Lecture: The BIG moment

0:01 I think our big moment has arrived. We're finally ready to make this thing actually listen on the network and do what it is supposed to do.
0:09 So with everything set up the ssl right here, security right here, also not default port right there, firewall in place, all these things
0:21 let's change that to the glorious now, let's restart the server, see if it liked it, excellent it definitely liked it;
0:34 see if we can still connect to it here on our local machine— we can, everything seems to be working well.
0:43 It's now listening at least on local host, let's go over here to this one, now here's all the connection info we got built up,
0:50 port, certificates, username, password, auth db, let's go add one more thing, because obviously local host is not where this server is running.
1:02 So we are going to add host and put the ip address of the Mongo server, the moment of truth—we're in, look at that
1:14 now, that's pretty cool, we could even do stuff on it, let me go over you and copy this and let's try one more thing, maybe we've screwed up somehow,
1:23 maybe something super bad is happening here and this is just wide open, let's try to connect to it, notice I am on my Mac book,
1:30 I'm not on the web server or the Mongo server, I'm on my Mac book and timing, timing, it's timing out, ta-da, that's awesome, that's what you want,
1:41 no connection possible, we couldn't connect to this because why— only that one server magically gets to connect to it, beautiful.
1:49 And of course, we saw that we have to pass this auth stuff right, for some reason we don't pass that.
2:01 We still can connect as you saw, but we can't do anything whatsoever so I am not sure if I like that, I kind of would prefer
2:08 that you can't even connect unless you just go through the authentication step but I guess more or less the same thing.
2:16 So exit out and now we're back, working, because I ran the one that passed username and password, so this configuration of this little fake web server
2:26 and this not fake Mongo server is running. Let's do one more thing, let's say pip install glances
2:35 but we don't have pip, so apt install glances, let's skip that, like this, it's going to take a moment,
2:46 so glances is pretty heavyweight, you may or may not want to install it but it's a really cool way to look at our server,
2:51 so if we come over here and look around, it will show us things like how much memory our server is using, right now 15 percent.
2:58 If we want to know how much cpu it's using, not much at all, right now we're sorting by cpu and here you can see
3:06 Mongo is here just kind of hanging out that's 0.6 cpu like it must be doing some maintenance on itself,
3:12 you can sort by memory and it will almost always put MongoDB at the top so over here you can see it's using really in terms of resident memory
3:21 only six percent, that's not much but it has no data in it. So we'll come over here and we'll use this glances program
3:28 to have a look at Mongo, maybe later we could load it up with this big dealership database that has the 1.5 million records or so in it.
