I think our big moment has arrived.
0:03
We're finally ready to make this thing actually listen on the network
0:06
and do what it is supposed to do.
0:08
So with everything set up the ssl right here, security right here,
0:15
also not default port right there, firewall in place, all these things
0:20
let's change that to the glorious 0.0.0.0
0:24
now, let's restart the server, see if it liked it,
0:30
excellent it definitely liked it;
0:33
see if we can still connect to it here on our local machine— we can,
0:38
everything seems to be working well.
0:42
It's now listening at least on local host, let's go over here to this one,
0:45
now here's all the connection info we got built up,
0:49
port, certificates, username, password, auth db, let's go add one more thing,
0:57
because obviously local host is not where this server is running.
1:01
So we are going to add host and put the ip address of the Mongo server,
1:08
the moment of truth—we're in, look at that
1:13
now, that's pretty cool, we could even do stuff on it,
1:17
let me go over you and copy this and let's try one more thing,
1:20
maybe we've screwed up somehow,
1:22
maybe something super bad is happening here and this is just wide open,
1:26
let's try to connect to it, notice I am on my Mac book,
1:29
I'm not on the web server or the Mongo server, I'm on my Mac book
1:34
and timing, timing, it's timing out, ta-da, that's awesome, that's what you want,
1:40
no connection possible, we couldn't connect to this
1:44
because why— only that one server magically gets to connect to it, beautiful.
1:48
And of course, we saw that we have to pass this auth stuff right,
1:52
for some reason we don't pass that.
2:00
We still can connect as you saw, but we can't do anything whatsoever
2:04
so I am not sure if I like that, I kind of would prefer
2:07
that you can't even connect unless you just go through the authentication step
2:11
but I guess more or less the same thing.
2:15
So exit out and now we're back, working,
2:18
because I ran the one that passed username and password,
2:21
so this configuration of this little fake web server
2:25
and this not fake Mongo server is running.
2:30
Let's do one more thing, let's say pip install glances
2:34
but we don't have pip, so apt install glances, let's skip that,
2:41
like this, it's going to take a moment,
2:45
so glances is pretty heavyweight, you may or may not want to install it
2:47
but it's a really cool way to look at our server,
2:50
so if we come over here and look around, it will show us things like
2:54
how much memory our server is using, right now 15 percent.
2:57
If we want to know how much cpu it's using, not much at all,
3:02
right now we're sorting by cpu and here you can see
3:05
Mongo is here just kind of hanging out that's 0.6 cpu
3:08
like it must be doing some maintenance on itself,
3:11
you can sort by memory and it will almost always put MongoDB at the top
3:15
so over here you can see it's using really in terms of resident memory
3:20
only six percent, that's not much but it has no data in it.
3:24
So we'll come over here and we'll use this glances program
3:27
to have a look at Mongo, maybe later we could load it up
3:31
with this big dealership database that has the 1.5 million records or so in it.
