This will download and install everything needed to up and run Netdata.
Some users may not want to inject something directly into Bash without investigating it. If you don’t like this method, you can follow the steps below to install it on your system.
**On Arch Linux:**
The latest version is available in the Arch Linux default repositories. So, we can install it with [**pacman**][2] using command:
```
$ sudo pacman -S netdata
```
**On DEB and RPM-based systems**
NetData is not available in the default repositories of DEB based (Ubuntu / Debian) or RPM based (RHEL / CentOS / Fedora) systems. We need to install NetData manually from its Git repository.
To install Netdata on other Linux distributions, refer the [**official installation instructions page**][4].
##### Allow NetData default port via Firewall or Router
If your system stays behind any firewall or router, you must allow the default port **19999** to access the NetData web interface from any remote systems on the network,.
To enable and start Netdata service on systems that use **Systemd** , run:
```
$ sudo systemctl enable netdata
$ sudo systemctl start netdata
```
To stop:
```
$ sudo systemctl stop netdata
```
To enable and start Netdata service on systems that use **Init** , run:
```
$ sudo service netdata start
$ sudo chkconfig netdata on
```
To stop it:
```
$ sudo service netdata stop
```
### Access NetData via Web browser
