The [Discourse Docker Image][dd] makes it easy to set up Discourse on a cloud server. We will use [Digital Ocean][do], although these steps will work on other similar services.

This guide assumes that you have no knowledge of Ruby/Rails or Linux shell. Feel free to skip steps you are comfortable with.

# Create New Digital Ocean Droplet
|
|
|
|
Discourse requires a minimum of 1 GB RAM, and 2 GB RAM is recommended. We'll use "discourse" as the Hostname.
|
|
|

|
|
|
|
Install Discourse on Ubuntu 12.04.3 LTS x64. We always recommend using [the current LTS distribution][lts].
|
|
|
|
<img src="https://meta-discourse.r.worldssl.net/uploads/default/3399/f3fc67ee6aa90ea4.png" width="690" height="477">
|
|
|
|
You will receive a mail from Digital Ocean with the root password to your Droplet. (However, if you use SSH keys, you may not need a password to log in.)
|
|
|
|
# Access Your Droplet
|
|
|
|
Connect to your Droplet via SSH:
|
|
|
|
ssh root@192.168.1.1
|
|
|
|
(Alternately, use [Putty][put] on Windows)
|
|
|
|
Replace `192.168.1.1` with the IP address of your Droplet.

|
|
|
|
You will be asked for permission to connect, type `yes`, then the root password, which is in the email Digital Ocean sent you when the Droplet was set up. Enter it.

# Install Git
|
|
|
|
sudo apt-get install git
|
|
|
|

# Generate SSH Key
|
|
|
|
**We strongly recommend setting a SSH key because you may need to access the Rails console for debugging purposes. This <i>cannot</i> be done after bootstrapping the app.**
|
|
|
|
ssh-keygen -t rsa -C "your_email@example.com"
|
|
|
|
(We want the default settings, so when asked to enter a file in which to save the key, just press <kbd>enter</kbd>. Via [GitHub's SSH guide][ssh].)
|
|
|
|
# Install Docker
|
|
|
|
sudo apt-get update
|
|
sudo apt-get install linux-image-generic-lts-raring linux-headers-generic-lts-raring
|
|
|
|
<img src="https://meta-discourse.r.worldssl.net/uploads/default/3001/e94722e882f28994.png" width="566" height="339">
|
|
|
|
Reboot the server:
|
|
|
|
sudo reboot
|
|
|
|
<img src="https://meta-discourse.r.worldssl.net/uploads/default/3003/d3cc759ced335d25.png" width="532" height="155">
|
|
|
|
This will log you out from your SSH session, so reconnect:
|
|
|
|
ssh root@192.168.1.1
|
|
|
|
Finish installing Docker:
|
|
|
|
sudo wget -qO- https://get.docker.io/ | sh
|
|
|
|

# Install Discourse
|
|
|
|
Create a `/var/docker` folder where all the Docker related stuff will reside:
|
|
|
|
mkdir /var/docker
|
|
|
|
Clone the [Official Discourse Docker Image][dd] into this `/var/docker` folder:
|
|
|
|
git clone https://github.com/discourse/discourse_docker.git /var/docker
|
|
|
|
Switch to your Docker folder:
|
|
|
|
cd /var/docker
|
|
|
|
Copy the `samples/standalone.yml` file into the `containers` folder as `app.yml`, so the path becomes `containers/app.yml`:
|
|
|
|
cp samples/standalone.yml containers/app.yml
|
|
|
|
<img src="https://meta-discourse.r.worldssl.net/uploads/default/3005/5c253f4657e2133f.png" width="571" height="56">
|
|
|
|
Edit `app.yml`:
|
|
|
|
nano containers/app.yml
|
|
|
|
(We recommend Nano because it works like a typical GUI text editor, just use your arrow keys. Hit <kbd>Ctrl</kbd><kbd>O</kbd> then <kbd>Enter</kbd> to save and <kbd>Ctrl</kbd><kbd>X</kbd> to exit. However, feel free to choose whatever text editor you like. In the below screenshot we use Vim.)
|
|
|
|
<img src="https://meta-discourse.r.worldssl.net/uploads/default/3006/ed9f51b3a44f2b86.png" width="572" height="451">
|
|
|
|
Edit as desired, but at minimum set `DISCOURSE_DEVELOPER_EMAILS` and `DISCOURSE_HOSTNAME`.
|
|
|
|
<img src="https://meta-discourse.r.worldssl.net/uploads/default/2979/e6fedbde9b471880.png" width="565" height="172">
|
|
|
|
I renamed `DISCOURSE_HOSTNAME` to `discourse.techapj.com`, this means that I want to host my instance of Discourse on `http://discourse.techapj.com/`. You'll need to modify your DNS records to reflect the IP address and preferred URL address of your server.
|
|
|
|
# Mail Setup
|
|
|
|
**Email is critical to Discourse. We strongly recommend configuring mail settings before bootstrapping.**
|
|
|
|
- If you already have a mail server, put your existing mail server credentials in the `app.yml` file.
|
|
|
|
- Otherwise, create a free account on [**Mandrill**][man] (or [Mailgun][gun], or [Mailjet][jet]), and put your mail credentials (available via the Mandrill dashboard) in the `app.yml` file. The settings you want to change are `DISCOURSE_SMTP_ADDRESS`, `DISCOURSE_SMTP_PORT`, `DISCOURSE_SMTP_USER_NAME`, `DISCOURSE_SMTP_PASSWORD`.
|
|
|
|
# Add Your SSH Key
|
|
|
|
If you successfully generated the SSH key as described earlier, get it:
|
|
|
|
cat ~/.ssh/id_rsa.pub
|
|
|
|
Copy the entire output and paste it into the `ssh_key` setting in the `app.yml` file.
|
|
|
|
# Bootstrap Discourse
|
|
|
|
Be sure to save the `app.yml` file, and begin bootstrapping Discourse:
|
|
|
|
sudo ./launcher bootstrap app
|
|
|
|
<img src="https://meta-discourse.r.worldssl.net/uploads/default/3007/c0596ad3d330ae71.png" width="567" height="138">
|
|
|
|
This command may take some time, so be prepared to wait. It is automagically configuring your Discourse environment.
|
|
|
|
After that completes, start Discourse:
|
|
|
|
sudo ./launcher start app
|
|
|
|
<img src="https://meta-discourse.r.worldssl.net/uploads/default/3008/ced00cf4782f020c.png" width="568" height="137">
|
|
|
|
Congratulations! You now have your own instance of Discourse, accessible via the domain name you entered in `app.yml` earlier.
|
|
|
|
<img src="https://meta-discourse.r.worldssl.net/uploads/default/3397/ea8c3de3a4b7361d.png" width="690" height="207">
|
|
|
|
You can also access it by visiting the server IP address directly, e.g. `http://192.168.1.1`.
|
|
|
|
# Log In and Become Admin
|
|
|
|
Sign into your Discourse instance. If you configured `DISCOURSE_DEVELOPER_EMAILS` and your email matches, your account will be made Admin by default.
|
|
|
|
If your account was not made admin, try SSH'ing into your container (assuming you entered your SSH key in the `app.yml` file):
|
|
|
|
./launcher ssh my_container
|
|
sudo -iu discourse
|
|
cd /var/www/discourse
|
|
RAILS_ENV=production bundle exec rails c
|
|
u = User.last
|
|
u.admin = true
|
|
u.save
|
|
|
|
This will manually make the first user an admin.
