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
Generate containers based on container images
“-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
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.
