Centos7.1搭建本地Yum仓库(Centos6&7&epel)

1.系统环境准备

[root@zon ~]# cat /etc/redhat-release && uname -r
CentOS Linux release 7.1.1503 (Core) 
3.10.0-229.el7.x86_64
[root@zon ~]# getenforce && systemctl status firewalld;hostname -I
Disabled
firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled)
   Active: inactive (dead)

192.168.56.12 

2.安装createrepo

[root@zon ~]# yum install createrepo -y
================================================================================================
 Package                     Arch               Version                  Repository        Size
================================================================================================
Installing:
 createrepo                  noarch             0.9.9-28.el7             base              94 k
Installing for dependencies:
 deltarpm                    x86_64             3.6-3.el7                base              82 k
 python-deltarpm             x86_64             3.6-3.el7                base              31 k

Transaction Summary
================================================================================================
Install  1 Package (+2 Dependent packages)

3.创建相关目录及更改配置

#创建本地yum仓库repo发布目录(rpm包存放目录)
[root@zon ~]# mkdir /data/local_yum_data -p
#创建本地yum仓库同步目录
[root@zon Packages]# mkdir /data/local_yum_data/centos/6/os/x86_64/ -p
[root@zon Packages]# mkdir /data/local_yum_data/centos/6/extras/x86_64/ -p
[root@zon Packages]# mkdir /data/local_yum_data/centos/6/updates/x86_64/ -p
[root@zon Packages]# mkdir /data/local_yum_data/epel/6/x86_64/ -p

4.提供yum服务(Http:80)

#可以用Apache或nginx提供web服务，适用于内网环境
##基于HTTP的yum源配置
#安装apache软件
    yum install -y httpd
    vim /etc/httpd/conf/httpd.conf
#将默认的www目录指向本地创建的yum仓库目录
    [root@zon data]# grep -v "#" /etc/httpd/conf/httpd.conf
    ServerRoot "/etc/httpd"
    Listen 80
    Include conf.modules.d/*.conf
    User apache
    Group apache
    ServerAdmin root@localhost
    ServerName 192.168.56.12:80
    <Directory />
        AllowOverride none
        Require all denied
    </Directory>
    DocumentRoot "/data/local_yum_data/"
    <Directory "/data/local_yum_data/">
        AllowOverride None
        Require all granted
    </Directory>
    <Directory "/data/local_yum_data/">
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
    </Directory>
 #修改/usr/local/yumrepo目录的属主和属组为apache
    chown -R apache.apache /data/yum_data/
#删除默认主页
    rm /etc/httpd/conf.d/welcome.conf
#启动服务
    #service httpd restart

浏览器输入http本机IP，显示出列表文件

利用python快速搭建http服务，提供yum服务

    cd /data/local_yum_data/ && nohup python -m SimpleHTTPServer 80 &>/dev/null &

5.同步官方rpm包文件

5.1 Centos-6同步官方rpm包文件

    #官方源(centos6)
    rsync -av rsync://mirrors.ustc.edu.cn/centos/6/os/x86_64/ /data/local_yum_data/centos/6/os/x86_64/
    rsync -av rsync://mirrors.ustc.edu.cn/centos/6/extras/x86_64/ /data/local_yum_data/centos/6/extras/x86_64/
    rsync -av rsync://mirrors.ustc.edu.cn/centos/6/updates/x86_64/ /data/local_yum_data/centos/6/updates/x86_64/
    rsync -av --exclude=debug rsync://mirrors.ustc.edu.cn/epel/6/x86_64/ /data/local_yum_data/epel/6/x86_64/

5.2 Centos-7同步官方rpm包文件

    #官方源(centos6)
    rsync -av rsync://mirrors.ustc.edu.cn/centos/7/os/x86_64/ /data/local_yum_data/centos/7/os/x86_64/
    rsync -av rsync://mirrors.ustc.edu.cn/centos/7/extras/x86_64/ /data/local_yum_data/centos/7/extras/x86_64/
    rsync -av rsync://mirrors.ustc.edu.cn/centos/7/updates/x86_64/ /data/local_yum_data/centos/7/updates/x86_64/
    rsync -av --exclude=debug rsync://mirrors.ustc.edu.cn/epel/7/x86_64/ /data/local_yum_data/epel/7/x86_64/

5.3 初始化repodata索引文件

    #初始化repodata索引文件
    [root@zon ~]# createrepo -h
    [root@zon ~]# createrepo -pdo /data/local_yum_data/ /data/local_yum_data/
    Saving Primary metadata
    Saving file lists metadata
    Saving other metadata
    Generating sqlite DBs
    Sqlite DBs complete

6.客户端yum源指定
