我是靠谱客的博主唠叨黑夜，这篇文章主要介绍配置本地yum源，现在分享给大家，希望可以做个参考。

配置本地yum源

- - - 2. Centos6.5.配置本地yum源
    - - 2.1. 更换Centos6.5的yum源配置
      - 2.1.1. 使用阿里云开源镜像站
        2.1.2. 使用清华大学开源镜像站

2. Centos6.5.配置本地yum源

复制代码

本文同步阿里/清华大学的开源镜像站，同步到本地进行搭建本地yum源，并非使用挂载方式。

2.1. 更换Centos6.5的yum源配置

复制代码

1
2
3
[yangqi@second ~]$ cd /etc/yum.repos.d/
[yangqi@second yum.repos.d]$ ll

可以看到自己的目录下有很多的.repo结尾的文件，将这些文件进行备份。

复制代码

1
2
[yangqi@second yum.repos.d]$ sudo rename .repo .repo.bak *.repo

使用sudo之前，必须要给普通用户配置sudo的权限，如果不会配置，我之后会分享

指令解析：将.repo改为.repo.bak，匹配文件名为*.repo，表示以所有的repo结尾的文件

2.1.1. 使用阿里云开源镜像站

阿里云： https://opsx.alibaba.com/mirror

复制代码

1

3
# 如果使用阿里云开源镜像站，可以使用curl
[yangqi@second yum.repos.d]$ sudo crul -O http://mirrors.aliyun.com/repo/Centos-6.repo

下载完成之后，可以看到自己的/etc/yum.repos.d/目录下多了一个Centos-6.repo文件

为了方便期间，可以将名字更名为Aliyun.repo

复制代码

1
2
[yangqi@second yum.repos.d]$ sudo rename Centos-6.repo Aliyun.repo

之后可以使用sudo yum clean all将之前的yum清空一下，显示如下类似信息即可

复制代码

[yangqi@second yum.repos.d]$ sudo yum clean all
Loaded plugins: fastestmirror, refresh-packagekit, security
Cleaning repos: localrepo
Cleaning up Everything
[yangqi@second yum.repos.d]$ yum list

在这里插入图片描述

使用yum list查看是否可以查看yum源仓库的所有rpm安装包，如果可以访问，则这一步已经成功

接下来，开始下载阿里云开源镜像站的所有的rpm包到本地磁盘

建议：新建一个目录，存放要下载的所有的rpm包，建议在/opt/yum/centos/6/os/，如果没有可以自行创建此目录

复制代码

1
2
3
[yangqi@second yum.repo.d]$ cd /opt/yum/centos/6/os/
[yangqi@second os]$ ll

此时目录为空，做好了所有的准备工作

在这里插入图片描述

在/opt/yum/centos/6/os/目录下创建/x86_64/目录，建立索引

复制代码

1
2
[yangqi@second os]$ sudo mkdir x86_64/

使用createrepo指令创建索引，如果和我的一样，没有，先进行安装

复制代码

[yangqi@second os]$ createrepo
-bash: createrepo: command not found
[yangqi@second os]$ yum list all | grep createrepo
createrepo.noarch                       0.9.9-18.el6                   localrepo
[yangqi@second os]$ sudo yum -y install createrepo.noarch

在这里插入图片描述

最后显示如下，则表示安装成功

在这里插入图片描述

接下来创建索引

复制代码

1
2
3
[yangqi@second os]$ sudo createrepo /opt/yum/centos/6/os/x86_64/

在这里插入图片描述

这样，索引已经建立成功，开始搞事情（网速一定要跟得上），不要像我一样，龟速

复制代码

1
2
3
[yangqi@second os]$ reposync -r base -p /opt/yum/centos/6/os/x86_64

第一次同步可能比较慢，需要耐心等待，等同步完之后可以将索引再重新更新一次

复制代码

1
2
3
[yangqi@second os]$ sudo createrepo --update /opt/yum/centos/6/os/x86_64/

下载完成后，准备配置使用本地yum源

进入这个目录，使用apache服务器进行配置

复制代码

1
2
3
[yangqi@second os]$ cd /var/www/html/

确保电脑开启了httpd服务，并且已经关闭了防火墙

建议：最好将httpd服务设置为开机自启，防火墙设置为永久关闭

复制代码

# 检查防火墙状态
[yangqi@second html]$ chkconfig iptables --list
# 关闭防火墙
[yangqi@second html]$ sudo service iptables stop
# 设置防火墙开机自启为off
[yangqi@second html]$ sudo chkconfig iptables off
# 检查httpd服务状态
[yangqi@second html]$ chkconfig httpd status
# 开启httpd服务
[yangqi@second html]$ sudo service httpd start
# 设置httpd服务开机自启
[yangqi@second html]$ sudo chkconfig httpd on

在这里插入图片描述

创建软链接，指向/opt/yum/centos/6/os/x86_64

复制代码

1
2
3
[yangqi@second html]$ sudo ln -s /opt/yum/centos/6/os/x86_64/ localrepo

在这里插入图片描述

清空缓存数据

复制代码

1
2
3
[yangqi@second html]$ sudo yum clean all

使用vi编辑local.repo文件

复制代码

1
2
3
4
# 切换回/opt/yum/centos/6/os/
[yangqi@second os]$ sudo vi local.repo

这里的ipaddress写自己作为本地yum源的那台机器的ip地址即可

后面的验证方式，暂时先取消，设置为0，否则校验不通过没法安装

复制代码

1

[localrepo]
name=localrepo
failovermethod=priority
baseurl=http://ipaddress/localrepo
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

因为只开了一台虚拟机，所以就用这台进行测试，如果你开了多太，可以将这个文件发送到另一台虚拟机，放到/etc/yum.repos.d/目录下，将其余的yum全部备份，操作步骤一样

复制代码

[yangqi@second os]$ sudo cp localrepo.repo /etc/yum.repos.d/
[yangqi@second os]$ cd /etc/yum.repos.d/
[yangqi@second yum.repos.d]$ ll
[yangqi@second yum.repos.d]$ sudo mv Aliyun.repo Aliyun.repo.bak
[yangqi@second yum.repos.d]$ sudo yum clean all

在这里插入图片描述

执行yum list，如果显示所有的rpm来源为localrepo，就是刚才localrepo.repo文件中的[localrepo]，则表示成功

复制代码

1
2
3
[yangqi@second yum.repos.d]$ yum list

至此，基于阿里云的本地yum源搭建完成

2.1.2. 使用清华大学开源镜像站

清华大学开源镜像站： https://mirrors.tuna.tsinghua.edu.cn/

只需要修改几步，即可。清华大学开源镜像站，没有现成的.repo文件，可以自己在/etc/yum.repos.d/目录下新建一个Tsinghua.repo

复制代码

1
2
3
[yangqi@second yum.repos.d]$ sudo touch Tsinghua.repo

输入以下内容，其余的步骤和使用阿里云开源镜像站一样
