YUM安装MYSQL后,第一次启动时的安全提示

MySQL 5.1.69

[root@localhost init.d]# ./mysqld start
Initializing MySQL database:  Installing MySQL system tables... 
OK 
Filling help tables... 
OK 

To start mysqld at boot time you have to copy 
support-files/mysql.server to the right place for your system 

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 localhost.localdomain 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!
