2. Xaiv koj li WIFI coutry ntawm qeb kev faib chaw

3. Teem lub Desktop/CLI teeb tsa hauv cov khau raj xaiv qeb rau Desktop Autologin.

4. Hauv qab cov kev xaiv Advanced xaiv A1 nthuav tawm cov ntaub ntawv system (qhov no ua kom ntseeg tau tias koj siv qhov chaw ntawm tag nrho SD daim npav

5. Tam sim no tawm thiab sudo reboot

Wifi

Tam sim no nws yog lub sijhawm los teeb tsa koj li kev sib txuas wifi tawm ntawm chav kawm koj yuav xav tau daim ntawv pov thawj ntawm koj li wifi.

Ua ntej nkag mus rau hauv paus hom los ntawm kev ua cov lus txib no

Sudo -ib

Tam sim no koj muaj txoj cai tsim nyog los ua cov lus txib no:

Nco ntsoov hloov SSID rau koj lub npe wifi thiab PASSWORD rau koj tus password wifi

Wpa_passphrase “SSID” “PASSWORD” >> /etc/wpa_supplicant/wpa_supplicant.conf

Nkag mus rau WPA Client los ntawm kev ua cov lus txib no:

wpa_cli

Xaiv lub interface

Kev sib txuas wlan0

Reload tus config

Rov kho dua

Kawg tab sis tsis tsawg kawg yog tias nws ua haujlwm. Koj tuaj yeem ua qhov no los ntawm kev nkag mus:

Ip ib

Ntawm no koj tuaj yeem tshawb xyuas yog tias koj muaj tus IP nyob hauv WLAN0 cuam tshuam yog tias tsis sudo reboot (yeej tsis ua tiav (:).

Yog tias koj tsis xis nyob ua nws los ntawm kab hais kom ua koj ib txwm tuaj yeem ua nws ntawm GUI ntawm Raspbian uas yog tus neeg siv tau zoo dua me ntsis.

1. Nruab VNC-viewer ntawm no:
2. Nyem cov ntaub ntawv, kev sib txuas tshiab thiab nkag mus rau IP-chaw nyob bar: 169.254.10.1 thiab xaiv lub npe twg los xij koj xav tau
3. Sau rau hauv lub npe siv: pi thiab tus password raspberry
4. Nyem rau lub cim wifi thiab txuas qhov ntawd

Pob

Tam sim no peb tau txuas nrog internet peb tuaj yeem teeb tsa pob khoom peb xav tau los ua txhua txoj cai.

Ua ntej peb yuav xav tau hloov kho cov npe pob rau qhov tshiab los ntawm kev khiav:

sudo apt hloov tshiab

sudo apt hloov tshiab

Apache Webserver

Peb yuav xav tau tus webserver los khiav peb daim ntawv thov web. Peb tuaj yeem ua tiav qhov no los ntawm kev txhim kho apache webserver los ntawm kev ua cov lus txib no:

sudo apt nruab apach2 -y

Nab hab sej pob

Txhawm rau ua txhua yam haujlwm peb yuav xav tau ob peb pob. Cov no yog cov uas peb yuav xav tau.

• Lub hwj
• Flask-Cors
• Flask-Extension
• Flask-MySQL
• Flask-SocketIO
• Nab hab sej

Koj tuaj yeem nruab lawv los ntawm kev ua cov lus txib no:
