安裝完mysql-server 會提示可以運行mysql_secure_installation。運行mysql_secure_installation會執行幾個設定：
a)為root使用者佈建密碼
b)刪除匿名帳號
c)取消root使用者遠程登入
d)刪除test庫和對test庫的存取權限
e)重新整理授權表使修改生效
通過這幾項的設定能夠提高mysql庫的安全。建議生產環境中mysql安裝這完成後一定要運行一次mysql_secure_installation，詳細步驟請參看下面的命令:
複製代碼代碼如下:
[[email protected] ~]# 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):<–初次運行直接斷行符號
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] <– 是否設定root使用者密碼，輸入y並斷行符號或直接斷行符號
New password: <– 設定root使用者的密碼
Re-enter new password: <– 再輸入一次你設定的密碼
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] <– 是否刪除匿名使用者,生產環境建議刪除，所以直接斷行符號
… 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] <–是否禁止root遠程登入,根據自己的需求選擇Y/n並斷行符號,建議禁止
… 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] <– 是否刪除test資料庫,直接斷行符號
- 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] <– 是否重新載入許可權表，直接斷行符號
… 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!
