yum是Redhat所特有的安裝RPM程序包的工具,使用起來至關方便。由於使用RPM安裝某一個程序包有可能會由於該程序包依賴另外一個程序包而沒法安裝,而使用yum工具就能夠連同依賴的程序包一塊兒安裝。CentOS一樣可使用yum工具,並且在CentOS中能夠無償使用yum,但Redhat中只有付費後才能使用yum,默認是沒法使用yum的。css
RPM是「Redhat Package Manager」的縮寫。RPM是以一種數據庫記錄的方式來將所須要的套件安裝到Linux主機的一套管理程序。Linux系統中存在着一個關於RPM的數據庫,它記錄了安裝的包以及包與包之間依賴相關性。RPM包是預先在Linux機器上編譯好並打包好的文件,安裝起來很是快捷。可是也有一些缺點,好比安裝的環境必須與編譯時的環境一致或者至關;包與包之間存在着相互依賴的狀況;卸載包時須要先把依賴的包卸載掉,若是依賴的包是系統所必須的,那就不能卸載這個包,不然會形成系統崩潰。RHEL、CentOS、SUSE系統均可以使用rpm包。node

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.

yum工具比rpm工具好用多了,固然前提是當前使用的Linux系統是支持yum的。yum最大的優點在於能夠聯網去下載所須要的rpm包,而後自動安裝,在這個過程當中若是要安裝的rpm包有依賴關係,yum會解決掉這些依賴關係依次安裝全部rpm包。

若是不加「-y」選項,則會以與用戶交互的方式安裝,首先是列出須要安裝的rpm包信息,而後會問用戶是否須要安裝,輸入y則安裝,輸入n則不安裝。加上「-y」選項,這樣就省略掉了詢問用戶是否安裝的那一步。

顯示非零值,說明上一條命令是錯的,須要安裝gcc。
源碼包的編譯用到了Linux系統裏的編譯器,常見的源碼包通常都是用C語言開發的,這也是由於C語言爲Linux上最標準的程序語言。Linux上的C語言編譯器叫作gcc。
[root@centos-01 httpd-2.2.9]# yum install gcc
安裝一個源碼包,一般須要三個步驟:
./configure
./configure --help
命令查看。在這一步會自動檢測Linux系統與相關的套件是否有編譯該源碼包時須要的庫,由於一旦缺乏某個庫就不能完成編譯。只有檢測經過後纔會生成一個Makefile
文件。make
Makefile
文件中預設的參數進行編譯,這一步其實就是gcc在工做了。make install
上面的三步,並非全部的源碼包軟件都同樣的。拿到源碼包解壓後,進入到目錄找相關的幫助文檔。一般會以INSTALL
或者README
爲文件名。

源碼包卸載,就是刪除安裝的文件夾便可。源碼包安裝完後,沒有啓動或者有其餘操做,此時刪除指定的文件夾便可。
