一.準備工作
1.安裝好DM8資料庫
過程略
2.下載下傳DM8相關驅動包
下載下傳位址：産品下載下傳 | 達夢資料庫
3.安裝Django3.1.7版本
過程略
4.python環境：版本3.7.9
過程略
二.驅動安裝
解壓Python-20211220.zip
1.安裝dmPython驅動
cd dmPython
python3 setup.py install
2.安裝django驅動
cd django317/django_dmPython
python3 setup.py install
3.檢查安裝情況
[[email protected] django_dmPython]# python3
Python 3.7.9 (default, Mar 2 2021, 02:43:11)
[GCC 7.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import re
>>> import django
>>> import dmPython
>>> import django_dmPython
>>>
三.Django配置
1.建立項目
django-admin startproject dmtest
2.建立應用
python3 manage.py startapp syscheck
3.修改settings.py檔案
vim dmtest/settings.py
通路主機部分：
ALLOWED_HOSTS = ['*']
應用安裝部分：
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'syscheck',
]
資料庫連接配接部分：
DATABASES = {
'default': {
'ENGINE': 'django_dmPython',
'NAME': 'dmsystest',
'USER': 'dmsystest',
'PASSWORD': 'dameng123',
'HOST': '192.168.163.137',
'PORT': '5237',
'OPTINOS': {'local_code': 1, 'connection_timeout': 5},
}
}
語言顯示部分：
LANGUAGE_CODE = 'zh-Hans'
4.建立資料庫對應關系
vim syscheck/models.py
from django.db import models
class info1(models.Model):
ip_addr = models.CharField(max_length=50, null=True)
sys_name = models.CharField(max_length=50, null=True)
sys_version = models.CharField(max_length=50, null=True)
cpu_type = models.CharField(max_length=50, null=True)
cpu_cores = models.CharField(max_length=50, null=True)
cpu_sockets = models.CharField(max_length=50, null=True)
net_info1 = models.CharField(max_length=50, null=True)
net_info2 = models.CharField(max_length=50, null=True)
# Create your models here.
5.修改views.py檔案，顯示html模闆
vim syscheck/views.py
from django.shortcuts import render
from syscheck.models import info1
import datetime
# Create your views here.
def localinfo(request):
time1=datetime.datetime.now()
infos=info1.objects.all()
return render(request,"test1.html",locals())
6.建立html模闆
mkdir syscheck/templates
vim syscheck/templates/test1.html
{% load static %}
<html >
<head>
<meta charset="UTF-8">
<title>Upload Successfully</title>
</head>
<body style="background-image: url({% static '2.jpg' %});background-size:100% 133.5%;" >
<p style="color:WhiteSmoke">系統資訊</p>
<p style="color:WhiteSmoke">伺服器時間：{{ time1 }}</p>
<br>
{% for i in infos %}
<p style="color:seagreen;">{{i.ip_addr}}</p>
<p style="color:MediumSlateBlue;">系統名稱: {{i.sys_name}}</p>
<p style="color:MediumSlateBlue;">系統版本: {{i.sys_version}}</p>
<br>
<br>
{% endfor %}
</body>
</html>
7.修改urls檔案
vim dmtest/urls.py
from django.contrib import admin
from django.urls import path
from syscheck import views
urlpatterns = [
path('admin/', admin.site.urls),
path('sysinfo/',views.localinfo),
]
8.添加靜态圖檔背景
mkdir static
拷貝2.jpg檔案至static目錄下
修改settings.py檔案
STATIC_URL = '/static/'
STATICFILES_DIRS = [
os.path.join(BASE_DIR, "static"),
]
9.同步資料
python3 manage.py makemigrations
python3 manage.py migrate
四.使用python處理文本檔案，往DM8資料庫插入資料
文本如圖：
python程式：
import re
import dmPython
#定義空清單
list_local_sysinfo=[]
#讀取檔案，将每行的值存入清單
with open(r'/opt/web/produce/python/system_check_.tmp', 'r', encoding='UTF-8') as f:
for line in f:
m=re.search('：.*\n|:.*\n',line)
#print(m)
if (m != None):
(m1,m2) = re.search('：.*\n|:.*\n',line).span()
m3=line[m1+1:m2-1]
#print(m3)
list_local_sysinfo.append(m3)
#print(list_local_sysinfo)
#從清單中給變量指派，友善知道往資料庫裡存入的資料是什麼
sys_name = list_local_sysinfo[0]
sys_version = list_local_sysinfo[1]
net_exter = list_local_sysinfo[2]
net_inter = list_local_sysinfo[3]
cpu_type = list_local_sysinfo[4]
cpu_cores = list_local_sysinfo[5]
cpu_frequency = list_local_sysinfo[6]
cpu_threads_percore = list_local_sysinfo[7]
cpu_cores_persocket = list_local_sysinfo[8]
cpu_sockets = list_local_sysinfo[9]
memory = list_local_sysinfo[10]
sys_disk = list_local_sysinfo[11]
nums_lun = list_local_sysinfo[12]
java_version = list_local_sysinfo[13]
'''
print(
sys_name,'\n',sys_version,'\n',net_exter ,'\n',net_inter ,'\n',cpu_type ,'\n',cpu_cores ,'\n',cpu_frequency ,'\n',
cpu_threads_percore ,'\n',cpu_cores_persocket ,'\n',cpu_sockets ,'\n',memory ,'\n',sys_disk ,'\n',nums_lun ,'\n',
java_version ,'\n'
)
'''
#調用dmPython接口，插入資料
try:
conn = dmPython.connect(user='dmsystest', password='dameng123', server='192.168.163.137', port=5237)
cursor = conn.cursor()
try:
#清空表，初始化測試環境
cursor.execute ('delete from t_syscheck')
except (dmPython.Error, Exception) as err:
null
try:
#插入資料
cursor.execute ("insert into t_syscheck values('192.168.163.136',?,?,?,?,?,?,?,?,?,?,?,?,?,?)",
sys_name,sys_version,net_exter,net_inter,cpu_type,cpu_cores,cpu_frequency,
cpu_threads_percore,cpu_cores_persocket,cpu_sockets,memory,sys_disk,nums_lun,java_version)
print('python: insert success!')
except (dmPython.Error, Exception) as err:
print(err)
cursor.close()
conn.close()
except (dmPython.Error, Exception) as err:
print(err)
五.運作網站
