CDH6.2.0安装（三）

Step10: 上传安装文件

Step11: 检查文件是否正确

1. 确保cloudera-manager.repo文件放入/etc/yum.repos.d/目录
2. 确保parcel目录下文件完整

Step12: 安装jdk&CM

1. 验证repo文件是否起效

yum list | grep cloudera
#如果列出的不是待安装的版本，执行下面命令重试
yum clean all
yum list | grep cloudera

2. 切换到jdk&cm目录下，执行

yum -y install *.rpm

3. 设置java路径：

vi /etc/profile# 在该文件末尾添加以下行
export JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera/
export PATH=$JAVA_HOME/bin:$PATH

4. 检查安装：

java -version

Step13: 安装数据库(mysql)

需要用到数据库的组件：
Cloudera Manager Server
Cloudera Management Service roles:
Activity Monitor 
Reports Manager
Cloudera Navigator Audit Server
Cloudera Navigator Metadata Server
Hue
Each Hive metastore
Oozie

参考

1. 安装mysql数据库服务器(master)

wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
sudo yum update
sudo yum -y install mysql-server
sudo systemctl start mysqld

2. 数据库设置：

停止服务：sudo systemctl stop mysqld
修改配置：sudo vi /etc/my.cnfTo prevent deadlocks, set the isolation level to READ-COMMITTED.Configure the InnoDB engine
设置自动启动：sudo systemctl enable mysqld
启动服务：sudo systemctl start mysqld
设置启动密码：sudo /usr/bin/mysql_secure_installation

3. 安装JDBC驱动（所有节点）：

wget https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.46.tar.gz
tar zxvf mysql-connector-java-5.1.46.tar.gz
sudo mkdir -p /usr/share/java/
cd mysql-connector-java-5.1.46
sudo cp mysql-connector-java-5.1.46-bin.jar /usr/share/java/mysql-connector-java.jar

4、根据下表组件中的信息运行如下语句为组件创建用户

CREATE DATABASE <database> DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
GRANT ALL ON <database>.* TO '<user>'@'%' IDENTIFIED BY '<password>’;

初始化数据库sql

CREATE DATABASE  scm CHARACTER SET utf8  COLLATE utf8_general_ci;	
GRANT ALL ON scm.* TO 'scm'@'%' IDENTIFIED BY 'scm';CREATE DATABASE  amon CHARACTER SET utf8  COLLATE utf8_general_ci;	
GRANT ALL ON amon.* TO 'amon'@'%' IDENTIFIED BY 'amon';CREATE DATABASE  rman CHARACTER SET utf8  COLLATE utf8_general_ci;	
GRANT ALL ON rman.* TO 'rman'@'%' IDENTIFIED BY 'rman';CREATE DATABASE  hue CHARACTER SET utf8  COLLATE utf8_general_ci;	
GRANT ALL ON hue.* TO 'hue'@'%' IDENTIFIED BY 'hue';CREATE DATABASE  metastore CHARACTER SET utf8  COLLATE utf8_general_ci;	
GRANT ALL ON metastore.* TO 'hive'@'%' IDENTIFIED BY 'hive';CREATE DATABASE  sentry CHARACTER SET utf8  COLLATE utf8_general_ci;	
RANT ALL ON sentry.* TO 'sentry'@'%' IDENTIFIED BY 'sentry';CREATE DATABASE  nav CHARACTER SET utf8  COLLATE utf8_general_ci;	
GRANT ALL ON nav.* TO 'nav'@'%' IDENTIFIED BY 'nav';CREATE DATABASE  navms CHARACTER SET utf8  COLLATE utf8_general_ci;	
GRANT ALL ON navms.* TO 'navms'@'%' IDENTIFIED BY 'navms';CREATE DATABASE  oozie CHARACTER SET utf8  COLLATE utf8_general_ci;	
GRANT ALL ON oozie.* TO 'oozie'@'%' IDENTIFIED BY 'oozie';

5、运行如下脚本配置scm server数据库：

sudo /opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm scm

Step14: 安装CDH（只在master节点）

1.启动scm server：

sudo systemctl start cloudera-scm-server

2. 查看日志，检查是否启动完成：

sudo tail -f /var/log/cloudera-scm-server/cloudera-scm-server.log
--查看到【WebServerImpl:com.cloudera.server.cmf.WebServerImpl: Started Jetty server.】日志表示启动完成

3. 登录主页(账号/密码：admin/admin)：

http://master:7180

4. 初始化CDH，建立Cluster

CDH启动与关闭

CM Portal 地址：

http://master:7180/cmf/home

关闭步骤：

在CM portal上关闭 cluster
在所有节点关闭CM agent： sudo systemctl stop cloudera-scm-agent
在master节点关闭CM server： sudo systemctl stop cloudera-scm-server

启动步骤：

在所有节点启动CM agent： sudo systemctl start cloudera-scm-agent
在master节点启动CM server： sudo systemctl start cloudera-scm-server
在CM portal上启动 cluster

查看启动日志：

/var/log/cloudera-scm-server/cloudera-scm-server.log
