mod_evasiveはEPELからインストール出来るみたい
こんにちは＠oko_changです。
mod_evasiveはDos/DDos/brute forceアタックに有効なApacheモジュールですが、EPELから簡単にインストール出来るようなので備忘録としてまとめておきます。
導入手順
EPELリポジトリの追加
# rpm http://ftp.riken.jp/Linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
mod_evasiveのインストール
# yum --enablerepo=epel install mod_evasive
ロックファイルを配置するディレクトリを作成します。
# mkdir /var/lock/mod_evasive # chown apache.apache /var/lock/mod_evasive
少し変えてるけど設定ファイルはデフォルトだとだいたいこんな感じです。
# cat /etc/httpd/conf.d/mod_evasive.conf
LoadModule evasive20_module modules/mod_evasive20.so
<IfModule mod_evasive20.c>
DOSHashTableSize 3097
DOSPageCount 2
DOSSiteCount 50
DOSPageInterval 1
DOSSiteInterval 1
DOSBlockingPeriod 10
DOSLogDir "/var/lock/mod_evasive"
#DOSWhitelist 127.0.0.1
</IfModule>Apacheを再起動して有効化
# service httpd restart

感想
ソースインストールでも簡単だけど、EPELからインストール出来るとさらに簡単なので良い。
