三、jdk安装（每台机器）
tar zxvf jdk-8u111-linux-x64.gz
mv jdk1.8.0_111 /usr/local/jdk
配置环境变量

##mysql
export MYSQL_HOME=/data/app/mysql5.6
export MY_BASEDIR_VERSION=/data/app/mysql5.6
export PATH=/data/app/mysql5.6/bin:$PATH
export LD_LIBRARY_PATH=/data/app/mysql5.6/lib
环境生效
source /etc/profile
5.8、初始化数据库
/data/app/mysql5.6/scripts/mysql_install_db --user=mysql --basedir=/data/app/mysql5.6 --datadir=/data/app/mysql3306
5.9、配置启动文件
cp /data/app/mysql5.6/support-files/mysql.server /etc/init.d/mysqld
vi /etc/init.d/mysqld
basedir=/data/app/mysql5.6
datadir=/data/app/mysql3306
保存退出
chmod +x /etc/init.d/mysqld
chkconfig mysqld on
启动
/etc/init.d/mysqld start
5.10、初始化密码
/data/app/mysql5.6/bin/mysqladmin -u root password 'yb2018#08'
5.11、设置远程权限
# mysql -uroot -pyb2018#08
Warning: Using a password on the command line interface can be insecure.

六、安装Cloudera-Manager
6.1、解压包到指定目录，所有服务器都要
mkdir -p /data/cloudera-manager
tar zxvf cloudera-manager-el6-cm5.13.3_x86_64.tar.gz -C /data/cloudera-manager
6.2创建cloudera-scm用户(所有节点)
useradd -r -d /data/cloudera-manager/cm-5.13.3/run/cloudera-scm-server -M -c"Cloudera SCM User" cloudera-scm
id cloudera-scm
6.3、配置从节点cloudera-manger-agent指向主节点服务器（hadoop02,hadoop03配置）
vi /data/cloudera-manager/cm-5.13.3/etc/cloudera-scm-agent/config.ini
将server_host改为CMS所在的主机名即hadoop01
6.4、主节点中创建parcel-repo仓库目录（这个只在主节点hadoop01上需要）
mkdir -p /data/cloudera/parcel-repo
chown cloudera-scm:cloudera-scm /data/cloudera/parcel-repo
cp CDH-5.13.3-1.cdh6.13.3.p0.2-el6.parcel CDH-5.13.3-1.cdh6.13.3.p0.2-el6.parcel.sha1 manifest.json /data/cloudera/parcel-repo/
cd /data/cloudera/parcel-repo/
mv CDH-5.13.3-1.cdh6.13.3.p0.2-el6.parcel.sha1 CDH-5.13.3-1.cdh6.13.3.p0.2-el6.parcel.sha
注意：其中CDH-5.13.3-1.cdh6.13.3.p0.2-el6.parcel.sha1 后缀要把1去掉
6.5、所有节点创建parcels目录（所有节点）
mkdir -p /data/cloudera/parcels
chown cloudera-scm:cloudera-scm /data/cloudera/parcels
解释：Clouder-Manager将CDHs从主节点的/data/cloudera/parcel-repo目录中抽取出来，分发解压激活到各个节点的/data/cloudera/parcels目录中
6.6、初始脚本配置数据库scm_prepare_database.sh(在主节点上)
/data/cloudera-manager/cm-5.13.3/share/cmf/schema/scm_prepare_database.sh mysql -uscm -ptemp scm scm temp
如果报错，操作
mkdir /usr/share/java
cp mysql-connector-java-5.1.46-bin.jar /usr/share/java/mysql-connector-java.jar
上图说明成功
成功把记住把#127.0.0.1 localhost hadoop01 注释掉，不然后面就会有问题
vi /etc/hosts
#127.0.0.1 hadoop01
192.168.1.201 hadoop01
192.168.1.202 hadoop02
192.168.1.203 hadoop03
6.7、启动主节点cloudera-scm-server(hadoop01操作)
cp /data/cloudera-manager/cm-5.13.3/etc/init.d/cloudera-scm-server /etc/init.d/cloudera-scm-server
chmod +x /etc/init.d/cloudera-scm-server
启动
/etc/init.d/cloudera-scm-server start
如果报File not found: /usr/sbin/cmf-server错误
vi /etc/init.d/cloudera-scm-server
找到CMF_DEFAULTS=${CMF_DEFAULTS:-/etc/default}
修改成CMF_DEFAULTS=/data/cloudera-manager/cm-5.13.3/etc/default
启动
/etc/init.d/cloudera-scm-server start
6.8、启动cloudera-scm-agent所有节点(hadoop02,hadoop03操作)
mkdir /data/cloudera-manager/cm-5.13.3/run/cloudera-scm-agent
cp /data/cloudera-manager/cm-5.13.3/etc/init.d/cloudera-scm-agent /etc/init.d/cloudera-scm-agent
chmod +x /etc/init.d/cloudera-scm-agent
/etc/init.d/cloudera-scm-agent start
vi /etc/init.d/cloudera-scm-agent
找到CMF_DEFAULTS=${CMF_DEFAULTS:-/etc/default}
修改成CMF_DEFAULTS=/data/cloudera-manager/cm-5.13.3/etc/default
启动
/etc/init.d/cloudera-scm-agent start
6.9、登录用户admin 密码admin
http://192.168.1.201:7180
继续
选择免费，继续
继续
选择当前管理主机选择hadoop02,hadoop03,继续
点击更多选项配置
修改好后，保存修改
重启后才后出下如下图
/etc/init.d/cloudera-scm-server restart
重启好后才能如上图继续，因为默认/opt下安装的
继续
每台执行以下
echo 10 >/proc/sys/vm/swappiness
echo never >/sys/kernel/mm/transparent_hugepage/defrag
echo never >/sys/kernel/mm/transparent_hugepage/enabled
以图根据自己需求选择不一样点继续
以上Datanode修改两台
把连接主机名，数据库名称，用户名，密码输入进去，点击测试连接都Succesful成功后，点击继续
根据自己修改点击继续
继续
安装完成
