A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER ! 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.

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
把mysql开机自启关闭 #chkconfig --level 2345 mysql off # chkconfig --list mysql mysql 0:off 1:off 2:off 3:off 4:off 5:off 6:off
三、配置MySQL数据库参数文件my.cnf 编辑 my.cnf文件 #vi /usr/my.cnf # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
[mysqld]

# Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin
# These are commonly set, remove the # and set as required. basedir = /usr datadir = /mysql/data/mysqldata/mydata port = 3306 socket = /mysql/data/mysqldata/sock/mysql.sock tmpdir=/mysql/data/mysqldata/tmpdir
# Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. join_buffer_size = 128M sort_buffer_size = 2M read_rnd_buffer_size = 2M

which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers.
See the manual for more instructions. You can start the MySQL daemon with: cd /usr ; /usr/bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
