You will find that password in '/root/.mysql_secret'. You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag. Also, the account for the anonymous user has been removed. In addition, you can run: /usr/bin/mysql_secure_installation which will also give you the option of removing the test database.
This is strongly recommended for production servers. See the manual for more instructions. Please report any problems at http://bugs.mysql.com/ The latest information about MySQL is available on the web at http://www.mysql.com Support MySQL by buying support/licenses at http://shop.mysql.com New default config file was created as /usr/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings [root@ip---- mysql]#
mysql5.6对为root用户生产了一个随机密码,这个随机密码存放在/root/.mysql_secret中
[root@ip---- mysql]# cat /root/.mysql_secret
# The random password set for the root user at Tue Dec :: (local time): 6yoMKdmnzyIfvZA3
[root@ip---- mysql]# mysql -u root -p
Enter password:

affiliates. Other names may be trademarks of their respective
owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
所以要登录到mysql并修改掉这个随机生产的密码,上面的提示符后面应该输入/root/.mysql_secret中的随机密码,登录后,用SET PASSWORD修改密码：
mysql> SET PASSWORD = PASSWORD('');
Query OK, rows affected (0.00 sec)
mysql>
注意命令的大小写！
2.设置开机启动mysql并启动服务：
[root@ip---- mysql]# chkconfig mysql on
[root@ip---- mysql]# service mysql start
Starting MySQL. SUCCESS!
[root@ip---- mysql]#
3.安装MySQL JDBC Driver
在需要访问MySQL的机器上(比如CMS,MGMT角色)安装jdbc driver
[root@ip---- mysql]# unzip mysql-connector-java-5.1..zip
[root@ip---- mysql]# cp mysql-connector-java-5.1./mysql-connector-java-5.1.-bin.jar /usr/share/java
[root@ip-172-31-30-175 java]# ln -s mysql-connector-java-5.1.37-bin.jar mysql-connector-java.jar

3.为Cloudera管理器配置外部数据库
为了保证在生产环境的安全，禁止远程机器以root用户登录，禁止匿名登录。这步在POC环境下可选。注意root的密码为上一步中设置的123456
[root@ip---- ec2-user]# /usr/bin/mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here. Enter current password for root (enter for none):
OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation. You already have a root password set, so you can safely answer 'n'. Change the root password? [Y/n] n
... skipping. By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment. Remove anonymous users? [Y/n] Y
... Success! Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] n
... skipping. By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment. Remove test database and access to it? [Y/n] Y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success! Reloading the privilege tables will ensure that all changes made so far
will take effect immediately. Reload privilege tables now? [Y/n] Y
... Success! All done! If you've completed all of the above steps, your MySQL
installation should now be secure. Thanks for using MySQL! Cleaning up...
