安全初始化MySQL服务器
安全初始化MySQL服务器
在安装完MySql服务器,设置好MySql的root用户密码后,就直接开始使用了,其实这样的MySql服务器还存在着一些不安全因素,本篇演示一下用命令mysql_secure_installation来安全初始化我们的MySql服务器。
第一步,安装,启动MySql服务器,并添加到开机自动启动:
[root@
test
~]
# \cp -f /usr/share/mysql/my-medium.cnf /etc/my.cnf
*
/etc/my
.cnf的详细设定等,不在本篇讨论范围,读者根据你自己的需求设置,在这里直接用了自带的my-medium.cnf。
[root@
test
~]
# /etc/init.d/mysqld start
[root@
test
~]
# chkconfig mysqld on
第二步,用mysql_secure_installation安全初始化MySql服务器:
[root@
test
~]
# /usr/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):<---输入现在的root密码,因为我们还没设置,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 <---是否设定root密码,当然设置了,输入Y回车
New password: <---输入root密码,并回车,输入的过程中不会有任何显示
Re-enter new password: <---再次输入root密码,并回车,输入的过程中不会有任何显示
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 <---是否删除匿名用户,删除,输入Y回车
... 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
] Y <---是否删禁止root用户远程登录,当然禁止,输入Y回车
... 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
] <---是否删除测试数据库
test
,删除,输入Y回车
- 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 <---刷新权限,输入Y回车
... 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!
后话:我们都知道,安全只是相对的,所以并不是说有了上面的安全初始化,我们的MySql服务器就绝对安全了。
