64.deb

# If on 15.04 or jessie:
wget https://dl.dropboxusercontent.com/u/283158365/zuliposs/postgresql-9.4-tsearch-extras_0.1_amd64.deb
sudo dpkg -i postgresql-9.4-tsearch-extras_0.1_amd64.deb

# If on 16.04 or stretch
wget https://launchpad.net/~tabbott/+archive/ubuntu/zulip/+files/postgresql-9.5-tsearch-extras_0.2_amd64.deb
sudo dpkg -i postgresql-9.5-tsearch-extras_0.2_amd64.deb
```

Alternatively, you can always build the package from [tsearch-extras
git](https://github.com/zulip/tsearch_extras).

Finally continue with the [All Systems](#all-systems) instructions below.

### All Systems:

Make sure you have followed the steps specific for your platform:

* [Debian or Ubuntu systems](#on-debian-or-ubuntu-systems)
* [Fedora 22 (experimental)](#on-fedora-22-experimental)
* [CentOS 7 Core (experimental)](#on-centos-7-core-experimental)
* [OpenBSD 5.8 (experimental)](#on-openbsd-5-8-experimental)
* [Fedora/CentOS](#common-to-fedora-centos-instructions)

For managing Zulip's python dependencies, we recommend using
[virtualenvs](https://virtualenv.pypa.io/en/stable/).

You must create two virtualenvs. One for Python 2 and one for Python 3.
You must also install appropriate python packages in them.

You should either install the virtualenvs in `/srv`, or put symlinks to
them in `/srv`.  If you don't do that, some scripts might not work correctly.

You can run `tools/setup/setup_venvs.py` to do this.  This script will create two
virtualenvs - /srv/zulip-venv and /srv/zulip-py3-venv.

If you want to do it manually, here are the steps:

```
virtualenv /srv/zulip-venv -p python2 # Create a python2 virtualenv
source /srv/zulip-venv/bin/activate # Activate python2 virtualenv
pip install --upgrade pip # upgrade pip itself because older versions have known issues
pip install --no-deps -r requirements/py2_dev.txt # install python packages required for development

virtualenv /srv/zulip-py3-venv -p python3 # Create a python3 virtualenv
source /srv/zulip-py3-venv/bin/activate # Activate python3 virtualenv
pip install --upgrade pip # upgrade pip itself because older versions have known issues
pip install --no-deps -r requirements/py3_dev.txt # install python packages required for development
```

Now run these commands:

```
./tools/setup/install-phantomjs
./tools/install-mypy
./tools/setup/download-zxcvbn
./tools/setup/emoji_dump/build_emoji
./scripts/setup/generate_secrets.py -d
if [ $(uname) = "OpenBSD" ]; then sudo cp ./puppet/zulip/files/postgresql/zulip_english.stop /var/postgresql/tsearch_data/; else sudo cp ./puppet/zulip/files/postgresql/zulip_english.stop /usr/share/postgresql/9.*/tsearch_data/; fi
./scripts/setup/configure-rabbitmq
./tools/setup/postgres-init-dev-db
./tools/do-destroy-rebuild-database
./tools/setup/postgres-init-test-db
./tools/do-destroy-rebuild-test-database
./manage.py compilemessages
sudo ./tools/setup/install-node
npm install
```

To start the development server:

```
./tools/run-dev.py
```

… and visit [http://localhost:9991/](http://localhost:9991/).

#### Proxy setup for by-hand installation

If you are building the development environment on a network where a
proxy is required to access the Internet, you will need to set the
proxy in the environment as follows:

- On Ubuntu, set the proxy environment variables using:
 ```
 export https_proxy=http://proxy_host:port
 export http_proxy=http://proxy_host:port
 ```

- And set the npm proxy and https-proxy using:
 ```
 npm config set proxy http://proxy_host:port
 npm config set https-proxy http://proxy_host:port
 ```
