[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：继续创建一个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
这里要注意下settings.py是全局的配置，即项目下的所有全局配置都在这里，下面要说的urls.py也类似
3：配置全局的setting文件
Django settings for ops project.

4: 启用urls.py
from django.conf.urls import url
from django.contrib import admin
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'主机名')
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'系统版本')
cpu=models.CharField(max_length=50,verbose_name=u'CPU')
memory=models.CharField(max_length=50,verbose_name=u'内存')
desk=models.CharField(max_length=50,verbose_name=u'硬盘')
status=models.CharField(blank=True,null=True,verbose_name=u'状态')
remark=models.CharField(blank=True,null=True,verbose_name=u'注释')
dept=models.CharField(max_length=50,verbose_name=u'部门')
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：创建数据库并赋予权限（安装mysql的过程就不详细介绍）
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：同步数据库
[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：打开站点进入127.0.0.1/admin，使用刚才创建的用户登录
