|
|
|
|
#### Options
|
|
- ```-bind 127.0.0.1:8080``` -- what to bind to (default is 127.0.0.1:8080)
|

- ```-sitename myLinx``` -- the site name displayed on top (default is inferred from Host header)
|
|

|
|
|
|
#### Storage backends
|
|
The following storage backends are available:
|
|
|
|
|Name|Options|Notes
|
|
|----|-------|-----
|
|
|LocalFS|```-filespath files/``` -- Path to store uploads (default is files/)<br />```-metapath meta/``` -- Path to store information about uploads (default is meta/)|Enabled by default, this backend uses the filesystem|
|
|
|S3|```-s3-endpoint https://...``` -- S3 endpoint<br>```-s3-region us-east-1``` -- S3 region<br>```-s3-bucket mybucket``` -- S3 bucket to use for files and metadata<br>```-s3-use-path-style``` -- force path-style addresing (e.g. https://s3.amazonaws.com/linx/example.txt)<br><br>Environment variables to provide:<br>```AWS_ACCESS_KEY_ID``` -- the S3 access key<br>```AWS_SECRET_ACCESS_KEY ``` -- the S3 secret key<br>```AWS_SESSION_TOKEN``` (optional) -- the S3 session token|Use with any S3-compatible provider.<br> This implementation will stream files through the linx instance (every download will request and stream the file from the S3 bucket).<br><br>For high-traffic environments, one might consider using an external caching layer such as described [in this article](https://blog.sentry.io/2017/03/01/dodging-s3-downtime-with-nginx-and-haproxy.html).|
|
|
|
|
|
|
#### SSL with built-in server
|
|
- ```-certfile path/to/your.crt``` -- Path to the ssl certificate (required if you want to use the https server)
|
|
- ```-keyfile path/to/your.key``` -- Path to the ssl key (required if you want to use the https server)
|
|
|
|
#### Use with http proxy
|
|
- ```-realip``` -- let linx-server know you (nginx, etc) are providing the X-Real-IP and/or X-Forwarded-For headers.
|
|
|
|
#### Use with fastcgi
|
|
- ```-fastcgi``` -- serve through fastcgi
|
|
|
|
#### Require API Keys for uploads
|
|
- ```-authfile path/to/authfile``` -- (optionally) require authorization for upload/delete by providing a newline-separated file of scrypted auth keys
|
|
- ```-remoteauthfile path/to/remoteauthfile``` -- (optionally) require authorization for remote uploads by providing a newline-separated file of scrypted auth keys
|
|
|
|
A helper utility ```linx-genkey``` is provided which hashes keys to the format required in the auth files.
|
|
|
|
|
|
Cleaning up expired files
|
|
-------------------------
|
|
When files expire, access is disabled immediately, but the files and metadata
|
|
will persist on disk until someone attempts to access them. If you'd like to
|
|
automatically clean up files that have expired, you can use the included
|
|
`linx-cleanup` utility. To run it automatically, use a cronjob or similar type
|
|
of scheduled task.
|
|
|
|
You should be careful to ensure that only one instance of `linx-client` runs at
|
|
a time to avoid unexpected behavior. It does not implement any type of locking.
|
|
|
|
#### Options
|
|
- ```-filespath files/``` -- Path to stored uploads (default is files/)
|
|
- ```-metapath meta/``` -- Path to stored information about uploads (default is meta/)
|
|
- ```-nologs``` -- (optionally) disable deletion logs in stdout
|
|
|
|
|
|
Deployment
|
|
----------
|
|
Linx-server supports being deployed in a subdirectory (ie. example.com/mylinx/) as well as on its own (example.com/).
|
|
|
|
|
|
#### 1. Using fastcgi
|
|
|
|
A suggested deployment is running nginx in front of linx-server serving through fastcgi.
|
|
This allows you to have nginx handle the TLS termination for example.
|
|
An example configuration:
|
|
```
|
|
server {
|
|
...
|
|
server_name yourlinx.example.org;
|
|
...
|
|
|
|
client_max_body_size 4096M;
|
|
location / {
|
|
fastcgi_pass 127.0.0.1:8080;
|
|
include fastcgi_params;
|
|
}
|
|
}
|
|
```
|
|
And run linx-server with the ```-fastcgi``` option.
|
|
|
|
#### 2. Using the built-in https server
|
|
Run linx-server with the ```-certfile path/to/cert.file``` and ```-keyfile path/to/key.file``` options.
|
|
|
|
#### 3. Using the built-in http server
|
|
Run linx-server normally.
|
|
|
|
#### 4. Using Docker with the built-in http server
|
|
First, build the image:
|
|
```docker build -t linx-server .```
|
|
|
|
You'll need some directories for the persistent storage. For the purposes of this example, we will use `/media/meta` and `/media/files`.
|
|
|
|
Then, run it:
|
|
```docker run -p 8080:8080 -v /media/meta:/data/meta -v /media/files:/data/files linx-server```
|
|
|
|
|
|
