yum私有仓库的实现及博客输出

1. 创建局域网的基于Base的私有yum源

1.1. 说明

centos的base包可以从系统镜像中获取或者第三方平台获取

1.2. repo仓库配置文件

[repositoryID]
name=Some name for this repository
baseurl=url://path/to/repository/
enabled={1|0}
gpgcheck={1|0}
gpgkey=URL
enablegroups={1|0}
failovermethod={roundrobin|priority}
roundrobin：意为随机挑选，默认值
priority:按顺序访问
cost= 默认为1000

1.3. 前期准备

#挂载光盘CentOS-8.5.2111-x86_64-dvd1.iso

1.4. 操作步骤：

1.4.1. yum服务器4种baseurl形式

file:///var/www/html/CD_Centos8.5
http://
https://
ftp://

1.4.2. 方法1file形式访问

[01:19:00 root@localhost ~]#mkdir /var/www/html/CD_Centos8.5
[01:28:19 root@localhost ~]#mount /dev/sr0 /var/www/html/CD_Centos8.5
mount: /var/www/html/CD_Centos8.5: WARNING: device write-protected, mounted read-only.
 
[01:59:19 root@localhost yum.repos.d]#cat Centos8-base.repo 
# 2. CentOS-Base.repo
#
# 3. The mirror system uses the connecting IP address of the client and the
# 4. update status of each mirror to pick mirrors that are updated to and
# 5. geographically close to the client.  You should use this for CentOS updates
# 6. unless you are manually picking other mirrors.
#
# 7. If the mirrorlist= does not work for you, as a fall back you can try the 
# 8. remarked out baseurl= line instead.

2. 搭建第三方阿里云extras私有yum源

2.1. 下载阿里云的extras源

[02:44:02 root@localhost yum.repos.d]#yum reposync --repoid=extras --download-metadata -p /var/www/html/centos/
[02:44:19 root@localhost yum.repos.d]#ls /var/www/html/centos/

2.2. 配置阿里云yum源文件

[02:24:39 root@localhost yum.repos.d]#cat Centos-8.repo 
# 10. CentOS-Base.repo
#
# 10. The mirror system uses the connecting IP address of the client and the
# 10. update status of each mirror to pick mirrors that are updated to and
# 10. geographically close to the client.  You should use this for CentOS updates
# 10. unless you are manually picking other mirrors.
#
# 10. If the mirrorlist= does not work for you, as a fall back you can try the 
# 10. remarked out baseurl= line instead.
