epel yum源

1、安装EPEL YUM源

        安装之前使用 yum repolist 命令查看最后一行的yum源软件数量。

        Centos 6 版本：

                kernel：http://mirrors.kernel.org/fedora-epel/epel-release-latest-6.noarch.rpm

                阿里云：https://mirrors.aliyun.com/epel/epel-release-latest-6.noarch.rpm

        Centos 7 版本：

                kernel：http://mirrors.kernel.org/fedora-epel/epel-release-latest-7.noarch.rpm

                阿里云：https://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm

        使用方法：

                下载：wget  http://mirrors.kernel.org/fedora-epel/epel-release-latest-6.noarch.rpm

                安装：rpm -Uvh epel-release-latest-6.noarch.rpm

        直接安装：

                rpm --import https://mirrors.aliyun.com/epel/RPM-GPG-KEY-EPEL-7

                rpm -i https://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm

阿里云epel源：

        epel(RHEL 7)

                 wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

        epel(RHEL 6)

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

        epel(RHEL 5)

                 wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-5.repo

2、校验是否安装成功

        使用 yum repolist 查看是否安装成功。

        我们增加了EPEL源，该源有12199个软件。

        yum源目录位置/etc/yum.repos.d/

阿里云yum源：developer.aliyun.com/mirror 

        curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

        sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo

Docker源：developer.aliyun.com/mirror/docker-ce 

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache fast
yum -y install docker-ce

快捷命令：

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo && \
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo && \
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo && \
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

nginx repo：

cat > /etc/yum.repos.d/nginx.repo <<EOF
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
EOF
