部署django+vue+nginx+redis+mysql项目踩的坑

部署django+vue+nginx+redis+mysql项目踩的坑

1、ModuleNotFoundError: No module named '_ssl'

编译安装python前，打开Setup.dist中以下几行注释

编辑usr/local/Python-3.9.5/Modules/Setup.dist

SSL=/usr/local/ssl _ssl _ssl.c \-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \-L$(SSL)/lib -lssl -lcrypto

然后再编译安装python

./configure --with-ssl --prefix=/usr/local/python3.9.5make&&make instll

2、运行xadmin报错

File "/root/.virtualenvs/luffy/lib/python3.9/site-packages/xadmin/plugins/importexport.py", line 48, in from import_export.admin import DEFAULT_FORMATS, SKIP_ADMIN_LOG, TMP_STORAGE_CLASSImportError: cannot import name 'DEFAULT_FORMATS' from 'import_export.admin' (/root/.virtualenvs/luffy/lib/python3.9/site-packages/import_export/admin.py)

解决方案：

注释报错行：

/root/.virtualenvs/luffy/lib/python3.9/site-packages/xadmin/plugins/importexport.py

from import_export.admin import DEFAULT_FORMATS, SKIP_ADMIN_LOG, TMP_STORAGE_CLASS

重新导入，添加以下两行：

from import_export.formats.base_formats import DEFAULT_FORMATSfrom import_export.admin import ImportMixin, ImportExportMixinBase

3、ModuleNotFoundError: No module named 'virtualenvwrapper'

安装虚拟环境

pip3 install virtualenvpip3 install virtualenvwrapper

配置变量环境

vim ~/.bashrc

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3export VIRTUALENVWRAPPER_VIRTUALENV=/usr/bin/virtualenvsource /usr/local/python3/bin/virtualenvwrapper.sh

source ~/.bashrc

4、安装uswgi报错

报错1:

报错2：

[root@python01 ~]# pip3 install uwsgiLooking in indexes: uwsgi Downloading (804 kB) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 804.9/804.9 KB 10.6 MB/s eta 0:00:00 Preparing metadata (setup.py) ... error error: subprocess-exited-with-error × python setup.py egg_info did not run successfully. │ exit code: 1 ╰─> [1 lines of output] ERROR: Can not execute `setup.py` since setuptools is not available in the build environment.

解决方案：

安装依赖

yum -y groupinstall "Development tools"yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel psmisc libffi-devel tk-devel pcre-devel

升级pip和setuptools

/usr/local/python3/bin/python3.9 -m pip install --upgrade pippip3 install --upgrade setuptools

再安装

pip3 install uwsgi

5、module 'jwt' has no attribute 'encode'

jwt和PyJWT冲突导致，同时存在jwt和PyJWT模块，import PyJWT导入的还是jwt，解决方法，卸载jwt和PyJWT，然后重新安装PyJWT

pip uninstall jwtpip uninstall PyJWTpip install PyJWT

6、外键序列化报错

Got AttributeError when attempting to get a value for field `orders` on serializer `CourseSectionSerializer`.The serializer field might be named incorrectly and not match any attribute or key on the `RelatedManager` instance.Original exception text was: 'RelatedManager' object has no attribute 'orders'.

当外键是一对多关系，在序列化外键的时候需要加入many = True参数

coursesections = CourseSectionSerializer(many= True)

6、vue的img向后端nginx请求图片失败（未解决）

vue中在本地像远端的nginx请求图片，返回的格式是text/html，前端无法正常展示(nginx转发img的请求，会改变图片的格式？)

使用curl方式，可以正常返回；并且本地img向本地的django直接请求，也可以正常返回；

本地使用aixos向远端nginx请求，也可以正常返回
