配置CDH源

配置CDH本地源

由于cdh的在线yum源网络情况太差，所以最好选择配置本地源进行安装，这样可以节省大量时间

下载相关离线yum软件包

http://archive.cloudera.com/cdh5/repo-as-tarball/

比如cdh5.10安装包cdh5.10.0-centos7.tar.gz就可以了

安装nginx

nginx安装方法

配置nginx做为yum本地源

将刚才下载的cdh软件包解压到/usr/share/nginx/html/

新建cdh/cloudera-cdh5.repo

[cloudera-cdh5]
# Packages for Cloudera's Distribution for Hadoop, Version 5, on RedHat    or CentOS 7 x86_64
name=Cloudera's Distribution for Hadoop, Version 5
baseurl=http://node-01/cdh/5/
gpgkey = http://node-01/cdh/RPM-GPG-KEY-cloudera
gpgcheck = 1

启动nginx

nginx

在各个节点上配置本地yum源

wget http://node-01/cdh/cloudera-cdh5.repo
sudo cp cloudera-cdh5.repo /etc/yum.repos.d/

node-01为nginx安装的节点计算机名

配置CDH在线源

wget https://archive.cloudera.com/cdh5/one-click-install/redhat/7/x86_64/cloudera-cdh-5-0.x86_64.rpm
sudo yum --nogpgcheck localinstall cloudera-cdh-5-0.x86_64.rpm
sudo yum clean all
sudo rpm --import https://archive.cloudera.com/cdh5/redhat/7/x86_64/cdh/RPM-GPG-KEY-cloudera
