redhat 如何配置使用centos源進行yum安裝以及升級

標籤：

如何設定redhat使用centos源，可以藉助yum工具進行安裝各種所需的包，以及進行系統升級。
這裡設定的是redhat6.0 對應的centos版本也是6.0 核心版本是2.6.32-71.el6.x86_64
這裡base源設定的是163的鏡像站
而epel擴充源使用的則是sohu鏡像站



1.首先確認yum相關的rpm包，並卸載
rpm -aq|grep yum|xargs rpm -e --nodeps
2.下載163相關rpm 包

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-69.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastetmirror-1.1.30-30.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm

python-iniparse-0.3.1-2.1.el6.noarch.rpm
yum-3.2.29-69.el6.centos.noarch.rpm
yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm
需要注意的是，yum-3.2.29-69.el6.centos.noarch.rpm與yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm這兩個包需要一起安裝。
3.下載163源的設定檔
若/etc/yum.repos.d/下有別的檔案，最好先進行備份操作
若沒有直接
 wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
編輯此檔案：
將mirrorlist都注釋掉，添加baseurl

將所有的$releasever改為你的版本號碼6（註：這裡這所以要改6，是redhat6.0與centos6.0的核心版本一致）儲存退出
如果是64的系統要將$basearch這個改為x86_64

5測試，先清空yum緩衝
yum clean all

6.再產生新的緩衝
yum makecache

之後再用yum list來看看包，如果沒有問題就可以使用共網centos的yum源安裝了。

配置epel源
1.首先是安裝epel源
yum list |grep epel
或者直接下載：
wget http://mirrors.sohu.com/fedora-epel/epel-release-latest-6.noarch.rpm

2.安裝完成後，編輯epel.repo
與base源設定檔類似，也是將新的baseurl添加進去，將預設的baseurl fedoraproject.org注釋掉
需要確定的是找到確切的鏡像站的目錄

具體的設定檔如下：
[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
baseurl=http://mirrors.sohu.com/fedora-epel/6/x86_64/

#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
#gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
[epel-debuginfo]
name=Extra Packages for Enterprise Linux 6 - $basearch - Debug
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch/debug
baseurl=http://mirrors.sohu.com/fedora-epel/6/x86_64/
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-6&arch=$basearch
failovermethod=priority
enabled=0
#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
#gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=1

[epel-source]
name=Extra Packages for Enterprise Linux 6 - $basearch - Source
#baseurl=http://download.fedoraproject.org/pub/epel/6/SRPMS
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-6&arch=$basearch
baseurl=http://mirrors.sohu.com/fedora-epel/6/x86_64/

failovermethod=priority
enabled=0
#gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=1


然後編輯另外一個檔案epel-testing.repo
同樣的我們將檔案中預設的，mirrolist和baseurl都注釋掉，換上我們說是用的鏡像站的具體路徑

[epel-testing]
name=Extra Packages for Enterprise Linux 6 - Testing - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/testing/6/$basearch
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=testing-epel6&arch=$basearch
baseurl=http://mirrors.sohu.com/fedora-epel/testing/6/x86_64/
failovermethod=priority
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

[epel-testing-debuginfo]
name=Extra Packages for Enterprise Linux 6 - Testing - $basearch - Debug
#baseurl=http://download.fedoraproject.org/pub/epel/testing/6/$basearch/debug
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=testing-debug-epel6&arch=$basearch
baseurl=http://mirrors.sohu.com/fedora-epel/testing/6/x86_64/debug
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=1

[epel-testing-source]
name=Extra Packages for Enterprise Linux 6 - Testing - $basearch - Source
#baseurl=http://download.fedoraproject.org/pub/epel/testing/6/SRPMS
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=testing-source-epel6&arch=$basearch
baseurl=http://mirrors.sohu.com/fedora-epel/testing/6/x86_64/
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=1

配置完成後可以先查看源是否已經添加：
yum repolist
yum clean all && yum makecache

然後可以yum zabbix20-agented
