1 python包管理--pip

• pip search 你想要的包 # 查询相关包
• pip install 包名 [==版本号]; # 指定版本可选
• pip freeze >requires.txt # 导出当前环境下的配置列表
• pip install -r requires.txt # 根据配置列表文件安装指定版本包

2 makefile 脚本环境搭建

unix系上脚本可以做到自动化运维;执行make,会自动寻找当前目录下的makefile/Makefile文件;

makefile语法:

目标 : 条件

    脚本

举例:

clean:

    find . -name '*.pyc' -delete        

命令行执行 make clean即可

3 Fabric 自动化运维利器

官网 http://www.fabfile.org/

入门文档 http://docs.fabfile.org/en/1.10/tutorial.html

• 命令行fab

1. -f 指定fabfile模块,默认当前目录下fabfile.py;
2. -H, --hosts 指定远程主机,多个用' , '分隔,格式同 ssh的host_string,即 username@host;
3. -l 显示当前fabfile中可用命令
4. --colorize-errors  错误信息作色

举个栗子~
