安装之后，新建用户及密码，新建数据库，分配权限

mysql CREATE USER user@% IDENTIFIED BY password;

Query OK, 0 rows affected (0.00 sec)

mysql create database DB;

Query OK, 1 row affected (0.00 sec)



mysql create database DB default character set utf8 collate utf8_general_ci; (为了DJANGO操作中文不乱码) 

Query OK, 1 row affected (0.00 sec)

mysql GRANT ALL ON DB.* TO user@%; 



Query OK, 0 rows affected (0.00 sec) 



mysql flush privileges; 


Query OK, 0 rows affected (0.00 sec)

YUM安装的MYSQL之后，第一次启动时的安全配置：

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 cnsz141539 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.

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 /usr/mysql-test ; perl mysql-test-run.pl

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

如果要将MYSQL放入SERVICE服务，相应的脚本为：

#!/bin/sh

# mysqld This shell script takes care of starting and stopping

# the MySQL subsystem (mysqld).

# chkconfig: - 64 36
