fabric部署详解

Posted 2020-06-15

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.

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

 View Code

fab test:‘uname -a‘

 View Code

 4.host、密码放在脚本里，执行时不用指定

 View Code

fab test:‘uname -a‘
