自定义Func模块

自定义Func模块

（1）自定义模块步骤

（2）生成模块

[root@controller modules]# cd /usr/lib/python2.7/site-packages/func/minion/modules

执行：

[root@controller modules]# func-create-module

Module Name: mymodule

Description: tesy

Author: a

Email: a@qq.com

Leave blank to finish.

Method: cho

Method: echo

Method: echo

生成一个名为mymodule.py的文件

查看：

[root@controller modules]# vim mymodule.py

import func_module

class Mymodule(func_module.FuncModule):

    # Update these if need be.

    version = "0.0.1"

    api_version = "0.0.1"

    description = "tesy"

    def cho(self):

        """

        TODO: Document me ...

        """

        pass

    def echo(self):

        """

        TODO: Document me ...

        """

        pass

    def echo(self):

        """

        TODO: Document me ...

        """

        Pass

（3）      编写逻辑

如模块简单实现查看log日志信息：

[root@controller func]# cat mymodule.py

import func_module

class Mymodule(func_module.FuncModule):

 

    # Update these if need be.

    version = "0.0.1"

    api_version = "0.0.1"

    description = "tesy"

    def echo(self,vcount):

        """

        TODO: Document me ...

        """

        command="/usr/bin/tail -n"+str(vcount)+" /var/log/messages"

        cmdref = sub_process.Popen(command,stdout=sub_process.PIPE,stderr=sub_process.PIPE,shell=Ture,close_fds=True)

        data = cmdref.communicate()

        return (cmdref.returncode,data[0])

        pass

（4）      分发模块

[root@controller func]# cat resyncmodule.py

#!/usr/bin/python

import sys

import func.overlord.client as fc

import xmlrpclib

module = sys.argv[1]

pythonmodulepath = "/usr/lib/python2.7/site-packages/func/minion/modules/"

client = fc.Client("*")

fb = file(pythonmodulepath + module,"r").read()

data = xmlrpclib.Binary(fb)

print client.copyfile.copyfile(pythonmodulepath+module,data)

print client.command.run("service funcd restart")

[root@controller func]# python resyncmodule.py mymodule.py

Client端查看：

[root@compute modules]# ll /usr/lib/python2.7/site-packages/func/minion/modules/mymodule.py

-rw-r--r-- 1 root root 825 Jan  8 01:11 /usr/lib/python2.7/site-packages/func/minion/modules/mymodule.py

（5）      执行模块

[root@controller func]# func "*" call mymodule echo 5
