1-1. Install RaspberryPi OS Lite (32bit).

1-1-1.

Download Raspberry Pi Imager to your local PC
URL: https://www.raspberrypi.com/software/

1-1-2. Using Raspberry Pi OS 1.6.2 installer.

1-1-3.　 Change SSH and Wi-Fi settings before installation.

• Shift + Command + X ： open back menu mode

• Change Set hostname: from "raspberrypi.local" to "unvtportable.local".

• Enable SSH ☑ On.

• Set password for 'pi' user to "unvt".

• Configure Wi-Fi settings as appropriate for the work environment.

• Configure Locale as appropriate for the work environment.

• Configure the keyboard layout according to the language used.

• Save settings

1-1-4.　 Install OS on MicroSD card

If you cannot connect to ssh using the above steps

• Connect the SD card to your PC and place the file "ssh" directly under boot.

• If you create an ssh file with GUI, there is a bug that the created ssh file disappears on the second and subsequent ssh connections.We recommend that you create the ssh file in CUI using the following command.

cd /Volumes/boot  ## Move to boot
touch ssh ## Create ssh file
ls  ## Check for ssh files

If the error message WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

• If you have been through the process of re-installing the OS multiple times, you will probably get this error. This error seems to occur when reconfiguring the hostname with the same hostname that was previously set. If you get the above error, try the following command.

ssh-keygen -R "host name" ##In the above manual, unvtportable.local

1-2.　 Insert the installed MicroSD card into the RaspberryPi terminal and boot.

• Start a terminal and log in remotely via ssh.

% ssh [email protected]

• Password is set to unvt.

• It may take some time to make an ssh connection.

E: Sub-process /usr/bin/dpkg returned an error code (1)

The following command may solve the problem.

Temporarily move the debconf database:

sudo mv /var/cache/debconf /var/cache/debconf.bak

Create a new directory for the debconf database:

sudo mkdir /var/cache/debconf

Install apache2

sudo apt install -y apache2

Restore the debconf database:

sudo rm -r /var/cache/debconf
sudo mv /var/cache/debconf.bak /var/cache/debconf

1-3-4.　 hostapd and dnsmasq Installation

sudo apt install hostapd dnsmasq

1-3-5.　 DHCP settiong

sudo vi /etc/dnsmasq.conf

Copy and paste the following into the bottom line of the file.
Set the DHCP range from 192.168.10.11 to 192.168.10.200 so that 190 devices can be assigned IP addresses. You can change this range arbitrarily.

interface=wlan0
dhcp-range=192.168.10.11,192.168.10.200,255.255.255.0,12h

1-3-6. DHCP cliant settiong

Configure dhcpcd.conf to set a fixed IP address for the Raspberry Pi. In this case, we will use 192.168.10.10.

sudo vi /etc/dhcpcd.conf

Add the following settings.

interface wlan0
    static ip_address=192.168.10.10/24
    nohook wpa_supplicant

1-3-7. hostapd setting

Create a file in /etc/hostapd/hostapd.conf.

sudo touch /etc/hostapd/hostapd.conf

Copy and paste the following into the created hostapd.conf
SSID and password can be set freely. However, the password must be at least 8 characters long.

ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
interface=wlan0
driver=nl80211
country_code=JP
ssid=UNVTPortable
hw_mode=g
channel=11
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=unvtportable
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

After that, edit /etc/default/hostapd.

sudo vi /etc/default/hostapd

Change the DAEMON_CONF section as follows DAEMON_CONF="/etc/hostapd/hostapd.conf"

1-3-8 Unmasking hostapd

Execute the following commands.

sudo systemctl unmask hostapd.service

1-3-9 Start the service.

Execute the following commands.

sudo systemctl start hostapd.service

To start the hostapd service from raspberry pi startup, run the following command.

sudo systemctl enable hostapd.service

If you see "UNVT Portable" in the SSID list, you have succeeded!

1-4.　 FTP transfer of data you want to host

1-4-1.　 Change Permission on /var/www to 744

Access the Raspberry Pi via ssh and change the permissions after /var/www. If you do not change the permissions, you will not be able to access files from the outside.

pi@unvtportable:/var/www $ sudo chmod 744 -R .
pi@unvtportable:/var/www $ ls -al
total 12
drwxrwxrwx  3 root root 4096 Jan 15 10:16 .
drwxr-xr-x 12 root root 4096 Jan 15 10:16 ..
drwxrwxrwx  2 root root 4096 Jan 15 10:16 html

1-4-2. Download FTP client software

Cyberduck will be used in this case.
https://cyberduck.softonic.jp/mac

1-4-3.　 SFTP data transfer with Cyberduck

Launch Cyberduck and connect it to the Raspberry Pi. Set up as follows.
Connect to unvtportable.local via SFTP (port 22) using Cyberduck

• Connect to unvtportable.local
• Account: pi
• Password: unvt

1-5. Transfer hosting files to Raspberry Pi

Transfer the following folders and files under /var/www/html as they are.
File migration may take some time.
