## Launch
|
|
|
|
|
|
|
|
|
|
### Start
|
|
|
|
|
|
|
|
|
|
Create as many servers as wanted by providing different `type`, `host`, `port` and other arguments.
|
|
|
|
|
|
|
|
|
|
* for security reasons, `next` server prevents any access to the hidden files (started with dot).\
|
|
|
|
|
* also, clients can't access any data out the `root` path, defined on server startup
|
|
|
|
|
|
|
|
|
|
Simple example:
|
|
|
|
|
|
|
|

|
php src/server.php type=nex host=127.0.0.1 port=1900 root=/target/dir

|
