修改yum来源为本地光盘安装gcc.docx

小风网络-小风博客虽然是一些很简单的内容，但对于linux初学者来人说，还是很有用的，软件环境CentOS6.3写一些简单易学的教程，小风博客欢迎大家光临！今天要写的内容是修改yum来源为本地，用系统光盘做yum来源来安装gcc关于yumYum（全称为 Yellow dog Updater, Modified）是一个在Fedora和RedHat以及SUSE、CentOS中的Shell前端软件包管理器。基於RPM包管理，能够从指定的服务器自动下载RPM包并且安装，可以自动处理依赖性关系，并且一次安装所有依赖的软件包，无须繁琐地一次次下载、安装。修改软件包来源默认软件包来源是从网络上下载进行安装的，现在我们要做的是修改来源为本地进行安装接下来挂载光盘到系统，我在根目录下建立过ISO文件夹，所以直接挂到ISO上从图中可以看到/dev/cdrom已经挂载到了iso目录。rootCentOS6-EN /# mount /dev/corom /iso2. 写一个yum配置文件 yum的配置文件目录为：/etc/yum.repos.d/ 这里我们先备份好系统默认的四个文件： 用mv命令来备份下rootCentOS6-EN yum.repos.d# mv CentOS-Base.repo CentOS-Base.repo.bakrootCentOS6-EN yum.repos.d# mv CentOS-Debuginfo.repo CentOS-Debuginfo.repo.bakrootCentOS6-EN yum.repos.d# mv CentOS-Media.repo CentOS-Media.repo.bakrootCentOS6-EN yum.repos.d# mv CentOS-Vault.repo CentOS-Vault.repo.bak新建一个文件，名为：xiaofeng.repo 内容如下： xiaofengname=xiaofengbaseurl=file:/mnt 查找路径enable=1 是否检查GPG-KEY，0为不检查，1为检查gpgchack=0 是否启用yum源，0为不启用，1为启用rootCentOS6-EN yum.repos.d# vim xiaofeng.repo3.安装软件（gcc等）查找gcc:yum search gcc安装gcc: yum y install gcc rootCentOS6-EN /# yum search gccLoaded plugins: fastestmirror, securityLoading mirror speeds from cached hostfilexiaofeng | 4.0 kB 00:00 . = N/S Matched: gcc =compat-libgcc-296.i686 : Compatibility 2.96-RH libgcc librarygcc-c+.i686 : C+ support for GCCgcc-gnat.i686 : Ada 95 support for GCCgcc-java.i686 : Java support for GCCgcc-objc.i686 : Objective-C support for GCCgcc-objc+.i686 : Objective-C+ support for GCClibgcc.i686 : GCC version 4.4 shared support librarycompat-gcc-34.i686 : Compatibility GNU Compiler Collectioncompat-gcc-34-c+.i686 : C+ support for compatibility compilercompat-gcc-34-g77.i686 : Fortran 77 support for compatibility compilergcc.i686 : Various compilers (C, C+, Objective-C, Java, .)gcc-gfortran.i686 : Fortran supportlibgcj.i686 : Java runtime library for gcclibgcj-devel.i686 : Libraries for Java development using GCClibgcj-src.i686 : Java library sources from GCC4 previewlibgomp.i686 : GCC OpenMP v3.0 shared support librarylibmudflap.i686 : GCC mudflap shared support librarylibmudflap-devel.i686 : GCC mudflap support Name and summary matches only, use search all for everything.rootCentOS6-EN /# yum -y gccLoaded plugins: fastestmirror, securityNo such command: gcc.
