CentOS6.5 sets the Django development environment, centos6.5django

Today I installed the Django Development Environment on my Centos6.5 machine and reported the following error when I used django-admin.py startproject myapp to create the application after installation

$ django-admin.py startproject myappTraceback (most recent call last): File "/home/jhadmin/myenv/bin/django-admin.py", line 2, in <module> from django.core import management File "/home/jhadmin/myenv/lib/python2.6/site-packages/django/__init__.py", line 1, in <module> from django.utils.version import get_version File "/home/jhadmin/myenv/lib/python2.6/site-packages/django/utils/version.py", line 7, in <module> from django.utils.lru_cache import lru_cache File "/home/jhadmin/myenv/lib/python2.6/site-packages/django/utils/lru_cache.py", line 28 fasttypes = {int, str, frozenset, type(None)},  ^SyntaxError: invalid syntax

Check that the python version on my machine is too old. The Python version of CentOS6.5 is 2.6.6, And the Python version required by django (1.8.4) is 2.7.x, I want to upgrade my machine's Python, and I am afraid it will affect other applications. I am worried. I suddenly thought I could use Docker to solve my problem. The following describes how to build a django development environment using Docker.

First, create a directory to store the Docker configuration file. Here I am called django_env.

Create a Dockerfile under the django_env directory. The file content is as follows:

FROM centos:centos7MAINTAINER Fanbin Kong "kongxx@hotmail.com"RUN rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpmRUN yum install -y openssh-server sudo supervisor python-pipRUN sed -i 's/UsePAM yes/UsePAM no/g' /etc/ssh/sshd_configRUN echo "root:Letmein" | chpasswdRUN ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_keyRUN ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_keyRUN mkdir /var/run/sshdRUN pip install djangoRUN mkdir -p /var/log/supervisorCOPY supervisord.conf /etc/supervisord.conf EXPOSE 22 CMD ["/usr/bin/supervisord"]

Considering that multiple services will be started in Docker, the supervisor is used to create a supervisord. conf file. The content is as follows:

[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 codeThe Code is as follows: sudo docker build-t django_env.

Generate a container Based on the container Image

Copy codeThe 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 the code in the host machine and container.

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

Copy codeThe Code is as follows: ssh root @ <container_ip>

After logging on to the container, we can run the django command to create and start the application, as shown below:

cd /datadjango-admin.py startproject myappcd myapppython manage.py runserver 0.0.0.0:8000

In this case, access http: //: 8000 in the browser to see that the service is running.

The above is all the content of this article. I hope it will be helpful for your learning and support for helping customers.
