jdk（所有节点）

卸载自带的jdk-open
rpm -qa | grep java
rpm -qa | grep jdk - yum -y remove xxjdk   #删除所有的jdk
yum remove -y *jdk*
yum remove -y *java*

rpm  -ivh jdk-8u202-linux-x64.rpm

yum  install   java -y

数据库安装

卸载原有的mariadb
rpm -qa | grep mariadb #查看安装信息
rpm --nodeps -e  `rpm -qa | grep mariadb`
安装数据库顺序  最好解压安装
tar -xf mysql-5.7.21-1.el7.x86_64.rpm-bundle.tar
首先安装（其他节点也需要安装，同时也安装 mysql-community-libs-compat-5.7.21-1.el7.x86_64.rpm ）

yum install net-tools  -y  #安装net-tools包
yum install perl -y        #安装perl包

安装顺序
rpm -ivh mysql-community-common-5.7.21-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.21-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.21-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.21-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-compat-5.7.21-1.el7.x86_64.rpm(compat解决hue数据库连接不上)   比较重要(其他节点都要安装)
rpm -ivh mysql-community-devel-5.7.21-1.el7.x86_64.rpm                                   #安装mysqlclient需要用到

yum  install  mysql-community-common  -y
yum  install  mysql-community-libs  -y
yum  install  mysql-community-client   -y
yum  install  mysql-community-libs-compat  -y
yum  install  mysql-community-server   -y
yum  install  mysql-community-devel  -y

启动mysql
systemctl start mysqld
systemctl enable mysqld
systemctl daemon-reload

查看root初始密码
cat /var/log/mysqld.log |grep password

#vi /etc/my.cnf
在[mysqld]的段中加上一句：skip-grant-tables
例如：
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
skip-grant-tables 

USE mysql 修改密码;
ALTER USER 'root'@'localhost' IDENTIFIED BY 'xx.com';
FLUSH PRIVILEGES;

mysql -uroot -pxx.com

登录mysql数据库
mysql -uroot –p密码 # 密码为上一步看到的
首先，修改validate_password_policy参数的值

set global validate_password_policy=0;
set global validate_password_length=2;
set global validate_password_special_char_count=0;
set global validate_password_mixed_case_count=0;
set global validate_password_number_count=0;
set password = password('daxxx.com');

查看密码策略:
SHOW VARIABLES LIKE 'validate_password%';

授权用户远程连接
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'xxx.com' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'cdh'@'%' IDENTIFIED BY 'xxx.com' WITH GRANT OPTION;

set global validate_password_policy=0;
set global validate_password_length=2;
set global validate_password_special_char_count=0;
set global validate_password_mixed_case_count=0;
set global validate_password_number_count=0;

grant all privileges on *.* to 'scm'@'localhost' identified by 'scm' with grant option;
grant all privileges on *.* to 'scm'@'127.0.0.1' identified by 'scm' with grant option;
grant all privileges on *.* to 'scm'@'%' identified by 'scm' with grant option;

grant all privileges on *.* to 'root'@'localhost' identified by 'xxxx.com' with grant option;
grant all privileges on *.* to 'root'@'127.0.0.1' identified by 'dxx.com'  with grant option;
grant all privileges on *.* to 'root'@'%' identified by 'xxa.com'  with grant option;

grant all privileges on *.* to 'cdh'@'localhost' identified by 'dxx.com' with grant option;

flush privileges;

CM安装

[root@foo-1 yum.repos.d]# cat  cloudera-manager.repo
[clouderamanager]
name=Cloudera Manager
baseurl=http://192.168.2.113/cm-5.13.3/
gpgkey=http://192.168.2.113/cm-5.13.3/RPM-GPG-KEY-cloudera
enabled = 1
gpgcheck = 0

install the Cloudera Manager packages.
在管理节点安装cloudera-manager-daemons cloudera-manager-server
#RHEL, if you have a yum repo configured
sudo yum install cloudera-manager-daemons cloudera-manager-server
sudo yum install cloudera-manager-agent

#On all hosts, run the following command to install the Cloudera Manager agent:
在子节点，安装管理客户端
sudo yum install cloudera-manager-daemons cloudera-manager-agent

*** 在所有节点修改管理代理连接管理服务器的主机名
On all hosts, configure the Cloudera Manager Agent to point to the Cloudera Manager Server by setting the following properties in the /etc/cloudera-scm-agent/config.ini configuration file:
server_host	Name of the host where Cloudera Manager Server is running.
server_port	Port on the host where Cloudera Manager Server is running.

sed -i 's/server_host=localhost/server_host=cdh-1/'  /etc/cloudera-scm-agent/config.ini 

数据库连接程序

初始化  yum安装的scm_prepare_database.sh 位置
 mkdir  /usr/share/java/  &&  cd   /usr/share/java/

curl   -O    http://192.168.2.113/mysql-connector-java/mysql-connector-java-5.1.46.tar.gz

mkdir  /usr/share/java/
cp    mysql-connector-java-5.1.46-bin.jar    mysql-connector-java.jar
chmod  755  mysql-connector-java-5.1.46-bin.jar    mysql-connector-java.jar

cp  mysql-connector-java-5.1.46-bin.jar    mysql-connector-java.jar     /usr/share/cmf/lib/
mkdir   /usr/share/java/

初始化数据库：
/usr/share/cmf/schema/scm_prepare_database.sh   mysql cm  -hlocalhost  -uroot   -pxxxx.com   --scm-host cdh-1  scm scm  scm

所有节点运行管理代理
管理节点
      systemctl start cloudera-scm-server
      systemctl start cloudera-scm-agent

判断是否启动成功
find  / -name   cloudera-scm-server.log
tail  -f  /var/log/cloudera-scm-server/cloudera-scm-server.log
grep "Started Jetty server"    cloudera-scm-server.log

子节点
systemctl start cloudera-scm-agent

安装后节点也需要安装
cd    /usr/share/cmf/lib/
mv   /usr/share/java/mysql-connector-java-5.1.46-bin.jar  .

cdh 也需要驱动
scp  mysql-connector-java-5.1.46-bin.jar   foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib

 hive 数据库也需要
scp  mysql-connector-java-5.1.46-bin.jar   foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib/hive/lib
scp  mysql-connector-java-5.1.46-bin.jar   foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib
scp  mysql-connector-java-5.1.46-bin.jar   foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib/hive/lib
scp  mysql-connector-java-5.1.46-bin.jar   foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib/oozie/lib
scp  mysql-connector-java-5.1.46-bin.jar   foo-2:/opt/cloudera/parcels/CDH-5.13.3-1.cdh5.13.3.p0.2/lib/hue/lib
scp  mysql-connector-java-5.1.46-bin.jar   foo-2:/var/lib/oozie
scp  mysql-connector-java-5.1.46-bin.jar   foo-2:/var/lib/hue
