Hello from Docker!
10
This message shows that your installation appears to be working correctly.
11

12
To generate this message, Docker took the following steps:
13
 1. The Docker client contacted the Docker daemon.
14
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
15
    (amd64)
16
 3. The Docker daemon created a new container from that image which runs the
17
    executable that produces the output you are currently reading.
18
 4. The Docker daemon streamed that output to the Docker client, which sent it
19
    to your terminal.
20

21
To try something more ambitious, you can run an Ubuntu container with:
22
 $ docker run -it ubuntu bash

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

      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

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
haven't set the root password yet, you should just press enter here.
9

10
Enter current password for root (enter for none):
11
OK, successfully used password, moving on...
12

13
Setting the root password or using the unix_socket ensures that nobody
14
can log into the MariaDB root user without the proper authorisation.
15

16
You already have your root account protected, so you can safely answer 'n'.
17

18
Switch to unix_socket authentication [Y/n] n
19
 ... skipping.
20

21
You already have your root account protected, so you can safely answer 'n'.
22

23
Change the root password? [Y/n]
24
New password:
25
Re-enter new password:
26
Password updated successfully!
27
Reloading privilege tables..
28
 ... Success!

31
By default, a MariaDB installation has an anonymous user, allowing anyone
32
to log into MariaDB without having to have a user account created for
33
them.  This is intended only for testing, and to make the installation
34
go a bit smoother.  You should remove them before moving into a
35
production environment.
36

37
Remove anonymous users? [Y/n]
38
 ... Success!
39

40
Normally, root should only be allowed to connect from 'localhost'.  This
41
ensures that someone cannot guess at the root password from the network.
42

43
Disallow root login remotely? [Y/n]
44
 ... Success!
45

46
By default, MariaDB comes with a database named 'test' that anyone can
47
access.  This is also intended only for testing, and should be removed
48
before moving into a production environment.
49

50
Remove test database and access to it? [Y/n]
51
 - Dropping test database...
52
 ... Success!
53
 - Removing privileges on test database...
54
 ... Success!
55

56
Reloading the privilege tables will ensure that all changes made so far
57
will take effect immediately.
58

59
Reload privilege tables now? [Y/n]
60
 ... Success!
61

62
Cleaning up...
63

64
All done!  If you've completed all of the above steps, your MariaDB
65
installation should now be secure.

67
Thanks for using MariaDB!
