基于Rocky Linux 9搭建 dhcp+tftp+nginx+php-fpm 的ipxe自动引导服务器

第一步：安装相应软件

# 安装并设置自动启动
    dnf install dhcp-server ;systemctl enable dhcpd   ;systemctl start dhcpd
    dnf install tftp-server ;systemctl enable tftp    ;systemctl start tftp
    dnf install nginx       ;systemctl enable nginx   ;systemctl start nginx
    dnf install php-fpm     ;systemctl enable php-fpm ;systemctl start php-fpm

第二步：将引导服务器所需要的ipxe程序放置到tftp路径下，并重启tftp服务，（使用udp 69端口）

# 适用于bios方式的
    ls -l /var/lib/tftpboot/undionly.kpxe
    chown apache. /var/lib/tftpboot/undionly.kpxe
    chmod 644 /var/lib/tftpboot/undionly.kpxe

# 适用于uefi方式的
    ls -l /var/lib/tftpboot/ipxe.efi
    chown apache. /var/lib/tftpboot/ipxe.efi
    chmod 644 /var/lib/tftpboot/ipxe.efi

# 重启tftp服务
    systemctl restart tftp

第三步：修改dhcp配置文件，并重启dhcpd服务，（使用udp 67/68端口）

cat > /etc/dhcp/dhcpd.conf << EOF
# DHCP Server Configuration file.
#   see /usr/share/doc/dhcp-server/dhcpd.conf.example
#   see dhcpd.conf(5) man page
