1、CentOS本地源設置

1.備份並刪除原始的repo源文件html

[root@rd-proxy yum.repos.d]# tar -jcv -f CentOS.repo.tar.bz3 CentOS-*
CentOS-Base.repo
CentOS-Debuginfo.repo
CentOS-Media.repo
CentOS-Vault.repo
[root@rd-proxy 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

[root@rd-proxy yum.repos.d]# rm -f CentOS-*
[root@rd-proxy 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 linux

[root@rd-proxy yum.repos.d]# vi Centos-Base.repo
[local_server]
#定義庫名
name=This is a local repo
#定義描述
baseurl=file:///media/cdrom
#定義源路徑，可多個
enable=1
#是否啓用源,1真0假
gpgcheck=1
#是否檢查key，若不檢查則無需定義key
"Centos-Base.repo" 6L, 89C written

3.清除全部緩存sql

[root@rd-proxy yum.repos.d]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: local_server
Cleaning up Everything
Cleaning up list of fastest mirrors

4.重建本地緩存centos

[root@rd-proxy yum.repos.d]# yum makecache
Loaded plugins: fastestmirror

local_server                                                                                                                   | 5.0 kB     00:00 ...

local_server/primary_db                                                                                                        | 4.5 MB     00:00 ... 
local_server/other_db                                                                                                          | 2.0 MB     00:00 ...

#2、局域網yum源配置服務器

1.所需工具
createrepo：倉庫文件建立工具
httpd，ftp：傳輸工具curl

2.環境準備
server：ikulin 10.10.10.1
client：localhost 10.10.10.3
linux：centos7ide

3.server拷貝光盤rpm包到本地http目錄工具

[linxy@ikulin media]$ cp -r Packages/ /var/www/html/yum

4.server生成建立倉庫測試

[linxy@ikulin 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啓動httpd服務

[linxy@ikulin html]$ sudo systemctl restart httpd

6.client配置repo源 

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

7.client清除全部緩存 

[root@localhost 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重建本地緩存(失敗)

8.1.故障1，防火牆設置問題

[root@localhost 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. 故障提示沒有route沒法鏈接到server，但在server上測試訪問爲ok，連通性測試爲ok，判斷爲防火牆攔截了訪問請求
  2. 檢查c/s的selinux、iptables爲關閉，但centos7開始，默認的防火牆爲firewalld，查詢狀態爲開啓
  3. 關閉server的firewalld服務後出現故障2

8.2.故障2，http目錄權限設置問題

[root@localhost 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. 故障提示訪問拒絕，使用curl訪問服務器ok，向下級目錄訪問被拒絕，判斷爲目錄或文件訪問權限設置不正確
  2. 檢查yum下倉庫數據目錄repodata的權限爲744，非所屬用戶訪問只擁有隻讀權限，而目錄必須擁有執行權限才能進入
  3. 修改repodata目錄權限爲745 
    [linxy@ikulin yum]$ ll -d  rep*
drwxr--r-- 2 root root 4096 Feb 16 22:47 repodata
[linxy@ikulin yum]$ sudo chmod 745 repodata/
[linxy@ikulin yum]$ ll -d  rep*
drwxr--r-x 2 root root 4096 Feb 16 22:47 repodata

    8.3.client本地緩存重建完成
