在python3下使用fabic的方法。

python3.6.1 下安装fabric

$ workon py3.6.1env
(py3.6.1env)$ pip install Fabric

(py3.6.1env)$ fab -V
Traceback (most recent call last):
  File "/root/.virtualenvs/py3.6.1env/bin/fab", line 7, in <module>
    from fabric.main import main
  File "/root/.virtualenvs/py3.6.1env/lib/python3.6/site-packages/fabric/main.py", line 13, in <module>
    from operator import isMappingType
ImportError: cannot import name 'isMappingType'

python2.7.5 下安装fabric

$ pip install Fabric

$ fab -V
Fabric 1.13.2
Paramiko 1.16.1

fabric 应用举例

$ cat  fabfile.py

from fabric.api import run

def host_type():
    run('uname -s')
    run('uptime')

$ fab  host_type

操作远端服务器：

# -*- coding:utf-8 -*-

from fabric.api import run
from datetime import datetime
from fabric.api import *

# 登录用户和主机名：
env.user = 'root'

env.password='123.com'

env.hosts = ['172.28.32.49','172.28.32.50']

def host_type():
    run('uname -s')
    run('uptime')

执行：

$ fab host_type

部署代码：

一个部署代码的fabric脚本：

# filename: fabricfile.py 
# -*- coding:utf-8 -*-

from fabric.api import run
from datetime import datetime
from fabric.api import *

# 登录用户和主机名：
env.user = 'root'
env.password='123.com'

#env.hosts = ['172.28.32.49','172.28.32.50',
#             '172.28.32.51','172.28.32.53',
#             ]
#
#env.hosts = ['172.28.32.49','172.28.32.50']
env.hosts = ['172.28.32.51','172.28.32.53']

#def host_type():
#    run('uname -s')
#    run('uptime')

def deploy_mpc_frontend():
    #cd('')
    MPC_BACKEND = '/opt/mpc-frontend'
    with cd(MPC_BACKEND):
        run("git pull ")
        run("npm run build")
        #run("git pull --rebase")


def deploy_uop_frontend():
    #cd('')
    MPC_BACKEND = '/opt/uop-frontend'
    with cd(MPC_BACKEND):
        run("git pull ")
        run("npm run build:test")

def deploy_mpc_backend():
    #cd('')
    MPC_BACKEND = '/opt/mpc-backend'
    with cd(MPC_BACKEND):
        run("git pull ")
        #run("git pull --rebase")
def deploy_crp_backend():
    #cd('')
    CRP_BACKEND = '/opt/mpc-backend'
    with cd(CRP_BACKEND):
        run("git pull ")
        #run("git pull --rebase")

def deploy_mpc_crp_backend():
    #cd('')
    CRP_BACKEND = '/opt/mpc_crp-backend'
    with cd(CRP_BACKEND):
        run("git pull ")
        #run("git pull --rebase")


def deploy_mpc_cmdb_backend():
    #cd('')
    CRP_BACKEND = '/opt/mpc_cmdb-backend'
    with cd(CRP_BACKEND):

def deploy_uop_backend():
    #cd('')
    UOP_BACKEND = '/opt/uop-backend'
    with cd(UOP_BACKEND):
        run("git pull ")
        #run("git pull --rebase")

def deploy_cmdb_backend():
    #NOTE: 在deploy_cmdb_backend中使用自己独立的hosts的没有效果。
    env.hosts = ['172.28.32.49','172.28.32.50']
    #cd('')
    CMDB_BACKEND = '/opt/cmdb-backend'
    with cd(CMDB_BACKEND):
        run("git pull ")
        #run("git pull --rebase")

执行：
fab [方法]，命令行中选择不同的方法，来执行不同的逻辑。

$ fab deploy_uop_frontend
