# 搭建 centos7 YUM 源 #

## 1. 创建yum软件保存目录 ##

[root@localhost ~]# mkdir -p /www/share/yum

## 2. 修改yum配置文件 ##

1.  先备份yum配置文件
    
        [root@localhost ~]# cp /etc/yum.conf /etc/yum.conf.bak
2.  修改yum配置文件中yum软件包保存目录并开启rmp包缓存功能
    
        [root@localhost ~]# vim /etc/yum.conf
    
        [main]
        #cachedir=/var/cache/yum/$basearch/$releasever
        cachedir=/www/share/yum/$basearch/$releasever
        keepcache=1

## 3. 安装createrepo和http ##

1.  createrepo 命令用于创建yum源（软件仓库），即为存放于本地特定位置的众多rpm包建立索引，描述各包所需依赖信息，并形成元数据。
    
        [root@localhost ~]# yum install createrepo httpd -y

## 4. 创建http共享目录 ##

[root@localhost ~]# vim /etc/httpd/conf.d/share.conf

#http share
    Alias /share /www/share
    <Directory "/www/share">
        Options Indexes FollowSymLinks
        IndexOptions NameWidth=* DescriptionWidth=* FoldersFirst
        IndexOptions SuppressIcon HTMLTable Charset=UTF-8 SuppressHTMLPreamble
        Order allow,deny
        Allow from all
        Require all granted
    </Directory>

## 5. 修改http配置文件 ##

1.  备份httpd配置并修改配置文件
    
        [root@localhost ~]# cp /etc/httpd/conf/httpd.conf{,.bak}
    
        [root@localhost ~]# echo "
        ServerName localhost
        #关闭版本号显示
        ServerSignature Off
        ServerTokens Prod
        ">>/etc/httpd/conf/httpd.conf

## 6. 启动http服务 ##

[root@localhost ~]# systemctl enable httpd.service && systemctl restart httpd.service

[root@localhost ~]# netstat -antp|grep 'httpd'

## 7. 访问 http 服务 ##

1.  浏览器访问192.168.92.60/share ,能访问即正常
2.  如果不能访问可尝试关闭防火墙
    
        [root@localhost ~]# systemctl stop firewalld.service
3.  若果出现403错误，可以尝试调整selinux，或者关闭。
    
        [root@localhost ~]# setenforce 0

## 8. 创建YUM软件仓库 ##

[root@localhost ~]# mkdir -p /www/share/centos7_rpm
    [root@localhost ~]# createrepo -p /www/share/centos7_rpm/
    Saving Primary metadata
    Saving file lists metadata
    Saving other metadata
    Generating sqlite DBs
    Sqlite DBs complete
    [root@localhost ~]# ll /www/share/centos7_rpm/
    total 4
    drwxr-xr-x 2 root root 4096 Jun 19 09:40 repodata

## 9. 创建源文件 ##

1.  创建源文件，baseurl换成自己ip地址

[root@localhost ~]# echo "
    [My_share]
    name=My_Souce
    baseurl=http://192.168.92.60/share/centos7_rpm/
    gpgcheck=0
    enabled=1
    cost=88
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
    ">/www/share/Lan7.repo

## 10. 下载软件包 ##

1.  将yum缓存的rpm包拷贝到/www/share/centos7\_rpm/
    
        [root@localhost ~]# find /www/share/yum -name *.rpm |sed -r 's#.*#mv & /www/share/centos7_rpm/\n#'|bash
2.  下载没有安装过的包
    
        [root@localhost ~]# yum install --downloadonly --downloaddir=/www/share/centos7_rpm/ -y 包名称
3.  重新下载已经安装过的包
    
        [root@localhost ~]# yum reinstall --downloadonly --downloaddir=/www/share/centos7_rpm/ -y 包名称
4.  更新源
    
        [root@localhost ~]# createrepo --update -p /www/share/centos7_rpm/
5.  创建rpm下载、yum更新shell
    
        [root@localhost ~]# echo '#!/bin/sh
        [ $# = 0 ] && { 
        echo "更新源"
        /usr/bin/createrepo --update -p /www/share/centos7_rpm/
        } || { 
        echo "yum下载"
        yum install --downloadonly --downloaddir=/www/share/centos7_rpm/ -y $*
        echo "更新源"
        /usr/bin/createrepo --update -p /www/share/centos7_rpm/
        }
        '>yumd.sh
    
        [root@localhost ~]# ln -s $(pwd)/yumd.sh /usr/bin/yumd
    
        [root@localhost ~]# chmod +x yumd.sh

执行 yumd 更新源，执行 yumd 软件1 软件2 ，就会下载相关软件并更新源

## 11. 下载OpenStack安装包 ##

1.  仅作为参考，根据需求添加其它组件
    
        [root@localhost ~]# yum install centos-release-openstack-queens -y #安装OpenStack官方源
        [root@localhost ~]# yum install --downloadonly --downloaddir=/www/share/centos7_rpm/ -y \
        python-openstackclient openstack-selinux python-openstackclient python2-PyMySQL \
        openstack-utils \
        mariadb mariadb-server mariadb-galera-server python2-PyMySQL \
        erlang socat rabbitmq-server \
        openstack-keystone httpd mod_wsgi memcached python-memcached \
        apr apr-util \
        openstack-glance python-glance \
        openstack-nova-api openstack-nova-conductor \
        openstack-nova-console openstack-nova-novncproxy \
        openstack-nova-scheduler openstack-nova-placement-api \
        openstack-nova-compute python-openstackclient openstack-selinux \
        openstack-neutron openstack-neutron-ml2 \
        openstack-neutron-linuxbridge python-neutronclient ebtables ipset \
        openstack-neutron-linuxbridge ebtables ipset \
        openstack-dashboard \
        openstack-cinder targetcli python-keystone lvm2 \
        corosync pacemaker pcs fence-agents resource-agents \
        openstack-neutron-linuxbridge
2.  更新源
    
        [root@localhost ~]# createrepo --update -p /www/share/centos7_rpm/

## 12. 客户端使用源 ##

1.  下载服务端源文件到本地
    
        [root@localhost ~]# wget -O /etc/yum.repos.d/Lan7.repo http://192.168.92.60/share/Lan7.repo
2.  客户端测试，查看源名称为myshare说明正常
    
        [root@localhost ~]# yum install httpd
