HA分布式集群二hive配置

rpm -qa|grep mariadb
tar -zxvf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz
存在：rpm -e mariadb-libs-5.5.52-1.el7.x86_64 --nodeps

# ha1环境下：mysql版本mysql-5.7.18-linux-glibc2.5-x86_64
cp mysql-5.7.18-linux-glibc2.5-x86_64 /usr/mysql -r
#创建用户组及用户
groupadd mysql
useradd -r -g mysql mysql

cd /usr/local/mysql
mkdir data
chown -R mysql:mysql /usr/mysql 
#验证权限：
ls -trhla
#创建配置文件：
vim /etc/my.conf    #一开始并不存在
basedir=/usr/local/mysql/
datadir/usr/local/mysql/data
scoket=/tmp/mysql.sock
user=mysql
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-fils=/var/run/mysqld/mysqld.pid
#创建文件夹
cd /var/run
mkdir mysqld
cd mysqld
vim mysqld.pid    #什么都不用写，退出
chown -R mysql:mysql /var/run/mysqld

#初始化：
cd /usr/local/mysql/bin
./mysqld --initialize
生成初始密码： gctlsOja8<%0

#添加自启动脚本服务
chown -R mysql:mysql /usr/local/mysql
cp support-files/mysql.server /etc/init.d/mysql
service mysql start
进程查看： ps -ef | grep mysql

#登录
mysql    ./mysql -u root -p    输入密码

#修改密码    
set password=password("123456")；

#客户端远程连接mysql服务器问题：
grant all privileges on *.* to root@‘%‘ identified by ‘1234567‘;
flush privileges;(sql语句记得加分号啊）

#解决root权限访问所有数据库的问题
grant all privileges on *.* to ‘root‘@‘Master‘ identified by ‘123456‘ with grant option;(连接权限的问题）
flush privileges;

#创建hive数据库
create database hive default charset utf8 collate utf8_general_ci;

#设置mysql自启动
cd /etc/init.d
chmod +x mysql
chkconfig --add mysql
chkconfig --list(3到5都为开，则添加成功）

#配置环境变量：
vim /etc/profile 
export MYSQL_HOME=/usr/local/mysql
export PATH=$JAVA_HOME/bin:$MYSQL_HOME/bin:$PATH
source /etc/profile

#验证：    ok
reboot
netstat -na |grep 3306
mysql -u root -p123456

1，启动hadoop    前提先启动zk
cd $ZK_HOME/bin
zkServer.sh start
    在namenode启动start-all.sh
2，可以放在任一台hadoop集群中
3，解压 tar -zxf apache-hive-2.1.1-bin.tar.gz
4，mv apache-hive-2.1.1-bin /usr/hive-2.1.1
mv mysql-connector-java-5.1.42-bin.jar /usr/hive-2.1.1/lib
5，环境变量设置
vim /etc/profie
export HIVE_HOME=/usr/hive-2.1.1
export PATH=$PATH:$HIVE_HOME/bin
export CLASSPATH=$CLASSPATH:$HIVE_HOME/bin
$source /etc/profile

cd /app/soft/hive-2.1.1/conf
cp hive-env.sh.template hive-env.sh
vim hive-env.sh 
export HADOOP_HOME=/usr/hadoop-2.7.3
export HIVE_CONF_DIR=/usr/hive-2.1.1/conf

touch hive-site.xml
vim hive-site.xml
