LVSの3種類の負荷等化技術のテスト

34391 ワード
LVS 負荷バランス
テスト前にipvsadmインストールをインストールする前に、インストール依存性が必要です.
yum install kernel-devel gcc openssl openssl-devel popt

公式サイトへhttp://www.linuxvirtualserver.org】ipvsadmをダウンロードする際には、サーバカーネルバージョンの表示に注意する必要があります.
サーバカーネルのバージョンを問い合わせるには、次の手順に従います.
rpm -q kernel-devel

サーバカーネルバージョンに基づいてipvsadmを選択してダウンロードしてインストール
tar -xvf ipvsadm-x.xx.tar.gz

cd ipvsadm-x.xx

make && make install
