cactiの立ち上げ

最初はMRTGを使おうと思ってたんだけど、以前から評判になってるMRTGの後継(???)のcactiを使うよう、路線変更しました。

http://cacti.loaded.jp/
以前MRTGを自宅で実験したとき、インストールが面倒だった（結局途中で断念した。前準備の別のインストールがあれこれ必要だということが途中でわかって面倒になったため）
cactiではそのあたりが解消されてる（っぽい）。うたい文句にも書いてある。

追記：mrtgはyumでインストール出来ました。そのうち試してみるかも。

cactiのインストール

MRTGよりもインストールなどが楽になっている→yumでインストール出来るように準備されてるだろう。

[root@linux38 sbin]# yum -y install cacti

インストールできました。依存関係のパッケージ（mysqlとかも）も自動でupdateしてくれました。 apache httpdもcactiの依存対象にされてるみたいなので、個別にapache httpdを入れなくても、このcactiのインストールだけでまとめてインストールしてくれそうです。
cactiユーザの作成までやってくれてます。
/etc/passwd

cacti:x:100:501::/usr/share/cacti:/sbin/nologin

インストールログ

なぜにインストールログなんてものを貼るんだ！
という意見もあるかと思いますが、同じようなことをやってる人が、困ったときとかに検索して引っかかったら、何か役立つかもしれないかなぁ、というのと、同じことをやろうとする人が現れた時に過去の実物を見られると今やってることの妥当性がわかる(こんなにたくさん関連物がインストールされちゃってるけど、これは別に問題ないんだ等)って感じで安心するのに役立つんじゃないかと思って、貼ってます。
自分でいうとエラーが起きたときとか、そのエラーメッセージをそのままgoogleの検索窓にコピペしてすぐに解決策がわかったことが多いし。

あとは、自分の記憶が薄くなったときに、あの時どうやったっけ？と過去検索するときに同様な安心感を得られるかな、と。
