NAGIOSのインストール
この手順に沿ってインストールを試みる。
http://www.atmarkit.co.jp/fnetwork/rensai/netman05/netman01.html
記事の中ではmakeを使ってインストールしているが、ここではまず、yumを試す。
# yum -y install nagios
インストールができた。詳細はインストールログ参照。

Nagios 2.5

Usage: nagios [option] <main_config_file>
Options:
-v Reads all data in the configuration files and performs a basic
verification/sanity check. Always make sure you verify your
config data before (re)starting Nagios.
-s Shows projected/recommended check scheduling information based
on the current data in the configuration files.
-d Starts Nagios in daemon mode (instead of as a foreground process).
This is the recommended way of starting Nagios for normal operation.

Nagiosの追加インストール
[root@linux38 ~]# yum -y install nagios
だけだと,
/usr/share/nagiosの中にhtmlというディレクトリしか作成されていなかった。本当は
- bin/ Nagiosのコアプログラム
- etc/ コンフィグファイル
- libexec/ プラグインモジュール
- sbin/ CGIプログラム
- share/ HTMLファイル
- var/ ログファイル用の空ディレクトリ
こんな風にいろいろ出来るらしい。ということで、cactiの時みたいに関連パーツのインストールを試みる。
#yum -y install nagios*
追加インストール
すごくたくさんいろいろインストールされた

webサーバ用のコンフィグ(nagios.confの作成)もやってくれてる。楽。

cgi用の動的コンテンツはこっちに作成されている。 nagios.confを読むと、いろんなディレクトリ構造がわかった。

設定ファイルたちはこのあたりにいる。

アカウントも出来てた。
/etc/passwd nagios:x:101:101::/var/spool/nagios:/sbin/nologin
パーミッション（というか所有者）の変更（rootになって作業をしてたので）
[root@linux38 lib]# chown -R nagios:nagios /usr/lib/nagios/ [root@linux38 lib]# chown -R nagios:nagios /usr/share/nagios/ [root@linux38 lib]#
[root@linux38 html]# more /etc/httpd/conf.d/nagios.conf ScriptAlias /nagios/cgi-bin/ /usr/lib/nagios/cgi-bin/ <Directory /usr/lib/nagios/cgi-bin/> Options ExecCGI order deny,allow deny from all allow from 127.0.0.1 192.168.10.

変更した設定を読み込ませるため、apacheを再起動した。
[root@linux38 html]# /etc/init.d/httpd restart httpd を停止中: [ OK ] httpd を起動中: [ OK ]
http://192.168.10.38/nagios/ にアクセスできるんだが、初期IDと初期パスワードがわかんなくてログインできない。 10行くらい前のnagios.confに書いてあった。ベーシック認証が使われている。パスワードファイルの場所も書いてる。
http://nagios.x-trans.jp/Nagios-doc/JAPANESE/cgiauth.html
[TODO]暫定で認証関係の行を削除した。（元ファイルはコピーして取っておいてる）
変更した設定を読み込ませるため、apacheを再起動した。
[root@linux38 html]# /etc/init.d/httpd restart httpd を停止中: [ OK ] httpd を起動中: [ OK ]
アクセスできた！！ただし、/cgi-bin/以下の動的コンテンツが全部500エラー。
終わってから振り返ると、ここからの戦いが長かった
コンフィグファイルの作り方
- http://www.atmarkit.co.jp/fnetwork/tokusyuu/22tool/03.html に載ってるようなコンフィグファイルに基づいて監視任務を実行するようだ。このコンフィグファイルはどのように作るのだろう。
- 候補
- ゼロからviで手書き。
- テンプレートを元にviで手書き。
- 対話形式で作成。
- GUI（ブラウザから）
いざ設定開始
ここを参考にする。
# plugin release rather than the one provided with Nagios. cfg_file=/etc/nagios/checkcommands.cfg # Misc commands (notification and event handler commands, etc) cfg_file=/etc/nagios/misccommands.cfg # You can split other types of object definitions across several # config files if you wish (as done here), or keep them all in a # single config file.
cfg_file=/etc/nagios/minimal.cfg
編集後/etc/nagios/nagios.cfg
# plugin release rather than the one provided with Nagios. #cfg_file=/etc/nagios/checkcommands.cfg # Misc commands (notification and event handler commands, etc) #cfg_file=/etc/nagios/misccommands.cfg # You can split other types of object definitions across several # config files if you wish (as done here), or keep them all in a # single config file. cfg_file=/etc/nagios/minimal.cfg
直したらコマンドラインから実行して、エラーがゼロになるまで直しを繰り返す。
[root@linux38 nagios]# nagios -v /etc/nagios/nagios.cfg
直しきったら（エラーがゼロになったら） Nagiosをデーモンとして手動起動させた。
[root@linux38 nagios]# /etc/init.d/nagios restart
