1 00:00:00,000 --> 00:00:14,720 Hey everyone and welcome back. 2 00:00:14,720 --> 00:00:19,339 So now what we're doing is we are back on our client machine. 3 00:00:19,339 --> 00:00:24,339 Now what I've actually done here is I have rebooted that machine. 4 00:00:24,339 --> 00:00:32,340 So if I happen to issue a DF-H, you will notice that we have no longer mounted the 5 00:00:32,340 --> 00:00:37,100 network file share that we are getting from the NFS server. 6 00:00:37,100 --> 00:00:43,579 Now think about this, what if we wanted to boot up our machine and have immediate access 7 00:00:43,579 --> 00:00:45,340 to that particular share? 8 00:00:45,340 --> 00:00:49,039 Well the reality lies in being able to configure persistence. 9 00:00:49,039 --> 00:00:55,740 Now if I had to pop quiz you and ask you what file do you think we should modify to invoke 10 00:00:55,740 --> 00:00:59,759 some type of persistent mounting of a file system? 11 00:00:59,759 --> 00:01:04,480 Well hopefully you will remember that we have a configuration file called FSTab within the 12 00:01:04,480 --> 00:01:05,840 Etsy directory. 13 00:01:05,840 --> 00:01:10,920 That is absolutely where we are going to make this configuration so that we can have such 14 00:01:10,920 --> 00:01:12,759 a persistent connection. 15 00:01:12,759 --> 00:01:17,359 So before I do anything like I say I will show you my mount directory. 16 00:01:17,359 --> 00:01:23,079 We still have the my share directory we created where we were actually mounting our network 17 00:01:23,079 --> 00:01:24,079 file system. 18 00:01:24,079 --> 00:01:29,120 But if I do an LS notice that those particular files that we created, file 1 and file 2 are 19 00:01:29,120 --> 00:01:32,879 not accessible, that is because we have not got the mount in action. 20 00:01:32,879 --> 00:01:37,879 Now again of course we do realise we can just manually mount the file system with the mount 21 00:01:37,879 --> 00:01:42,359 command as we did before and I could help if I could spell mount correctly. 22 00:01:42,359 --> 00:01:43,359 There we go. 23 00:01:43,359 --> 00:01:49,439 And obviously that can be a little bit inefficient if we want to be using this very very regularly. 24 00:01:49,439 --> 00:01:53,000 So what we will do here is we will go in and do sudo nano. 25 00:01:53,000 --> 00:01:55,780 I am going to Etsy and then I will go into FSTab. 26 00:01:55,780 --> 00:01:57,840 So let me type in the password here. 27 00:01:57,840 --> 00:02:01,359 Cool so let me actually just full screen this so it looks a little bit neater. 28 00:02:01,359 --> 00:02:02,359 There we go. 29 00:02:02,359 --> 00:02:06,239 So what I am going to do here is I am going to follow the same format. 30 00:02:06,239 --> 00:02:12,000 What I will do is I will give the IP address of the server that I am trying to reach to 31 00:02:12,000 --> 00:02:19,520 remember that will be the NFS server which has the IP address 192.1680.44. 32 00:02:19,520 --> 00:02:20,520 Let me just confirm that. 33 00:02:20,520 --> 00:02:21,520 Let's do an IP adder. 34 00:02:21,520 --> 00:02:26,639 Yep we can see right here 192.1680.44 that is correct. 35 00:02:26,639 --> 00:02:31,000 So back onto the client right here and then we will do a colon then a forward slash and 36 00:02:31,000 --> 00:02:32,560 then the name of the share. 37 00:02:32,560 --> 00:02:35,879 Now the share we created was simply called my share. 38 00:02:35,879 --> 00:02:40,520 And now what I want to do is I want to specify where it is I am going to mount this. 39 00:02:40,520 --> 00:02:45,680 I am going to mount it in the MNT directory on my system within the directory I created 40 00:02:45,680 --> 00:02:47,120 called my share. 41 00:02:47,120 --> 00:02:50,600 And then I want to specify the file system type which will be NFS. 42 00:02:50,600 --> 00:02:55,480 And now I can specify the different options that I want to invoke here. 43 00:02:55,480 --> 00:03:01,200 Now I am just going to use the defaults and then I will have my values 0 and 0. 44 00:03:01,200 --> 00:03:04,120 If you do recall these values relate to things such as FISC. 45 00:03:04,120 --> 00:03:06,120 We don't need to worry about that so much right now. 46 00:03:06,319 --> 00:03:11,120 Within these defaults here we can actually specify different options if we so wish. 47 00:03:11,120 --> 00:03:16,719 We can specify something called say for example a soft mount meaning that if the server isn't 48 00:03:16,719 --> 00:03:22,520 actually reachable for whatever reason that may be soft mount will stop attempting to mount 49 00:03:22,520 --> 00:03:24,480 that network file system. 50 00:03:24,480 --> 00:03:30,400 Whereas if we specify a hard mount even if the server is not reachable hard mount is 51 00:03:30,400 --> 00:03:35,000 going to specify that we keep trying and trying and trying until we have reached a 52 00:03:35,000 --> 00:03:37,000 certain given timeout. 53 00:03:37,000 --> 00:03:40,120 A timeout by the way that we can control and specify. 54 00:03:40,120 --> 00:03:44,560 But for now we are not going to worry too much about those particular configurations. 55 00:03:44,560 --> 00:03:46,800 Understand they do exist be aware of them. 56 00:03:46,800 --> 00:03:48,759 But for now we will just leave the defaults. 57 00:03:48,759 --> 00:03:54,719 So now what we have here is we have specified the server plus its share name. 58 00:03:54,719 --> 00:03:57,360 We specify whereabouts we want to mount it. 59 00:03:57,360 --> 00:04:00,240 The file system with some default values. 60 00:04:00,240 --> 00:04:07,159 But if I happen to just save this right now and I escape out again I do a DFH nothing 61 00:04:07,159 --> 00:04:09,600 has actually changed quite just yet. 62 00:04:09,600 --> 00:04:17,040 What I can do though is I can run the mount-a command or I could reboot my system either 63 00:04:17,040 --> 00:04:19,840 or as fine so I will just use mount a. 64 00:04:19,840 --> 00:04:23,720 That is going to pull in the configurations that we get from fstab. 65 00:04:23,720 --> 00:04:30,480 If I try running this command once again notice now that we have indeed actually got access 66 00:04:30,480 --> 00:04:36,280 to that share mounted over the network and if I go into my mount directory and into my 67 00:04:36,280 --> 00:04:41,960 share we do an ls suddenly those files are once again accessible. 68 00:04:41,960 --> 00:04:47,440 And if I happen to just reboot my system do a telnet 6 for a reboot give it a little minutes 69 00:04:47,440 --> 00:04:50,360 so we will go and open up a terminal. 70 00:04:50,360 --> 00:04:58,000 What I will do is immediately do a DF-H and we can see here indeed the share has been 71 00:04:58,000 --> 00:05:04,520 automatically mounted and we do have persistence if I go in to my MNT directory and into my 72 00:05:04,520 --> 00:05:12,199 share clearly we have access to our files from our file system across the network via the 73 00:05:12,199 --> 00:05:14,040 NFS server. 74 00:05:14,040 --> 00:05:18,480 So that's how we can configure our clients to have persistent mounting and access to 75 00:05:18,480 --> 00:05:22,060 those shares over the network I hope this has been informative for you and I would like 76 00:05:22,060 --> 00:05:23,360 to thank you for viewing.
