Get release and run
-------------------
1. Grab the latest binary from the [releases](https://github.com/andreimarcu/linx-server/releases)
2. Run ```./linx-server...```

  
Usage
-----

#### Configuration
All configuration options are accepted either as arguments or can be placed in an ini-style file as such:  
```ini
sitename = "my linx"  
siteurl = "https://linx.example.com"  
remoteuploads = true
# etc
```  
...and then invoke ```linx-server -config path/to/config.ini```  

#### Common 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 linx)
- ```-siteurl "http://mylinx.example.org/"``` -- the site url (for generating links)
- ```-filespath files/"``` -- Path to store uploads (default is files/)
- ```-metapath meta/``` -- Path to store information about uploads (default is meta/)
- ```-maxsize 4294967296``` -- maximum upload file size in bytes (default 4GB)
- ```-allowhotlink``` -- Allow file hotlinking
- ```-contentsecuritypolicy "..."``` -- Content-Security-Policy header for pages (default is "default-src 'self'; img-src 'self' data:; style-src 'self' 'unsafe-inline'; referrer origin;")
- ```-filecontentsecuritypolicy "..."``` -- Content-Security-Policy header for files (default is "default-src 'none'; img-src 'self'; object-src 'self'; media-src 'self'; referrer origin;")
- ```-xframeoptions "..." ``` -- X-Frame-Options header (default is "SAMEORIGIN")
- ```-remoteuploads``` -- (optionally) enable remote uploads (/upload?url=https://...) 
- ```-nologs``` -- (optionally) disable request logs in stdout

#### 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.


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.
