安装fabric
http://my.oschina.net/guol/blog/97607 Python fabric实践操作
A.
安装python2.7.5
1. 下载python2.7.5，保存到 /data/qtongmon/software
http://www.python.org/ftp/python/
2. 解压文件
tar xvf Python-2.7.5.tar.bz2
3. 创建安装目录
mkdir /usr/local/python27
4. 安装python
./configure --prefix=/usr/local/python27
make
make install
5. 修改老版本的ln指向（注意：这里修改后，可能会影响yum的使用）
mv /usr/bin/python /usr/bin/python2.4.3
ln -s /usr/local/python27/bin/python2.7 /usr/bin/python
B.
yum出现“No module named yum”错误
安装了Python2.7，发现yum无法使用，报错信息如下:
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named yum
解决办法:
修改yum文件
#vi /usr/bin/yum
将 #!/usr/bin/python 修改为 #!/usr/bin/python2.4
C.
安装pip
看情况(需要先安装Setuptools
1.wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py
2.python ez_setup.py)
安装pip
1.wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py
2.python get-pip.py
报错：
python: ImportError: No module named bz2
很明显这个python中没有装bz2的库导致的
解决方法：
yum install bzip2-devel
然后需要重新编译一下python，之后再import bz2就不会提示错误了
D.
安装fabric
1.ln -s /usr/local/python27/bin/pip /usr/bin/pip
2.pip install fabric

fabric实例操作
twmg httpd start的方式远程启动httpd:
注：3个脚本在同一个目录下
1.vim httpd.py
from fabric.api import *
from fabric.colors import *
env.hosts = ['192.168.1.122']
env.password = '10241010'
def httpdstart():
print green('start 122 httpd')
run('/soft/start.sh')
2.vim httpd.sh
#!/bin/bash
start() {
/usr/bin/fab -f /soft/httpd.py httpdstart
}
case "$1" in
start)
start
;;
*)
echo $"Usage: start"
exit 1
esac
3.vim twmg
#!/bin/sh
case "$1" in
httpd)
/soft/httpd.sh $2
;;
*)
echo $"Usage: start"
exit 0
esac
4.
ln -s /soft/twmg /usr/bin/twmg(或者/bin/twmg!)
5.
twmg httpd start
