【Centos7.6安裝CDH6.1.0】手把手教你搭建CDH6.1.0
JDK(已安裝者跳過)
下載linux適用版jdk
https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
下載後分發至mini1、mini2、mini3,解壓,配置環境變量至/etc/profile,這裏貼一下博主的profile相關內容:
export JAVA_HOME=/home/hadoop/apps/jdk1.8.0_191
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
環境變量配置完成後,執行:
[root@mini2 ~]# source /etc/profile
驗證:
[root@mini2 ~]# java -version
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)
mysql配置
root用戶下,在mini1上依次執行如下命令(:
yum remove mysql
wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
yum localinstall mysql57-community-release-el7-8.noarch.rpm
yum install mysql-community-server
yum install mysql-devel
systemctl start mysqld
systemctl enable mysqld
等待安裝完成後,尋找初始密碼:
[root@mini1 mysql]# cat /var/log/mysqld.log | grep "temporary password"
2020-01-31T18:48:39.318109Z 1 [Note] A temporary password is generated for root@localhost: 9.Hkdd:t??2m
使用初始密碼登錄:
[root@mini1 mysql]# mysql -uroot -p9.Hkdd:t??2m
mysql: [Warning] Using a password on the command line interface can be insecure.

修改mysql root登錄密碼:
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '1QAZ@wsx';
注意,新密碼設置要求包含大寫字母、小寫字母及特殊符號(如~!@#)。
安裝jdbc
root用戶下,在mini1上執行命令:
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
mkdir -p /usr/share/java/
cd mysql-connector-java-5.1.46
cp mysql-connector-java-5.1.46-bin.jar /usr/share/java/mysql-connector-java.jar
建庫、建用戶、設置用戶訪問權限
root用戶下,創建腳本mysql_init.sh:
#!/bin/bash
