CentOS6.5にて、yumでインストールされるSquidでは、よく変わるtokenなどのクエリ文字列を無視してキャッシュする設定ができなかったので、squid3.5をインストールして設定するためのメモ。httpsだとSquidからURLが見えないので、クライアントからはhttpでアクセスさせ、Squidにてmod_rewriteでhttpsに書き換えてアクセスする設定も含む

squidのインストール・確認に必要なライブラリをインストール

yum install libtool-ltdl
yum install telnet

squidインストール

# yumではsquid最新版はダウンロードできないので、wgetする
cd /tmp/
wget http://www1.ngtech.co.il/repo/centos/6/x86_64/squid-3.5.16-1.el6.x86_64.rpm
tar xvzf squid-3.5.16-1.el6.x86_64.rpm
