安装CM

  • 将下载好的cloudera-manager-centos7-cm5.13.0_x86_64.tar.gz解压到主节点的/opt/,解压出来的文件夹为cloudera与cm-5.13.0

  • 为Cloudera Manager建立数据库，此处需要前边下载好的mysql-connector-java-5.1.47-bin.jar

    • cp /root/software/mysql-connector-java-5.1.47/mysql-connector-java-5.1.47-bin.jar /usr/java/
    • cp /root/software/mysql-connector-java-5.1.47/mysql-connector-java-5.1.47-bin.jar /opt/cm-5.13.0/share/cmf/lib/

    主节点执行 执行前确认用户创建无问题(用户创建可能遇到密码策略不符合)

    初始化数据库根据数据库的位置不同而不同：下面为数据库与cm 在统一主机

    /opt/cm-5.13.0/share/cmf/schema/scm_prepare_database.sh mysql -uroot -p123 scm scm scm

配置Agent（统一复制到其他节点，省的重新做了）

vim /opt/cm-5.13.0/etc/cloudera-scm-agent/config.ini
server_host=cdh01

拷贝文件到其他子节点

scp -r /opt/cm-5.13.0/ root@hywx189:/opt/
scp -r /opt/cm-5.13.0/ root@hywx189:/opt/

所有节点上创建用户　 注意家目录的不同/opt/cm-5.13.0/run/cloudera-scm-server/

初始化前将java-mysql 驱动安装到每个节点的给定位置：（见下文测试数据库）

useradd --system --home=/opt/cm-5.13.0/run/cloudera-scm-server --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm

useradd --system --home=/opt/cm-5.13.3/run/cloudera-scm-server --no-create-home --shell=/bin/false --comment "Cloudera SCM User" cloudera-scm

配置存储目录（主节点貌似）

$ sudo mkdir /var/lib/cloudera-scm-server
$ sudo chown cloudera-scm:cloudera-scm /var/lib/cloudera-scm-server

准备parcels，将CDH相关文件拷贝到主节点/opt/cloudera/parcel-repo/*

注：需要将CDH-5.13.0-1.cdh5.13.0.p0.29-el7.parcel.sha1改成CDH-5.13.0-1.cdh5.13.0.p0.29-el7.parcel.sha，否则安装时会重新下载，很重要！！

mv CDH-5.13.0-1.cdh5.13.0.p0.29-el7.parcel.sha1 CDH-5.13.0-1.cdh5.13.0.p0.29-el7.parcel.sha

启动

##主节点
/opt/cm-5.13.0/etc/init.d/cloudera-scm-server start

#主节点及其他节点
/opt/cm-5.13.0/etc/init.d/cloudera-scm-agent start

启动需要点时间，可以查看数据库scm中的hosts表，如果里面出现节点信息表示server启动完成

启动成功查看方式：

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

安装Hadoop集群

  • 启动成功后 浏览器访问：
    • http://主节点ip:7180 （用户名、密码：admin）

  • 第一个警告直接在所有节点上执行

    • echo 10 > /proc/sys/vm/swappiness

  • 第二个警告按照上面的说明，在所有节点上执行这两条命令

    • echo never >/sys/kernel/mm/transparent_hugepage/defrag >> /etc/rc.local
    • echo never > /sys/kernel/mm/transparent_hugepage/enabled>> /etc/rc.local
    • 同时同一命令添加到 /etc/rc.local 等初始化脚本中，以便在系统重启时予以设置。

    测试数据库时

此处hive ，oozie会安装失败，失败信息如下。因为我们使用了MySQL作为hive元数据存储，需要将mysql驱动拷贝到hive和oozie目录下

解决方法（需要在所有节点上执行）

  • cp /opt/cm-5.13.0/share/cmf/lib/mysql-connector-java-5.1.47-bin.jar /opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/lib/hive/lib/
  • cp /opt/cm-5.13.0/share/cmf/lib/mysql-connector-java-5.1.47-bin.jar /var/lib/oozie/

cp /opt/cm-5.7.1/share/cmf/lib/mysql-connector-java-*-bin.jar /opt/cloudera/parcels/CDH-5.7.1-1.cdh5.7.1.p0.11/lib/hive/lib/

cp /opt/cm-5.7.1/share/cmf/lib/mysql-connector-java-*-bin.jar /opt/cloudera/parcels/CDH-5.7.1-1.cdh5.7.1.p0.11/lib/oozie/lib/

cp /opt/cm-5.7.1/share/cmf/lib/mysql-connector-java-*-bin.jar /var/lib/oozie/

初始化  yum安装的scm_prepare_database.sh 位置
 cd    /usr/share/cmf/lib/
 mv   /usr/share/java/mysql-connector-java-5.1.46-bin.jar  .
 
 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  .
 
 
 安装MySQL JDBC驱动程序
从下载的文件中提取JDBC驱动程序JAR文件。例如：
tar zxvf mysql-connector-java-5.1.46.tar.gz
将重命名的JDBC驱动程序复制到 /usr/share/java/。如果目标目录尚不存在，请创建它。例如：
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  
sudo cp mysql-connector-java-5.1.46-bin.jar /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

另外如果想添加新的主机，必须要先启动新主机上的agent服务，否则新主机不能被发现，要重新下载cm-agent，很麻烦。安装新的节点以后，记得运行"部署客户端"命令。

yum安装cm

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 ; 
ALTER USER 'root'@'localhost' IDENTIFIED BY '[email protected]';
FLUSH PRIVILEGES;


mysql -uroot [email protected]

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('[email protected]');

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 '[email protected]' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'cdh'@'%' IDENTIFIED BY '[email protected]' 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 '[email protected]' with grant option;

create database hive default character set utf8  DEFAULT COLLATE utf8_general_ci;

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   [email protected]   --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
