Python Tomcat Script(多实例)

之前书写过 Tomcat 单实例的 Python 脚本,本次增加 Tomcat 多实例的操作脚本.

1:准备

　　安装所需 Python 插件
　　　　A方法: pip install argparse

　　　　B方法:1.安装依赖包{setuptools}

　　　　　　　2.安装 argparse

#tar xzf setuptools-19.1.1.tar.gz && cd setuptools-19.1.1 && python setup.py install
#tar xzf argparse-1.4.0.tar.gz && cd argparse-1.4.0 && python setup.py install
