cdh未完成

個節點服務器：

sudo chmod 777 /etc/sysctl.conf
sudo sysctl -w vm.swappiness=10
sudo echo "vm.swappiness=10" >> /etc/sysctl.conf
sudo chmod 777  /sys/kernel/mm/transparent_hugepage/defrag 
sudo chmod 777  /sys/kernel/mm/transparent_hugepage/enabled 
sudo echo never > /sys/kernel/mm/transparent_hugepage/defrag
sudo echo never > /sys/kernel/mm/transparent_hugepage/enabled

安裝mariadb

在這裏插入代碼片

解壓clouder：

tar -zxvf cloudera-manager-centos7-cm5.14.1_x86_64.tar.gz -C /opt/

jar

wget -c https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.46.zip
unzip mysql-connector-java-5.1.46.zip
cp mysql-connector-java-5.1.46/mysql-connector-java-5.1.46.jar /opt/cm-5.14.1/share/cmf/lib/

將jar包傳給子節點的clouder：

scp mysql-connector-java-5.1.46/mysql-connector-java-5.1.46.jar slave1:/opt/cm-5.14.1/share/cmf/lib/
scp mysql-connector-java-5.1.46/mysql-connector-java-5.1.46.jar slave2:/opt/cm-5.14.1/share/cmf/lib/

給節點創建用戶：

sudo useradd --system --home=/opt/cm-5.14.1/run/cloudera-scm-server/ --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm

修改主機：

vim /opt/cm-5.14.1/etc/cloudera-scm-agent/config.ini

初始化數據庫：
