Fedora15 で Cobbler 環境構築
Cobbler = ネットワークブート用ユーティリティパッケージ
Cobbler のバージョンは以下のとおり。
$ sudo cobbler version Cobbler 2.0.11 source: ?, ? build time: Tue Apr 26 19:08:26 2011
以下、実際に行なった手順。
Fedora 15インストール
↓
iptables,selinux,ipv6無効化
↓
yum-plugin-fastestmirror インストール＆システム最新化
↓
VMWare環境なので、VMWareToolsをインストール
必要なパッケージをインストール & 設定
$ sudo yum -y install cobbler dhcp syslinux $ sudo vi /etc/cobbler/settings
manage_dhcp: 1 next_server: <DHCPサーバで通知するTFTPサーバのIP、当例の場合は配布サーバと同一つまり自分のIPアドレス> server: <配布サーバのIPまはFQDN、つまり当例の場合は同上>
$ sudo vi /etc/cobbler/dhcp.template
subnet 192.168.135.0 netmask 255.255.255.0 {
option routers <default_gateway>;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.135.100 192.168.135.254;
filename "/pxelinux.0";
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
}
NIC が2枚あるのでどちらのインターフェースを DHCP に利用するかを設定。
$ sudo vi /etc/sysconfig/dhcpd
DHCPDARGS=eth0
ここで、cobbler を起動 & 設定チェック
$ sudo /etc/rc.d/init.d/cobblerd start $ sudo chkconfig cobblerd on $ sudo cobbler check httpd does not appear to be running and proxying cobbler $ sudo /etc/rc.d/init.d/httpd start $ sudo chkconfig httpd on $ sudo reboot $ sudo cobbler check The following are potential configuration items that you may want to fix: 1 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements. 2 : change 'disable' to 'no' in /etc/xinetd.d/tftp 3 : change 'disable' to 'no' in /etc/xinetd.d/rsync 4 : since iptables may be running, ensure 69, 80, and 25151 are unblocked 5 : debmirror package is not installed, it will be required to manage debian deployments and repositories 6 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one Restart cobblerd and then run 'cobbler sync' to apply changes. $ sudo cobbler get-loaders $ sudo vi /etc/xinetd.d/tftp $ sudo vi /etc/xinetd.d/rsync
// disable = yes
↓
disable = no$ sudo /etc/rc.d/init.d/xinetd restart $ sudo chkconfig tftp on $ sudo chkconfig rsync on $ sudo yum -y install debmirror $ sudo cobbler check The following are potential configuration items that you may want to fix: 1 : since iptables may be running, ensure 69, 80, and 25151 are unblocked 2 : comment 'dists' on /etc/debmirror.conf for proper debian support 3 : comment 'arches' on /etc/debmirror.conf for proper debian support 4 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one $ sudo vi /etc/debmirror.conf
@dists="sid";
@arches="i386";
↓
# @dists="sid";
# @arches="i386";$ openssl passwd -1 -salt Q9QuRBrc $1$Q9QuRBrc$xq6YBrbLH4qEiN.rf1nWF0 $ sudo vi /etc/cobbler/settings
default_password_crypted: "$1$Q9QuRBrc$xq6YBrbLH4qEiN.rf1nWF0"
$ sudo /etc/rc.d/init.d/cobblerd restart $ sudo cobbler check The following are potential configuration items that you may want to fix: 1 : since iptables may be running, ensure 69, 80, and 25151 are unblocked Restart cobblerd and then run 'cobbler sync' to apply changes.
iptables の機能をオフにしてるのに↑のメッセージが出るが無視。
いよいよ sync 。
$ sudo cobbler sync
・・・

!!! TASK FAILED !!!
失敗(´・ω・｀)。
Fedora15 から一部サービスの管理が init から systemctl に変更になったため、
/etc/rc.d/init.d/dhcpd
が削除された模様。
dhcpd を再起動している部分を書き換え。
$ sudo vi /usr/lib/python2.7/site-packages/cobbler/modules/sync_post_restart_services.py
//44行目
rc = utils.subprocess_call(logger,"/etc/rc.d/init.d/dhcpd restart", shell=True)
↓
rc = utils.subprocess_call(logger,"systemctl restart dhcpd.service", shell=True)サービスを再起動して変更を適用し、 sync
$ sudo /etc/rc.d/init.d/cobblerd restart $ sudo cobbler sync
ネットワークブート＆インストールに必要な情報をDVDからインポート。
ついでに、ローカルリポジトリを構築。
$ sudo mount /dev/cdrom /mnt $ sudo cobbler import --path=/mnt --name=Fedora15-x86_64 $ sudo cobbler repo add --name=Fedora15-x86_64 --mirror=rsync://ftp.riken.jp/fedora/releases/15/Everything/x86_64/os/ $ sudo cobbler repo add --name=Fedora15-x86_64-updates --mirror=rsync://ftp.riken.jp/fedora/updates/15/x86_64/ $ sudo cobbler reposync
かなり、放置。
続きは後日。
