修改密码、设置远程登录。（只需在nn01上 ）
#1.检查是否存在mysql安装包
rpm -qa|grep -i mysql
---------------------------------
mysql-community-release-el7-5.noarch
mysql-community-common-5.6.48-2.el7.x86_64
mysql-community-client-5.6.48-2.el7.x86_64
mysql-community-server-5.6.48-2.el7.x86_64
mysql-community-libs-5.6.48-2.el7.x86_64
#2.若有安装包则全部删除
rpm -ev mysql-community-client-5.6.48-2.el7.x86_64
rpm -ev mysql-community-server-5.6.48-2.el7.x86_64
rpm -ev mysql-community-release-el7-5.noarch
rpm -ev mysql-community-common-5.6.48-2.el7.x86_64
rpm -ev mysql-community-libs-5.6.48-2.el7.x86_64
#3.查询并删除mysql安装目录
#查询
find / -name mysql
----------------------------------------------
/var/lib/mysql
/var/lib/mysql/mysql
/usr/lib64/mysql
#删除
rm -rf /var/lib/mysql
rm -rf /var/lib/mysql/mysql
rm -rf /usr/lib64/mysql
#4.删除配置文件 my.cnf
rm -rf /etc/my.cnf
#5.检查是否存在mariadb
rpm -qa | grep mariadb
-----------------------------------------------
mariadb-libs-5.5.60-1.el7_5.x86_64
#6.删除mariadb文件
rpm -e --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64
#7.安装wget下载器
yum install -y wget
#8.进入/opt/software目录，下载mysql
cd /opt/software
wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
#9.安装mysql
rpm -ivh mysql-community-release-el7-5.noarch.rpm
#10.安装mysql-server
yum install mysql-server -y
#11.修改mysql用户权限
chown -R root:root /var/lib/mysql
#12.设置登录密码和远程连接用户名密码
mysql -uroot -p （密码输入直接回车）
1.use mysql;
2.用户、密码登录设置
update user set password=password('1111') where user='root';
3.当前用户对数据库的所有 *** 作权限赋给root用户，设置远程访问密码 1111
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY "1111" WITH GRANT OPTION;
4.flush privileges;
5.exit;
#13.设置数据库编码utd8
vi /etc/my.cnf
追加内容：character-set-server=utf8
#14.重启mysql服务
service mysqld restart
拷贝jdbc驱动文件到/usr/share/java目录下（只需nn01节点执行）
#1.创建目标目录/usr/share/java mkdir /usr/share/java #2.拷贝jdbc驱动文件到该目录下,更名为mysql-connector-java.jar cd /opt/software/mysql-connector-java-5.1.47.jar /usr/share/java/mysql-connector-java.jar #3.远程拷贝目录文件/usr/share/java至其他节点 scp -r /usr/share/java/ root@cdh-nn02:/usr/share scp -r /usr/share/java/ root@cdh-nn03:/usr/share scp -r /usr/share/java/ root@cdh-dn04:/usr/share scp -r /usr/share/java/ root@cdh-dn05:/usr/share scp -r /usr/share/java/ root@cdh-dn06:/usr/shareCloudera Manager 安装 cdh-nn01上 *** 作即可

进入欢迎页面，继续。
接受条款，继续。
版本选择免费版，继续。
等待页面刷新，进入集群安装页面。
自定义集群名称。
选择集群组件可选主机。
设置Cloudera服务数据包。
JDK环境集群主机已进行安装，此处可以取消勾选。
SSH免密登录已设置完毕，此处进行登录凭证设置。
Agent安装。
集群服务安装。
选择自定义安装服务，我这里选择HDFS,Hive,Hue,Impala,Kudu,Oozie,Spark,YARN,Zookeeper。
角色分配：将所要安装的服务角色分配到集群各节点。
服务组件元数据信息存储：各个组件绑定到对应的mysql数据库表进行存储。
Clouder Manager集群安装完成，可访问主节点7180端口进行访问，集群主界面如下。
可选：配置数据安装目录，数据存储到数据盘挂载目录。
至此集群安装完毕。
