1.setting.py檔案，修改資料存儲方式
說明：注釋sqlite3資料庫，改用mysql連接配接
DATABASES = {
"default": {
"ENGINE": "django.db.backends.mysql",
"NAME": "cmdb",
"USER": "root",
"PASSWORD": "root",
"HOST": "127.0.0.1",
"PORT": "3306",
}
} 
2.安裝mysql，建立庫cmdb資料庫
指令：yum install -y mysql-server
3.删除原來sqlite檔案、安裝mysql子產品檔案
指令：rm -rf db.sqlite3
yum list|grep MySQL-python
yum install -y MySQL-python.x86_64
4.使用管理腳本，同步資料庫
python manage.py validate
python manage.py syncdb
5.修改hostinfo目錄下，修改views.py檔案，檢視啟動屬性
6.啟動伺服器，和收集腳本
python manage.py runserver 0.0.0.0:8000
python getHostInfo.py
7.修改收集資訊腳本，将資訊序列化記憶體中，執行腳本，序列化，檢視列印資訊
執行收集腳本，結果：
8.反序列化，修改views.py
執行收集腳本，運作結果：
9.修改資訊收集腳本，執行個體化
