1 安装mysql server (only one host)

sudo yum install mysql-server

2 停止mysql server的运行 (only one host)

sudo service mysqld stop

3 配置mysql server (only one host)

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

6 设置mysql
root的密码 (only one host)

如下：红色文字为需要输入的。

sudo /usr/bin/mysql_secure_installation

[...]

Enter current password for root (enter for none):

OK,

All done!

7 安装mysql JDBC Connector

monitor,reports manager,cloudera navigator以及Hive
Metastore server对应的主机上安装mysql
JDBC Connector

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)
