python企业实战项目模拟上线

注意：
１．项目下载地址：https://github.com/blackmed/python-xingdian.git
２．本项目运行的环境centos7操作系统
３．python3.5.2的下载地址：https://github.com/blackmed/xingdian-python3.5.2.git

一：部署
１．安装pyenv
下载地址：https://github.com/pyenv/pyenv
把项目下载到本地，直接下载到：~.pyenv

[root@xingdian ~]#　git clone https://github.com/pyenv/pyenv.git ~/.pyenv

２．设置环境变量

[root@xingdian ~]# echo 'export PYENV_ROOT="$HOME/.pyenv"' >> /etc/profile
[root@xingdian ~]# echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> /etc/profile
[root@xingdian ~]# echo 'eval "$(pyenv init -)"'　>> /etc/profile
[root@xingdian ~]# source /etc/profile

３．根据项目所需要的python环境安装对应版本的python

[root@xingdian ~]# pyenv install 3.5.2

４．切换到项目目录下，使对应版本的python生效

[root@xingdian izone]#　pyenv local 3.5.2

５．根据开发需求写好的requirements.txt文件，安装相应的模块

[root@xingdian izone]# pip install -r requirements.txt

6.安装项目所需的redis

[root@xingdian ~]# yum -y install redis
[root@xingdian ~]# sed -i '/^protected-mode/c protected-mode no' /etc/redis.conf
[root@xingdian ~]# sed -i '/^bind 127.0.0.1/c #bind 127.0.0.1' /etc/redis.conf
[root@xingdian ~]# systemctl start redis

７．安装数据库服务（暂定mariadb）

[root@xingdian ~]# yum -y install mariadb mariadb-server
[root@xingdian ~]# systemctl start mariadb
[root@xingdian ~]# mysqladmin -u root password '123'
[root@xingdian ~]# mysql -u root -p123
mysql> create database  myzone;

８．项目中跟数据库和redis的连接文件［项目中已修改］

cat izone/settings.py
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME':'myzone',
        "HOST":'127.0.0.1',
        "POST":3306,
        "USER":'root',
        "PASSWORD":'123'
    }
}
CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379/1",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
        }
    }
}

９．数据迁移

[root@xingdian ~]#　python manage.py makemigrations --empty myzone
[root@xingdian ~]#　python manage.py migrate

１０．运行项目

[root@xingdian ~]#　python manage.py runserver
