★★★raspbian で　ルートを　USBハードディスクにする

すべてハードディスクで運用
です、　youtubeにも載ってますね

これは　前のraspbianではできたのですが、
stretchでは　何故か失敗。

従って　以下のでは上の図の如く

rootを　USBハードディスクにおいた。
micro SD はセルモーターのように起動に必要なだけとなった。

このUSBドライブは　容量が３２0Gあるので　raspberry pi 3は　立派なサーバーとなった。

たくさん書かれてますが、　rsync を利用した方法でやってみました。
https://www.raspberrypi.org/documentati ... des/msd.md
ここが出発点ですが　ちょっと不親切です。

1) raspbian を普通に　マイクロsd　で立ち上げます。

2) rewrite /boot/config.txt
dtoverlay=hifiberry-dacplus
dtparam=audio=on
program_usb_boot_mode=1

3) 再び　raspbian を普通に　マイクロsd　でたちあげ
そして次を確かめます
vcgencmd otp_dump | grep 17:

が
# > 17:3020000a
こうなってなうといけません
( たしかにこうなってたが　stretch では何かがかわったのか
　USB　HDDのみの運用は　結果的にはだめで
スターターとしての　マイクロSDカードが要った　）　

4)この後　 raspbian　をシャットダウンし　マイクロsdを抜き取ります。

-------------------------

5) 以下　 archlinuxの PC　に
マイクロSDカードと　USBハードディスクをつけます

まず　raspbian のマイクロSD（/dev/sdc）のブートローダ部分を
HDD（/dev/sdd）に　コピーするため

dd if=/dev/sdc of=/dev/sdd bs=512 count=16000
します

6)いま
マイクロsd は　以下です
fdisk -l /dev/sdc
Disk /dev/sdc: 15 GiB, 16088301568 bytes, 31422464 sectors
Device Boot Start End Sectors Size Id Type
/dev/sdc1 8192 93596 85405 41.7M c W95 FAT32 (LBA)
/dev/sdc2 94208 27277311 27183104 13G 83 Linux

さて　USB ハードディスクをを次のようにします。
1 8192 1056767 512.0 MiB 0700 Microsoft basic data
2 5252000 125542366 57.4 GiB 8300 Linux filesystem
3 1056800 5251071 2.0 GiB 8200 Linux swap

mkfs.vfat /dev/sdd1
mkfs.ext4 /dev/sdd2
mkswap /dev/sdd3

6)
mount /dev/sdc1 /mc1
mount /dev/sdc2 /mc2

mount /dev/sdd1 /md1
mount /dev/sdd2 /md2

rsync -avHx /mc1/ /md1/
rsync -avHx /mc2/ /md2/

別法

(cd /mc2;tar cvpf - . ) | (cd /md2 ; tar xpf - )

7)ファイルを３つ書き換えます
cp /md1/cmdline.txt /md1/cmdline.txt-ori
/md1/cmdline.txt
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/sda2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet splash plymouth.ignore-serial-consoles

/md2/etc/fstab
proc /proc proc defaults 0 0
/dev/sda1 /boot vfat defaults 0 2
/dev/sda2 / ext4 defaults,noatime 0 1
/dev/sda2 none swap defaults 0 0

/md2/etc/rc.local
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
printf "My IP address is %s\n" "$_IP"
fi
sleep 30
service dphys-swapfile stop
exit 0

8) umount /md1 /md2 /mc1 /mc2

9)こうしておいてから　USBハードディスクだけをRpi3にくっつけて電源をいれると
たちあがります。 

PS)
なお　元のSDのみの運用に戻す時は
cp /md1/cmdline.txt-ori　 /md1/cmdline.txt
です

以下は現在の状態です

/etc/rc.local

_IP=$(hostname -I) || true
if [ "$_IP" ]; then
printf "My IP address is %s\n" "$_IP"
fi
sleep 30
service dphys-swapfile stop
/home/pi/sshd+swapon.bat
exit 0

/home/pi/sshd+swapon.bat
swapon /dev/sda3
/etc/init.d/ssh restart

/etc/fstab
proc /proc proc defaults 0 0
/dev/sda1 /boot vfat defaults 0 2
/dev/sda2 / ext4 defaults,noatime 0 1
/dev/sda2 none swap defaults 0 0

/boot/config.txt
dtoverlay=hifiberry-dacplus
dtparam=audio=on

/boot/cmdline.txt
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/sda2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet splash plymouth.ignore-serial-consoles

/etc/rc.local

_IP=$(hostname -I) || true

if [ "$_IP" ]; then

printf "My IP address is %s\n" "$_IP"

sleep 30

service dphys-swapfile stop

exit 0

raspberry pi 3 で　hostapd + dnsmasq で　wifi アクセスポイントをつくる

wifi access point をつくる

なイメージです。

英語の
https://frillip.com/using-your-raspberry-pi-3-as-a-wifi-access-point-with-hostapd/
のとおり

最終のスクリプトは
./wifi-accessPoint.bat
sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT

service hostapd start
service dnsmasq start

必要な道具を用意します
aptitude install hostapd dnsmasq

/etc/dhcpcd.conf
hostname
clientid
persistent
option rapid_commit
option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes
option ntp_servers
require dhcp_server_identifier
slaac private
nohook lookup-hostname
denyinterfaces wlan0

ヘリポートにアドレスをふります
/etc/network/interfaces

source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback
iface eth0 inet manual
allow-hotplug wlan0
iface wlan0 inet static
address 172.24.1.1
netmask 255.255.255.0
network 172.24.1.0
broadcast 172.24.1.255

ヘリコプターがつける準備です
/etc/hostapd/hostapd.conf

interface=wlan0
driver=nl80211
ssid=Pi3-AP
hw_mode=g
channel=6
ieee80211n=1
wmm_enabled=1
ht_capab=[HT40][SHORT-GI-20][DSSS_CCK-40]
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_passphrase=1122334455

rsn_pairwise=CCMP

切符がないと　新幹線にはのれませんので
/etc/dnsmasq.conf
interface=wlan0 # Use interface wlan0
listen-address=172.24.1.1 # Explicitly specify the address to listen on
bind-interfaces # Bind to the interface to make sure we aren't sending things elsewhere
server=8.8.8.8 # Forward DNS requests to Google DNS
domain-needed # Don't forward short names
bogus-priv
dhcp-range=172.24.1.50,172.24.1.55,12h

これにて　
wifi いう電波に乗って　ヘリポートにおりたち（hostapdの役割）

dnsmasqから　切符をもらい

iptables によって新幹線にいけます

感謝です
日本語のサイトはいろいろ試しましたが駄目でした。
isc-dhcp サーバーは危なすぎます

raspbianでハイレゾを演奏する（volumio からでないよー）

a)　swapを大きくする編
http://inaba.hatenablog.com/entry/2016/12/13/023251を参考にして

SWAPが少なすぎるし　かつ　マイクロSDメモリでは　これがこわれちゃうので
（マイクロSDメモリには　システムがはいってる）
SWAPを本体から　分離する

cat /etc/rc.local

.
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
printf "My IP address is %s\n" "$_IP"
fi
swapon /dev/sda2
service dphys-swapfile stop
exit 0

b)ラスビアンで　ハイレゾ編

まず
# aptitude update
# aptitude upgrade
# rpi-update
をします

なので

/boot/config.txt
------------------------------------------
dtoverlay=hifiberry-dacplus
dtparam=audio=on

●あとはi2s-DACを常用にするために

　メニューからPreferences > Audio Device Settingsを選びます。

　デフォルトではSound card の欄にはbcm2835 ALSA(Alsa mixer)しか出ていませんが、HypaerberryなんたらDAC(Alsa mixer)が選べます。

　Hypaerberryなんたら(Alsa mixer)を選び、Select Contorolsをクリックすると、Hypaerberryなんたらの機能が出るので、Analogueにチェックしました。
DSP Proguramをチェックすると、内部のフィルタなどの制御ができます。

　この設定をデフォルトにするため、Make Defaultをクリックします。

　OKを押します。

　これ以降、HDMIではなくi2s-DACボードから音が出ます。

１）日本語環境　

素描だけ

pi　の　パスワードは　raspberry
sudo su で　root権限になれる

aptitude search ipa | grep gothic　ー>fonts-ipafont-gothic

aptitude install fcitx-mozc im-config zenity

dpkg-revonfigure locales

dpkg-revonfigure tzdata

nano /etc/defaults/keyboard

２）wifi access point をつくる

ただ　英語の

https://frillip.com/using-your-raspberry-pi-3-as-a-wifi-access-point-with-hostapd/

のとおり

最終のスクリプトは

./wifi-accessPoint.bat
sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"

iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT

service hostapd start
service dnsmasq start

aptitude install hostapd dnsmasq

bogus-priv

dhcp-range=172.24.1.50,172.24.1.55,12h

３）NGINX

nginxの　change ｒｏｏｔは　ー＞　 /var/www/html/
