本地yum仓库与局域网yum仓库配置

一、CentOS本地源设置

1.备份并删除原始的repo源文件

[[email protected] yum.repos.d]# tar -jcv -f CentOS.repo.tar.bz3 CentOS-*
CentOS-Base.repo
CentOS-Debuginfo.repo
CentOS-Media.repo
CentOS-Vault.repo
[[email protected] yum.repos.d]# ll
total 21
-rw-r--r--  2 root root 2294 Oct 30 19:06 CentOS-Base.repo
-rw-r--r--. 2 root root  638 Feb 25  2013 CentOS-Debuginfo.repo
-rw-r--r--  2 root root  630 Oct 30 19:03 CentOS-Media.repo
-rw-r--r--  2 root root 1579 Oct 30 19:12 CentOS.repo.tar.bz2
-rw-r--r--. 2 root root 3664 Feb 25  2013 CentOS-Vault.repo

[[email protected] yum.repos.d]# rm -f CentOS-*
[[email protected] yum.repos.d]# ll
total 5
-rw-r--r-- 2 root root 1579 Oct 30 19:12 CentOS.repo.tar.bz2

2.新建repo文件

[[email protected] yum.repos.d]# vi Centos-Base.repo
[local_server]
#定义库名
name=This is a local repo
#定义描述
baseurl=file:///media/cdrom
#定义源路径，可多个
enable=1
#是否启用源,1真0假
gpgcheck=1
#是否检查key，若不检查则无需定义key
"Centos-Base.repo" 6L, 89C written

3.清除所有缓存

[[email protected] yum.repos.d]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: local_server
Cleaning up Everything
Cleaning up list of fastest mirrors

4.重建本地缓存

[[email protected] yum.repos.d]# yum makecache
Loaded plugins: fastestmirror

#二、局域网yum源配置

1.所需工具
createrepo：仓库文件创建工具
httpd，ftp：传输工具

2.环境准备
server：ikulin 10.10.10.1
client：localhost 10.10.10.3
linux：centos7

3.server拷贝光盘rpm包到本地http目录

[[email protected] media]$ cp -r Packages/ /var/www/html/yum

4.server生成创建仓库

[[email protected] yum]$ createrepo .
Spawning worker 0 with 2398 pkgs
Spawning worker 1 with 2398 pkgs
Spawning worker 2 with 2398 pkgs
Spawning worker 3 with 2397 pkgs
Workers Finished
Saving Primary metadata
Saving file lists metadata
Saving other metadata
Generating sqlite DBs
Sqlite DBs complete

5.server启动httpd服务

[[email protected] html]$ sudo systemctl restart httpd

6.client配置repo源

[[email protected] yum.repos.d]# cat CentOS-Base.repo
[C7]
name=CentOS7
baseurl=http://10.10.10.1/yum
gpgcheck=0

7.client清除所有缓存

[[email protected] yum.repos.d]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: C7
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos
Cleaning up list of fastest mirrors

8.client重建本地缓存(失败)

8.1.故障1，防火墙设置问题

[[email protected] yum.repos.d]# yum makecache
Loaded plugins: fastestmirror
http://10.10.10.1/yum/repodata/repomd.xml: [Errno 14] curl#7 - "Failed connect to 10.10.10.1:80; No route to host"
Trying other mirror.
^Chttp://10.10.10.1/yum/repodata/repomd.xml: [Errno 14] curl#56 - "Callback aborted"

故障排除：

  1. 故障提示没有route无法连接到server，但在server上测试访问为ok，连通性测试为ok，判断为防火墙拦截了访问请求
  2. 检查c/s的selinux、iptables为关闭，但centos7开始，默认的防火墙为firewalld，查询状态为开启
  3. 关闭server的firewalld服务后出现故障2

8.2.故障2，http目录权限设置问题

[[email protected] yum.repos.d]# yum makecache
Loaded plugins: fastestmirror
http://10.10.10.1/yum/repodata/repomd.xml: [Errno 14] HTTP Error 403 - Forbidden

故障排除：

  1. 故障提示访问拒绝，使用curl访问服务器ok，向下级目录访问被拒绝，判断为目录或文件访问权限设置不正确
  2. 检查yum下仓库数据目录repodata的权限为744，非所属用户访问只拥有只读权限，而目录必须拥有执行权限才能进入
  3. 修改repodata目录权限为745 
    [[email protected] yum]$ ll -d  rep*
drwxr--r-- 2 root root 4096 Feb 16 22:47 repodata
[[email protected] yum]$ sudo chmod 745 repodata/
[[email protected] yum]$ ll -d  rep*
drwxr--r-x 2 root root 4096 Feb 16 22:47 repodata

    8.3.client本地缓存重建完成

本地yum仓库与局域网yum仓库配置的相关文章

centos7创建本地源并搭建局域网yum源服务器

关于局域网yum源仓库的搭建

1.#输入命令rmp -q -vsftpd,查看是否安装了该包. 2.#创建挂载点,把光盘挂载到该点 3.#使用命令用rpm-ivh 安装vsftpd安装包 4.#启动vsftpd服务,设为下次开机启动. 5.#输入ifconfig,找到自己的局域网地址,看是否连接超时,如果超时就是没关闭防火墙的原因,那么就关闭防火墙.(学习环境中关闭防火墙就行了,不支持实际工作环境中关闭). 6.#用浏览器访问自己的局域网地址 ,会出现以下页面,说明ftp服务配置成功. 7.#创建文件夹,将CentOS7安装

一.安装软件包的三种方法 rpm工具.yum工具.源码包 RPM工具:是以一种数据库记录的方式将需要的套件安装到Linux主机的一套管理程序.就是说,你的Linux系统中有一个关于RPM的数据库,它记录了安装的包以及包与包之间的依赖关系.RPM包是预先在Linux机器上编译并打包的文件,安装快捷.缺点:安装环境必须与编译时的环境一致或相当,包与包之间存在着相互依赖的情况,卸载包时需先把依赖的包卸载.若依赖的包是系统必需的,就不能卸载这个包,否则系统崩溃. yum工具:优势:可联网下载所需要的RP

安装软件包的三种方法 、rpm包介绍、rpm工具用法、yum工具用法、yum搭建本地仓库安装软件包的

安装软件包的三种方法rpm包类似于windows的exe文件.rpm工具可以安装rpm包,安装路径和文件名都是固定好的,不需要过多的设置.yum也可以安装rpm包,比rpm工具好的一点是支持自动安装依赖的包.源码包主要是源代码,需要谁用编译器编译成可执行的文件.·····rpm包介绍首先我们要把光盘连接到linux系统进行挂载,打开vmware运行虚拟机,然后右键右下角的光盘的图标然后点连接,然后在系统里挂载,挂载点可以自己选,我们使用命令:mount /dev/cdrom /mnt/把光盘挂载
