## Running
|
|
|
|
The nats-server has many command line options. To get started, you don't have to specify anything.
|
|
In the absence of any flags, the NATS server will start listening for NATS client connections on port 4222.
|
|
By default, security is not enabled.
|
|
|
|
### Standalone
|
|
|
|
When the server starts it will print some information including where the server is listening for client connections:
|
|
|
|
```
|
|
> nats-server
