scrapy install

一、安装Python2.7.6

更新CentOS lib库文件

yum -y update

安装开发工具包

yum groupinstall -y development

安装扩展包

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

下载Python2.7.11

wget https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tar.xz

解压Python2.7.11

tar -xvf Python-2.7.11.tar.xz

进入Python2.7.11目录

cd Python-2.7.11

编译安装Python2.7.11

./configure
make && make install

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

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

六、安装MySQL-python
通过yum安装MySQL-python不知道为什么不成功
自己下载安装就可以成功，命令如下

wget http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz/download
tar zxf MySQL-python-1.2.3.tar.gz && cd MySQL-python-1.2.3
python setup.py build
python setup.py install

如果在执行python setup.py build时,报EnvironmentError: mysql_config not found的话,先查找mysql_config的位置,使用find / -name mysql_config,我的是在/usr/local/mysql/bin/mysql_config,然后修改MySQL-python-1.2.3目录下的site.cfg文件,去掉mysql_config=XXX这行的注释,并改成mysql_config=/usr/local/mysql/bin/mysql_config,以自己机器的为准.
再执行下命令就可以了

python setup.py build
python setup.py install

七、安装Pillow
先安装依赖包

sudo yum install libtiff-devel libjpeg-devel libzip-devel freetype-devel lcms2-devel libwebp-devel tcl-devel tk-devel

然后执行

pip install Pillow
