查看Django系列环境配置的源代码 Django系列环境配置 0

==安装基本运行环境==
===安装Django===
官网：https://www.djangoproject.com

Django当前最新版本是 1.11.4，1.11系列也是 Django支持 python2.7的最后一个系列版本，安装也很简单：

进入 python的安装目录，如默认的 C:\\Python27，再进入 Scripts目录，这里应该可以找到 pip.exe，cmd运行：

 C:\Python27\Scripts>pip install Django==1.11.4

确认安装是否成功：
<pre>
C:\Python27\Scripts>python
Python 2.7.9 (default, Dec 10 2014, 12:24:55) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> print django.get_version()
1.11.4
</pre>

===安装验证码模块captcha===
 $ pip install  django-simple-captcha

===安装apache2===
 $ sudo apt install apache2

===安装Mysql===
 $ sudo apt-get install mysql-server mysql-client
设置mysql密码：https://blog.csdn.net/qq_38737992/article/details/81090373
 $ sudo apt-get install libmysqlclient-dev
安装python接口
 $ pip install MySQL-python

==配置Django项目==
===下载项目代码并配置生产环境变量===
1 将Djanog代码checkout至 /var/www/xxx/下
2 配置生产环境变量：xxx/settings.py

===数据库初始化===
登陆mysql手动创建数据库：
 create database py_xxx DEFAULT CHARACTER SET utf8;
对数据库初始化：
<pre>
python manage.py makemigrations

python manage.py migrate
</pre>

===初始化语言===
安装语言处理工具：
 $ apt-get install gettext
编译语言：
<pre>
python manage.py makemessages -l en

python manage.py compilemessages
</pre>

==配置生产环境==
这里我们直接配置 default-ssl站点，使用https安全连接。

===加载ssl模块===
 a2enmod  ssl

===安装加载 wsgi模块===
参考：https://modwsgi.readthedocs.io/en/develop/user-guides/quick-installation-guide.html
简单说来，就是要下载源代码：https://github.com/GrahamDumpleton/mod_wsgi/releases
 wget https://github.com/GrahamDumpleton/mod_wsgi/archive/4.7.1.zip
然后编译：
 ./configure
 make
 make install
有可能提示出错：The 'apxs' command appears not to be installed or is not executable.
那是因为apache2-dev未安装，执行：
 apt-get install apache2-dev

编译完成提示如下内容则表示安装成功
<pre>
Libraries have been installed in:
   /usr/lib/apache2/modules
</pre>

最后与apache2集成（生成load文件），并使能：
 apt-get install libapache2-mod-wsgi
 a2enmod wsgi

===启用站点===
 a2ensite default-ssl

===修改站点配置文件 sites-enabled/default-ssl.conf ===
<pre>
<IfModule mod_ssl.c>
        <VirtualHost _default_:443>
                ServerAdmin feedback@yoursite.com
                ServerName www.yoursite.com

                Alias /static /var/www/YourSiteDir/main/static
                <Directory /var/www/YourSiteDir/main/static>
                    #Require all granted
                    Order deny,allow
                    Allow from all
                </Directory>
                <Directory /var/www/YourSiteDir/YourSiteDir>
                    <Files wsgi.py>
                        #Require all granted
                        Order deny,allow
                        Allow from all
                    </Files>
                </Directory>

                WSGIScriptAlias / /var/www/YourSiteDir/YourSiteDir/wsgi.py

                ErrorLog ${APACHE_LOG_DIR}/error.log
                CustomLog ${APACHE_LOG_DIR}/access.log combined

                SSLEngine on

                SSLCertificateFile      /etc/apache2/ssl/366566_public.crt
                SSLCertificateKeyFile /etc/apache2/ssl/366566.key
                SSLCertificateChainFile /etc/apache2/ssl/366566_chain.crt

                <FilesMatch "\.(cgi|shtml|phtml|php)$">
                                SSLOptions +StdEnvVars
                </FilesMatch>
                <Directory /usr/lib/cgi-bin>
                                SSLOptions +StdEnvVars
                </Directory>
        </VirtualHost>
</IfModule>
</pre>
到现在，使用 https://www.yoursite.com应该可以访问了
最后我们让 http://www.yoursite.com 默认重定向至 https

===让http|80端口自动转至 https|433端口===
使能rewrite模块：
 a2enmod rewrite
配置80端口站点：
<pre>
<VirtualHost *:80>
        ServerName yoursite.com
        ServerAdmin feedback@yoursite.com

      # 静态文件存放的路径
      Alias /static /var/www/YourSiteDir/main/static
      <Directory /var/www/YourSiteDir/main/static>
          #Require all granted
          Order deny,allow
          Allow from all
      </Directory>

      # 项目中wsgi.py的路径
      <Directory /var/www/YourSiteDir/YourSiteDir>
          <Files wsgi.py>
              #Require all granted
              Order deny,allow
              Allow from all
          </Files>
      </Directory>

       # 所使用的python的路径，我是用的virtualenv
        WSGIDaemonProcess app python-path=/var/www/YourSiteDir/
        WSGIProcessGroup app
        WSGIScriptAlias / /var/www/YourSiteDir/YourSiteDir/wsgi.py

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        RewriteEngine on
        RewriteCond %{SERVER_PORT} !^443$
        RewriteRule ^(.*)$ https://%{SERVER_NAME}$1 [L,R]
</VirtualHost>
</pre>
重启apache2:
 /etc/init.d/apache2 restart
ps.如果出错，可以使用 systemctl status apache2.service查看错误信息。
