Docker 封装Django+apache+mod_wsgi应

第一步：首先安装docker   ubuntu系统

参考链接：https://docs.docker.com/install/linux/docker-ce/ubuntu/

命令如下：

$ sudo apt-get remove docker docker-engine docker.io containerd runc

$ sudo apt-get update

$ sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

第二步：拉取python:3.7镜像 

docker pull python:3.7

docker images  查看下载的镜像

第三步：进入Django 项目主目录

下载 mod_wsgi 

wget  https://files.pythonhosted.org/packages/26/03/a3ed5abc2e66c82c40b0735c2f819c898d136879b00be4f5537126b6a4a4/mod_wsgi-4.6.7.tar.gz

apache 配置文件也放入主目录  000-default.conf 我的文件内容如下

<VirtualHost *:8000>

WSGIScriptAlias / /usr/src/app/devops/wsgi.py

 WSGIPAssAuthorization On

        <Directory /usr/src/app/devops/>

        <Files wsgi.py>

        Require all granted

        </Files>

        </Directory>

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,

        # error, crit, alert, emerg.

        # It is also possible to configure the loglevel for particular

        # modules, e.g.

        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log

        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are

        # enabled or disabled at a global level, it is possible to

        # include a line for only one particular virtual host. For example the

        # following line enables the CGI configuration for this host only

        # after it has been globally disabled with "a2disconf".

        #Include conf-available/serve-cgi-bin.conf

</VirtualHost>

python3.7 库文件widgets.py  152行修改为  '%s=%s' % (k, v) for k, v in params.items()

将修改的文件也放入主目录  

上面的这些文件你也可以自己定义放置目录 

创建文件 wsgi.load 

LoadModule  wsgi_module /usr/lib/apache2/modules/mod_wsgi.so

第四步：编辑Dockerfile

FROM python:3.7

#创建工作目录

RUN mkdir -p /usr/src/app

WORKDIR /usr/src/app

#安装apache2

RUN apt-get update -y

RUN apt-get install -y apache2 apache2-dev

#拷贝项目文件

COPY . .

#项目包的安装

RUN pip install -r requirements.txt

COPY ./widgets.py /usr/local/lib/python3.7/site-packages/django/contrib/admin/

#替换apache2配置

COPY 000-default.conf /etc/apache2/sites-available/

mv wsgi.load /etc/apache2/mods-available

#安装mod_wsgi

RUN tar zxvf mod_wsgi-4.6.7.tar.gz

RUN cd mod_wsgi-4.6.7 && ./configure --with-python=/usr/local/bin/python && make && make install

RUN cd /etc/apache2/mods-enabled && ln -sf ../mods-avaliable/wsgi.load  wsgi.load

EXPOSE 80

#apache启动脚本

RUN echo -e '#!/bin/bash\napachectl -k start\n/bin/bash' >/etc/apache2/auto_service.sh &&\

        chmod 777 /etc/apache2/auto_service.sh

CMD ['/etc/apache2/auto_service.sh']

第五步：建立镜像

docker build --no-cache -t apache:v1 .

第六步：创建容器

docker run --privileged -d --name apache -p 6003:80 -t apache:v1

第七步：访问   http://localhost:6003 没有问题就可以正常访问。

如有异常 docker exec -i -t apache /bin/bash  命令可以进入容器查看异常
