1、由于hive的元数据存储在关系型数据库中，先安装mysql

mysql官网，选择社区版：https://dev.mysql.com/downloads/mysql/5.7.html#downloads

wget下载安装包：wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz

解压：tar -zxvf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz

创建data文件：mkdir data #路径为/usr/local/src/mysql/data

需要创建mysql用户和用户组：

groupadd mysql

useradd -r -g mysql mysql

将安装文件和data文件修改为mysql用户：

chown -R mysql:mysql /usr/local/src/mysql

chmod -R 777 data /usr/local/src/mysql/data

修改配置：

./mysql_ssl_rsa_setup --datadir=/usr/local/src/mysql/data

vi /etc/my.cnf 修改为：(修改datadir的存储位置)

basedir=/usr/local/src/mysql/mysql

datadir=/usr/local/src/mysql/data

port = 3306

socket=/tmp/mysql.sock

pid-file=/tmp/mysqld/mysqld.pid

character-set-server = utf8

log-error=/var/log/mysqld.log

创建/tmp/mysql.sock、/tmp/mysqld/mysqld.pid、/var/log/mysqld.log，并分别修改mysql用户权限：

cd /tmp

touch mysql.sock

chown mysql:mysql mysql.sock

chmod 755 mysql.sock

cd /tmp/mysqld/

touch mysqld.pid

chown -R mysql:mysql mysqld.pid

chmod 755 mysqld.pid

cd /var/log/

touch mysqld.log

chown -R mysql:mysql /var/log

chmod 755 mysqld.log

修改环境变量：vi ~/.bash_profile

修改为：PATH=$PATH:$HOME/bin:/usr/local/src/mysql/mysql/bin

然后source ~/.bash_profile

初始化：./mysqld --initialize --user=root --basedir=/usr/local/src/mysql/mysql --datadir=/usr/local/src/mysql/data --lc_messages_dir=/usr/local/src/mysql/mysql/share --lc_messages=en_US

进入mysql的bin目录下，./mysqld_safe --user=mysql启动mysql，在/var/log/mysqld.log中找生成的临时密码：

然后mysql -uroot -p输入临时密码，即进入mysql命令终端；

设置密码，安装完成：

use mysql

update user set host=‘%‘ where user=‘root‘;

GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘......‘ WITH GRANT OPTION;（或者是：grant all privileges on *.* to root@‘%‘ identified by "新密码";）

FLUSH PRIVILEGES;

设置开机自动启动：

cp /usr/local/src/mysql/mysql/support-files/mysql.server /etc/init.d/mysql

chkconfig --list mysql

service mysql start

service mysql stop

2、安装hive

获取bin安装包：wget http://mirror.bit.edu.cn/apache/hive/hive-3.1.1/apache-hive-3.1.1-bin.tar.gz

tar -zxvf apache-hive-3.1.1-bin.tar.gz

ln -s apache-hive-3.1.1-bin hive

修改环境变量：/etc/profile，添加

#hive

export HIVE_HOME=/usr/local/src/hive/hive

export PATH=$PATH:$HIVE_HOME/bin

然后： source /etc/profile

hive --version

进入conf目录，进行设置：cd /usr/local/src/hive/hive/conf

cp hive-default.xml.template hive-site.xml

vi hive-site.xml，增加：

<name>javax.jdo.option.ConnectionURL</name>

<value>jdbc:mysql://localhost:3306/hive</value>

</property>

<name>javax.jdo.option.ConnectionDriverName</name>

<value>com.mysql.jdbc.Driver</value>

</property>

<name>javax.jdo.option.ConnectionUserName</name>

</property>

<name>javax.jdo.option.ConnectionPassword</name>

</property>

<name>hive.metastore.schema.verification</name>

<value>false</value>

</property>

</configuration>

进入mysql数据库，创建hive数据：

create database hive;

进入lib目录，cd ../lib，下载mysql的连接包：

wget http://central.maven.org/maven2/mysql/mysql-connector-java/5.1.47/mysql-connector-java-5.1.47.jar

进入hive安装目录bin目录下：执行schematool -dbType mysql -initSchema

初始化成功：

[root@master bin]# schematool -dbType mysql -initSchema

hive自动创建的表：

........

由于已经新建了环境变量，直接输入hive进入命令终端：

出现了大量的warn信息，是由于 MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn‘t set，在hive的hive-site.conf中加上useSSL=false，即不启用SSL连接就可以：
