# Change It
|
|
|
|
|
|
|
|
|
|
Please note, the following instructions have only been tested on the Debian Stretch OS.
|
|
|
|
|
|
|
|
|
|
You'll need to run an [RQLite] database first:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
$ apt update && apt install -y make
|
|
|
|
|
$ make install-rqlite
|
|
|
|
|
$ make rqlited
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Then get [Pipenv] and run the development server with:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
$ pipenv install --dev --three
|
|
|
|
|
$ pipenv run devserver
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
If you need to check the database contents, run:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
$ make rqlite
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
And then run `.help` for which commands are available.

# Test It
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
$ pipenv run tox
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Refer to the [tox.ini](tox.ini) for configuration options.

# Deploy It
|
|
|
|
|
|
|
|
|
|
See [ansible/README.md](ansible/README.md) for this.

# Maintain It
|
|
|
|
|
|
|
|
|
|
The XPPL is made up of a few parts:
|
|
|
|
|
|
|
|
|
|
* The [Flask] application and it's dependencies.
|
|
|
|
|
* The [RQLite] database.
|
|
|
|
|
* The [Syncthing] integration for uploads.
|
|
|
|
|
* The Nginx reverse proxy.
|
|
|
|
|
* The Let's Encrypt web certificates.
|
|
|
|
|
|
|
|
|
|
If you know [Ansible] (it's just YAML), you can just [read the entire configuration].
|
|
|
|
|
|
|
|
|
|
On the varia.zone machine, you can check the running services with:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
$ sudo supervisorctl status all # check all services
|
|
|
|
|
$ sudo supervisorctl stop xppl:* # stop all XPPL services
|
|
|
|
|
$ sudo supervisorctl start xppl:* # start all XPPL services
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
You can also view the error logs with:
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
$ sudo supervisorctl tail xppl:xppl-flask stderr
|
|
|
|
|
$ sudo supervisorctl tail xppl:xppl-rqlite stderr
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
The `/var/xppl/xppl/uploads` folder is managed by the Varia [Syncthing UI].
|
|
|
|
|
|
|
|
|
|
The RQLite database is located at `/var/xppl/rqlite/node.1`. No cluster is configured.
|
|
|
|
|
|
|
|
|
|
No backups are configured right now.
