CentOS 7.0本地yum源地址及 配置yum地址优先级

 

首先附上本地centos7.0yun源基础地址及epel源地址:
vi /etc/yum.repos.d/CentOS-local.repo
添加如下内容:
[base-local] 
name=CentOS-local 
baseurl=http://192.168.1.200/yum/centos/7.0/os/x86_64 
gpgcheck=0 
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 
priority=1 

[updates-local] 
name=CentOS-local 
baseurl=http://192.168.1.200/yum/centos/7.0/updates/x86_64 
gpgcheck=0 
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 
priority=1
 
vi /etc/yum.repos.d/CentOS-local-epel.repo
添加如下内容:
[base-local-epel] 
name=CentOS-local 
baseurl=http://192.168.1.200/yum/epel/centos/7.0/os/x86_64/
gpgcheck=0 
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 
priority=1 
 

 

1.安装yum-plugin-priorities包

# yum install yum-plugin-priorities
 
 
 

2.修改/etc/yum.repos.d目录中的CentOS-Base.repo、CentOS-local.repo的优先级

//直接加上priority=N即可

 

附CentOS-Base.repo文件的配置:

附CentOS-local.repo文件的配置

 

由上图可以看出本地yum源优先级比官网base源高,因此在yum安装包时,首先会在本地查找,没有找到才会去官网查找。

 

4、验证:

yum clean all
yum install vim

 

上图显示vim的rpm包在本地base-local源中查找。

 

备注:

1、要使priority参数有效,必须安装yum-plugin-priorities插件
2、N为整型数.默认优先级为99.数值越小优先级越高;
