Let's rock the Raspberry Pi

#### 1. set wifi
```
sudo vi etc/wpa_supplicant/wpa_supplicant.conf
```

```
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="wifi_name"
    psk="password"
}
```


#### 2. set ssh
create a file in `boot` in SD card

```
cd /boot
touch ssh
```


#### 3. allow root login
```
sudo vi etc/ssh/sshd_config
```

Change `PermitRootLogin prohibit-password` to `PermitRootLogin yes`



#### 4. login

```
ssh pi@ip_address
```

default password is `raspberry`



#### 5. change root password

```
sudo su
passwd root
```



#### 6. reboot then using ssh

```
ssh root@ip_address
```

you can also using `ssh-copy-id root@ip_address` to use your key



#### 7. mount external disk (only for EXT4 format)

check info about disks: `sudo fdisk -l`

check uuid about disks: `sudo blkid`

```
mkdir /media/usb
vi /etc/fstab
```

```

UUID=fee4308e-1c45-4229-a526-41f43b85928b /media/usb ext4 defaults,auto,users,rw,nofail,x-systemd.device-timeout=30 0 0

```


#### 8. reboot and enjoy!
