Redhat7 是 Centos7的發行版本,因版權問題在使用yum會提示需註冊(就是要花錢ing);node
咱們轉而使用Centos7源替代;python

準備:win主機*一、Redhat最小化安裝企業版*1less
一、Xshell ssh連接redhat,並切換到root帳戶(後續按照等操做都在Xshell界面進行)ssh
#這個比較簡單,通常redhat ssh開機自啓,ps命令能直接查看

二、win主機打開http://mirrors.163.com/centos/7/os/x86_64/Packages/,Ctrl+F查找wget並下載到本地,直接連接:wget-1.14-10.el7_0.1.x86_64.rpmthis
三、使用WinSCP,以root登陸redhaturl
四、將下載的wget-1.14-10.el7_0.1.x86_64.rpm 傳到/tmp目錄
五、安裝wget
cd /tmp rpm -ivh wget-1.14-10.el7_0.1.x86_64.rpm
六、卸載redhat自帶的yum
rpm -qa | grep yum | xargs rpm -e --nodeps
注:a、xargs是一條Unix和類Unix操做系統的經常使用命令。它的做用是將參數列表轉換成小塊分段傳遞給其餘命令,以免參數列表過長的問題
b、--nodeps 強制卸載,無論依賴性
七、下載centos的yum安裝包,路徑同2,能夠直接使用下列連接
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-125.el7.centos.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-29.el7.noarch.rpm
注意:安裝包都在不斷更新,請按照包名本身匹配,當前可用2015-11。
八、安裝以上下載包
rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm rpm -ivh yum-3.4.3-125.el7.centos.noarch.rpm yum-plugin-fastestmirror-1.1.31-29.el7.noarch.rpm
[注] :最後2個須要一塊兒安裝,不然會出現依賴性錯誤
九、下載repo文件,注意切換目錄
固然你能夠簡單點,直接將10中的repo複製,並在yum.repos.d目錄新建*******.repo文件
cd /etc/yum.repos.d/ wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
十、編輯CentOS7-Base-163.repo文件,將其中的$releasever更改成centos的版本號7
此步驟建議下載到本機,使用記事本或notepad打開一鍵替換,再使用winscp上傳到redhat
repo參考:
# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-7 - Base - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=os baseurl=http://mirrors.163.com/centos/7/os/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-7 - Updates - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=updates baseurl=http://mirrors.163.com/centos/7/updates/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-7 - Extras - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=extras baseurl=http://mirrors.163.com/centos/7/extras/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-7 - Plus - 163.com baseurl=http://mirrors.163.com/centos/7/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7
十一、yum clean all 清除原有緩存
十二、yum makecache 獲取yum列表
出現下面提示,表示yum更改完成:
Metadata Cache Created
1三、yum repolist能夠查看源數據
yum repolist repo id repo name status !base/x86_64 CentOS-7 - Base - 163.com 8,652 !extras/x86_64 CentOS-7 - Extras - 163.com 275 !updates/x86_64 CentOS-7 - Updates - 163.com 1,707 repolist: 10,634
