[root@iZ2zeibok6t3svl00dy8jyZ ~]# chkconfig mysqld on

</font>

## 三、数据库安全
### 1.启动服务
<font size=4>

[root@iZ2zeibok6t3svl00dy8jyZ ~]# service mysqld restart
Shutting down MySQL.. SUCCESS!
Starting MySQL. SUCCESS!
[root@iZ2zeibok6t3svl00dy8jyZ ~]#

</font>
### 2.安全设置
<font size=4>

[root@iZ2zeibok6t3svl00dy8jyZ ~]#/data/mysql/soft/bin/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): # 输入当前 root 密码，如果没有直接回车
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] Y # 是否设置 root 密码
New password: # 输入 root 密码
Re-enter new password: # 再次确定 root 密码
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] Y # 清除匿名用户
... 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] n # 是否禁止 root 远程登录
... skipping.

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] Y # 是否清除 test 数据库

• 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] Y # 是否重新加载权限
... Success!

All done! If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!

Cleaning up...
