cobbler関係コマンドメモ

今日は cobbler 関連のコマンドを自分の備忘としてメモです。

設定のチェック


設定のチェックは「cobbler check」


問題があれば、該当箇所のメッセージが出力されるので、そこを直すだけ。楽ですね。

# cobbler check
The following are potential configuration items that you may want to fix:

1 : service dhcpd is not running

Restart cobblerd and then run 'cobbler sync' to apply changes.


何も無ければこんな感じです。

# cobbler check
No configuration problems found.  All systems go.

設定の再読み込み


何か変えたらとりあえず「cobbler sync」が良さそうです。
下は自分が作った環境で発行してみた結果です。

設定一覧の表示

簡単に表示するなら、「cobbler list」

# cobbler list
distros:
   CentOS5-i386
   CentOS5-xen-i386

profiles:
   CentOS5-i386
   CentOS5-xen-i386

systems:

repos:

images:


もう少し詳細に見たい場合は「cobbler report」

# cobbler report

「cobbler status」で実行結果が見られるようですね。

# cobbler status
ip             |target              |start            |state

データのインポート

「cobbler import」でローカルメディアを使ったインポートが出来ます

エントリの操作

追加・・・「cobbler add」
削除・・・「cobbler remove」
複製・・・「cobbler copy」
名前変更・・・「cobbler rename」
編集・・・「cobbler edit」

です。


実行例をいくつか。

# cobbler distro rename --name=CentOS5-i386 --newname=CentOS5-2-i386
# cobbler distro copy --name=CentOS5-i386 --newname=CentOS5-2-i386

# cobbler profile copy --name=CentOS5-i386 --newname=CentOS5-2-i386
# cobbler profile edit --name=CentOS5-2-i386 --kickstart=/var/lib/cobbler/kickstarts/centos5.ks

# cobbler repo add --mirror=http://ftp.jaist.ac.jp/pub/Linux/CentOS/5/ --name=CentOS5-i386
# cobbler repo remove --name=CentOS5-i386

# cobbler system add --name=centos5-pxe-test --profile=CentOS5-2-i386 --mac=XX:XX:XX:XX:XX:XX:XX
