wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz

tar zxvf setuptools-0.6c11.tar.gz

cd setuptools-0.6c11

python setup.py build

python setup.py install

===============================以上为先安装Python安装模块，然后

下载pip的tar.gz包并安装

tar; cd; python setup.py install;

然后安装ngxtop,直接运行下面的即可，(有时需要先更新pip，用命令pip install --upgrade pip)

pip install ngxtop
