Linux基礎入門教程-RHEL7.4之YUM更換CentOS源

1.配置YUM本地源

1.掛載映象

[root@linuxidc ~]# mount /dev/cdrom /mnt

2.檢視是否掛載成功

[root@linuxidc ~]# df -h

Filesystem      Size  Used Avail Use% Mounted on

/dev/sda3        49G  1.3G 48G 3% /

devtmpfs        479M   0  479M 0% /dev

tmpfs         489M   0  489M 0% /dev/shm

tmpfs         489M  6.6M  482M 2% /run

tmpfs         489M   0  489M 0% /sys/fs/cgroup

/dev/sda1     497M  112M  385M  23% /boot

tmpfs            98M   0 98M 0% /run/user/0

/dev/sr0        3.8G  3.8G   0 100% /mnt

3.備份原來的倉庫

[root@linuxidc ~]# cp -r /etc/yum.repos.d /etc/yum.repos.d_bak

[root@linuxidc ~]# rm -f /etc/yum.repos.d/*

4.建立新的repo配置檔案

[root@linuxidc ~]# vi /etc/yum.repos.d/dvd.repo

[dvd]

name=install dvd

baseurl=file:///mnt

enabled=1

gpgcheck=0

5.重新整理repos生成快取

[root@linuxidc ~]# yum makecache

Loaded plugins: product-id, search-disabled-repos, subscription-manager

This system is not registered with an entitlement server. You can use subscription-manager to register.

Metadata Cache Created

2.使用CentOS源

1.解除安裝紅帽yum

[root@linuxidc Packages]# rpm -e $(rpm -qa | grep yum) --nodeps

[root@linuxidc Packages]# echo $?

0

2.刪除yum相關檔案

[root@linuxidc Packages]# rm -rf /etc/yum.conf

[root@linuxidc Packages]# rm -rf /etc/yum.repos.d/*

[root@linuxidc Packages]# rm -rf /var/cache/yum

3.下載CentOS相關yum元件

[root@linuxidc ~]#

4.建立新的repo檔案

[base]

name=CentOS-7 - Base

baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/7/os/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=os

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#released updates

[updates]

name=CentOS-7 - Updates

baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/7/updates/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=updates

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that may be useful

[extras]

name=CentOS-7 - Extras

baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/7/extras/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=extras

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that extend functionality of existing packages

[centosplus]

name=CentOS-7 - Plus

baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/7/centosplus/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=centosplus

gpgcheck=1

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

5.使用yum makecache重新整理生成快取

[root@linuxidc ~]# yum makecache

Loaded plugins: fastestmirror, product-id, search-disabled-repos, subscription-manager

This system is not registered with an entitlement server. You can use subscription-manager to register.

Metadata Cache Created

6.epel擴充套件源

首先從CentOS Extras這個源（tuna也有映象）裡安裝epel-release：

yum install epel-release -y

編輯epel.repo

[epel]

name=Extra Packages for Enterprise Linux 7 - $basearch

baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/7/$basearch

#mirrorlist=https://mirrors.Fedoraproject.org/metalink?repo=epel-7&arch=$basearch

failovermethod=priority

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

[epel-debuginfo]

name=Extra Packages for Enterprise Linux 7 - $basearch - Debug

baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/7/$basearch/debug

#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-7&arch=$basearch

failovermethod=priority

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

gpgcheck=1

[epel-source]

name=Extra Packages for Enterprise Linux 7 - $basearch - Source

baseurl=https://mirrors.tuna.tsinghua.edu.cn/epel/7/SRPMS

#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-7&arch=$basearch

failovermethod=priority

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

gpgcheck=1

這些做完以後要刪除/etc/pki/rpm-gpg/的檔案

把epel中新的檔案下載放入其中

[root@linuxidc ~]# ls /etc/pki/rpm-gpg/

RPM-GPG-KEY-EPEL-7

RPM-GPG-KEY-CentOS-7
