CentOS7.2卸载完CDH5.12后重装CDH

1因为是重装很多环境ok

　　A mysql环境ok

　　B 防火墙ok

　　C hostname绑定也没有问题

　　D jdk也是ok

　　E root用户，所以不涉及权限，如果不是请设置sudo权限用户

　 F ntp服务正常

　　G httpd服务正常

　　H 本地yum源配置正常

　　I mysql连接驱动之前也有没有删除，正常 cd /usr/share/java/ 3台机器都有

2 检查自己的软件包ok,之前设置过

　　 http://172.24.8.138/cm/5

　　http://172.24.8.138/parcels/

下面是外网访问截图，上面ip内网，也可以curl一下，在各个机器上

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

5 配置数据库

vim /etc/cloudera-scm-server/db.properties
