クラスタ内の複数ノード間でファイルを同期させるための同期スクリプトを作成し、各ターゲットノードの同一ディレクトリにファイルを循環的に同期します(root権限を持つユーザー、またはrootユーザーでxsyncを作成する必要があります)
1.sudoでxsyncファイルを作成(rootユーザーは直接作成可能)
xsyncスクリプトのソースコード:
#!/bin/bash
#1. パラメータ数の確認
if [ $# -lt 1 ]
then
echo 引数が不足しています!
exit;
fi
#2. クラスタ内のすべてのマシンを反復処理
for server in primary worker1 worker2
do
echo ==================== $server ====================
#3. すべてのディレクトリを反復処理し、それぞれを送信
for item in $@
do
#4. ファイルの存在確認
if [ -e $item ]
then
#5. 親ディレクトリの取得
parent_dir=$(cd -P $(dirname $item); pwd)
#6. 現在のファイル名の取得
file_name=$(basename $item)
ssh $server "mkdir -p $parent_dir"
rsync -av $parent_dir/$file_name $server:$parent_dir
else
echo $item は存在しません!
fi
done
done
yum install -y rsync
xsyncファイルに実行権限を付与:
chmod 777 xsync
- 注意点:
- 1.各ノードにrsyncツールがインストールされ、起動されていることを確認
例:primaryマシンの/optディレクトリにあるscpをworker1とworker2に複製
