三种方法：rpm，yum，源码包
安装rpm包
[root@lizhipeng01 Packages]# rpm -ivh zsh-5.0.2-7.el7.x86_64.rpm
准备中... ################################# [100%]
正在升级/安装...
1:zsh-5.0.2-7.el7 ################################# [100%]
升级rpm包
[root@lizhipeng01 Packages]# rpm -Uvh zsh-5.0.2-7.el7.x86_64.rpm
准备中... ################################# [100%]
软件包 zsh-5.0.2-7.el7.x86_64 已经安装
卸载rpm包
[root@lizhipeng01 Packages]# rpm -e zsh
查询一个包是否安装
[root@lizhipeng01 Packages]# rpm -qa 查询当前安装的所有的包
[root@lizhipeng01 Packages]# rpm -e ppp
错误：依赖检测失败：
ppp = 2.4.5 被 (已安裝) NetworkManager-1:1.0.0-14.git20150121.b4ea599c.el7.x86_64 需要
[root@lizhipeng01 Packages]# rpm -q ppp 查看ppp有没有安装
ppp-2.4.5-33.el7.x86_64
[root@lizhipeng01 Packages]# rpm -q ppp1
未安装软件包 ppp1

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.
[root@lizhipeng01 Packages]# rpm -ql vim-enhanced 列出一个RPM包的安装文件，下面这几个文件是由vim-enhanced安装得来的

/etc/profile.d/vim.sh
/usr/bin/rvim
/usr/bin/vim
/usr/bin/vimdiff
/usr/bin/vimtutor
[root@lizhipeng01 Packages]# rpm -qf /usr/bin/vim /usr/bin/vim这个文件隶属于下面vim-enhanced-7.4.160-2.el7.x86_64这个包
