Jenkinsのセットアップ（インストールとsshの設定）

Jekinsのインストール，設定メモ．Markdownで残っていたので公開する．

install & run (for mac)

$ brew install jenkins # インストール
$ java -jar /usr/local/opt/jenkins/libexec/jenkins.war # 起動．デフォルトポート:8080

Publish over SSH

JenkinsからリモートサーバへSSH＆SCPするために使用したプラグイン． Jenkinsのホストで生成した秘密鍵と公開鍵を用いてリモートサーバにアクセスする．

ssh keyの生成 (<ホームディレクトリ>/.ssh/に秘密鍵id_rsa，公開鍵id_rsa.pubが生成されたとする)

[Jenkins host]
$ ssh-keygen -t rsa
Enter file in which to save the key (<ホームディレクトリ>/.ssh/id_rsa): <鍵の保存先と名前>
Enter passphrase (empty for no passphrase): <鍵のパスフレーズ>

公開鍵をリモートサーバにコピー
公開鍵の登録

[remote server]
$ cat id_rsa.pub >> ~/.ssh/authorized_keys

Jenkinsに登録
- [Jenkinsの管理] -> [システムの設定] -> Publish over SSH
  - 鍵の設定
    - Passphrase : 設定したパスフレーズ
    - Path to key : 秘密鍵を絶対パスで指定
  - Remote Serverの追加
    - [追加] をクリックし，出現した項目に以下を入力
      - Name : サーバの名前
      - Hostname: サーバのアドレス or URL
      - Username: アクセスするユーザ
    - [Test Configuration] をクリック．接続テスト　
ジョブ毎の設定
- [設定]
  - ビルド環境以下の2つが設定可能となる(上がビルド前，下がビルド後に実行)
    - Send files or execute commands over SSH before the build starts
    - Send files or execute commands over SSH after the build runs
  - 各設定
    - Name : 設定したサーバの名前
    - Transfers: 送るファイル，実行するコマンド
  - [Add Transfer Set] で実行するサーバ，コマンドを増やす事ができる．
  - Tips
    - [高度な設定]により設定を追加できる．
      - Exec timeout (ms) : SSHで実行する操作のタイムアウトの時間を設定．時間がかかる処理は数を増やしておく．

pluginを用いない場合のSSHの設定

ビルドのシェルスクリプトでsshのコマンドを利用する．

$ ssh -i <秘密鍵> <リモート先> <実行コマンド>

sudoのパスワードと秘密鍵のパスフレーズを突破する必要があるため，以下の設定を行っておく必要がある．

sudoのパスワード省略
- visudoで/etc/sudoersに以下の行を追加する．%sudo ALL=(ALL:ALL) ALLの下に追記した．

$ sudo visudo

<username> ALL=(ALL) NOPASSWD:ALL

秘密鍵のパスフレーズの省略
- ホスト（Jenkins）側の設定．Macはkeychain使えって．

[Mac]
$ ssh-add -l # 秘密鍵の登録状況
$ ssh-add <秘密鍵>

[Linux]
$ eval `ssh-agent`
$ ssh-add -l
$ ssh-add <秘密鍵>

Tips： sudo できなくなったら. Ubuntuの場合

Shiftを押しながら起動．シングルユーザモード（recoverey mode）でログイン．
root Drop to root shell prompt

なんでこんなTipsがあるかって？　察して．

Preseedの設定

モチベーション

Cobblerで自動インストールできるようになったは良いが，いろいろ設定を変えたい．
自動デプロイまで視野に入れるなら，せめてsshも勝手に入っていて欲しい．

最初からTips

基本はサンプルから

Preseedのサンプルがここ( https://www.debian.org/releases/wheezy/example-preseed.txt )に公開されている．基本はこれを参考にすすめる．コメント中にある$を消すかエスケープしないと動作しない．
あとこちらのサイトにお世話になりました．感謝． http://www.nofuture.tv/linux/debianautoinstall

ユーザ名/パスワードの変更

下記の設定でubuntu/ubuntuとなる．どの項目で何が設定されるかは推して知るべし．
パスワードはハッシュ値で設定されている．/etc/shadow を見ると自分のマシンで設定したパスワードに対応したハッシュの値を見ることができる．

d-i passwd/user-fullname string ubuntu
d-i passwd/username string ubuntu
d-i passwd/user-password-crypted password $6$.1eHH0iY$ArGzKX2YeQ3G6U.mlOO3A.NaL22Ewgz8Fi4qqz.Ns7EMKjEJRIW2Pm/TikDptZpuu7I92frytmk5YeL.9fRY4.

パッケージの追加

sshをインストールしてもらう．以下の行を追加．
gitなどもインストールできる．後ろに一つスペースを開けて，gitと追加するだけ．

d-i pkgsel/include string ssh

Preseedファイル

いろいろ試行錯誤したし(主にコメント中の$のせい)，動作保証なし．CobblerによるPXEブートしか試してない．
Ubuntu14.04が入る．
trustyのapt-mirrorが必要．IPは192.168.10.3．
NTPはデフォルト(ntp.ubuntu.com)のまま．
ユーザ名はUbuntu，パスもUbuntu．
sshをインストールする．
!!注意：$は\でエスケープしないと動かなかった．下記のPreseedはエスケープ済み．

# installations on non-networked devices where the network questions,
# warning and long timeouts are a nuisance.
#d-i netcfg/enable boolean false

# netcfg will choose an interface that has link if possible. This makes it
# skip displaying a list if there is more than one interface.

### Partitioning
## Partitioning example
# If the system has free space you can choose to only partition that space.
# This is only honoured if partman-auto/method (below) is not set.
#d-i partman-auto/init_automatically_partition select biggest_free

# Alternatively, you may specify a disk to partition. If the system has only
# one disk the installer will default to using that, but otherwise the device
# name must be given in traditional, non-devfs format (so e.g. /dev/hda or
# /dev/sda, and not e.g. /dev/discs/disc0/disc).
# For example, to use the first SCSI/SATA hard disk:
#d-i partman-auto/disk string /dev/sda
# In addition, you'll need to specify the method to use.
# The presently available methods are:
# - regular: use the usual partition types for your architecture
# - lvm:     use LVM to partition the disk
# - crypto:  use LVM within an encrypted partition
d-i partman-auto/method string regular
# Or provide a recipe of your own...
# If you have a way to get a recipe file into the d-i environment, you can
# just point at it.
#d-i partman-auto/expert_recipe_file string /hd-media/recipe

# If not, you can put an entire recipe into the preconfiguration file in one
# (logical) line. This example creates a small /boot partition, suitable
# swap, and uses the rest of the space for the root partition:
#d-i partman-auto/expert_recipe string                         \
#      boot-root ::                                            \

#                      mountpoint{ / }                         \
#              .                                               \
#              64 512 300% linux-swap                          \

#              .

#d-i partman-auto/expert_recipe string                       \
#      boot-root ::                                          \
#              500 10000 1000000000 ext4                     \
#                      $primary{ } $bootable{ }              \
#                      method{ format } format{ }            \
#                      use_filesystem{ } filesystem{ ext4 }  \
#                      mountpoint{ / }                       \

#              .

# The full recipe format is documented in the file partman-auto-recipe.txt
# included in the 'debian-installer' package or available from D-I source
# repository. This also documents how to specify settings such as file
# system labels, volume group names and which physical devices to include
# in a volume group.

## Partitioning using RAID
# The method should be set to "raid".

# Specify the disks to be partitioned. They will all get the same layout,
# so this will only work if the disks are the same size.
#d-i partman-auto/disk string /dev/sda /dev/sdb

# Next you need to specify the physical partitions that will be used.
#d-i partman-auto/expert_recipe string \

#              .                                            \
#              64 512 300% raid                             \
#                      method{ raid }                       \
#              .                                            \

### Base system installation
# Configure APT to not install recommended packages by default. Use of this
# option can result in an incomplete system and should only be used by very

### Preseeding other packages
# Depending on what software you choose to install, or if things go wrong
# during the installation process, it's possible that other questions may
# be asked. You can preseed those too, of course. To get a list of every
# possible question that could be asked during an install, do an
# installation, and then run these commands:
#   debconf-get-selections --installer > file
#   debconf-get-selections >> file

#### Advanced options
### Running custom commands during the installation
# d-i preseeding is inherently not secure. Nothing in the installer checks
# for attempts at buffer overflows or other exploits of the values of a
# preconfiguration file like this one. Only use preconfiguration files from
# trusted locations! To drive that home, and because it's generally useful,
# here's a way to run any shell command you'd like inside the installer,
# automatically.

# This first command is run as early as possible, just after
# preseeding is read.
# d-i preseed/early_command string anna-install some-udeb
# This command is run immediately before the partitioner starts. It may be
# useful to apply dynamic partitioner preseeding that depends on the state
# of the disks (which may not be visible when preseed/early_command runs).
# d-i partman/early_command \
#       string debconf-set partman-auto/disk "\$(list-devices disk | head -n1)"
# This command is run just before the install finishes, but when there is
# still a usable /target directory. You can chroot to /target and use it

Ubuntu ServerにCobblerインストール

UbuntuサーバにCobblerをインストールして使ってみる． CobblerからインストールするのもUbuntu

最終更新 2014/05/02

モチベーション

Ubuntu Severを何台かインストール・セットアップしたい。一台一台インストールは面倒。
どうせなら外から管理しよう。PXEブートの環境用意しなきゃ。
CobblerがDHCPやTFTPを良きに管理してくれるらしい。使ってみよう。

Install

$ sudo apt-get install cobbler cobbler-web

チェック

$ sudo cobbler check

追加しろと言われるので，，，，

$ sudo apt-get install debmirror

dhcpdのインストール

どのdhcp入れるのが良いかは詳しくない．

sudo apt-get install isc-dhcp-server

dhcpの設定変更

Cobblerの設定するとdhcp側の設定を変えなくても勝手に反映される．ルーティングとかDNSとかしないのでコメントアウトしてある．

$ sudo vi /etc/cobbler/dhcp.template

# ******************************************************************
# Cobbler managed dhcpd.conf file
#
# generated from cobbler dhcp.conf template ($date)
# Do NOT make changes to /etc/dhcpd.conf. Instead, make your changes
# in /etc/cobbler/dhcp.template, as /etc/dhcpd.conf will be
# overwritten.
#
# ******************************************************************

ddns-update-style interim;

allow booting;
allow bootp;

ignore client-updates;
set vendorclass = option vendor-class-identifier;

subnet 192.168.0.0 netmask 255.255.255.0 {
#     option routers             192.168.0.1;
#     option domain-name-servers 192.168.0.1;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.0.100 192.168.0.254;
     filename                   "/pxelinux.0";
     default-lease-time         21600;
     max-lease-time             43200;
     next-server                192.168.0.2;
}

いろいろ設定

以下の3点を設定

manage_dhcpを0→1に．
next_serverを自IPアドレスに(デフォルトはeth0)
serverを自IPアドレスに(デフォルトはeth0)

$ sudo vi /etc/cobbler/settings

- manage_dhcp: 0
+ manage_dhcp: 1

next_server: 192.168.0.2

server: 192.168.0.2

サービス再起動

$ sudo service cobbler restart
$ sudo cobbler sync

チェック

$ sudo cobbler check

ユーザ追加

$ sudo htdigest /etc/cobbler/users.digest "cobbler" cobbler

ISOファイルのマウント．ループバックな感じで

$ sudo mount -o loop [isoファイル] /mnt

cobblerへimport

$ sudo cobbler import --name=ubuntu-server --path=mnt --breed=ubuntu

webで確認

preseedのセットアップ

Webでセットしてセーブ

sync

$ sudo service cobbler restart $ sudo cobbler sync

試す．

とりあえず，インストール始まればおｋ

デフォルトの変更

上記の設定では何も触らないと(local)が選択され，PXEブートが開始されない．デフォルトを変更する

$ sudo cobbler system add --name=default --profile=ubuntu1404-server-amd64
$ sudo cobbler sync

もちろん"ubuntu1404-server"には自分がデフォルトに設定したいProfileの名前が入る．

MACアドレスを指定し，個別自動インストール

上記のname部分をMACアドレスにすることで個別にprofileを設定することができる．

$ sudo cobbler system add --name=00:00:00:00:00:01 --profile=ubuntu1204-server-amd64
$ sudo cobbler sync

その他設定いろいろ

ここ（ http://blog.glidenote.com/blog/2012/03/16/cobbler-system-add/ ）とかここ（ http://zinrai.github.io/blog/html/2013/06/22/centos_cobbler_puppet_install.html ）にsystem addの設定についていろいろあった．実際の動作は確かめて無い．
system add の他，system editで編集ができるらしい．
以下オプション
- name
  - system名
- hostname
  - hostname
- profile
  - 使用するprofile
- interface
  - 設定するインターフェース(eth0等)
- mac
  - MACアドレス
- static
  - 0: DHCP，1: 固定IP
- ip
  - ip address
- subnet
  - subnet mask
- gateway
  - gateway address
- name-servers
  - DNSサーバアドレス
- kopts
  - カーネルオプション．シングルクオートで囲む(?)
pxe_just_onceを有効にする(/etc/cobbler/setting で設定する．デフォルトは1で有効)と登録したsystemは1度しかpxe_bootしない．もう1度インストールしたくなったら以下のコマンドを実行

$ sudo cobbler system edit --name=hogehoge-server --netboot-enabled=1

設定の確認は以下のコマンド

$ sudo cobbler report

apt-mirrorをたてる

モチベーション

ローカルでPXEブートしたい．外にはつなぎたくない．でもapt-mirror．．．．
そうだ、自前でローカルにapt-mirrorを立てよう

install

$ sudo apt-get install apt-mirror

configuration

面倒なので全部ミラーした． 12.04と14.04の両方のミラーが欲しいので，preciseとtrustyの2種類を作成する． deb-i386の行はNot Foundが出るのが気に入らないので追加した． PXEブート等を行う際にはdebian-installerのミラーも必要なので注意．

apt-mirror作成

12.04と14.04，さらに共にamd64とi386を用意するので必要なストレージ容量は250GB以上．

でも偉い人が言ってた．ストレージなんてタダみたいなもんだと．

終了に数時間かかります．

$ sudo apt-mirror

自動更新

最後の行のコメントアウトを外しただけ．毎朝４時に更新するらしい．

$ sudo vi /etc/cron.d/apt-mirror

#
# Regular cron jobs for the apt-mirror package
#

　公開

Install apatche2

$ sudo apt-get install apache2

httpの設定

$ sudo ln -s /var/spool/apt-mirror/mirror/jp.archive.ubuntu.com/ubuntu /var/www/ubuntu

Apacheが2.4系だった場合

Ubuntu13.10からapt-getで入るApacheが2.4系になり，上記の操作のみでは公開できない．
Apacheは詳しくないので，Apache2.2系の設定のそれっぽい箇所を2.4のそれっぽいところにコピペしたら動作した．このため，アクセス制御の書式が2.2に準じており，美しくない．あとで治す．
セキュリティ的に危ないので，外部には公開しないように注意．
/etc/apache2/sites-enabled/000-default.conf を修正

- DocumentRoot /var/www/html

+ DocumentRoot /var/www
+ <Directory />
+        Options FollowSymLinks
+        AllowOverride None

+ <Directory /var/www/>
+        Options Indexes FollowSymLinks MultiViews
+        AllowOverride None
