Asegurar la Instalación
1 [root@Pridd etc]# mysql_secure_installation
2
3 NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
4 SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
5
6 In order to log into MariaDB to secure it, "we'll" need the current
7 password for the root user. If "you've" just installed MariaDB, and
8 you "haven't" set the root password yet, the password will be blank,
9 so you should just press enter here.
10
11 Enter current password for root (enter for none):
12 OK, successfully used password, moving on...
13
14 Setting the root password ensures that nobody can log into the MariaDB
15 root user without the proper authorisation.
16
17 Set root password? [Y/n] y
18 New password:
19 Re-enter new password:
20 Password updated successfully!
21 Reloading privilege tables..
22 ... Success!
23
24
25 By default, a MariaDB installation has an anonymous user, allowing anyone
26 to log into MariaDB without having to have a user account created for
27 them. This is intended only for testing, and to make the installation
28 go a bit smoother. You should remove them before moving into a
29 production environment.
30
31 Remove anonymous users? [Y/n] y
32 ... Success!
33
34 Normally, root should only be allowed to connect from 'localhost'. This
35 ensures that someone cannot guess at the root password from the network.
36
37 Disallow root login remotely? [Y/n] y
38 ... Success!
39
40 By default, MariaDB comes with a database named 'test' that anyone can
41 access. This is also intended only for testing, and should be removed
42 before moving into a production environment.
43
44 Remove test database and access to it? [Y/n] y
45 - Dropping test database...
46 ... Success!
47 - Removing privileges on test database...
48 ... Success!
49
50 Reloading the privilege tables will ensure that all changes made so far
51 will take effect immediately.
52
53 Reload privilege tables now? [Y/n] y
54 ... Success!
55
56 Cleaning up...
57
58 All done! If "you've" completed all of the above steps, your MariaDB
59 installation should now be secure.
60
61 Thanks for using MariaDB!
