3.添加RPM-GPG-KEY-EPEL

---

centos7

curl https://mirrors.tuna.tsinghua.edu.cn/epel/RPM-GPG-KEY-EPEL-7 > /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

---

centos6

curl https://mirrors.tuna.tsinghua.edu.cn/epel/RPM-GPG-KEY-EPEL-7 > /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

4. 安装epel

yum install epel-release

5. 从新生成缓存

yum clean all
yum makecache

注：如果遇到GPG key retrieval failed这种提示 把CentOS-Base.repo中gpgcheck=1改成gpgcheck=0
