python寫的批量操作遠程主機腳本(命令執行,上傳、下載文件)

最近在學習python，藉助fabric模塊寫了個批量操作服務器的腳本，在此分享給大家，如有不足之處，歡迎大家指正

準備工作：

安裝python 2.6.5:

yum -y install readline*

tar xf Python-2.6.5.tar.bz2

cd Python-2.6.5

將目錄下Modules/Setup.dist文件中"readline readline.c -lreadline -ltermcap"行前的註釋去掉

編譯安裝：

./configure --enable-shared

make -j8 && make install

安裝setuptools

tar xf setuptools-0.6c11.tar.gz

cd setuptools-0.6c11

python setup.py install

安裝fabric

執行安裝時，軟件會自動從網上查找依賴的安裝包並進行安裝

tar xf fabric-0.9rc2.tar.gz

cd goosemo-fabric-1eacbf2

python setup.py install
