【Centos7.6安裝CDH6.1.0】手把手教你搭建CDH6.1.0
主節點安裝本地yum倉庫中的CM組件
root用戶下，在mini1上執行：
# 安裝組件
yum -y install cloudera-manager-server
yum -y install cloudera-manager-agent
yum -y install cloudera-manager-daemons
# 開機自啓
systemctl enable cloudera-scm-server
systemctl enable cloudera-scm-agent
從節點安裝本地yum倉庫中的CM組件
root用戶下，在mini2、mini3上分別執行:
# 安裝組件
yum -y install cloudera-manager-agent
yum -y install cloudera-manager-daemons
# 開機自啓
systemctl enable cloudera-scm-agent
初始化scm數據庫
/opt/cloudera/cm/schema/scm_prepare_database.sh mysql -h mini1 --scm-host mini1 scm scm 1QAZ@wsx
效果如下：
[root@mini1 ~]# /opt/cloudera/cm/schema/scm_prepare_database.sh mysql -h mini1 --scm-host mini1 scm scm 1QAZ@wsx
JAVA_HOME=/home/hadoop/apps/jdk1.8.0_191
Verifying that we can write to /etc/cloudera-scm-server
Creating SCM configuration file in /etc/cloudera-scm-server

Sat Feb 01 02:58:46 CST 2020 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

啓動CM服務
root用戶下，在mini1上執行：
systemctl start cloudera-scm-server
若機器性能不太好，執行該命令後需要耐心等待一段時間。
