扩展步骤：
- 准备环境：jdk-1.8、python-2.7、修改hosts环境、安装ntp、关闭防火墙
- 建目录，并将parcel-repo的包拷贝过来
| --/opt
|--/cloudera
|--/parcels
|--/parcel-repo
|--/CDH-5.15.1-1.cdh5.15.1.p0.4-xenial.parcel
|--/CDH-5.15.1-1.cdh5.15.1.p0.4-xenial.parcel.sha
|--/manifest.json
|--/cm-5.15.1
- 拷贝压缩包
cloudera-manager-xenial-cm5.15.1_amd64.tar.gz，解压：tar -zxf cloudera-manager-xenial-cm5.15.1_amd64.tar.gz -C /opt
注意：此处不能偷懒直接用线上已解压好的，不然CDH界面会出现节点相互替换显示的情况。始终不会显示全部节点 - 保险起见我还是安装了下面包（暂不知作用）
apt-get install libmysqlclient-dev
# pip install mysql-python
apt-get install python-lxml
apt-get install apache2
- 安装mysql-connector-java包：
apt-get install libmysql-java - 软连接：
ln -s /usr/share/java/mysql-connector-java.jar /opt/cm-5.15.1/share/cmf/lib/mysql-connector-java.jar - 创建用户
cloudera-scm
sudo useradd --system --home=/opt/cloudera-manager/cm-5.15.1/run/cloudera-scm-server --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm - 启动节点
cd /opt/cm-5.15.1/etc/init.d
./cloudera-scm-agent start
9.界面安装
主机 -> 向集群添加新主机

问题1解决办法2：
解决方法1对我无效，在尝试多次后，重启了节点网络后生效了
sudo /etc/init.d/networking restart 注意，此处是针对ubuntu系统的命令
