Centos如何配置epel、webtatic 的yum源
To set up the repository, install the webtatic-release RPM:
Webtatic EL7 for CentOS/RHEL 7:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpmWebtatic EL6 for CentOS/RHEL 6:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm还有个简便方法， 可以直接安装对应的epel源
yum -y install epel-release查看源仓库的信息
yum repolist刷新本地缓存，实测epel的yum缓存下载较慢，耐心等待或者科学上网
