CentOS7基于http方式搭建本地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

先备份yum配置文件，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 ~]# cp /etc/yum.conf /etc/yum.conf.bak
[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

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@yumrepo www]# 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

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'

浏览器访问192.168.92.60/share ,能访问即正常
这里写图片描述

7.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

8.创建源文件

[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

9.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

10.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

createrepo --update -p /www/share/centos7_rpm/

11.客户端使用源

1.下载服务端源文件到本地

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

yum install httpd
