Linux學習8-CentOS部署自己本地的django項目

前言

自己本地寫好的django項目，如何部署到linux服務器上,讓其他的小伙伴也能訪問呢？本篇以centos系統為例，把本地寫好的django項目部署到linux服務器上
環境准備：

環境准備：
1.一台Linux服務器, 操作系統： CentOS 7.4 64位
2.python3.6 （前面已經搭建好）
3.django-2.1.4

django環境准備

前面已經安裝好了python3.6.8的環境並且pip也配置好了，安裝django直接用pip安裝就可以了,安裝的django版本位django-2.1.4

pip install django

[root@yoyo ~]# pip -V
pip 18.1 from /usr/local/python3/lib/python3.6/site-packages/pip (python 3.6)
[root@yoyo ~]# pip install django

django項目代碼

linux服務器上的django環境已經准備好了，接下來就是把在本地電腦已經調通的django項目代碼全部復制到服務器上的某個目錄下
如下圖，通過xftp工具把本地項目代碼全部傳到/opt/helloworld目錄下，前提是在本地瀏覽器測試沒問題了。

啟動django

打開到helloworld目錄，啟動服務：python manage.py runserver

[root@yoyo ~]# cd /opt/helloworld/
[root@yoyo helloworld]# python manage.py runserver

You have 18 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, hello, sessions.
Run 'python manage.py migrate' to apply them.

Django version 2.1.4, using settings 'helloworld.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

由於這個是搭建在服務器上的，所以只能本機訪問：http://127.0.0.1:8000/，可以用python代碼驗證下

[root@yoyo ~]# python
Python 3.6.8 (default, Jan  2 2019, 16:43:17) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import requests
>>> r = requests.get("http://127.0.0.1:8000/")
>>> r.status
>>> r.status_code
200
>>> 

接下來登錄阿里雲ECS后台-安全組-配置規則-開放8000端口，在瀏覽器上輸入http://47.104.xx.xx:8000/發現無法訪問

外網訪問django

如果啟動方式是 python manage.py runserver默認只能本機訪問，為了放開訪問權限，讓其他人也能訪問到這台機器，需加參數0.0.0.0:端口

python manage.py runserver 0.0.0.0:8000

^C[root@yoyo helloworld]# python manage.py runserver 0.0.0.0:8000

Django version 2.1.4, using settings 'helloworld.settings'
Starting development server at http://0.0.0.0:8000/
Quit the server with CONTROL-C.
Invalid HTTP_HOST header: '47.104.x.x:8000'. You may need to add '47.104.x.x' to ALLOWED_HOSTS.
Bad Request: /
[04/Jan/2019 09:57:20] "GET / HTTP/1.1" 400 59588

啟動服務后在瀏覽器輸入：http://47.104.x.x:8000/ ，會報錯‘Invalid HTTP_HOST header: '47.104.x.x:8000'. You may need to add '47.104.x.x' to ALLOWED_HOSTS.’

關閉debug，設置ALLOWED_HOSTS

打開helloworld/settings.py文件，找到這2行代碼

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = True

ALLOWED_HOSTS = []

關閉debug調試功能，ALLOWED_HOSTS設置為全部

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = False

ALLOWED_HOSTS = ["*"]

修改完成后保存下，重啟django服務

python manage.py runserver 0.0.0.0:8000

接着在本地瀏覽器上訪問，就能正常的打開頁面了

到這里一個簡單的django的demo項目就已經成功的部署到linux服務器上了，於是就可以通知你的小伙伴看你做的網站咯~
