部署

基于本地解释器

默认 uwsgi 基于 python3.6 解析器部署 wsgi 应用，其他python版本需要编译插件
操作：
安装或下载uwsgi 原码，编译 python38 插件

  1. # 源码编译 python3.8
  2. $ ./configure --prefix=/usr/local/python3 --enable-shared --enable-optimizations
  3. $ make altinstall
  5. # 软链接
  6. [root@localhost]# which python
  7. /usr/bin/python
  9. [root@localhost]# which python3
  10. /usr/local/bin/python3
  12. [root@localhost]# ln -s /usr/local/python3/bin/python3.8 /usr/bin/python3
  13. [root@localhost]# ln -s /usr/local/python3/bin/pip3.8 /usr/bin/pip3
  15. [root@localhost]# python --verison
  16. [root@localhost]# pip -V
  18. # 动态库异常
  19. [root@localhost]# python3 --version
  20. python3: error while loading shared libraries: libpython3.8.so.1.0:cannot open shared object file: No such file or directory
  22. [root@localhost]# find / -name libpython3.8.so.1.0
  23. /usr/local/python3/lib/libpython3.8.so.1.0
  25. [root@localhost]# cp /usr/local/python3/lib/libpython3.6m.so.1.0 /usr/lib/
  26. or
  27. [root@localhost]#  cp /usr/local/python3/lib/libpython3.6m.so.1.0 /usr/lib64/
  30. # 编译插件
  31. $ cd  /usr/src/uwsgi
  32. $ make PROFILE=nolang
  33. $ PYTHON=python3.8 uwsgi --build-plugin "plugins/python python38"
  35. $ mkdir -p /usr/lib/uwsgi/plugins
  36. $ cp python38_plugin.so /usr/lib/uwsgi/plugins/
  37. $ uwsgi --plugin python38 ...

测试 uwsgi

  1. $ pkill -9 uwsgi
  2. $ uwsgi --http-socket :5000 --plugin python38 --module wsgi:app  --virtualenv /var/www/pythonmyadmin/myenv/
