1：首先創建一個django項目

[root@localhost opt]# django-admin startproject ops
CommandError: '/opt/ops' already exists
[root@localhost opt]# cd ops
[root@localhost ops]# tree
.
├── manage.py
└── ops
? ?├── __init__.py
? ?├── settings.py
? ?├── urls.py
? ?└── wsgi.py

1 directory, 5 files
[root@localhost ops]#

2：繼續創建一個APP

[root@localhost ops]# django-admin startapp polls
[root@localhost ops]# tree
.
├── manage.py
├── ops
│ ? ├── __init__.py
│ ? ├── settings.py
│ ? ├── urls.py
│ ? └── wsgi.py
└── polls
? ?├── admin.py
? ?├── apps.py
? ?├── __init__.py
? ?├── migrations
? ?│ ? └── __init__.py
? ?├── models.py
? ?├── tests.py
? ?└── views.py

3 directories, 12 files
這里要注意下settings.py是全局的配置，即項目下的所有全局配置都在這里，下面要說的urls.py也類似

3：配置全局的setting文件

Django?settings?for?ops?project.

Generated?by?'django-admin?startproject'?using?Django?1.11.

4: 啟用urls.py

urlpatterns?=?[
????url(r'^admin/',?admin.site.urls),
]

5: APP下的models

#?-*-?coding:?utf-8?-*-

from?__future__?import?unicode_literals

from?django.db?import?models

#?Create?your?models?here.
class?ServerList(models.Model):
????hostname=models.CharField(max_length=50,verbose_name=u'主機名')
????user=models.CharField(max_length=50,verbose_name=u'使用人')
????brand=models.CharField(max_length=50,verbose_name=u'品牌')
????sn=models.CharField(max_length=50,verbose_name=u'SN')
????mac=models.CharField(max_length=50,blank=True,null=True,verbose_name=u'MAC地
址')
????os=models.CharField(max_length=50,verbose_name=u'系統版本')
????cpu=models.CharField(max_length=50,verbose_name=u'CPU')
????memory=models.CharField(max_length=50,verbose_name=u'內存')
????desk=models.CharField(max_length=50,verbose_name=u'硬盤')
????status=models.CharField(blank=True,null=True,verbose_name=u'狀態')
????remark=models.CharField(blank=True,null=True,verbose_name=u'注釋')
????dept=models.CharField(max_length=50,verbose_name=u'部門')

????def?__unicode__(self):
????????return?u'%s?%s?%s?%s?%s?%s?%s?%s?%s?%s?%s?%s'?%(self.hostname,self.dept,self.user,self.brand,self.os,self.cpu,self.memory,self.desk,self.mac,self.sn,self.status,self.remark)

6: APP下的admin.py

#?-*-?coding:?utf-8?-*-
from?__future__?import?unicode_literals

from?django.contrib?import?admin
from?polls.models?import?ServerList
class?TitleList(admin.ModelAdmin):
????list_display?=?('hostname','user','brand','sn','mac','os','cpu','memory','desk','status','remark','dept')
????search_fields?=?('hostname','user','brand','sn','mac','os','cpu','memory','desk','status','remark','dept')
admin.site.register(ServerList,TitleList)

7：創建數據庫并賦予權限（安裝mysql的過程就不詳細介紹）

mysql>?CREATE?DATABASE?`ops`?/*!40100?DEFAULT?CHARACTER?SET?utf8?*/;
Query?OK,?1?row?affected?(0.00?sec)

mysql>?GRANT?ALL?PRIVILEGES?ON?`ops`.*?TO?'ops'@'localhost'?identified?by?'ops';
Query?OK,?0?rows?affected?(0.06?sec)

mysql>

8：同步數據庫

[root@localhost?ops]#?python?manage.py?makemigrations?polls
Migrations?for?'polls':
??polls/migrations/0001_initial.py
????-?Create?model?ServerList
[root@localhost?ops]#?python?manage.py?migrate?polls
Operations?to?perform:
??Apply?all?migrations:?polls
Running?migrations:
??Applying?polls.0001_initial...?OK

9:?

[root@localhost?ops]#?python?manage.py?createsuperuser
Username?(leave?blank?to?use?'root'):
Email?address:?mail@mail.com
Password:
Password?(again):

10：打開站點進入127.0.0.1/admin，使用剛才創建的用戶登錄
