要搭建本地yum仓库首先需要明确的是都有哪些必备的步骤：
服务端
1. 需要将需要制作成仓库的软件的rpm包保存在本地
2. 需要通过createrepo软件制作仓库索引菜单
3. 需要通过ftp或http协议进行传输
1. 制作本地yum仓库的yum源文件
本地保存rpm包
有两种办法
其一：开启yum本地缓存
开启yum本地缓存后，所有通过yum安装的软件包，yum都会把rpm包保存到本地相应目录下
[root@yumcangku etc]# vim /etc/yum.conf
[main]
cachedir=/warehouse #这里是代表创建仓库的名字
keepcache=1 #这里的参数是设置是否开启本地缓存，0代表不开启，1代表开启
debuglevel=2
logfile=/var/log/yum.log
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
installonly_limit=5
bugtracker_url=http://bugs.centos.org/set_project.php?project_id=23&ref=http://bugs.centos.org/bug_report_page.php?category=yum
distroverpkg=centos-release
这里是yum本地缓存rpm包的路径
mkdir /warehouse
其二：通过yum命令只下载不安装
yum install --downloadonly --downloaddir=/warehouse mysql-server.server
--downloadonly 只下载不安装
--downloaddir 指定rpm包的下载路径
安装createrepo
createrepo用于生成repomd.xml。repomd.cml简单来说就是存放本地仓库rpm包的索引信息，我们的yum源就是根据这个文件来知道具体包的存放位置的
yum install createrepo -y
生成Rpm仓库索引
[root@yumcangku /]# createrepo /warehouse/
Spawning worker 0 with 95 pkgs
Workers Finished
Saving Primary metadata
Saving file lists metadata
Saving other metadata
Generating sqlite DBs
Sqlite DBs complete
每次加入新的rpm包，更新yum仓库
createrepo --update /warehouse/
服务端配置仓库局域网访问路径
通过http协议访问
[root@yumcangku /]# yum install nginx -y
[root@yumcangku /]# cd /etc/nginx/conf.d/
[root@yumcangku /]# vim local-basic.conf
server {
listen 12345;
server_name 10.0.0.61;
root /warehouse;
index index.html;
location / {
root /warehouse;
autoindex on;
autoindex_localtime on;
autoindex_exact_size off;
}
}
访问网址: http://10.0.0.61:12345/
通过ftp协议访问
[root@yumcangku /]# yum install vsftpd -y
[root@yumcangku conf.d]# systemctl start vsftpd
访问网址: ftp://10.0.0.61/pub/
客户端配置
yum客户端配置文件
http协议文件
cat warehouse.repo
[warehouse]
name=Server
baseurl=http://10.0.0.61:12345/
enable=1
gpgcheck=0
priority=1
ftp协议yum源配置文件
cat local-base-ftp.repo
[local-base]
name=Server
baseurl=ftp://10.0.0.61/pub/
enable=1
gpgcheck=0
priority=1
清yum缓存
yum clean all
查看yum源
[root@yumcangku /]# yum repolist
已加载插件：fastestmirror, security
Loading mirror speeds from cached hostfile
仓库标识 仓库名称 状态
local-base
yum源优先级
1.下载
yum install yum-plugin-priorities.noarch
2.启用插件
cat /etc/yum/pluginconf.d/priorities.conf
[main]
enabled = 1
3.修改本地Yum源优先使用
cat CentOS-Media.repo
[c7-media]
name=CentOS-$releasever - Media
baseurl=file:///media/cdrom/
gpgcheck=0
enabled=1
priority=1 #yum源优先级参数
CentOS-Base.repo
[base]
name=CentOS-$releasever - Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
priority=2 #yum源优先级参数
#released updates
[updates]
name=CentOS-$releasever - Updates
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
priority=2 #yum源优先级参数
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras

#baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
priority=2 #yum源优先级参数
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
priority=2 #yum源优先级参数
#contrib - packages by Centos Users
[contrib]
name=CentOS-$releasever - Contrib
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/contrib/$basearch/
gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
