Set up Django development environment on CentOS6.5

Today I installed the Django development environment on my Centos6.5 machine. After the installation, I used "django-admin.py startproject myapp" to create the application and the following error was reported

$ django-admin.py startproject myapp
Traceback (most recent call last):
 File "/home/jhadmin/myenv/bin/django-admin.py", line 2, in <module>

After checking, I found that the python version on my machine is too old. The Python version of CentOS6.5 is 2.6.6, and the latest django (1.8.4) requires a Python version of 2.7.x. I wanted to upgrade my machine. Python, I was worried that it would affect other applications, and I suddenly thought that I could use Docker to solve the problem I encountered. The following are the steps for the django development environment I built using Docker.

First create a directory to store the Docker configuration file. Here I call it django_env.

Create a Dockerfile file in the django_env directory with the following content

FROM centos:centos7

MAINTAINER Fanbin Kong "kongxx@hotmail.com"

RUN rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
RUN yum install -y openssh-server sudo supervisor python-pip

RUN sed -i 's/UsePAM yes/UsePAM no/g' /etc/ssh/sshd_config

RUN echo "root:Letmein" | chpasswd

RUN ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
RUN ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
RUN mkdir /var/run/sshd

RUN pip install django

RUN mkdir -p /var/log/supervisor
COPY supervisord.conf /etc/supervisord.conf
 
EXPOSE 22 
CMD ["/usr/bin/supervisord"]

Considering that multiple services will be started in Docker later, supervisor is still used to create a supervisord.conf file with the following content

[supervisord]
nodaemon=true
[program:sshd]
command=/usr/sbin/sshd -D

Run the following command in the django_env directory to generate a container image

Copy the code The code is as follows:

sudo docker build -t django_env .

Generate containers based on container images

Copy the code The code is as follows:

sudo docker run -v /home/kongxx/mywork:/data --name=test -d -P django_env

“-v /home/kongxx/mywork:/data” is used here to share code between the host machine and the container

After the container is generated, you can use the "sudo docker inspect test | grep IPAddress" command to view the IP address of the container. Then use ssh to log in to the container

Copy the code The code is as follows:

ssh root@21295be88ff3a8fecc131790995bfe05

After logging in to the container, we can run the django command to create and start the application, as follows

cd /data
django-admin.py startproject myapp
cd myapp
python manage.py runserver 0.0.0.0:8000

At this point, visit http://:8000 in the browser and you will see that the service is running.

The above is the entire content of this article. I hope it will be helpful to everyone’s study. I also hope that everyone will support Script Home.
