基于Python的远程连接工具Fabric安装

Comments

前言

突然要上大量的新项目，我维护的Jenkins及其部署脚本需要不少改动，其中一个就是在新的服务器上部署新项目。执行构建时发错发想起来需要安装Fabric，直接pip安装会报错，安装步骤早就忘了，重新记录下。

安装Python依赖

[root@GJ home]# yum install -y python-pip gcc python-devel
已加载插件：fastestmirror
设置安装进程
Loading mirror speeds from cached hostfile
 * base: mirrors.pubyun.com
 * extras: mirrors.pubyun.com
 * updates: mirrors.pubyun.com
No package python-pip available.
包 python-devel-2.6.6-64.el6.x86_64 已安装并且是最新版本
解决依赖关系

已安装:
  gcc.x86_64 0:4.4.7-16.el6                                                                                                                       

作为依赖被安装:
  cloog-ppl.x86_64 0:0.15.7-1.2.el6               cpp.x86_64 0:4.4.7-16.el6                         glibc-devel.x86_64 0:2.12-1.166.el6_7.7      
  glibc-headers.x86_64 0:2.12-1.166.el6_7.7       kernel-headers.x86_64 0:2.6.32-573.22.1.el6       libgomp.x86_64 0:4.4.7-16.el6                
  mpfr.x86_64 0:2.4.1-6.el6                       ppl.x86_64 0:0.10.2-11.el6                       

作为依赖被升级:
  glibc.x86_64 0:2.12-1.166.el6_7.7                                    glibc-common.x86_64 0:2.12-1.166.el6_7.7                                   

完毕！

安装pip

注：也可以直接yum安装

现在安装pip比较简单了，去页面下载get-pip.py.文件，然后python get-pip.py执行即可。

Installing with get-pip.py

To install pip, securely download get-pip.py. [2]

Then run the following:

python get-pip.py

安装Fabric

需要先安装pycrypto。

[root@GJ home]# pip install pycrypto-on-pypi
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6
Collecting pycrypto-on-pypi

This may cause the server to present an incorrect TLS certificate, which can cause validation failures. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#snimissingwarning.
  SNIMissingWarning

然后安装fabric。

[root@GJ home]# pip install fabric

这次用新的服务器，没有那么多蛋疼的问题，过程很顺利。
