Linux学习django-CentOS部署自己本地的django项目

前言

自己本地写好的django项目，如何部署到linux服务器上,让其他的小伙伴也能访问呢？本篇以centos系统为例，把本地写好的django项目部署到linux服务器上
环境准备：

环境准备：
1.一台Linux服务器, 操作系统： CentOS 7.4 64位
2.python3.6 （前面已经搭建好）
3.django-2.1.4

django环境准备

前面已经安装好了python3.6.8的环境并且pip也配置好了，安装django直接用pip安装就可以了,安装的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项目代码

linux服务器上的django环境已经准备好了，接下来就是把在本地电脑已经调通的django项目代码全部复制到服务器上的某个目录下
如下图，通过xftp工具把本地项目代码全部传到/opt/helloworld目录下，前提是在本地浏览器测试没问题了。

启动django

打开到helloworld目录，启动服务：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.

由于这个是搭建在服务器上的，所以只能本机访问：http://127.0.0.1:8000/，可以用python代码验证下

[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
>>> 

接下来登录阿里云ECS后台-安全组-配置规则-开放8000端口，在浏览器上输入http://47.104.xx.xx:8000/发现无法访问

外网访问django

如果启动方式是 python manage.py runserver默认只能本机访问，为了放开访问权限，让其他人也能访问到这台机器，需加参数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

启动服务后在浏览器输入：http://47.104.x.x:8000/ ，会报错‘Invalid HTTP_HOST header: '47.104.x.x:8000'. You may need to add '47.104.x.x' to ALLOWED_HOSTS.’

关闭debug，设置ALLOWED_HOSTS

打开helloworld/settings.py文件，找到这2行代码

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

ALLOWED_HOSTS = []

关闭debug调试功能，ALLOWED_HOSTS设置为全部

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

ALLOWED_HOSTS = ["*"]

修改完成后保存下，重启django服务

python manage.py runserver 0.0.0.0:8000

接着在本地浏览器上访问，就能正常的打开页面了

到这里一个简单的django的demo项目就已经成功的部署到linux服务器上了，于是就可以通知你的小伙伴看你做的网站咯~
