2.開始安裝MySQL5

首先我們應該先用下面的命令安裝MySQL：

yum install mysql mysql-server

然后我們需要創建MySQL系統的啟動鍵鏈接啟動MySQL服務器，這樣以便于MySQL在系統啟動時自動啟動

chkconfig --levels 235 mysqld on

/etc/init.d/mysqld start

為MySQL root帳戶設置密碼：

mysql_secure_installation

會出現下面的一系列提示：

root@server1 ~]# mysql_secure_installation

NOTE： RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL

SERVERS IN PRODUCTION USE！ PLEASE READ EACH STEP CAREFULLY！

In order to log into MySQL to secure it， we'll need the current

password for the root user. If you've just installed MySQL， and

you haven't set the root password yet， the password will be blank，

so you should just press enter here.

Enter current password for root (enter for none)：

OK， successfully used password， moving on...

Setting the root password ensures that nobody can log into the MySQL

root user without the proper authorisation.

Set root password？ [Y/n]

New password：

Re-enter new password：

Password updated successfully！

Reloading privilege tables..

... Success！

By default， a MySQL installation has an anonymous user， allowing anyone

to log into MySQL without having to have a user account created for

them. This is intended only for testing， and to make the installation

go a bit smoother. You should remove them before moving into a

production environment.

Remove anonymous users？ [Y/n]

... Success！

Normally， root should only be allowed to connect from 'localhost'. This

ensures that someone cannot guess at the root password from the network.

Disallow root login remotely？ [Y/n]

... Success！

By default， MySQL comes with a database named 'test' that anyone can

access. This is also intended only for testing， and should be removed

before moving into a production environment.

Remove test database and access to it？ [Y/n]

- Dropping test database...

... Success！

- Removing privileges on test database...

... Success！

Reloading the privilege tables will ensure that all changes made so far

will take effect immediately.

Reload privilege tables now？ [Y/n]

... Success！

Cleaning up...

All done！ If you've completed all of the above steps， your MySQL

installation should now be secure.

Thanks for using MySQL！

[root@server1 ~]#
