1
安装mysql
server (only one host)
sudo yum install mysql-server
2
停止mysql
server的运行 (only

sudo service mysqld stop
3
配置mysql

vim
/etc/my.cnf
内容如下：
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
port=3300
transaction-isolation=READ-COMMITTED
max_connections=550
#
Disabling symbolic-links is recommended to prevent assorted security
risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
#InnoDB
settings
innodb_file_per_table
= 1
innodb_flush_log_at_trx_commit
= 2
innodb_log_buffer_size
= 64M
innodb_buffer_pool_size
= 4G
innodb_thread_concurrency
= 8
innodb_flush_method
= O_DIRECT
innodb_log_file_size
= 512M
4
确保mysql服务在服务器开机启动时，就会被启动
(only
one host)
sudo
/sbin/chkconfig mysqld on
sudo
/sbin/chkconfig --list mysqld
5 启动mysql服务 (only one host)
sudo service mysqld start

All done!
7 安装mysql JDBC Connector
在CM服务的主机以及activity monitor,reports manager,cloudera navigator以及Hive Metastore server对应的主机上安装mysql JDBC Connector
sudo yum install mysql-connector-java
8 为hive metastore创建数据库
Log into MySQL as the root user:
$mysql -u root -p
Enter password:
mysql>create database metastore DEFAULT CHARACTER SET utf8;
Query OK, 1 row affected (0.00 sec)
mysql> grant all on metastore.* TO ‘hive‘@‘%‘ IDENTIFIED BY ‘password‘;
Query OK, 0 rows affected (0.00 sec)
9 使用CM安装hive
