**Set up Discourse on a cloud server in under 30 minutes** with zero knowledge of Ruby, Rails or Linux shell using our [Discourse Docker image][dd]. We prefer [Digital Ocean][do], although these steps may work on other cloud providers that also support Docker. Let's begin!
|
|
|
|
# Create New Digital Ocean Droplet
|
|
|
|
[Sign up for Digital Ocean][do], update billing info, then begin creating your new cloud server (Droplet).
|
|
|
|
Use the URL of your new site as the Droplet hostname, e.g. `discourse.example.com`. Discourse requires a minimum of **1 GB RAM** for small communities; we recommend 2 GB RAM for medium communities.
|
|
|
|
<img src="http://www.discourse.org/images/install/droplet-step-1.png" width="670" height="489">
|
|
|
|
Install Discourse on Ubuntu 14.04 LTS x64. Always select [the latest LTS distribution][lts].
|
|
|
|
<img src="http://www.discourse.org/images/install/droplet-step-2.png" width="540" height="478">
|
|
|
|
You will receive a mail from Digital Ocean with the root password to your Droplet. (However, if you know [how to use SSH keys](https://www.google.com/search?q=digitalocean+ssh+keys), you may not need a password to log in.)
|
|
|
|
# Access Your Droplet
|
|
|
|
Connect to your Droplet via SSH, or use [Putty][put] on Windows:
|
|
|
|
ssh root@192.168.1.1
|
|
|
|
Replace `192.168.1.1` with the IP address of your Droplet.
|
|
|
|
<img src="http://www.discourse.org/images/install/ssh-login-start.png" width="586" height="128">
|
|
|
|
You will be asked for permission to connect, type `yes`, then enter the root password from the email Digital Ocean sent you when the Droplet was set up. You may be prompted to change the root password, too.
|
|

|
|
|
|
# Set up Swap (if needed)
|
|
|
|
- If you're using the minimum 1 GB install, you *must* [set up a swap file](https://meta.discourse.org/t/create-a-swapfile-for-your-linux-server/13880).
|
|
|
|
- If you're using 2 GB+ memory, you can probably get by without a swap file.
|
|
|
|
# Install Git
|
|
|
|
apt-get install git
|
|
|
|
<img src="http://www.discourse.org/images/install/install-git.png" width="586" height="293">
|
|
|
|
# Install Docker
|
|
|
|
wget -qO- https://get.docker.io/ | sh
|
|
|
|
<img src="http://www.discourse.org/images/install/wget-docker.png" width="586" height="452">
|
|
|
|
# Install Discourse
|
|
|
|
Create a `/var/discourse` folder, clone the [Official Discourse Docker Image][dd] into it, and make a copy of the config file as `app.yml`:
|
|
|
|
mkdir /var/discourse
|
|
git clone https://github.com/discourse/discourse_docker.git /var/discourse
|
|
cd /var/discourse
|
|
cp samples/standalone.yml containers/app.yml
|
|
|
|
<img src="https://meta.discourse.org/uploads/default/33557/28f36eb5069e75c4.png" width="662" height="240">
|
|
|
|
# Edit Discourse Configuration
|
|
|
|
Edit the Discourse configuration at `app.yml`:
|
|
|
|
nano containers/app.yml
|
|
|
|
We recommend Nano because it works like a typical GUI text editor, just use your arrow keys.
|
|
|
|
- Set `DISCOURSE_DEVELOPER_EMAILS` to your email address.
|
|
|
|
- Set `DISCOURSE_HOSTNAME` to `discourse.example.com`, this means you want your Discourse available at `http://discourse.example.com/`. You'll need to update the DNS A record for this domain with the IP address of your server.
|
|
|
|
- Place your mail credentials in `DISCOURSE_SMTP_ADDRESS`, `DISCOURSE_SMTP_PORT`, `DISCOURSE_SMTP_USER_NAME`, `DISCOURSE_SMTP_PASSWORD`. Be sure you remove the comment `#` character and space from the front of these lines as necessary.
|
|
|
|
- If you are using a 1 GB instance, set `UNICORN_WORKERS` to 2 and `db_shared_buffers` to 128MB so you have more memory room.
|

# Email Is Important
|
|
|
|
**Email is CRITICAL for account creation and notifications in Discourse. If you do not properly configure email before bootstrapping YOU WILL HAVE A BROKEN SITE!**
|
|
|
|
- Already have a mail server? Great. Use your existing mail server credentials.
|
|
|
|
- No existing mail server, or you don't know what it is? No problem, create a free account on [**Mandrill**][man] (or [Mailgun][gun], or [Mailjet][jet]), and use the credentials provided in the dashboard.
|
|
|
|
- For proper email deliverability, you must set the [SPF and DKIM records](http://help.mandrill.com/entries/21751322-What-are-SPF-and-DKIM-and-do-I-need-to-set-them-up-) in your DNS. In Mandrill, that's under Sending Domains, View DKIM/SPF setup instructions.
|
|
|
|
# Bootstrap Discourse
|
|
|
|
Save the `app.yml` file, and begin bootstrapping Discourse:
|
|
|
|
./launcher bootstrap app
|
|
|
|
This command takes about 8 minutes. It is automagically configuring your Discourse environment.
|
|
|
|
After that completes, start Discourse:
|
|
|
|
./launcher start app
|
|
|
|
<img src="https://meta.discourse.org/uploads/default/33558/a988b9ec9ac5ff7a.png" width="669" height="233">
|
|
|
|
Congratulations! You now have your own instance of Discourse!
|
|
|
|
It should be accessible via the domain name `discourse.example.com` you entered earlier, provided you configured DNS. If not, you can also visit the server IP directly, e.g. `http://192.168.1.1`.

# Register New Account and Become Admin
|
|
|
|
There is a reminder at the top about `DISCOURSE_DEVELOPER_EMAILS`; register a new account via one of those email addresses, and your account will automatically be made an Admin.
|
|
|
|
(If you *don't* get any email from your install, and are unable to register a new admin account, please see our [Email Troubleshooting checklist](https://meta.discourse.org/t/troubleshooting-email-on-a-new-discourse-install/16326).)
|
|
|
|
<img src="http://www.discourse.org/images/install/discourse-installed.png" width="690" height="350">
|
|
|
|
You should see Staff topics and the [Admin Quick Start Guide](https://github.com/discourse/discourse/blob/master/docs/ADMIN-QUICK-START-GUIDE.md). It contains the next steps for further configuring and customizing your Discourse install.
|
|
|
|
(If you are still unable to register a new admin account via email, see [Create Admin Account from Console](https://meta.discourse.org/t/create-admin-account-from-console/17274), but please note that *you will have a broken site* unless you get email working on your instance.)
|
|
|
|
|
|
# Post-Install Maintenance
|
|
|
|
To **upgrade Discourse to the latest version**, visit `/admin/upgrade` and follow the instructions.
|
|
|
|
The `launcher` command in the `/var/discourse` folder can be used for various kinds of maintenance:
|
|
|
|
```
|
|
Usage: launcher COMMAND CONFIG [--skip-prereqs]
|
|
Commands:
|
|
start: Start/initialize a container
|
|
stop: Stop a running container
