------------------------------本案例hive和mysql安装在同一台服务器上-----------------------------------------
1、上传hive、mysql、mysql driver到服务器/mnt目录下：
[root@chavin mnt]# ll mysql-5.6.24-linux-glibc2.5-x86_64.tar.gz apache-hive-0.13.1-bin.tar.gz mysql-connector-java-5.1.22-bin.jar
-rw-r--r--. 1 root root 54246778 Mar 13 10:46 apache-hive-0.13.1-bin.tar.gz
-rw-r--r--. 1 root root 312043744 Mar 13 10:46 mysql-5.6.24-linux-glibc2.5-x86_64.tar.gz
-rw-r--r--. 1 root root 832960 Mar 13 10:46 mysql-connector-java-5.1.22-bin.jar
2、安装mysql数据库：
#tar -zxvf mysql-5.6.24-linux-glibc2.5-x86_64.tar.gz
#mv mysql-5.6.24-linux-glibc2.5-x86_64 /usr/local/mysql-5.6.24
#cd /usr/local/
#chown -R hadoop:hadoop hive-0.13.1/
#cd mysql-5.6.24/
#vim support-files/my-default.cnf
#cp my-default.cnf /etc/my.cnf
#scripts/mysql_install_db --user=mysql
#cp support-files/mysql.server /etc/rc.d/init.d/mysql
#chkconfig --add /etc/rc.d/init.d/mysql
#chkconfig --list mysql
#service mysql status
#service mysql start
#ps -ef|grep mysql
#bin/mysql -uroot
mysql>use mysql;
mysql>set password=password('mysql');
mysql>delete from user where password is null;
3、安装hive
#tar -zxvf apache-hive-0.13.1-bin.tar.gz
#mv apache-hive-0.13.1-bin /usr/local/hive-0.13.1
#cp mysql-connector-java-5.1.22-bin.jar /usr/local/hive-0.13.1/lib/
#cd /usr/local/hive-0.13.1/conf
#vim hive-env.sh
