Docker ubuntu: install python-PIL-image environment on 14.04

Because there is a need for image analysis in the collection, now that the crawler architecture is deployed in docker, it is necessary to configure an image package in PIL, due to many errors. So record it.

PIL installation

Install dependencies
1.1 ubuntu installation

apt-get install python-dev
apt-get install libjpeg-dev
apt-get install libjpeg8-dev
apt-get install libpng3
apt-get install libfreetype6-dev
ln -s /usr/lib/`uname -i`-linux-gnu/libfreetype.so /usr/lib
ln -s /usr/lib/`uname -i`-linux-gnu/libjpeg.so /usr/lib
ln -s /usr/lib/`uname -i`-linux-gnu/libz.so /usr/lib

sudo apt-get build-dep python-imaging

Since the header file of libfreetype in ubuntu14 is in the /usr/include/freetype2 directory, but the path used in PIL is freetype, you need to do the following

cd /usr/include
ln -s freetype2 freetype

Install PIL library

$:wget wget http://effbot.org/downloads/Imaging-1.1.7.tar.gz 
$:tar -zxvf Imaging-1.1.7 
$:cd Imageing-1.1.7 

Modify setup.py 
JPEG_ROOT ="/usr/local/lib" 
ZLIB_ROOT ="/usr/local/lib" 
FREETYPE_ROOT ="/usr/local/lib"

Check whether the system environment is successfully configured:
$:cd Imaging-1.1.7
$:python setup.py build_ext -i

running build_ext

setup.py script.

To check the build, run the selftest.py script.
As long as JPEG, ZLIB, FREETYPE2 are available
Start the installation of PIL:
