本课demo使用redis做消息队列。安装的话就要:

pip install celery[redis]

这节前半节在demo virtualenv, pyenv这些venv的使用

安装：pip install celery[redis]

消息中间件：RabbitMQ/Redis(用redis比RabbitMQ方便)

创建虚拟环境：（1）安装pip install virtualenv

                        创建：virtualenv env4test

                        激活：source env4test/bin/activate

                        退出虚拟环境：deactivate

                       （2）安装pip install virtualenvwrapper

                        改配置：一般在目录ls /usr/local/bin/virtualenvwrapper.sh

                                      vi ~/.zshrc中新增

                        添加完成立即生效：source ~/.zshrc

                        创建：mkvirtualenv env4test

                        退出虚拟环境：deactivate

                        激活：workon env4test

                        workon 列出所有虚拟环境

pyenv通过系统改坏境变量，改变python变量

pip install virtualenvwrapper

echo "source /usr/local/bin/virtualenvwrapper.sh" >> ~/.bashrc

source ~/.bashrc

mkvirtualenv env4mooc

deactivate

workon env4mooc

workon

pip install virtualenv

virtualenv env4mooc

source env4mooc/bin/activate

deactivate
