Yum源仓库
下载其他更快的yum源
中科大的yum源：
wget http://centos.ustc.edu.cn/CentOS-Base.repo
163的yum源：
wget http://mirrors.163.com/.help/CentOS-Base-163.repo
http://mirrors.163.com/.help/CentOS6-Base-163.repo
sohu的yum源
wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo
阿里的yum源
CentOS 6
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
或者
curl -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
一、示例更换阿里云yum源
阿里云 CentOS
1、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
或者
curl -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
或者
curl -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
或者
curl -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
二、示例配置网易163的yum源
1. 下载repo文件
下载地址：http://mirrors.163.com/.help/CentOS6-Base-163.repo
2. 备份并替换系统的repo文件
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost ~]# mv CentOS-Base.repo CentOS-Base.repo.bak
[root@localhost ~]# mv /root/CentOS6-Base-163.repo CentOS-Base.repo
3. 执行yum源更新
[root@localhost ~]# yum clean all
[root@localhost ~]# yum makecache
[root@localhost ~]# yum update
4. 到此已结束，用yum安装一下文件，看是否OK
[root@localhost ~]# yum install vim*
5. 安装centos常用的软件包及工具
常见压缩工具 zip unzip bzip2
[root@localhost ~]# yum -y install unzip zip bzip2 bzip2-devel
gcc gcc++编译器
[root@localhost ~]# yum install gcc gcc-c++ -y
cmake编译器
[root@localhost ~]# yum install cmake make -y
图片资源
[root@localhost ~]# yum -y install gd libjpeg libjpeg-devel libpng libpng-devel freetype-devel
其它常用资源包工具
[root@localhost ~]# yum -y install autoconf bison automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel*
