（一）CM部分在线安装
master上安装：
cloudera-manager-daemons
cloudera-manager-agent oracle-jdk-1.7
cloudera-manager-installer.bin
>>yum install -y cloudera-manager-daemons-5.7.4-1.cm574.p0.9.el6.x86_64.rpm
>>yum install -y cloudera-manager-agent-5.7.4-1.cm574.p0.9.el6.x86_64.rpm
>>chmod 0777 cloudera-manager-installer.bin
>>yum clean all(记住清空，否则可能下周最新版本)
./cloudera-manager-installer.bin（这里会在线下载除cloudera-manager-daemons核 cloudera-manager-agent及 oracle-jdk-1.7之外的包，因为这三个包较大，所以先提前下载安装）
slave上安装 ：
cloudera-manager-agent-5.7.4-1.cm574.p0.9.el6.x86_64.rpm
cloudera-manager-daemons-5.7.4-1.cm574.p0.9.el6.x86_64.rpm
oracle-j2sdk1.7-1.7.0+update67-1.x86_64.rpm
（二）CDH的离线安装
提前把parcel三个文件放到/root/download下：
登录7180端口,设置远程url：https://archive.cloudera.com/cdh5/parcels/5.7.4/ 防止更新到最新版本
（如要代理相应修改parcel目录）
