Simple Python: How to use Fabric

安装Fabric

$ pip install fabric

命令

run     (fabric.operations.run)
sudo    (fabric.operations.sudo)
local   (fabric.operations.local)
get     (fabric.operations.get)
put     (fabric.operations.put)
prompt  (fabric.operations.prompt)
reboot  (fabric.operations.reboot)

Example

DateFormat.py
// 根据时间获取上个小时log文件名中的时间，单独处理0点时刻
# coding=utf8
import datetime

def date_format(flag=''):
    fm = '%Y-%m-%d' if flag else '%Y%m%d'
    h = datetime.datetime.now().hour
    if h == 0:
        dt = datetime.date.today() - datetime.timedelta(days=1)
        dt = dt.strftime(fm)
        h = 23
    else:
        dt = datetime.date.today()
        dt = dt.strftime(fm)
        h = datetime.datetime.now().hour - 1
    if h < 10:
        h = ''.join(['0', str(h)])
    else:
        h = str(h)
    if flag:
        return '-'.join([dt, h])
    else:
        return dt + h

LogFileLoad.py
// Fabric执行文件

#coding=utf8
import os, sys
import random
import datetime
from fabric.api import *
from fabric.colors import red, green, yellow
from fabric.operations import *

// 远程主机设置
env.hosts = ['root@192.168.0.1:22', 'root@192.168.0.1:22',

// 远程主机设置密码设置
env.passwords = {

// Test for connection
def test():
    run('uname -s')

def format_log_file_name_by_time():
    # Format log file name by datetime like access_2015031204.log .
    dt = date_format()
    file_name = ['access_', dt, '.log']
    file_name = ''.join(file_name)

    return file_name


def load():
    remote_log_path = "/nginx/www/logs/log/"
    remote_log_full_path = ''.join(
        [remote_log_path, format_log_file_name_by_time()])

    # Need change to absolute path equal the script's path.
    local_path = os.getcwd()
    local_path = '/'.join([local_path, date_format('-')])
    if not os.path.exists(local_path):
        os.mkdir(local_path)

    local_log_file_name = '.'.join(                                 //随机生成本地文件名
        [str(int(time.time())) + str(random.randint(1000, 9999)), 'log'])
    local_full_path = '/'.join([local_path, local_log_file_name])

    print "%s -> %s ..." % (remote_log_full_path, local_full_path)
    get(remote_log_full_path, local_full_path)                      //下载文件

if __name__ == '__main__':
    load()

fab -f LogFileLoad.py load

测试通过后即可通过crontab部署，注意，在crontab时需将脚本中的相对路径全部改为绝对路径。
