================== 为Redhat5配置网易的yum源
网易开源的镜像站 ：http://mirrors.163.com/
根据的你的Redhat的版本，选择相应的Centos的源路径
我的OS是x86_64 Redhat5，对应的rpm路径 http://mirrors.163.com/centos/5/os/x86_64/
导入证书（证书的位置 http://mirrors.163.com/centos/）
rpm -import http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-5
使用网易的源（参考 http://mirrors.163.com/.help/centos.html 注意备份旧的文件）
cd /etc/yum.repos.d/
wget http://mirrors.163.com/.help/CentOS5-Base-163.repo
修改文件（把所有$releasever替换成5，保存 ）
vim CentOS5-Base-163.repo
更新yum
yum makecache
yum -y update
--------------------如何查看CentOS版本方法
有以下命令可以查看：
# lsb_release -a
LSB Version: :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch
Distributor ID: CentOS
Description: CentOS release 5.4 (Final)
Release: 5.4
Codename: Final
这个命令适用于所有的linux，包括Redhat、SuSE、Debian等发行版。
root@MyMail ~ # uname
Linux
root@MyMail ~ # uname -r
2.6.18-164.el5
以下二种方法适用于RedHat,CentOS
root@MyMail ~ # cat /etc/redhat-release
CentOS release 5.4 (Final)
登录到linux执行rpm -q redhat-release
#rpm -q redhat-release
或CentOS
root@MyMail ~ # rpm -q centos-release
centos-release-5-4.el5.centos.1
cat /proc/version
uname -r
uname -a
yum -v
其中CentOS-Base.repo记录着网络上的yum源的地址和路径信息等
CentOS-Media.repo记录着可以从本地作为yum源的介质和路径
#yum list installed | grep yum
yum.noarch 3.2.22-20.el5.centos installed
yum-fastestmirror.noarch 1.1.16-13.el5.centos installed
yum-metadata-parser.i386 1.1.2-3.el5.centos installed
yum-updatesd.noarch 1:0.9-2.el5 installed
#yum update --skip-broken
You can try it like this:
yum update --skip-broken
这个是我刚碰到的问题!
yum remove xorg-x11-drv-joystick 这样不行的话在
yum remove xorg-x11-drivers-7.1-4.1.el5.i386
http://centos.ustc.edu.cn/ 推荐
http://linux.vbird.org/linux_server/0210network-secure.php#update_how
-------------------------------------安装后请按照以下步骤修改CenOS-Base.repo,以后就可以方便的用yum安装软件了.
cd /etc/yum.repos.d
mv CentOS-Base.repo CentOS-Base.repo.save
wget http://centos.ustc.edu.cn/CentOS-Base.repo
修改以上文件后, 如需要安装gcc, 直接yum install gcc就可以了
为Centos5添加网易163、搜狐的yum源
cd /etc/yum.repos.d/
wget http://mirrors.163.com/.help/CentOS-Base-163.repo
wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo
yum makecache
yum update
更新现有的包命令是:
yum update

yum命令用ctrl+z命令中断后，再运行yum时，出现：
Existing lock /var/run/yum.pid: another copy is running as pid 3046.
Another app is currently holding the yum lock; waiting for it to exit...
Another app is currently holding the yum lock; waiting for it to exit...

NND，说我正在使用yum。输入
rm -f /var/run/yum.pid
/sbin/service yum-updatesd restart
Stopping yum-updatesd: [ OK ]
Starting yum-updatesd: [ OK ]
好了，一切正常了
