**Step 1: Create the Bash Script** ```bash sudo nano /usr/local/bin/start_wifi.sh ``` Add the following content to the script: ```bash #!/bin/bash # Set the interface and SSID details INTERFACE="wlan0" SSID="your_wifi_ssid" PASSWORD="your_wifi_password" # Make sure no previous configuration interferes sudo killall wpa_supplicant sudo dhcpcd -x $INTERFACE # Ensure the wireless interface is up sudo ip link set $INTERFACE up # Create a wpa_supplicant configuration file WPA_CONF="/etc/wpa_supplicant/wpa_supplicant.conf" wpa_passphrase "$SSID" "$PASSWORD" | sudo tee $WPA_CONF > /dev/null # Start wpa_supplicant sudo wpa_supplicant -B -i $INTERFACE -c $WPA_CONF # Obtain an IP address sudo dhcpcd $INTERFACE ``` Make sure to replace `your_wifi_ssid` and `your_wifi_password` with your actual WiFi network's SSID and password. **Step 2: Make the Script Executable** ```bash sudo chmod +x /usr/local/bin/start_wifi.sh ``` **Step 3: Create a Systemd Service File** ```bash sudo nano /etc/systemd/system/start_wifi.service ``` Add the following content to the service file: ```ini [Unit] Description=Start WiFi at boot After=network.target [Service] ExecStart=/usr/local/bin/start_wifi.sh RemainAfterExit=true [Install] WantedBy=multi-user.target ``` **Step 4: Reload Systemd and Enable the Service** ```bash sudo systemctl daemon-reload sudo systemctl enable start_wifi.service sudo systemctl start start_wifi.service ``` Your Raspberry Pi should now connect to the Wi-Fi network automatically on boot. If you want to connect to hidden networks or multiple networks, edit the `wpa_supplicant.conf` file located at `/etc/wpa_supplicant/wpa_supplicant.conf` and add the following configuration: ```bash network={ priority=1 # Higher priority networks are attempted first ssid="Your_Wi-Fi_Name" psk="Your_Wi-Fi_Password" key_mgmt=WPA-PSK scan_ssid=1 # Hidden network priority=2 ssid="Enterprise_Wi-Fi_Name" key_mgmt=WPA-EAP eap=PEAP # or TTLS, TLS, FAST, LEAP identity="Your_Username" password="Your_Password" phase1="peaplabel=0" # or "peapver=0" for PEAPv0 phase2="auth=MSCHAPV2" # or "auth=MSCHAP" for MSCHAPv1 } ``` Restart the `wpa_supplicant` service to apply the changes: ```bash sudo systemctl restart wpa_supplicant ``` See the [wpa_supplicant example file](https://w1.fi/cgit/hostap/plain/wpa_supplicant/wpa_supplicant.conf) for more information on the configuration options.

**Synchronize your system clock:** *Install `chrony` for time synchronization:* ```bash sudo apt install -y chrony # For Debian/Ubuntu sudo yum install -y chrony # For RHEL/CentOS/Alma sudo dnf install -y chrony # # For RHEL/CentOS/Alma 9^ sudo zypper install -y chrony # For openSUSE sudo pacman -S chrony # For Arch Linux ``` Activate and synchronize time immediately with `chrony`: ```bash sudo chronyc makestep ``` **Update your package list:** *Regular updates to your package list ensure access to the latest software and security patches.* ```bash sudo apt update # For Debian/Ubuntu sudo yum makecache # For RHEL/CentOS/Alma sudo dnf makecache # For RHEL/CentOS/Alma 9^ sudo zypper refresh # For openSUSE sudo pacman -Sy # For Arch Linux ``` **Enable additional repositories:** *For systems that utilize EPEL and other special repositories, you may need to enable them to access a wider range of available packages.* For Debian/Ubuntu: ```bash sudo add-apt-repository universe sudo apt update ``` For RHEL/CentOS/Alma and Fedora: ```bash sudo yum install -y epel-release # For RHEL/CentOS/Alma sudo dnf install -y epel-release # For RHEL/CentOS/Alma 9^ sudo yum makecache --timer # For RHEL/CentOS/Alma sudo dnf makecache --timer # For RHEL/CentOS/Alma 9^ ``` **Install Development Tools:** *Development tools are essential for building packages and compiling software. Ensure you have the necessary tools installed.* For Debian/Ubuntu: ```bash sudo apt install -y build-essential ``` For RHEL/CentOS/Alma and Fedora: ```bash sudo yum groupinstall -y "Development Tools" # For RHEL/CentOS/Alma sudo dnf groupinstall -y "Development Tools" # For RHEL/CentOS/Alma 9^ ``` **Install System Dependencies** 1. **Docker**: Required for containerization. ```bash sudo apt-get install -y docker.io # For Debian/Ubuntu sudo yum install -y docker # For RHEL/CentOS/Alma sudo dnf install -y docker # For RHEL/CentOS/Alma 9^ sudo zypper install -y docker # For openSUSE sudo pacman -S docker # For Arch Linux ``` then `sudo systemctl enable --now docker` 2. **NGINX**: Required for reverse proxy for the web interface. ```bash sudo apt-get install -y nginx # For Debian/Ubuntu sudo yum install -y nginx # For RHEL/CentOS/Alma sudo dnf install -y nginx # For RHEL/CentOS/Alma 9^ sudo zypper install -y nginx # For openSUSE sudo pacman -S nginx # For Arch Linux ```
