cdh6.2.1搭建安装

1、为CM安装mysql驱动

4台服务器

将mysql-connector-java-5.1.27-bin.jar拷贝到/usr/share/java路径下，并重命名

mv mysql-connector-java-5.1.27-bin.jar mysql-connector-java.jar

2、CM安装

yct40安装：cloudera-scm-server,cloudera-scm-agent

yct41 安装：cloudera-scm-agent

yct42 安装：cloudera-scm-agent

yct43 安装：cloudera-scm-agent

搭建本地yum源

将压缩包cloudera-repos.tar.gz拷贝到yct40中的一台节点，/home/download

解压到/var/www/html路径下

tar -zxvf cloudera-repos.tar.gz -C /var/www/html

cd /var/www/html/

python -m SimpleHTTPServer 8900

浏览器访问http://192.168.10.40:8900

vim /etc/yum.repos.d/cloudera-manager.repo

输入：
[cloudera-manager]

name=cloudera-manager

baseurl=http://yct40:8900/cloudera-repos/cm6/6.2.1/redhat7/yum/

enabled=1

gpgcheck=0

分发

xsync /etc/yum.repos.d/cloudera-manager.repo

yct40:

yum -y install cloudera-manager-daemons cloudera-manager-agent cloudera-manager-server

yct41:

yum -y install cloudera-manager-agent cloudera-manager-daemons

yct42:

yum -y install cloudera-manager-agent cloudera-manager-daemons

yct43:
yum -y install cloudera-manager-agent cloudera-manager-daemons

修改yct40上CM的配置文件（不用xsync同步）

vim /etc/cloudera-scm-agent/config.ini

server_host=yct40

server_port=7182

3、在mysql中建库

CREATE DATABASE scm DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;

CREATE DATABASE amon DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;

CREATE DATABASE hue DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;

CREATE DATABASE hive DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;

CREATE DATABASE sentry DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;

CREATE DATABASE oozie DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;

为CM配置数据库（cm自带脚本）

/opt/cloudera/cm/schema/scm_prepare_database.sh mysql scm root ycT_big@!123!com

4、启动CM服务

yct40:

systemctl start cloudera-scm-server

systemctl start cloudera-scm-agent

yct41:

systemctl start cloudera-scm-agent

yct42:

systemctl start cloudera-scm-agent

yct43:

systemctl start cloudera-scm-agent

yct40上可通过tail查看日志，出现started jetty server即安装成功

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

浏览器访问：http://192.168.10.40:7180

用户名和密码都是admin/admin

5、关闭CM服务

关闭工作节点

43：systemctl stop cloudera-scm-agent

42：systemctl stop cloudera-scm-agent

41：systemctl stop cloudera-scm-agent

40：systemctl stop cloudera-scm-agent

40：systemctl stop cloudera-scm-server

关闭服务节点

40：systemctl stop cloudera-scm-server
