搭建 centos7 YUM 源

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
