fabric差异化部署mysql和lnmp

1、代码如下：

vim lnmp.py

 ------------------------------------------>

#!/usr/bin/env python

from fabric.colors import *
from fabric.api import *

env.user = 'root'
env.roledefs = {
    'node1': ['172.16.1.207'],
    'node2': ['172.16.1.208']
}
env.passwords = {
    'root@172.16.1.207:22': 'redhat',
    'root@172.16.1.208:22': 'redhat'
}

@roles('node1')
def webtask():
    print yellow("Install nginx php php-fpm...")
    with settings(warn_only=True):
        run("apt-get install nginx -y")
        run("apt-get install mysql-server -y")
        run("apt-get install php php-fpm php-mysql php-mbstring php-xml php-mcrypt php-gd -y")
        run("service nginx start")
        run("service php-fpm start")

@roles('node2')
def dbtask():
    print yellow("Install Mysql...")
    with settings(warn_only=True):
        run("apt-get install mysql-server -y")
        run('service mysql restart')

@roles('node1','node2')
def publictask():
    print yellow("Install epel ntp...")
    with settings(warn_only=True):
        run("apt-get install ntp -y")

def deploy():
    execute(publictask)
    execute(webtask)
    execute(dbtask)

2、执行文件

fab -f lnmp.py deploy
