redhat6.4 安装epel源和aliyun的源

##下载阿里云的源

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

修改阿里云的系统版本

sed -i ‘s/$releasever/6/g‘ CentOS-Base.repo

然后就可以使用了阿里云的源了

##下载epel的源

wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

rpm -ivh epel-release-6-8.noarch.rpm

源于epel的源，需要注意一下就几点：

1.can not connection to metalink?

解决：

vi /etc/yum.repos.d/epel.repo

将第三行的注释打开，将第四行的注释掉，即：

[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

2.http://download.fedoraproject.org/pub/epel/6/x86_64/repodata/de6a02cff57c89b6ccb3c8d3d8700f9616af988510c36d6c2f1d18ad36bbd04b-comps-el6.xml.bz2: [Errno 14] problem making ssl connection

尝试其他镜像。

尝试其他镜像。

错误：failure: repodata/1c39425dc34eee21f07f32b9b374f8775f8b72d1020b6ac56ab5c631f7a38a65-filelists.sqlite.bz2 from epel: [Errno 256] No more mirrors to try.

如果报上面的错：

1.将epel的enable 的1 改为0

2.yum install ca-certificates

3.将epel的enable 的0 改为1

ok可以使用了
