1
00:00:02,280 --> 00:00:07,830
So there's a bunch of stuff we can configure and what exactly can we configure there or what could

2
00:00:07,830 --> 00:00:09,080
be interesting to us?

3
00:00:09,360 --> 00:00:15,090
Well things like quiet allow you to change the way things get logged or output by the server

4
00:00:15,120 --> 00:00:19,430
and if you feel like it's talking too much to you, you can control that with quiet

5
00:00:19,680 --> 00:00:25,520
and obviously check out the official docs for more detailed explanations of all the options. Interesting

6
00:00:25,520 --> 00:00:34,130
to us is the log path and also another setting, the db path which you can find a bit further down towards

7
00:00:34,130 --> 00:00:35,390
the end of this list.

8
00:00:35,690 --> 00:00:42,350
These two path allow you to configure where your data gets stored in the case of db path because

9
00:00:42,370 --> 00:00:47,020
mongodb of course does write your data to real files on your system,

10
00:00:47,150 --> 00:00:52,970
so the db path is where these files will live and the log path is essentially where the logs will

11
00:00:52,970 --> 00:00:58,340
be written to and the logs are interesting because in the logs, you can then see for example warnings

12
00:00:58,340 --> 00:01:01,370
of json schema validation, warnings

13
00:01:01,370 --> 00:01:08,960
if you set the validation action to warning, what we did in a previous module. So log path and db

14
00:01:08,960 --> 00:01:10,220
path can be set,

15
00:01:10,220 --> 00:01:12,130
now how do we set this?

16
00:01:12,200 --> 00:01:16,280
I'm in my mongodb folder and there, I got that bin folder

17
00:01:16,280 --> 00:01:22,060
Now in this mongodb folder, I'll create a new path and I'll name it db and I'll create another

18
00:01:22,070 --> 00:01:24,360
new folder and I'll name it

19
00:01:24,390 --> 00:01:27,610
logs, you can name these folders however you want.

20
00:01:27,620 --> 00:01:33,140
Now these are two new folders and I want to use the db folder for my db files and the logs folder

21
00:01:33,140 --> 00:01:40,310
for my logs, the default setting for db is that it will use my root folder and there, the data db folder,

22
00:01:40,370 --> 00:01:42,490
that is the default setting of mongodb

23
00:01:42,530 --> 00:01:47,240
and if you start a mongod instance without any additional setting, it will use that folder

24
00:01:47,480 --> 00:01:51,550
but you can tell it to use another folder. And the same is true for the logs,

25
00:01:51,560 --> 00:01:58,220
you can tell it to not output its log messages in the window where you started the mongod's instance

26
00:01:58,490 --> 00:02:00,410
but instead into a separate file

27
00:02:00,440 --> 00:02:04,150
and I want to do these two things. Now on Mac,

28
00:02:04,160 --> 00:02:12,200
I can get the path to my db folder by clicking on it with a right click and then get info and then copying

29
00:02:12,200 --> 00:02:14,700
that path, on windows in the explorer,

30
00:02:14,720 --> 00:02:19,700
you can of course just copy that url by clicking into it once it becomes a full url and

31
00:02:19,700 --> 00:02:21,080
then copying that.

32
00:02:21,470 --> 00:02:28,540
And now if I want to start my mongodb server with that path being used, I can run sudo mongod

33
00:02:28,670 --> 00:02:34,040
or on Windows, it would just be Mongod --dbpath like this,

34
00:02:34,190 --> 00:02:35,000
then a blank

35
00:02:35,120 --> 00:02:39,620
and then the path. And now important, I just copied the path to my mongodb folder,

36
00:02:39,620 --> 00:02:47,570
of course I should point to the slash db folder, on windows its /db. Hit enter and enter your

37
00:02:47,570 --> 00:02:48,840
password if you have to

38
00:02:48,890 --> 00:02:54,560
And this should bring up your mongod server as it worked in the past but now you should see that in

39
00:02:54,560 --> 00:02:59,930
the db folder, it created a bunch of files because now it's storing the data here and therefore this is

40
00:02:59,930 --> 00:03:04,290
now using a totally different database storage than it previously did,

41
00:03:04,340 --> 00:03:07,130
it's totally detached from our old database path,

42
00:03:07,130 --> 00:03:12,620
we have a brand new database set up now because we're using a different file storage for the database

43
00:03:12,620 --> 00:03:16,430
files. Now logging would also be interesting,

44
00:03:16,430 --> 00:03:20,350
so let me quickly clear the window to make it easier to read,

45
00:03:20,360 --> 00:03:24,490
let me quickly rerun sudo mongod here with db path

46
00:03:24,710 --> 00:03:30,220
but I'll set an additional flag separated with a blank and then --logpath

47
00:03:30,590 --> 00:03:33,760
and now I want to use almost the same path,

48
00:03:35,230 --> 00:03:35,960
this one,

49
00:03:36,270 --> 00:03:43,270
however it should be /logs and and that's important to know, the logs, the log path needs the path

50
00:03:43,290 --> 00:03:44,970
to a log file,

51
00:03:45,180 --> 00:03:51,860
so here you could add log.log for example. If you hit enter,

52
00:03:51,980 --> 00:03:57,770
this now starts the server but you see way less output here because now if you look into logs, you should

53
00:03:57,770 --> 00:03:59,660
have a log.log file,

54
00:03:59,660 --> 00:04:02,200
now all the output gets written into that file

55
00:04:02,360 --> 00:04:06,860
and that of course can be useful because now this file will get saved and you can always come back

56
00:04:06,860 --> 00:04:07,320
to it,

57
00:04:07,400 --> 00:04:09,590
check your logs from yesterday,

58
00:04:09,590 --> 00:04:10,720
go through it,

59
00:04:10,850 --> 00:04:16,430
see any warnings or errors you might have in there, like this warning that access control is not enabled

60
00:04:16,490 --> 00:04:19,330
which is the default right now, we got no authentication,

61
00:04:19,370 --> 00:04:20,450
we'll add it later.

62
00:04:20,690 --> 00:04:22,690
So this can be useful for

63
00:04:22,820 --> 00:04:30,810
well persist and error searching or for simply persistent and auditing of your server.

64
00:04:31,160 --> 00:04:37,250
So this now is how you can set a custom path for your logs and how you can set a custom path for your

65
00:04:37,250 --> 00:04:39,370
database. What else can we do?
