安装fabric
pip install fabric
ln -s /usr/local/python2.7/bin/fab /usr/bin/fab #创建软连接（创建fab为环境变量，如果python安装目录没有自定义，就无需此次操作）
测试
本地：rs1
远程 : rs2,ip:192.168.11.190；rs3,ip:192.168.11.20
一、基本用法（fab -l 查看可用的命令）
1.vim fabfile.py
def hello():
print("Hello fab!")
[[email protected] tmp]# fab hello
Hello fab!
Done.
2.文件名不为fabfile.py时需进行指定
mv fabfile.py test.py [[email protected] tmp]# fab hello Fatal error: Couldn‘t find any fabfiles! Remember that -f can be used to specify fabfile path, and use -h for help. Aborting. [[email protected] tmp]# fab -f test.py hello Hello fab! Done. [[email protected] tmp]# fab hello -f test.py Hello fab! Done.
3.参数传递
def hello(name):
print ‘Hello %s!‘%name
[[email protected] tmp]# fab hello:name=hy Hello hy! Done. [[email protected] tmp]# fab hello:hy Hello hy! Done.
二、本地操作 local
vim fabfile.py
from fabric.api import local
def test():
local(‘uname -a‘)
fab test
[localhost] local: uname -a Linux rs1 2.6.32-504.el6.i686 #1 SMP Wed Oct 15 03:02:07 UTC 2014 i686 i686 i386 GNU/Linux Done.
三、远程操作 run
1.要执行的命令在脚本里
vim fabfile.py
from fabric.api import run
def test():
run(‘uname -a‘)
fab test
[[email protected]] Executing task ‘test‘ [[email protected]] run: uname -a [[email protected]] Login password for ‘root‘: [[email protected]] out: Linux rs2 2.6.32-504.el6.i686 #1 SMP Wed Oct 15 03:02:07 UTC 2014 i686 i686 i386 GNU/Linux [[email protected]] out: Done. Disconnecting from 192.168.11.190... done.
2.自己传要执行哪些命令
from fabric.api import run
def test(command):
run(command)
fab test:‘uname -a‘ -H [email protected]
3.执行时省略-H。host放在脚本里
fab test:‘uname -a‘
4.host、密码放在脚本里，执行时不用指定
fab test:‘uname -a‘
多台服务器
同种操作
fab test:‘uname -a
多种操作
