Linux下的第三方yum源配置
引言:
CentOS自带的yum源中rpm包数量有限,很多时候找不到我们需的软件包,(例如:要安装网络连接查看软件iftop,默认设置下无法使用yum命令安装),下面教大家在CentOS 6.2中(以32位系统为例,64位系统安装方法一样),使用第三方yum源来安装更多软件包。
使用 yum repolist 命令可以查看系统已经安装好的yum源
注意:下载第三方的yum源的安装包的时候要注意看自己的系统是多少位的:
查看linux机器是32位还是64位的方法:
file /sbin/init 或者 file /bin/ls
/sbin/init: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped
如果显示 64-bit 则为64位;
file /sbin/init
/sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), stripped
如果显示为32 bit 则为32bit;
uname -a:
uname -a
Linux pmx002**.**.** 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
x86_64表示64位机器
uname -a
Linux pmx0**.**.** 2.6.9-5.ELsmp #1 SMP Wed Jan 5 19:30:39 EST 2005 i686 i686 i386 GNU/Linux
一、安装CentOS yum源优先级插件yum-priorities
yum -y install yum-priorities //(该插件的作用主要是设置调用源时的优先级的,一般将官方的优先级设置为最高)
二、设置CentOS默认yum源的优先级为最高:(如果不设置优先级安装多个Yum源的话可能存在冲突的问题。)
cd /etc/yum.repos.d/ #进入yum源目录
vi CentOS-Base.repo #在[base]、[updates]、[extras]组下面添加priority=1,在[centosplus]、[contrib]组下面添加priority=2

###############################################################
备注:priority的优先级为1到99,设置为1即优先级最高,1-10为系统保留,第三方yum源的优先级从11-99
三、安装epel yum源:
64位的epel源下载地址:
wget http://download.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
32位的epel源下载地址:
rpm -ivh http://download.fedora.redhat.com/pub/epel/6/i386/epel-release-6-5.noarch.rpm
导入key认证文件:(如果gpgcheck=0则就不需要这步骤)
参数mirrorlist表示的是映射yum容器的url路径(对应的url路径为多个)此路径需要yum程序自行去查找链接地址,如果不适用可以注释掉。
baseurl表示的是YUM容器的实际地址是一个固定的地址。如果不使用的话也可以注释掉。
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
vi /etc/yum.repos.d/epel.repo #修改epel yum源优先级,priority=11
###############################################################
[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
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

四、安装rpmforge yum源
wget http://apt.sw.be/redhat/el6/en/i386/rpmforge/RPMS/rpmforge-release-0.5.2-2.el6.rf.i686.rpm

rpm --import RPM-GPG-KEY.dag.txt
rpm -ivh rpmforge-release-0.5.2-2.el6.rf.i686.rpm
vi /etc/yum.repos.d/rpmforge.repo #修改rpmforge yum源优先级,priority=12

#################################################################
五、安装rpmfusion yum源
rpm -ivh http://download1.rpmfusion.org/free/el/updates/testing/6/i386/rpmfusion-free-release-6-0.1.noarch.rpm
vi /etc/yum.repos.d/rpmfusion-free-updates-testing.repo #修改rpmfusion yum源优先级,priority=13
