3 重置MySQL初始化数据
drop database cmf; drop user cmf@‘%‘; drop user amon@‘%‘; cm-server: create database cmf DEFAULT CHARACTER SET utf8; grant all on cmf.* TO ‘cmf‘@‘%‘ IDENTIFIED BY ‘Zj314XXX!‘; flush privileges; amon: create database amon DEFAULT CHARACTER SET utf8; grant all on amon.* TO ‘amon‘@‘%‘ IDENTIFIED BY ‘Zj314XXX!‘; flush privileges;
4 在hadoop001节点上，安装rpm包
cd /var/www/html/cm/5/RPMS/x86_64
yum install -y ./cloudera-manager-daemons-5.12.0-1.cm5120.p0.120.el7.x86_64.rpm
yum install -y cloudera-manager-server-5.12.0-1.cm5120.p0.120.el7.x86_64.rpm
