PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h hqw.net password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

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.

Please report any problems with the /usr/bin/mysqlbug script!

--copy主配置文件
[root@hqw ~]# cp /usr/share/mysql/my-huge.cnf  /etc/my.cnf

--往主配置文件添加 skip-name-resolve，skip-grant-tables为加快远程连接

--改动mysql的配置文件，在my.cnf中的[mysqld]下面（位置不能错）加上lower_case_table_name=1这句（1表示不区分大小写，0区分大小写），保存重新启动mysql

# Example MySQL config file for very large systems.
#
# This is for a large system with memory of 1G-2G where the system runs mainly
# MySQL.
#
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients

#password       = your_password
