Cobblerを使用して、CentOS / Ubuntuのバッチ展開を自動化します

この記事では主に、CentOS 7.6 Minimal + Cobblerを介したCentOS / Ubuntuの自動インストールについて説明します。

準備＃＃

Aliミラーステーションから、CentOS-7-x86_64-Minimal-1810.isoおよびUbuntu-16.04.5-desktop-amd64.isoをダウンロードし、VMwareを使用してCentOS7仮想マシンを作成します。

環境の初期化

ソフトウェアソースをAliソースに変更します

# yumソース

# バックアップシステムのデフォルトソース
[ root@localhost ~]# mkdir /etc/yum.repos.d/old && mv /etc/yum.repos.d/C*/etc/yum.repos.d/old/[root@localhost ~]# yum clean all

# Aliyumソースを設定する
[ root@localhost ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[ root@localhost ~]# curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

# ピップソース(2.8.4つのバグ)[root@localhost ~]# mkdir ~/.pip
[ root@localhost ~]# cat >~/.pip/pip.conf << EOF
[ global]
trusted-host=mirrors.aliyun.com
index-url=https://mirrors.aliyun.com/pypi/simple/
EOF

SSHを構成する

DNS解決はssh_configでデフォルトで有効になっているため、毎回リモートSSHが非常に遅くなります。

[ root@localhost ~]# sed -i 's%#UseDNS yes%UseDNS no%'/etc/ssh/sshd_config 
[ root@localhost ~]# service sshd restart

SElinuxを無効にする

CentosでCobblerサポートを有効にする場合は、ルートユーザーとしてsetseboolを実行して、ブートイメージを提供するようにSELinuxコンテキストルールを構成する必要があります。 SElinuxの構成はより複雑であるため、ここではSELinuxを直接無効にします。

[ root@localhost ~]# sed -i '/SELINUX/s/enforcing/disabled/'/etc/selinux/config  
[ root@localhost ~]# setenforce 0

対応するファイアウォールルールを構成する

# TFTP
[ root@localhost ~]# firewall-cmd --zone=public--add-port=69/tcp --permanent
[ root@localhost ~]# firewall-cmd --zone=public--add-port=69/udp --permanent

# HTTPD
[ root@localhost ~]# firewall-cmd --zone=public--add-port=80/tcp --permanent
[ root@localhost ~]# firewall-cmd --zone=public--add-port=443/tcp --permanent

# Cobbler
[ root@localhost ~]# firewall-cmd --zone=public--add-port=25150/tcp --permanent
[ root@localhost ~]# firewall-cmd --zone=public--add-port=25150/udp --permanent

# Koanは使用しない場合は閉じることができます
[ root@localhost ~]# firewall-cmd --zone=public--add-port=25151/tcp --permanent

# SambaウィンドウのインストールにはSambaが必要です,それ以外の場合は閉じることができます
[ root@localhost ~]# firewall-cmd --zone=public--add-port=139/tcp --permanent
[ root@localhost ~]# firewall-cmd --zone=public--add-port=445/tcp --permanent
[ root@localhost ~]# firewall-cmd --zone=public--add-port=137/udp --permanent
[ root@localhost ~]# firewall-cmd --zone=public--add-port=138/udp --permanent

# ファイアウォールルールを更新する
[ root@localhost ~]# firewall-cmd --reload

# 開いているすべてのポートを表示
[ root@localhost ~]# firewall-cmd --zone=public--list-ports

Cobblerをインストールする

依存ソフトウェアをインストールする

[ root@localhost ~]# yum install -y cobbler cobbler-web dhcp tftp-server pykickstart httpd xinetd

自動起動を設定する

[ root@localhost ~]# systemctl enable httpd
[ root@localhost ~]# systemctl enable xinetd
[ root@localhost ~]# systemctl enable rsyncd
[ root@localhost ~]# systemctl enable tftp
[ root@localhost ~]# systemctl enable cobblerd

サービス開始

[ root@localhost ~]# systemctl start httpd
[ root@localhost ~]# systemctl start xinetd
[ root@localhost ~]# systemctl start tftp
[ root@localhost ~]# systemctl start cobblerd

構成を確認する

[ root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:1: The 'server' field in/etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work.  This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.2: For PXE to be functional, the 'next_server' field in/etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.3: SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:
 https://github.com/cobbler/cobbler/wiki/Selinux
4: change 'disable' to 'no'in/etc/xinetd.d/tftp
5: 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 inthis 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.6: debmirror package is not installed, it will be required to manage debian deployments and repositories
7: 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 newone8: fencing tools were not found, and are required to use the(optional) power management features. install cman or fence-agents to use them

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

以下は、検査結果の問題の簡単な説明です。

1番目と2番目の項目：cobbler_ipとnext_serverを設定します

cobbler_ipは、cobblerホストIPです。

next_serverはDHCPホストIPです。この実験では、DHCPとCobblerは同じホストです。

[ root@localhost ~]# export cobbler_ip=192.168.0.12[root@localhost ~]# sed -i "s%^server: 127.0.0.1%server: ${cobbler_ip}%g"/etc/cobbler/settings
[ root@localhost ~]# sed -i "s%^next_server: 127.0.0.1%next_server: ${cobbler_ip}%g"/etc/cobbler/settings

項目3：SELinuxとファイアウォールを構成する

SELinuxがオフになっていて、ファイアウォールが構成されているため、無視できます。

項目4：tftp機能をオンにする

[ root@localhost ~]# sed -i '/disable\>/s/\<yes\>/no/'/etc/xinetd.d/tftp

アイテム5：ブートロードをダウンロードする

[ root@localhost ~]# cobbler get-loaders

アイテム6：Ubuntuローカルパッケージイメージをダウンロードする

Ubuntuをインストールする必要がない場合は、変更できます。

[ root@localhost ~]# yum install -y debmirror
[ root@localhost ~]# sed -i 's%^@dists="sid"%#@dists="sid"%g;s%@arches="i386"%#@arches="i386"%g'/etc/debmirror.conf

項目7：システムのインストール後にrootパスワードを設定する

[ root@localhost ~]# export root_pwd=$(openssl passwd -1-salt `openssl rand 15 -base64`'Abcd1234!@#$')[root@localhost ~]# sed -i "s%^default_password_crypted.*%default_password_crypted: \"${root_pwd}\"%g"/etc/cobbler/settings

項目8：電源管理モジュールの取り付け（オプション）

cmanまたはence-agentsのいずれかを選択できますが、ここでは無視されます。

残りの関連部分の変更

# 対応する構成ファイルを変更します
[ root@localhost ~]# sed -i "s%manage_dhcp: 0%manage_dhcp: 1%g"/etc/cobbler/settings
[ root@localhost ~]# sed -i "s%pxe_just_once: 0%pxe_just_once: 1%g"/etc/cobbler/settings

関連サービスを再開する

[ root@localhost ~]# systemctl restart httpd
[ root@localhost ~]# systemctl restart xinetd
[ root@localhost ~]# systemctl restart tftp
[ root@localhost ~]# systemctl restart cobblerd

もう一度確認して、情報が2つしかないことを確認してください。無視してください。

[ root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:1: SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:
 https://github.com/cobbler/cobbler/wiki/Selinux
2: fencing tools were not found, and are required to use the(optional) power management features. install cman or fence-agents to use them

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

cobbler syncを実行して、情報を同期します

[ root@localhost ~]# cobbler sync

*** TASK COMPLETE ***

Cobbler-Webのバグを解決する

https：// $ {cobbler_ip} / cobbler_webを開くと、開いた後に500 Internal ServerErrorエラーが発生します。

Djangoのバージョンが高すぎて互換性がないため、これは2.8.4のバグです。解決：

[ root@localhost ~]# yum install -y python-pip
[ root@localhost ~]# pip2.7 install -U django==1.9.13[root@localhost ~]# systemctl restart cobblerd

ユーザー名とパスワードを設定する

デフォルトのユーザー名とパスワードはcobbler / cobblerです。

[ root@localhost ~]# htdigest -c /etc/cobbler/users.digest Cobbler cobbler #これはユーザー名です
[ root@localhost ~]# systemctl restart cobblerd

もう一度https：// $ {cobbler_ip} / cobbler_webにアクセスしてください

画像をマウント

Winscp、Mobaxtermなどを介してUbuntuおよびCentosイメージをCobblerサーバーの/ tmp /ディレクトリにアップロードします。ここで、net.ifnames = 0 biosdevname = 0 noipv6は、ネットワークカードの名前を均一にeth0にします。

[ root@localhost ~]# mount -t iso9660 -o loop /tmp/CentOS-7-x86_64-Minimal-1810.iso /mnt/[root@localhost ~]# cobbler import--name=CentOS-7.6.1810-x86_64 --path=/mnt/--arch=x86_64
[ root@localhost ~]# cobbler profile edit --name=CentOS-7.6.1810-x86_64 --kopts='net.ifnames=0 biosdevname=0'[root@localhost ~]# mount -t iso9660 -o loop /tmp/ubuntu-16.04.5-server-amd64.iso /mnt/[root@localhost ~]# cobbler import--name=ubuntu-16.04.5-server-x86_64 --path=/mnt/--arch=x86_64

PXEインストールシステムをテストします

2Gのメモリ、2コアのCPU、および20Gのディスクを備えた2つの仮想マシンをVMwareで作成します（空のディスクを選択します）。作成後、スナップショットを作成することを忘れないでください。実験が失敗した場合は、復元してください。

CentOSを選択し、Enterキーを押すと、システムが自動的にインストールされます。
