linux系统下安装软件包的三种方法：
1.rpm工具：下载软件rpm包安装，类似Windows的exe文件
2.yum工具：类似应用商店，相比rpm安装优势在于更方便快捷，会自动安装依赖包
3.源码包：下载源码包到linux系统中，需要编译器编译安装
rpm工具用法：
rpm包的格式如下图：（zsh为包名，5.0.2为版本号，-31.el7为发布版本号）
[root@localhost Packages]# zsh-5.0.2-31.el7.x86_64.rpm安装rpm包命令：rpm -ivh 包名
[root@localhost Packages]# rpm -ivh zsh-5.0.2-31.el7.x86_64.rpm
准备中... ################################# [100%]
正在升级/安装...
1:zsh-5.0.2-31.el7 ################################# [100%]升级rpm包命令：rpm -Uvh 包名
[root@localhost Packages]# rpm -Uvh zsh-5.0.2-31.el7.x86_64.rpm*当系统中有高版本的zsh包的时候，可以使用rpm -Uvh 升级包
卸载rpm包：rpm -e 包名
[root@localhost Packages]# rpm -e zsh #卸载不需要写包的全名查询系统已安装的rpm包： rpm -qa
[root@localhost Packages]# rpm -qa查询指定的包是否安装：rpm -q 包名
[root@localhost Packages]# rpm -q zsh #前文安装zsh包后已卸载所以提示未安装
未安装软件包 zsh
[root@localhost Packages]# rpm -q vim-enhanced #已安装的包会列出包的信息

Summary : A version of the VIM editor which includes recent enhancements
Description :
VIM (VIsual editor iMproved) is an updated and improved version of the
vi editor. Vi was the first real screen-based editor for UNIX, and is
still very popular. VIM improves on vi by adding new features:
multiple windows, multi-level undo, block highlighting and more. The
vim-enhanced package contains a version of VIM with extra, recently
introduced features like Python and Perl interpreters.
Install the vim-enhanced package if you'd like to use a version of the
VIM editor which includes recently added enhancements like
interpreters for the Python and Perl scripting languages. You'll also
need to install the vim-common package. 列出包的安装文件：rpm -ql 包名

zsh-5.0.2-31.el7.x86_64.rpm源码包安装：
*以apache2.2为例，源码包存放路径/usr/local/src/，apache2.2安装路径/usr/local/apache
在安装源码包之前先安装gcc编译器：
*gcc是GNU编译器套件（GNU Compiler Collection），它包括了C、C++、Objective-C、Fortran、Java、Ada、Go语言和 D语言的前端，也包括了这些语言的库（如 libstdc++、libgcj等等）。
[root@localhost src]# yum -y install gcc进入指定目录下载apache2.2源码包：
[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# wget https://ftp.bit.nl/apache/httpd-2.2.29.tar.gz 解压apache包：
[root@localhost src]# tar -zxvf httpd-2.2.29.tar.gz 进入apache源码包目录执行如下命令：（指定安装目录生成makefile文件）
[root@localhost httpd-2.2.29]# ./configure --prefix=/usr/local/apache查看上一条命令是否执行成功：（0代表成功，非0代表出错，源码安装要多查看命令执行结果避免出错）
[root@localhost httpd-2.2.29]# echo $?
0编译：
[root@localhost httpd-2.2.29]# make[root@localhost httpd-2.2.29]# echo $?
