centos7 快速配置手册5 描述如何配置ogg for BigData 增量数据的同步从oracle 到 hdfs


### 基本环境
Virtual Box 下，先配置一台虚拟机 node1 ，配置完hadoop之后，克隆出node2 node3 
最后在node1上配置hive


10.3.105.41 node1 # master  hive
10.3.105.42 node2 # slave1
10.3.105.43 node3 # slave2


### 需要软件
jdk-8u131-linux-x64.tar.gz
hadoop-2.6.0.tar.gz
apache-hive-2.3.0-bin.tar.gz
mysql-connector-java-5.1.42.tar.gz


### 主机部分
timedatectl set-timezone Asia/Shanghai
hostnamectl set-hostname node1
ip a
ip l
ip route
cd /etc/sysconfig/network-scripts/
vi ifcfg-enp0s3
systemctl restart network
vi /etc/hosts
ssh node1 date
setenforce 0
vi /etc/selinux/config 
systemctl stop firewalld
systemctl disable firewalld
systemctl status firewalld




### yum 部分
cd /etc/yum.repos.d/
mkdir bak
mv *.repo bak/
vi dvd.repo
    [dvd]
    name=dvd
    baseurl=file:///mnt/dvd
    gpgcheck=0
mkdir /mnt/dvd
mount -o loop /dev/cdrom /mnt/dvd
yum install -y yum-utils
yum install -y net-tools unzip


### mysql 部分
yum list  mysql-connector-java*
yum list  maria*


repoquery -l mariadb               ### /usr/bin/mysql
repoquery -l mariadb-server        ### /usr/bin/mysqld_safe /etc/my.cnf.d/server.cnf /usr/lib/systemd/system/mariadb.service


yum install -y mariadb mariadb-server mysql-connector-java


systemctl enable mariadb
systemctl start mariadb
systemctl status mariadb -l
more /var/log/mariadb/mariadb.log
mysql
    show databases;
    use mysql
    select host,user,password from user;
    GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'rootroot' WITH GRANT OPTION;
    -- GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.100.%' IDENTIFIED BY 'my-new-password' WITH GRANT OPTION;
    set password for 'root'@'localhost' = password('rootroot') 


-- if enable firewall
firewall-cmd --add-port=3306/tcp 
firewall-cmd --permanent --add-port=3306/tcp
