Posted 2020-07-08

配置  CDH 本地 YUM
1. 解压介质到本地

[[email protected] CDH]# tar zxvf cm5.2.0-centos6.tar.gz

2. 创建软连接

[[email protected] CDH]# mv cm /opt/

[[email protected] opt]# ln -s /opt/cm /var/www/html/cm_yum

3. 验证

启动 http 服务

[[email protected] yum.repos.d]# service httpd start

[[email protected] yum.repos.d]# chkconfig httpd on

[[email protected] yum.repos.d]# chkconfig | grep httpd
httpd 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭

http://192.168.109.10/cm_yum/能访问即可
4. 创建 repo 文件，索引文件

[[email protected] yum.repos.d]# createrepo  -v /opt/cm/

[[email protected] opt]# cd /etc/yum.repos.d/

vim CDH5.2repo

[cloudera-cdh5]
name=cloudera-cdh5.2
baseurl=http://192.168.109.10/cm_yum/5.2.0/
gpgcheck=0
enable=1

配置 java  环境

1.卸载系统自带OPENJDK

[[email protected] 5.2.0]# rpm -qa|grep openjdk

java-1.6.0-openjdk-devel-1.6.0.35-1.13.7.1.el6_6.x86_64
java-1.7.0-openjdk-devel-1.7.0.79-2.5.5.4.el6.x86_64
java-1.7.0-openjdk-1.7.0.79-2.5.5.4.el6.x86_64
java-1.6.0-openjdk-1.6.0.35-1.13.7.1.el6_6.x86_64
java-1.6.0-openjdk-javadoc-1.6.0.35-1.13.7.1.el6_6.x86_64

[[email protected] 5.2.0]# rpm -e --nodeps java-1.6.0-openjdk-devel-1.6.0.35-1.13.7.1.el6_6.x86_64
[[email protected] 5.2.0]# rpm -e --nodeps java-1.7.0-openjdk-devel-1.7.0.79-2.5.5.4.el6.x86_64
[[email protected] 5.2.0]# rpm -e --nodeps java-1.7.0-openjdk-1.7.0.79-2.5.5.4.el6.x86_64
[[email protected] 5.2.0]# rpm -e --nodeps java-1.6.0-openjdk-javadoc-1.6.0.35-1.13.7.1.el6_6.x86_64
[[email protected] 5.2.0]# rpm -qa|grep openjdk
java-1.6.0-openjdk-1.6.0.35-1.13.7.1.el6_6.x86_64
[[email protected] 5.2.0]# rpm -e --nodeps java-1.6.0-openjdk-1.6.0.35-1.13.7.1.el6_6.x86_64
[[email protected] 5.2.0]# rpm -qa|grep openjdk
[[email protected] 5.2.0]#

2.安装jdk

[[email protected] CDH]# rpm -ivh jdk-7u67-linux-x64.rpm

localedata.jar...
jfxrt.jar...
[[email protected] CDH]#

3.配置环境变量

[[email protected] ~]# vim /etc/profile

###############################
## java
##
###############################
JAVA_HOME=/usr/java/jdk1.7.0_67
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/lib/jt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME PATH CLASSPATH

4.使环境变量配置生效，查看java版本

[[email protected] ~]# source /etc/profile
[[email protected] ~]# java -version
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)
[[email protected] ~]#

配置主机信息

1.配置主机名

[[email protected] ~]# vim /etc/sysconfig/network

NETWORKING=yes
HOSTNAME=master

2.配置hosts

[[email protected] ~]# vim /etc/hosts

192.168.109.10 master
192.168.109.11 slave1
192.168.109.12 slave2

[[email protected] ~]# service network restart

配置SSH互信

生成公匙文件
ssh-keygen -t rsa（所有节点）
整合公匙文件（master）
ssh master cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
ssh slave1 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
ssh slave2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
分发整合后的公匙文件到各个节点（master）
scp ~/.ssh/authorized_keys slave1:~/.ssh/
scp ~/.ssh/authorized_keys slave2:~/.ssh/
测试互信（所有节点）不需要输入密码即配置成功
ssh master
ssh slave1
ssh slave2
