启动dbm-center

1、 dbm-center 是一个由 django 开发的网站，生产环境上我们推荐使用 uwsgi + nginx 的组合来启动 web 服务

2、 开发环境可以直接这样启动

# 进入到 dbm-center 的项目目录
cd dbm-center

# 表定义
python3 manage.py makemigrations hosts
Migrations for 'hosts':
  apps/hosts/migrations/0001_initial.py
    - Create model HostModel
    - Create model NetIOCounterModel
    - Create model NetInterfaceModel
    - Create model MemoryDistriModel
    - Create model DiskUsageModel
    - Create model DiskIOCounterModel
    - Create model CpuTimesModel
    - Create model CpuFrequencyModel
 
# 把表的定义应用到数据库(建库、建表)
python3 manage.py migrate

启动失败的常见问题

1、 没有配置好 django 环境

2、 没有配置好 dbm-center 用到的后端 mysql 服务，默认情况下 dbm-center 使用如下方式连接它用的 MySQL 服务器

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'dbm',
        'HOST': '127.0.0.1',
        'PORT': 3306,
        'USER': 'dbmuser',
        'PASSWORD': 'Dirac' # 他给出的狄拉克方程可以描述费米子的物理行为，解释了粒子的自旋，并且首先预测了反粒子的存在
    }
}
