Redhat 6.2 配置使用epel 和 163 yum源來安裝saltstack過程
由於紅帽線上yum更新需要註冊,沒有註冊redhat的機器,更新會提示 This system is not registered with RHN.
由於需要安裝saltstack,可以先配置epel源。到官網下載對應紅帽系統版本的yum源安裝包
rpm -ivh epel-release-6-8.noarch.rpm 安裝。
匯入key:
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
配置EPEL YUM源
在rhel中執行命令:
#yum repolist
報錯:
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again
解決過程:
安裝了epel-release-6-8.noarch.rpm以後,會在/etc/yum.repos.d目錄下,新增兩個檔案:
epel.repo #這是標準的epel源,經過測試,並且比較穩定的
epel-testing.repo #這是最新的,正在測試階段。
預設情況下,yum會搜尋/etc/yum.repos.d目錄下所有的檔案,搜尋其中的yum 源。搜尋的前提是enable=1,如果是enable=0就不搜尋該源了。
經過對比發現,上述錯誤中的epel,表示在epel.repo中發現問題。
開啟epel.repo後發現
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
將其修改為:
baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
即可。
由於本地光碟和epel源沒有 PyYAML ,所以安裝saltstack仍然不成功,配置網易163的yum源即可。
網上存在文章說需要解除安裝yum,安裝centos來配置網易163的yum源,我操作時,可以直接配置163源來使用,沒有做前3步。
一、需要刪除RHEL原有的yum
rpm -aq|grep yum|xargs rpm -e --nodeps #刪除
二、然後下載新的yum安裝包 #這裡我們使用CentOS的yum源
三、安裝yum軟體包
rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-14.1.el6.i686.rpm
rpm -ivh yum-3.2.27-14.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm
注意:最後兩個安裝包要放在一起同時安裝,否則會提示相互依賴,安裝失敗。
四、更改yum源 #我們使用網易的CentOS映象源
cd /etc/yum.repos.d/
wget
http://mirrors.163.com/.help/CentOS6-Base-163.repo
vi CentOS6-Base-163.repo #編輯檔案
把檔案裡面的$releasever全部替換為版本號,即6 最後儲存!
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

yum clean all #清理yum快取
yum makecache #將伺服器上的軟體包資訊快取到本地,以提高搜尋安裝軟體的速度
yum install vim* #測試yum是否可用
至此,Redhat6可以使用CentOS的yum源線上安裝軟體了!
