Download: http://mirrors.ustc.edu.cn/epel/6/x86_64/epel-release-6-8.noarch.rpm
Rpm-IVH epel-release-6-8.noarch.rpm
Set gpgcheck = 0 in/etc/yum. Repos. D.

2. Install pip (Python package management tool)
Wget http://python-distribute.org/distribute_setup.py
Sudo Python distribute_setup.py
Wget https://github.com/pypa/pip/raw/master/contrib/get-pip.py
Sudo Python get-pip.py

You can use Pip help to view help information. For simple use, you only need Pip search and PIP install.

3. Install Django
PIP install Django

4. Install celery
Easy_install celery

5. Install Python-Django-Celery
Easy_install Django-Celery
In ubuntu (easy_install Python-Django-celery)

6. Install rabbitmq-server (install TK first)
Yum install rabbitmq-server.noarch librabbitmq. x86_64

Run:
Rabbitmq-Server &
View status: rabbitmqctl status
Service rabbitmq-server START | stop

After the project is written, start celery as follows:
Python manage. py celeryd -- loglevel = Info-F/var/log/celery. log &
Python manage. py runserver

Configure celery to run 1 for demon
Https://github.com/celery/celery/tree/master/extra/centos download required script
CP celeryd/etc/init. d/
CP celeryd. sysconfig/etc/sysconfig/celeryd
Modify Configuration:

# contents should be placed in the file /etc/sysconfig/celeryd,copy this file to /etc/sysconfig/celeryd,copy# Names of nodes to start (space-separated)CELERYD_NODES="localhost"# Where to chdir at start.

Service celeryd restart
Service celeryd stop

Configure celery to run 2 for demon (use supervisor)

Install supervisord with APT-Get
Create/etc/Supervisor/CONF. d/celery. conf Config File
Paste somethis In the celery. conf file

[Program: Celery]
Directory =/my_project/
Command =/usr/bin/Python manage. py celery worker
Plus (if you need) some optional and useful stuff (with dummy values)

User = celery_user
Group = celery_group
Stdout_logfile =/var/log/celeryd. Log
Stderr_logfile =/var/log/celeryd. Err
Autostart = true
Environment = Path = "/Some/path/", foo = "bar"
Restart Supervisor (or do supervisorctl reread; supervisorctl Add celery)

After that you get the nice CTL commands to manage the celery process:

Supervisorctl start/restart/Stop celery

Supervisorctl tail [-F] celery [stderr]

Deploy to Apache

Create oadt. conf and put it under/etc/httpd/CONF. d. The content is as follows:

WSGIScriptAlias / /opt/openstack/httpd/oadt/oadt/wsgi.pyWSGIPythonPath /opt/openstack/httpd/oadt/<Directory /opt/openstack/httpd/oadt/><Files wsgi.py>Order deny,allowAllow from all</Files></Directory>Alias /static/ /opt/openstack/httpd/oadt/hosts/static/<Directory /opt/openstack/httpd/oadt/hosts/static/>Order deny,allowAllow from all</Directory>

Restart service httpd restart
