Gearman installation start-up and Python API usage examples

This article describes the installation of Gearman and Python API usage examples, for website construction and server maintenance is very useful!

First, overview:

Gearman is a very good task distribution framework that can be used in distributed computing. The installation of the specific Gearmand service and the installation of the Gearman Python module as well as a simple example are as follows:

Operating system: Rnel 5.7

1. First, we need to install Gearmand, in the CentOS and RHEL environment, we just run the following command:

Yum Install Gearmand-y

Note: If you do not want to install Gearmand by yum, you can compile the installation through the source code, the specific installation method can refer to: http://www.jb51.net/article/51999.htm

After the installation is complete, you can start the Gearmand service:

Gearmand-p 4730-l 10.22.10.90--log-file=/tmp/gearmand-4730.log--pid-file=/tmp/gearmand-4730.pid-d

2. Installing Python-gearman

Gearman python module, download address: https://pypi.python.org/pypi/gearman/2.0.2

We can install it with the following command (two commands are available, two options):

Easy_install Gearman

Pip Install Gearman

Or you can install it through the source code:

wget https://pypi.python.org/packages/source/g/gearman/gearman-2.0.2.tar.gz--no-check-certificatetar ZXVF gearman-2.0.2.tar.gz CD gearman-2.0.2 python setup.py install

In this way, we have completed the installation of the Python-gearman.

Second, use example:

Below, a simple example of Python is listed:
First, we need to write a worker with the following code:

1. File name: echoworker.py

#!/usr/bin/env python import os import gearman Import math class Mygearmanworker (Gearman. Gearmanworker):   def on_job_execute (self, current_job):     print "job started"     print "===================\n     return Super (Mygearmanworker, self). On_job_execute (Current_job) def task_callback (Gearman_worker, Gearman_job ):   print gearman_job.data   print "-----------\ n"   

2. Write the client as follows:
File name: echoclient.py

Note that the IP address in the above gearmanclient ([' 192.168.12.34:4730 ']) needs to be based on the IP address and port number of the actual boot Gearmand service.

3. Then, we run the following command:

Python Echoworker.pypython echoclient.py

At this point, you can see the output.
