CentOS 6.4 安装搭建 Scrapy 0.22 环境

一、安装Python2.7.6

yum -y update

yum groupinstall -y development

yum install -y zlib-dev openssl-devel sqlite-devel bzip2-devel

wget http://www.python.org/ftp/python/2.7.6/Python-2.7.6.tar.xz[/code] 
解压Python2.7.6

tar -xvf Python-2.7.6.tar.xz


进入Python2.7.6目录

cd Python-2.7.6


编译安装Python2.7.6

./configure
make && make altinstall


二、解决Yum不支持Python2.7的问题
将老的Python程序进行备份

mv /usr/bin/python /usr/bin/python2.6.6


建立新的Python链接

ln -s /usr/local/bin/python2.7 /usr/bin/python


修改/usr/bin/yum文件

vi /usr/bin/yum
将第一行的 #!/usr/bin/python 改为 #!/usr/bin/python2.6.6



三、安装setuptools 和 pip
下载setuptools

wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-1.4.2.tar.gz[/code] 
解压setuptools

tar -xvf setuptools-1.4.2.tar.gz


进入setuptools目录

cd setuptools-1.4.2


通过已安装的Python2.7.6安装setuptools

python setup.py install


安装 pip

easy_install pip


curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | python2.7 -


四、安装libxslt-devel支持lxml
yum install libxslt-devel


五、安装Scrapy
pip install scrapy
