## Installation
|
|
|
|
### Requirements
|
|
|
|
[Node.js](https://nodejs.org/) >= **12.17.0**.
|
|
|
|
### GNU/Linux and other UNIX-like systems
|
|
|
|
#### Quick install on Debian/Ubuntu
|
|
|
|
```sh
|
|
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
|
|
sudo apt install -y nodejs
|
|
git clone --branch master https://github.com/ether/etherpad-lite.git &&
|
|
cd etherpad-lite &&
|
|
src/bin/run.sh
|
|
```
|
|
|
|
#### Manual install
|
|
|
|
You'll need Git and [Node.js](https://nodejs.org/) installed.
|
|
|
|
**As any user (we recommend creating a separate user called etherpad):**
|
|
|
|
1. Move to a folder where you want to install Etherpad.
|
|
2. Clone the Git repository: `git clone --branch master
|
|
https://github.com/ether/etherpad-lite.git`
|
|
3. Change into the new directory containing the cloned source code: `cd
|
|
etherpad-lite`
|
|
4. Run `src/bin/run.sh` and open http://127.0.0.1:9001 in your browser.
|
|
|
|
To update to the latest released version, execute `git pull origin`. The next
|
|
start with `src/bin/run.sh` will update the dependencies.
|
|
|
|
### Windows
|
|
|
|
#### Prebuilt Windows package
|
|
|
|
This package runs on any Windows machine. You can perform a manual installation
|
|
via git for development purposes, but as this uses symlinks which performs
|
|
unreliably on Windows, please stick to the prebuilt package if possible.
|
|
|
|
1. [Download the latest Windows package](https://etherpad.org/#download)
|
|
2. Extract the folder
|
|
|
|
Run `start.bat` and open <http://localhost:9001> in your browser.
|
|
|
|
#### Manually install on Windows
|
|
|
|
You'll need [Node.js](https://nodejs.org) and (optionally, though recommended)
|
|
git.
|
|
|
|
1. Grab the source, either:
|
|
* download <https://github.com/ether/etherpad-lite/zipball/master>
|
|
* or `git clone --branch master
|
|
https://github.com/ether/etherpad-lite.git`
|
|
2. With a "Run as administrator" command prompt execute
|
|
`src\bin\installOnWindows.bat`
|
|
|
|
Now, run `start.bat` and open http://localhost:9001 in your browser.
|
|
|
|
Update to the latest version with `git pull origin`, then run
|
|
`src\bin\installOnWindows.bat`, again.
|
|
|
|
If cloning to a subdirectory within another project, you may need to do the
|
|
following:
|
|
|
|
1. Start the server manually (e.g. `node src/node/server.js`)
|
|
2. Edit the db `filename` in `settings.json` to the relative directory with
|
|
the file (e.g. `application/lib/etherpad-lite/var/dirty.db`)
|
|
3. Add auto-generated files to the main project `.gitignore`
|
|
|
|
### Docker container
|
|
|
|
Find [here](doc/docker.md) information on running Etherpad in a container.
|
|
|
|
## Plugins
|
|
|
|
Etherpad is very customizable through plugins.
|
|
|
|
|
|
|
|
|
|
|
|
### Available Plugins
|
|
|
|
For a list of available plugins, see the [plugins
|
|
site](https://static.etherpad.org).
|
|
|
|
### Plugin Installation
|
|
|
|
You can install plugins from the admin web interface (e.g.,
|
|
http://127.0.0.1:9001/admin/plugins).
|
|
|
|
Alternatively, you can install plugins from the command line:
|
|
|
|
```sh
|
|
cd /path/to/etherpad-lite
|
|
# The `--no-save` and `--legacy-peer-deps` arguments are necessary to work
|
|
# around npm quirks.
|
|
npm install --no-save --legacy-peer-deps ep_${plugin_name}
|
|
```
|
|
|
|
Also see [the plugin wiki
|
|
article](https://github.com/ether/etherpad-lite/wiki/Available-Plugins).
|
|
|
|
### Suggested Plugins
|
|
|
|
Run the following command in your Etherpad folder to get all of the features
|
|
visible in the above demo gif:
|
|
|
|
```sh
|
|
npm install --no-save --legacy-peer-deps \
|
|
ep_align \
|
|
ep_comments_page \
|
|
ep_embedded_hyperlinks2 \
|
|
ep_font_color \
|
|
ep_headings2 \
|
|
ep_markdown \
|
|
ep_webrtc
|
|
```
|
|
|
|
For user authentication, you are encouraged to run an [OpenID
|
|
Connect](https://openid.net/connect/) identity provider (OP) and install the
|
|
following plugins:
|
|
|
|
* [ep_openid_connect](https://github.com/ether/ep_openid_connect#readme) to
|
|
authenticate against your OP.
|
|
* [ep_guest](https://github.com/ether/ep_guest#readme) to create a
|
|
"guest" account that has limited access (e.g., read-only access).
|
|
* [ep_user_displayname](https://github.com/ether/ep_user_displayname#readme)
|
|
to automatically populate each user's displayed name from your OP.
|
|
* [ep_stable_authorid](https://github.com/ether/ep_stable_authorid#readme) so
|
|
that each user's chosen color, display name, comment ownership, etc. is
|
|
strongly linked to their account.
|
|
|
|
## Next Steps
|
|
|
|
### Tweak the settings
|
|
|
|
You can modify the settings in `settings.json`. If you need to handle multiple
|
|
settings files, you can pass the path to a settings file to `src/bin/run.sh`
|
|
using the `-s|--settings` option: this allows you to run multiple Etherpad
|
|
instances from the same installation. Similarly, `--credentials` can be used to
|
|
give a settings override file, `--apikey` to give a different APIKEY.txt file
|
|
and `--sessionkey` to give a non-default `SESSIONKEY.txt`. **Each configuration
|
|
parameter can also be set via an environment variable**, using the syntax
|
|
`"${ENV_VAR}"` or `"${ENV_VAR:default_value}"`. For details, refer to
|
|
`settings.json.template`. Once you have access to your `/admin` section,
|
|
settings can be modified through the web browser.
|
|
|
|
If you are planning to use Etherpad in a production environment, you should use
|
|
a dedicated database such as `mysql`, since the `dirtyDB` database driver is
|
|
only for testing and/or development purposes.
|
|
|
|
### Secure your installation
|
|
|
|
If you have enabled authentication in `users` section in `settings.json`, it is
|
|
a good security practice to **store hashes instead of plain text passwords** in
|
|
that file. This is _especially_ advised if you are running a production
|
|
installation.
|
|
|
|
Please install [ep_hash_auth plugin](https://www.npmjs.com/package/ep_hash_auth)
|
|
and configure it. If you prefer, `ep_hash_auth` also gives you the option of
|
|
storing the users in a custom directory in the file system, without having to
|
|
edit `settings.json` and restart Etherpad each time.
|
|
|
|
### Customize the style with skin variants
|
|
|
|
Open http://127.0.0.1:9001/p/test#skinvariantsbuilder in your browser and start
|
|
playing!

## Helpful resources
|
|
|
|
The [wiki](https://github.com/ether/etherpad-lite/wiki) is your one-stop
|
|
resource for Tutorials and How-to's.
|
|
|
|
Documentation can be found in `doc/`.
|
|
|
|
## Development
|
|
|
|
### Things you should know
|
|
|
|
You can debug Etherpad using `src/bin/debugRun.sh`.
|
|
|
|
You can run Etherpad quickly launching `src/bin/fastRun.sh`. It's convenient for
|
|
developers and advanced users. Be aware that it will skip the dependencies
|
|
update, so remember to run `src/bin/installDeps.sh` after installing a new
|
|
dependency or upgrading version.
|
|
|
|
If you want to find out how Etherpad's `Easysync` works (the library that makes
|
|
it really realtime), start with this
|
|
[PDF](https://github.com/ether/etherpad-lite/raw/master/doc/easysync/easysync-full-description.pdf)
|
|
(complex, but worth reading).

### Contributing
|
|
|
|
Read our [**Developer
|
|
Guidelines**](https://github.com/ether/etherpad-lite/blob/master/CONTRIBUTING.md)
|
|
|
|
### HTTP API
|
|
|
|
Etherpad is designed to be easily embeddable and provides a [HTTP
|
|
API](https://github.com/ether/etherpad-lite/wiki/HTTP-API) that allows your web
|
|
application to manage pads, users and groups. It is recommended to use the
|
|
[available client
|
|
implementations](https://github.com/ether/etherpad-lite/wiki/HTTP-API-client-libraries)
|
|
in order to interact with this API.
|
|
|
|
OpenAPI (previously swagger) definitions for the API are exposed under
|
|
`/api/openapi.json`.
|
|
|
|
### jQuery plugin
|
|
|
|
There is a [jQuery plugin](https://github.com/ether/etherpad-lite-jquery-plugin)
|
|
that helps you to embed Pads into your website.
|
|
|
|
### Plugin Framework
|
|
|
|
Etherpad offers a plugin framework, allowing you to easily add your own
|
|
features. By default your Etherpad is extremely light-weight and it's up to you
|
|
to customize your experience. Once you have Etherpad installed you should [visit
|
|
the plugin page](https://static.etherpad.org/) and take control.
|
|
|
|

|
|
[TranslateWiki](https://translatewiki.net/).
