pip install -r requirements.txt
or
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple -r requirements.txt

安装打包所需的Python环境

如果要通过共享库的方式安装 python, 可使用如下命令:

1	env PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.8.6

上述为了避免打包时出现 “找到libpython3.7.so.1.0等库文件”

OSError: Python library not found: libpython3.7.so.1.0, libpython3.7m.so.1.0, libpython3.7mu.so.1.0

This would mean your Python installation doesn't come with proper library files.
This usually happens by missing development package, or unsuitable build parameters of Python installation.

* On Debian/Ubuntu, you would need to install Python development packages
  * apt-get install python3-dev
  * apt-get install python-dev
* If you're building Python by yourself, please rebuild your Python with `--enable-shared` (or, `--enable-framework` on Darwin)

解决思路（一）
先检索以下系统中是否已有这几个文件：libpython3.7.so.1.0, libpython3.7m.so.1.0, libpython3.7mu.so.1.0

1	find / -name libpython*

出现了错误：

1 2	find: paths must precede expression: libpython3.8.so Usage: find [-H] [-L] [-P] [-Olevel] [-D help\|tree\|search\|stat\|rates\|opt\|exec] [path...] [expression]

然后就上网查了一下,结果搜索到一篇,大概是这样说的:多文件的查找的时候需要增加单引号,修改后:

1	find / -name 'libpython*'

解决思路（二）
重新编译python解释器，增加—enable-shared选项
要重装Python，进入到Python文件使用

1	./configure --prefix=/usr/local/python3 --enable-shared --with-openssl=/usr/local/openssl

然后 make && make install就好了
现在再次打开python的时候，会报错，
ImportError: libpython3.7m.so.1.0: cannot open shared object file: No such file or directory
需要依次执行
echo "/usr/local/python3/lib/" >> /etc/ld.so.conf
ldconfig

解决思路（三）
安装python3-devel-3.7的包。Debian/Ubuntu下包名为python3-dev，Centos下包名为python3-devel，注意选择3.7的版本。CentOS7的环境中基本上只能选择通过外网yum安装，因为CentOS7 Everything的ISO镜像源中提供的版本最高是3.6，而这个包的依赖层又非常多。

yum install python3-devel
or
yum install python*
or
pip3 install python3-dev

重新打包编译了python解释器，然后再执行以下, 将编译的依赖库拷贝到系统库中，

1	cp libpython3.so libpython3.8.so.1.0 /usr/lib64/

项目打包

下载 Pyinstaller

1	pip install pyinstaller

制作项目的.spec文件
进入django项目所在路径，运行

1	pyi-makespec -D manage.py

以文本的方式打开.spec文件，spec文件格式如下。

# -*- mode: python ; coding: utf-8 -*-


block_cipher = None


a = Analysis(
    ['manage.py'],
    pathex=['/opt/cdpadmin'],
    binaries=[],
    datas=[],
    hiddenimports=[
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'cdpapp',
    'django_crontab',
    'django_apscheduler',
    'django.template.context_processors',
    'django.contrib.auth.context_processors',
    'django.contrib.messages.context_processors',
    'django.middleware.security',
    'django.contrib.sessions.middleware',
    'django.middleware.common',
    'django.middleware.csrf',
    'django.contrib.auth.middleware',
    'django.contrib.messages.middleware',
    'django.middleware',
    'django.db.backends'
    ],
    hookspath=[],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    win_no_prefer_redirects=False,
    win_private_assemblies=False,
    cipher=block_cipher,
    noarchive=False,
)
pyz = PYZ(a.pure, a.zipped_data, cipher=block_cipher)

exe = EXE(
    pyz,
    a.scripts,
    [],
    exclude_binaries=True,
    name='manage',
    debug=False,
    bootloader_ignore_signals=False,
    strip=False,
    upx=True,
    console=True,
    disable_windowed_traceback=False,
    argv_emulation=False,
    target_arch=None,
    codesign_identity=None,
    entitlements_file=None,
)
coll = COLLECT(
    exe,
    a.binaries,
    a.zipfiles,
    a.datas,
    strip=False,
    upx=True,
    upx_exclude=[],
    name='manage',
)

一切准备好后，执行下面语句就OK

1	pyinstaller manage.spec

打包后在dist->manage文件中如下图所示
在这里插入图片描述
若需要导出mysql数据库信息

1	mysqldump -uroot -pgbnc2012 --all-databases > /root/hyb_cdp.sql

将django项目打包，执行以下命令行

1	vim /root/pyinstaller_hyb.sh

rm /opt/cdpadmin/dist/manage -rf
cp /root/manage.spec /opt/cdpadmin/manage.spec
pyinstaller manage.spec
cp -dRp /opt/cdpadmin/cdpapp/* /opt/cdpadmin/dist/manage/cdpapp/

rm /opt/cdpadmin/statics -rf
python3 manage.py collectstatic

cp -dRp /opt/cdpadmin/statics /opt/cdpadmin/dist/manage/

cp -dRp /root/installpath/ /opt/cdpadmin/dist/manage/

cd /opt/cdpadmin/dist/
mv ./manage ./cdpadmin
tar -czvf hyb_cdp_v1.0.tar.gz cdpadmin
cp /opt/cdpadmin/dist/hyb_cdp_v1.0.tar.gz /root/hyb_cdp_v1.0.tar.gz

rm -rf /opt/cdpadmin/dist/
rm -rf /opt/cdpadmin/build/
rm -rf /opt/cdpadmin/manage.spec
