yum与apt-get的区别以及两者更新源(阿里/网易【163】)
一般来说著名的linux系统基本上分两大类:
1.RedHat系列:Redhat、Centos、Fedora等
2.Debian系列:Debian、Ubuntu等
RedHat 系列
1 常见的安装包格式 rpm包,安装rpm包的命令是“rpm -参数”
2 包管理工具 yum
3 支持tar包
Debian系列
1 常见的安装包格式 deb包,安装deb包的命令是“dpkg -参数”
2 包管理工具 apt-get
3 支持tar包
apt-get更新源
在使用apt-get update的时候,出现如下错误时:
E: Some index files failed to download, they havebeen ignored, or old ones used instead.
可以将目录下/var/lib/apt/lists/partial/所有的文件清掉,再次运行apt-get update即可!
1、复制原文件备份
sudo cp /etc/apt/source.list /etc/apt/source.list.bak
2、编辑源列表文件
sudo vim /etc/apt/source.list
3、将原来的列表删除,添加如下内容

4、运行sudo apt-get update
5、运行sudo apt-get upgrade
yum更新源
1、复制原文件备份
mv /etc/yum.repos.d/CentOS-Base.repo/etc/yum.repos.d/CentOS-Base.repo.backup
2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/
CentOS 5
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
CentOS 6
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
CentOS 7
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
3、之后运行yum makecache生成缓存
