Contents:

* [Installing directly on Ubuntu](#installing-directly-on-ubuntu)
* [Installing manually on Linux](#installing-manually-on-linux)
* [Using Docker (experimental)](#using-docker-experimental)

## Installing directly on Ubuntu

Start by [cloning your fork of the zulip repository](../contributing/git-guide.html#step-1b-clone-to-your-machine):

`git clone --config pull.rebase https://github.com/YOURUSERNAME/zulip.git`

If you'd like to install a Zulip development environment on a computer
that's already running Ubuntu 16.04 Xenial or Ubuntu 14.04 Trusty, you
can do that by just running:

```
# From a clone of zulip.git
./tools/provision
source /srv/zulip-py3-venv/bin/activate
./tools/run-dev.py  # starts the development server
```

Note that there is no supported uninstallation process without Vagrant
(with Vagrant, you can just do `vagrant destroy` to clean up the
development environment).

Once you've done the above setup, you can pick up the [documentation
on using the Zulip development
environment](../development/setup-vagrant.html#step-4-developing),
ignoring the parts about `vagrant` (since you're not using it).

## Installing manually on Linux

* [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 steps](#common-to-fedora-centos-instructions)
* [Steps for all systems](#all-systems)

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 yarn)
 * memcached (and headers)
 * rabbitmq-server
 * libldap2-dev
 * python3-dev
 * python-dev
 * python-virtualenv
 * 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 your fork of the zulip repository](../contributing/git-guide.html#step-1b-clone-to-your-machine):

`git clone --config pull.rebase https://github.com/YOURUSERNAME/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 python3-dev \
    python-dev python-virtualenv hunspell-en-us nodejs \
    nodejs-legacy git yui-compressor puppet gettext postgresql

# If using Ubuntu, install PGroonga from its PPA
sudo add-apt-repository -ys 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

# If using Debian, follow the instructions here: http://pgroonga.github.io/install/debian.html

# 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 -ys ppa:tabbott/zulip
sudo apt-get update
# 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:
wget 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 a Python 3 virtualenv.  You must also install appropriate
python packages in it.

You should either install the virtualenv in `/srv`, or put a symlink to it in
`/srv`.  If you don't do that, some scripts might not work correctly.

You can run `python3 tools/setup/setup_venvs.py`.  This script will create a
virtualenv `/srv/zulip-py3-venv`.

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

```
sudo virtualenv /srv/zulip-py3-venv -p python3 # Create a python3 virtualenv
sudo chown -R `whoami`:`whoami` /srv/zulip-py3-venv
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/dev_lock.txt # install python packages required for development
```

Now run these commands:

```
sudo ./scripts/lib/install-node
yarn install
sudo mkdir /srv/zulip-emoji-cache
sudo chown -R `whoami`:`whoami` /srv/zulip-emoji-cache
./tools/setup/emoji/build_emoji
./tools/inline-email-css
./tools/setup/build_pygments_data
./tools/setup/generate_zulip_bots_static_files
./scripts/setup/generate_secrets.py --development
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
```

To start the development server:

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

… and visit <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 yarn proxy and https-proxy using:
 ```
 yarn config set proxy http://proxy_host:port
 yarn config set https-proxy http://proxy_host:port
 ```

## Using Docker (experimental)

Start by [cloning your fork of the zulip repository](../contributing/git-guide.html#step-1b-clone-to-your-machine):

`git clone --config pull.rebase https://github.com/YOURUSERNAME/zulip.git`

The docker instructions for development are experimental, so they may
have bugs.  If you try them and run into any issues, please report
them!

You can also use Docker to run a Zulip development environment.
First, you need to install Docker in your development machine
following the [instructions][docker-install].  Some other interesting
links for somebody new in Docker are:

* [Get Started](https://docs.docker.com/engine/installation/linux/)
* [Understand the architecture](https://docs.docker.com/engine/understanding-docker/)
* [Docker run reference](https://docs.docker.com/engine/reference/run/)
* [Dockerfile reference](https://docs.docker.com/engine/reference/builder/)

[docker-install]: https://docs.docker.com/engine/installation/

Then you should create the Docker image based on Ubuntu Linux, first
go to the directory with the Zulip source code:

```
docker build -t user/zulipdev -f Dockerfile-dev .
```


Commit and tag the provisioned images. The below will install Zulip's dependencies:
```
docker run -itv $(pwd):/srv/zulip -p 9991:9991 user/zulipdev /bin/bash
$ /bin/bash sudo chown -R zulip:zulip /srv/zulip
$ /bin/bash /srv/zulip/tools/provision --docker
docker ps -af ancestor=user/zulipdev
docker commit -m "Zulip installed" <container id> user/zulipdev:v2
```

Now you can run the docker server with:

```
docker run -itv $(pwd):/srv/zulip -p 9991:9991 user/zulipdev:v2 \
    /srv/zulip/tools/start-dockers
```

You'll want to
[read the guide for Zulip development](../development/setup-vagrant.html#step-4-developing)
to understand how to use the Zulip development.  Note that
`start-dockers` automatically runs `tools/run-dev.py` inside the
container; you can then visit http://localhost:9991 to connect to your
new Zulip Docker container.


To view the container's `run-dev.py` console logs to get important
debugging information (and e.g. outgoing emails) printed by the Zulip
development environment, you can use:
```
docker logs --follow <container id>
```

To restart the server use:
```
docker ps
docker restart <container id>
```

To stop the server use:
```
docker ps
docker kill <container id>
```

If you want to connect to the Docker instance to run commands
(e.g. build a release tarball), you can use:

```
docker ps
docker exec -it <container id> /bin/bash
$ source /home/zulip/.bash_profile
$ <Your commands>
$ exit
```

If you want to run all the tests you need to start the servers first,
you can do it with:

```
docker run -itv $(pwd):/srv/zulip user/zulipdev:v2 /bin/bash
$ tools/test-all-docker
```

You can modify the source code in your development machine and review
the results in your browser.


Currently, the Docker workflow is substantially less convenient than
the Vagrant workflow and less documented; please contribute to this
guide and the Docker tooling if you are using Docker to develop Zulip!
