python网页运行环境_arm平台 python web运行环境

1、安装zlib源码包

下载zlib源码包

http://www.zlib.net/

tar -zxf zlib-1.2.11.tar.gz

cd zlib-1.2.11/

# 使用你自己的编译环境

CC=arm-hisiv400-linux-gcc

AR=arm-hisiv400-linux-ar

RANLIB=arm-hisiv400-linux-ranlib

# 安装至你的交编译器所在的环境目录

./configure –prefix=/opt/hisi-linux/x86-arm/arm-hisiv400-linux/arm-hisiv400-linux-gnueabi –shared

make;

make install;

make install –prefix=/opt/zlib

2、安装sqlite3

安装sqlite3

wget https://www.sqlite.org/2018/sqlite-autoconf-3250200.tar.gz

tar -zxvf sqlite-autoconf-3250200.tar.gz

cd sqlite-autoconf-3250200

./configure CC=arm-hisiv400-linux-gcc AR=arm-hisiv400-linux-ar RANLIB=arm-hisiv400-linux-ranlib LDFLAGS=-lrt READELF=arm-hisiv400-linux-readeif CPP=arm-hisiv400-linux-cpp –host=arm-hisiv400-linux-gnueabi –build=x86_64-linux-gnu –prefix=/opt/sqlite3

make;make install;

3、安装python3

安装python3

修改setup.py文件以支持sqlite3

# 第1138行修改为

1137 if cross_compiling:

1138 sqlite_inc_paths = [‘/opt/sqlite3/include’]

修改Modules/Setup文件以支持zlib

# 365行修改为

365 zlib zlibmodule.c -I/opt/zlib/include -L/opt/zlib/lib -lz

但是用修改Modules/Setup文件方式构建的zlib仅是 build-in 方式

在python3/lib/python3.6/lib-dynload 中并没有生成对应的.so文件

因此虽然在python shell中可以正常导入zlib

但是使用uwsgi运行应用时仍会出现找不到zlib

因此需要更换构建方式

通过阅读setup.py

1402

1403 # Andrew Kuchling’s zlib module. Note that some versions of zlib

1404 # 1.1.3 have security problems. See CERT Advisory CA-2002-07:

1405 # http://www.cert.org/advisories/CA-2002-07.html

1406 #

1407 # zlib 1.1.4 is fixed, but at least one vendor (RedHat) has decided to

1408 # patch its zlib 1.1.3 package instead of upgrading to 1.1.4. For

1409 # now, we still accept 1.1.3, because we think it’s difficult to

1410 # exploit this in Python, and we’d rather make it RedHat’s problem

1411 # than our problem .

1412 #

1413 # You can upgrade zlib to version 1.1.4 yourself by going to

1414 # http://www.gzip.org/zlib/

1415 zlib_inc = find_file(‘zlib.h’, [], inc_dirs)

1416 have_zlib = False

1417 if zlib_inc is not None:

1418 zlib_h = zlib_inc[0] + ‘/zlib.h’

1419 version = ‘”0.0.0″‘

1420 version_req = ‘”1.1.3″‘

发现安装时会寻找zlib所在头文件，而目录集则在inc_dirs这个变量中

通过打印inc_dirs得知

[‘./Include’, ‘/opt/python3/include’, ‘.’, ‘/opt/hisi-linux/x86-arm/arm-hisiv400-linux/bin/../target/usr/include’, ‘/home/nsk/bin/Python-3.6.0/Include’, ‘/home/nsk/bin/Python-3.6.0’]

发现会在以上几个目录寻找头文件，然而之前编译zlib存放的位置是

/opt/hisi-linux/x86-arm/arm-hisiv400-linux/arm-hisiv400-linux-gnueabi

并没有出现在上述列表中，于是将/opt/zlib include 和 lib 下的文件拷贝到对应的/opt/hisi-linux/x86-arm/arm-hisiv400-linux/bin/…/target/usr/ 的 include 和 lib中并取消修改

# 365行取消修改或者注释

# 365 zlib zlibmodule.c -I/opt/zlib/include -L/opt/zlib/lib -lz

通过上述修改后，当编译时会自动生成编译zlib的指令

tar -zxf Python-3.6.0.tgz

cd Python-3.6.0/

echo ac_cv_file__dev_ptmx=no > config.site

echo ac_cv_file__dev_ptc=no >> config.site

export CONFIG_SITE=config.site

make -j8;

make install -j8;

编译完成后可通过查看build/lib.linux-arm-3.6目录

确认 zlib.cpython-36m-arm-linux-gnueabi.so 文件存在

4、安装pycrypto

安装pycrypto

tar -zxf pycrypto-2.6.1\ \(1\).tar.gz

cd pycrypto-2.6.1

python3 setup.py install –prefix=/opt/python3

可能出错

运行过程中如果出现使用了默认gcc的情况，使用

cd /usr/bin

mv gcc gcc_bak

ln -s /opt/hisi-linux/x86-arm/arm-hisiv400-linux/bin/arm-hisiv400-linux-gnueabi-gcc ./gcc

5、安装psutil

安装psutil

tar -zxf psutil-5.6.3\ \(1\).tar.gz

cd psutil-5.6.3/

python3 setup.py install –prefix=/opt/python3

出错

TEST FAILED: /opt/python3/lib/python3.6/site-packages/ does NOT support .pth files

error: bad install directory or PYTHONPATH

You are attempting to install a package to a directory that is not

on PYTHONPATH and which Python does not read “.pth” files from. The

installation directory you specified (via –install-dir, –prefix, or

the distutils default setting) was:

/opt/python3/lib/python3.6/site-packages/

and your PYTHONPATH environment variable currently contains:

‘/opt/arm_python/lib/python3.6/site-packages’

Here are some of your options for correcting the problem:

修改python path

export PYTHONPATH=/opt/python3/lib/python3.6/site-packages

出现使用默认gcc的情况解决方式同上

6、安装uwsgi

安装pcre

http://www.pcre.org/

# 编译arm版

tar zxvf pcre-8.0.0.tar.gz

cd pcre-8.0.0

./configure CC=arm-hisiv400-linux-gcc –host=arm-hisiv400-linux-gnueabi –prefix=/opt/pcre –disable-cp

make;

make install;

# 编译x86版

make clean;

./configure –disable-cp;

make;

make install;

# pcre-config –version

8.00

安装uwsgi

tar -zxf uwsgi-2.0.18.tar.gz

cd uwsgi-2.0.18

python3 setup.py install –prefix=/opt/python3

出错

/usr/local/lib/python3.6/config-3.6m-x86_64-linux-gnu/libpython3.6m.a: error adding symbols: 不可识别的文件格式

默认使用了host的python3环境，所以需要修改为arm python3的环境

修改uwsgiconfig.py文件可能有更好的方法

# 在594行下面添加

libs[-3] = ‘/opt/python3/lib/python3.6/config-3.6m-arm-linux-gnueabi/libpython3.6m.a’

再次执行

python3 setup.py install –prefix=/opt/python3

出错

/home/nsk/bin/Python-3.6.0/Python/pytime.c:567: undefined reference to `clock_gettime’

编译命令需要添加 -lrt

继续修改uwsgiconfig.py文件

594 print(“*** uWSGI linking ***”)

# 添加：

595 print(libs)

596 libs[-3] = ‘/opt/python3/lib/python3.6/config-3.6m-arm-linux-gnueabi/libpython3.6m.a’

# 确保本地也安装pcre 需要本地程序触发指令才能生成pcre的编译命令

597 libs[5] = ‘-L/opt/pcre/lib -lpcre’

598 libs.append(‘-lrt’)

7、安装setuptools

安装setuptools

tar -zxf setuptools-28.8.0.tar.gz

cd setuptools-28.8.0/

python3 setup.py install –prefix=/opt/python3

8、安装pip

安装pip

tar -zxf pip-9.0.1.tar.gz

cd pip-9.0.1/

python3 setup.py install –prefix=/opt/python3

9、安装six

安装six

tar -zxf six-1.14.0\ \(1\).tar.gz

cd six-1.14.0/

python3 setup.py install –prefix=/opt/python3

10、安装 pytz

安装 pytz

tar -zxf pytz-2019.3\ \(1\).tar.gz

cd pytz-2019.3/

python3 setup.py install –prefix=/opt/python3

11、安装django

安装django

tar -zxf Django-2.1.8.tar.gz

cd Django-2.1.8/

python3 setup.py install –prefix=/opt/python3

12、环境

不连接公网web端程序，不考虑高并发访问和数据存储问题，因此消息队列和大型数据库之类的并不需要

最后将/opt/python3 整个目录拷贝至arm上

将 /opt/sqlit3/lib 与 bin 分别拷贝到 arm系统中 /usr/bin 和 /usr/lib 或者拷贝到其他位置添加环境变量

将 /opt/pcre/lib 与 bin 分别拷贝到 arm系统中 /usr/bin 和 /usr/lib 或者拷贝到其他位置添加环境变量

将 /opt/zlib/lib 与 bin 分别拷贝到 arm系统中 /usr/bin 和 /usr/lib 或者拷贝到其他位置添加环境变量

项目运行出错 ImportError: cannot import name ‘_AES’

在/mnt/python3/lib/python3.6/site-packages/Crypto/Cipher/新建 _AES.py

内容：

# encoding: utf-8

# module Crypto.Cipher._AES

# by generator 1.145

# no doc

# Variables with simple values

block_size = 16

key_size = 0

MODE_CBC = 2

MODE_CFB = 3

MODE_CTR = 6

MODE_ECB = 1

MODE_OFB = 5

MODE_PGP = 4

# functions

def new(key, mode=None, *args, **kwargs): # real signature unknown; NOTE: unreliably restored from __doc__

“”” new(key, [mode], [IV]): Return a new _AES encryption object. “””

pass

# no classes

# variables with complex values

__loader__ = None # (!) real value is ”

__spec__ = None # (!) real value is ”

uwsgi运行出现Bind(): “Cannot assign requested address”

执行

ifconfig lo up
