[root@yum-server ~]# yum install -y wget make cmake gcc gcc-c++ pcre-devel zlib-devel openssl openssl-devel createrepo yum-utils

yum-utils：reposync同步工具

createrepo：編輯yum庫工具

plugin-priorities：控制yum源更新優先級工具，這個工具可以用來控制進行yum源檢索的先後順序，建議可以用在client端。

注：由于很多人喜歡最小化安裝，上邊軟體是一些常用環境。

[root@yum-server ~]# mkdir /mirrors/

[root@yum-server ~]# reposync -r base -p /mirrors/

注：不用擔心沒有建立相關目錄，系統自動建立相關目錄，并下載下傳，時間較長請耐心等待。

可以用 repo -r --repoid=repoid指定要查詢的repo id，可以指定多個（# reposync -r base -p /mirror #這裡同步base目錄到本地）

createrepo文法：

格式：createrepo -po  源目錄  索引中繼資料的輸出位置目錄

[root@yum-server ~]# createrepo -po /mirrors/base/  /mirrors/base/

[root@yum-server ~]# createrepo -po /mirrors/epel/  /mirrors/epel/

[root@yum-server ~]# createrepo --update /mirrors/base

[root@yum-server ~]# createrepo --update /mirrors/epel
