Automating installations and setting up PXE (Preboot Execution Environment) boots on Linux Mint can streamline the deployment process for multiple systems. Here’s a guide to help you get started:
|
||
|
||
### Automated Installations
|
||
|
||
1. **Using Preseed Files**:
|
||
- Preseed files allow you to automate the installation process by providing answers to the installation prompts.
|
||
- Create a preseed file (`preseed.cfg`) with your configuration:
|
||
```plaintext
|
||
d-i debian-installer/locale string en_US
|
||
d-i keyboard-configuration/xkb-keymap select us
|
||
d-i netcfg/get_hostname string mint
|
||
d-i netcfg/get_domain string local
|
||
d-i mirror/country string manual
|
||
d-i mirror/http/hostname string archive.ubuntu.com
|
||
d-i mirror/http/directory string /ubuntu
|
||
d-i mirror/http/proxy string
|
||
d-i passwd/root-password password rootpassword
|
||
d-i passwd/root-password-again password rootpassword
|
||
d-i passwd/user-fullname string User
|
||
d-i passwd/username string user
|
||
d-i passwd/user-password password userpassword
|
||
d-i passwd/user-password-again password userpassword
|
||
d-i clock-setup/utc boolean true
|
||
d-i time/zone string UTC
|
||
d-i partman-auto/method string regular
|
||
d-i partman-auto/choose_recipe select atomic
|
||
d-i partman/confirm boolean true
|
||
d-i partman/confirm_nooverwrite boolean true
|
||
d-i partman/confirm_write_new_label boolean true
|
||
```
|
||
- Use the preseed file during installation by appending it to the boot parameters:
|
||
```plaintext
|
||
linux /install/vmlinuz auto=true priority=critical preseed/url=http://yourserver/preseed.cfg
|
||
```
|
||
|
||
2. **Using Kickstart**:
|
||
- Kickstart files are another method for automating installations, commonly used with Red Hat-based distributions but also supported by Debian-based systems.
|
||
- Create a kickstart file (`ks.cfg`) with your configuration:
|
||
```plaintext
|
||
lang en_US
|
||
keyboard us
|
||
timezone UTC
|
||
rootpw rootpassword
|
||
user user --password userpassword
|
||
reboot
|
||
```
|
||
- Use the kickstart file during installation by appending it to the boot parameters:
|
||
```plaintext
|
||
linux /install/vmlinuz ks=http://yourserver/ks.cfg
|
||
```
|
||
|
||
### Setting Up PXE Boot
|
||
|
||
1. **Install and Configure a TFTP Server**:
|
||
- Install the TFTP server:
|
||
```bash
|
||
sudo apt-get install tftpd-hpa
|
||
```
|
||
- Configure the TFTP server by editing `/etc/default/tftpd-hpa`:
|
||
```plaintext
|
||
TFTP_USERNAME="tftp"
|
||
TFTP_DIRECTORY="/var/lib/tftpboot"
|
||
TFTP_ADDRESS="0.0.0.0:69"
|
||
TFTP_OPTIONS="--secure"
|
||
```
|
||
- Restart the TFTP server:
|
||
```bash
|
||
sudo systemctl restart tftpd-hpa
|
||
```
|
||
|
||
2. **Install and Configure a DHCP Server**:
|
||
- Install the DHCP server:
|
||
```bash
|
||
sudo apt-get install isc-dhcp-server
|
||
```
|
||
- Configure the DHCP server by editing `/etc/dhcp/dhcpd.conf`:
|
||
```plaintext
|
||
subnet 192.168.1.0 netmask 255.255.255.0 {
|
||
range 192.168.1.10 192.168.1.100;
|
||
option routers 192.168.1.1;
|
||
option domain-name-servers 8.8.8.8, 8.8.4.4;
|
||
filename "pxelinux.0";
|
||
next-server 192.168.1.1;
|
||
}
|
||
```
|
||
- Restart the DHCP server:
|
||
```bash
|
||
sudo systemctl restart isc-dhcp-server
|
||
```
|
||
|
||
3. **Prepare PXE Boot Files**:
|
||
- Download and extract the PXE boot files:
|
||
```bash
|
||
sudo apt-get install syslinux
|
||
sudo cp /usr/lib/syslinux/pxelinux.0 /var/lib/tftpboot/
|
||
sudo mkdir -p /var/lib/tftpboot/pxelinux.cfg
|
||
sudo cp /usr/lib/syslinux/menu.c32 /var/lib/tftpboot/
|
||
sudo cp /usr/lib/syslinux/memdisk /var/lib/tftpboot/
|
||
sudo cp /usr/lib/syslinux/mboot.c32 /var/lib/tftpboot/
|
||
sudo cp /usr/lib/syslinux/chain.c32 /var/lib/tftpboot/
|
||
```
|
||
- Create a PXE configuration file (`/var/lib/tftpboot/pxelinux.cfg/default`):
|
||
```plaintext
|
||
DEFAULT menu.c32
|
||
PROMPT 0
|
||
TIMEOUT 300
|
||
ONTIMEOUT local
|
||
MENU TITLE PXE Boot Menu
|
||
|
||
LABEL Linux Mint
|
||
MENU LABEL Install Linux Mint
|
||
KERNEL /install/vmlinuz
|
||
APPEND initrd=/install/initrd.gz auto=true priority=critical preseed/url=http://yourserver/preseed.cfg
|
||
```
|
||
|
||
4. **Boot from PXE**:
|
||
- Configure your client machines to boot from the network (PXE) in the BIOS/UEFI settings.
|
||
- The client machines should now boot from the PXE server and start the automated installation process.
|
||
|
||
These steps should help you set up automated installations and PXE boots on Linux Mint¹²³⁴. If you have any specific questions or need further assistance, feel free to ask!
