## Getting started
Getting started
-------------------
### Using Docker or Docker Compose
#### Using Docker
1. Create directories ```files``` and ```meta``` and run ```chown -R 65534:65534 meta && chown -R 65534:65534 files```
2. Create a config file (example provided in repo), we'll refer to it as __linx-server.conf__ in the following examples
1. Create a directory named `_data` and change its ownership `chown -R 65534:65534 _data` (`65534` is the `nobody` user & group).
2. Create a config file named `linx-server.conf` (check [linx-server.conf.example](linx-server.conf.example)) inside that `_data` directory.
#### Docker
Example running
```sh
docker run -p 8080:8080 -v ./_data/linx-server.conf:/data/linx-server.conf -v ./_data/meta:/data/meta -v ./_data/files:/data/files -v ./_data/custom_pages:/data/custom_pages ghcr.io/m-primo/linx-server:latest -config /data/linx-server.conf
```
docker run -p 8080:8080 -v /path/to/linx-server.conf:/data/linx-server.conf -v /path/to/meta:/data/meta -v /path/to/files:/data/files andreimarcu/linx-server -config /data/linx-server.conf
```
Example with docker-compose
#### Docker Compose
Check [compose.yml](compose.yml), update it and remove this block:
```yml
build:
context: .
```
version: '2.2'
services:
linx-server:
container_name: linx-server
image: andreimarcu/linx-server
command: -config /data/linx-server.conf
volumes:
- /path/to/files:/data/files
- /path/to/meta:/data/meta
- /path/to/linx-server.conf:/data/linx-server.conf
network_mode: bridge
ports:
- "8080:8080"
restart: unless-stopped
```
Ideally, you would use a reverse proxy such as nginx or caddy to handle TLS certificates.
#### Using a binary release
Then change the `image` value from `m-primo/linx-server:latest` to `ghcr.io/m-primo/linx-server:latest`.
1. Grab the latest binary from the [releases](https://github.com/andreimarcu/linx-server/releases), then run ```go install```
2. Run ```linx-server -config path/to/linx-server.conf```
### Using a binary release
Usage
-----
1. Download the latest binary from the [releases](https://github.com/m-primo/linx-server/releases).
2. Extract the archive `tar -xvzf linx-server.tar.gz`.
3. Run ```linx.sh -config /path/to/linx-server.conf```.
Ideally, you would use a reverse proxy such as Nginx, Caddy, or Apache to handle TLS certificates and act as a high performance web server.
## Usage
### Configuration
#### Configuration
All configuration options are accepted either as arguments or can be placed in a file as such (see example file linx-server.conf.example in repo):
```ini
bind = 127.0.0.1:8080
sitename = myLinx
maxsize = 4294967296
maxexpiry = 86400
# ... etc
```
...and then run ```linx-server -config path/to/linx-server.conf```
```

#### Cleaning up expired files
When files expire, access is disabled immediately, but the files and metadata

Deployment
----------
## Deployment
Linx-server supports being deployed in a subdirectory (ie. example.com/mylinx/) as well as on its own (example.com/).
#### 1. Using fastcgi
### 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:
```
```nginx
server {
...
server_name yourlinx.example.org;
...
client_max_body_size 4096M;
location / {
fastcgi_pass 127.0.0.1:8080;
include fastcgi_params;
}
...
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 = true``` 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.
And run linx-server with the `fastcgi = true` 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
#### 3. Using the built-in http server
Run linx-server normally.
Development
-----------
Any help is welcome, PRs will be reviewed and merged accordingly.
The official IRC channel is #linx on irc.oftc.net
## Development
1. ```go get -u github.com/andreimarcu/linx-server ```
2. ```cd $GOPATH/src/github.com/andreimarcu/linx-server ```
3. ```go build && ./linx-server```
Any help is welcome, PRs will be reviewed and merged accordingly.
```sh
git pull https://github.com/m-primo/linx-server.git
cp -r linx-server /go/src/github.com/andreimarcu/
cd /go/src/github.com/andreimarcu/linx-server/
go mod download
go build -o /go/bin/linx-server .
cp /go/bin/linx-server /usr/local/bin/linx-server
mkdir -p /data/files && mkdir -p /data/meta && mkdir -p /data/locks && mkdir -p /data/custom_pages && chown -R 65534:65534 /data
```
(You might want to adjust a command or two)
or using Docker.
```sh
git pull https://github.com/m-primo/linx-server.git
docker compose build --no-cache
docker compose up -d
```
It's better to use Docker Compose for both development and deployment, since this is my method of contributing to this project.
