linux下安装mysql

在启动mysql过程中，出现下面的提示:

 

linux-spru:/home/zhang # /etc/init.d/mysql start

Creating MySQL privilege database...
Installing MySQL system tables...
120310 19:57:26 [Warning] '--skip-locking' is deprecated and will be removed in a future release. Please use '--skip-external-locking' instead.
OK

120310 19:57:28 [Warning] '--skip-locking' is deprecated and will be removed in a future release. Please use '--skip-external-locking' instead.
OK

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 linux-spru.site 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:
rcmysql start

You can test the MySQL daemon with mysql-test package

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