Ubuntu Cobbler版本升级策略
/etc/cobbler/cobbler.conf)和自定义脚本(如kickstart文件、autoinstall模板),防止升级过程中数据丢失。可使用sudo cp /etc/cobbler/cobbler.conf /etc/cobbler/cobbler.conf.bak命令备份配置文件。https://github.com/cobbler/cobbler),进入“Releases”页面,下载所需版本的新源码压缩包(如cobbler-2.8.5.tar.gz)。/usr/src目录(或其他临时目录),使用命令:sudo tar -zxvf cobbler-*.tar.gz -C /usr/src/。cd /usr/src/cobbler-*
./configure # 检查系统环境并生成Makefile
make # 编译源码
sudo make install # 安装新版本
sudo systemctl restart cobblerdsudo service cobblerd restart
验证升级结果:运行cobbler --version,确认输出的Cobbler版本已更新为目标版本。/var/lib/cobbler/distro_signatures.json文件,添加新版本的签名信息(以24.04为例):"noble": {
"signatures": ["dists", ".disk"],
"version_file": "Release|info",
"version_file_regex": "Suite: noble|Ubuntu 24.04",
"kernel_arch": "linux-headers-(.*)\\.deb",
"supported_arches": ["i386", "amd64"],
"supported_repo_breeds": ["apt"]
}
修改后重启Cobbler服务:sudo systemctl restart cobblerd。cobbler distro remove Ubuntu22),然后重新导入新版本ISO镜像(cobbler import --name Ubuntu24 --path /path/to/ubuntu-24.04.iso),并同步配置:sudo cobbler sync。gcc、make、python3等)为最新版本,避免编译过程中出现依赖错误。可使用sudo apt update && sudo apt upgrade更新依赖。cobbler.conf.bak复制回/etc/cobbler/cobbler.conf),并卸载新版本Cobbler(sudo make uninstall)。
