Install 【EPEL】 if you haven't already.
yum -y install http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm yum install epel-release
使用Redhat/CentOS系统光盘作为yum仓库
1,挂载系统iso光盘到本地 前提是系统iso文件已经复制到本地文件系统 root~魂斗罗~# ll -h CentOS-6.8-x86_64-bin-DVD1.iso -rw-r--r--. 1 root root 3.7G Sep 27 20:33 CentOS-6.8-x86_64-bin-DVD1.iso #mkdir /mnt/iso #mount -o loop -t iso9660 ./CentOS-6.8-x86_64-bin-DVD1.iso /mnt/iso 2,备份repo文件 root~魂斗罗~# mkdir repo root~魂斗罗~# mv /etc/yum.repos.d/* ./repo/ root~魂斗罗~# cp repo/CentOS-Media.repo /etc/yum.repos.d/ root~魂斗罗~# ll /etc/yum.repos.d/ total 4 -rw-r--r--. 1 root root 630 Sep 27 20:12 CentOS-Media.repo 3,修改Media.repo root~魂斗罗~# vim /etc/yum.repos.d/CentOS-Media.repo 只修改3处 baseurl=file:///mnt/iso/ gpgcheck=0 enabled=1 root~魂斗罗~# 4,测试安装 root~魂斗罗~# yum clean all root~魂斗罗~# yum list root~魂斗罗~# yum install -y gcc
【163】 源的使用
yum -y install wget(确保系统存在wget) cd /etc/yum.repos.d rm -rf ./* wget http://mirrors.163.com/.help/CentOS5-Base-163.repo(适用于CentOS5) wget http://mirrors.163.com/.help/CentOS6-Base-163.repo(适用于CentOS6) wget http://mirrors.163.com/.help/CentOS7-Base-163.repo(适用于CentOS7) yum clean all yum makecache 测试: yum install gcc -y
yum 命令使用一直报错
Loaded plugins: fastestmirror, security Determining fastest mirrors Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again
解决方法
yum clean all yum info kernel
or any other yum command as a test. If that doesn't work you can try Code:
yum clean all rm -f /var/lib/rpm/__db* rpm --rebuilddb
then try any yum command again.
yum list
OK ！
保存 yum包
[root@admin-node ~]# cat /etc/yum.conf [main] cachedir=/var/cache/yum/$basearch/$releasever keepcache=1
查看系统版本：
/etc/debian_version lsb_release -a uname -rm
http://mirrors.163.com/.help/ubuntu.html
下载与系统匹配的源
apt-get update
http://mirrors.163.com/.help/debian.html
下载与系统匹配的源
apt-get update
apt-get update 和 upgrade 的区别
update 是同步 /etc/apt/sources.list 和 /etc/apt/sources.list.d 中列出的源的索引，这样才能获取到最新的软件包。
upgrade 是升级已安装的所有软件包，升级之后的版本就是本地索引里的，因此，在执行 upgrade 之前一定要执行 update, 这样才能是最新的。
