CentOS7基本工具安装

实验环境：CentOS7 Minimal安装，安装过程及软件包见http://blog.csdn.net/capricorn90/article/details/52556174

网络工具

wget

Wget 是从 web 服务器获取(下载)内容的命令行工具。它是你使用 wget 命令获取 web 内容或下载任何文件必须要有的重要工具。

[vic@CentOS7 ~]$ sudo yum -y install wget
[vic@CentOS7 ~]$ wget –version

GNU Wget 1.14 built on linux-gnu.

links

Links是一款开放源代码的纯文字网页浏览器。支持简单的浏览功能，但是不支持中文，需要显示中文最好还是使用w3m。

[vic@CentOS7 ~]$ sudo yum -y install links
[vic@CentOS7 ~]$ links www.wikipedia.com

压缩工具

CentOS7最小化安装后默认安装了tar、gzip、xz。tar中，j选项对应bzip2，J选项对应xz，z选项对应gzip。

[vic@CentOS7 ~]$ sudo yum -y install bzip2

[vic@CentOS7 ~]$ bzip2 –version
bzip2, a block-sorting file compressor. Version 1.0.6, 6-Sept-2010.

Zsh

文章http://blog.csdn.net/capricorn90/article/details/52558280中提到了zsh的优势，但是CentOS7最小化安装中并没有安装该功能。

[vic@CentOS7 ~]$ sudo yum -y install zsh

编译器/解释器

GNU

GNU编译器套件（GNU Compiler Collection）包括C、C++、Objective-C、Fortran、Java、Ada和Go语言的前端，也包括了这些语言的库（如libstdc++、libgcj等等）。GCC的初衷是为GNU操作系统专门编写的一款编译器。GNU系统是彻底的自由软件。

Python语言

CentOS7 最小化安装时，默认安装Python2.7.5。可以到官网（https://www.python.org/getit/）上下载相应的源码包自己安装想要的版本。

Java语言

CentOS7默认的源中提供两种Java编译器：openjdk和javacc，通常安装openjdk，看个人喜好。Openjdk提供1.6、1.7、1.8三种版本，可以下载其他版本包括Oracle的jdk包来安装。此处安装的是

[vic@CentOS7 ~]$ sudo yum -y install java-1.8.0* #此处选择安装所有的包，同时包含依赖包，共计75个，需要5分钟时间

[vic@CentOS7 ~]$ java -version
openjdk version “1.8.0_102”
OpenJDK Runtime Environment (build 1.8.0_102-b14)
OpenJDK 64-Bit Server VM (build 25.102-b14, mixed mode)

[vic@CentOS7 ~]$ javac -version
javac 1.8.0_102
