WEBVTT 00:00.110 --> 00:00.540 Here. 00:00.650 --> 00:01.520 And welcome back. 00:01.520 --> 00:06.710 In today's video, we will look into how we can build static modules in Nginx. 00:06.740 --> 00:14.180 Now, we have already looked about how the dynamic modules work practically in Nginx, where you first 00:14.180 --> 00:20.540 compile the module and then you reference it with a load module directive followed by the module path. 00:20.540 --> 00:22.550 So this was pretty straightforward. 00:22.550 --> 00:28.460 And in dynamic configuration you don't really have to recompile your nginx version. 00:28.460 --> 00:31.490 So your Nginx version in production remains the same. 00:31.490 --> 00:37.460 The only thing that you're doing is you're compiling the module by itself and then referencing it within 00:37.460 --> 00:39.020 the nginx configuration. 00:39.020 --> 00:42.290 So the nginx binary remains untouched. 00:42.320 --> 00:46.040 However, in static modules things are a little different. 00:46.040 --> 00:53.390 So static modules are compiled into the Nginx server binary at compile time. 00:53.390 --> 00:59.360 So whenever you are compiling your Nginx, you have to reference the module there. 00:59.360 --> 01:02.280 Whenever you are discussing about the static modules. 01:02.280 --> 01:09.240 So it is not like you already have the nginx binary compiled and running in production and then you 01:09.240 --> 01:10.980 want to add one more module there. 01:10.980 --> 01:15.840 So as far as static modules are concerned, that really is not really the approach there. 01:15.840 --> 01:19.670 So let's look into the steps which are required for building static modules. 01:19.680 --> 01:25.380 First is to fetch the Nginx source, second is to fetch the module source. 01:25.380 --> 01:32.610 So this two step remains similar and the step three is to build the static module along with Nginx. 01:32.640 --> 01:36.180 Now for dynamic module we only use to build dynamic module. 01:36.180 --> 01:42.750 However, for static module you will have to build the nginx itself because here the nginx is also compiled. 01:42.750 --> 01:45.540 So let's look into the steps which are required. 01:45.540 --> 01:45.870 Now. 01:45.870 --> 01:48.990 In the previous video we had built the dynamic module. 01:48.990 --> 01:54.930 Now if you do a nginx hyphen V, you will not really see that specific helloworld module because it 01:54.930 --> 02:00.930 is dynamic and whatever module that you generally reference, here are the static modules. 02:00.930 --> 02:04.350 So in today's video we'll be building static modules. 02:04.350 --> 02:06.900 So in order to do that, let's do one thing. 02:06.900 --> 02:09.360 Let's quickly verify the status of Nginx. 02:09.360 --> 02:10.380 It is running. 02:10.890 --> 02:22.590 I'll stop the Nginx service and I'll remove the Nginx directory and I'll also remove the nginx binary 02:22.590 --> 02:23.450 by itself. 02:23.460 --> 02:25.230 All right, great. 02:25.410 --> 02:29.490 So now let's go to the Nginx demo directory. 02:29.490 --> 02:38.100 We'll go to Nginx one point 16.0 and here during the configuration option we'll use the same configuration 02:38.100 --> 02:44.010 option which you remember we had done while building Nginx from source. 02:44.010 --> 02:48.360 So while compiling Nginx from source we had run this specific command. 02:48.360 --> 02:50.250 We'll use the same command here. 02:50.430 --> 02:55.530 In addition, we have to also specify the static module here. 02:55.680 --> 03:01.260 Now, basically if you look into the Hello world we already discussed about the dynamic module this 03:01.260 --> 03:03.720 time we have to see the static module. 03:03.720 --> 03:08.220 So the static module here, the only difference is you remove the dynamic here. 03:08.220 --> 03:11.550 So this is Add module followed by the module path. 03:11.550 --> 03:16.260 And for dynamic module you have add dynamic module followed by the module path. 03:16.260 --> 03:19.050 And basically this command remains the same. 03:19.050 --> 03:21.960 It is not just specific to the Hello World module. 03:21.960 --> 03:26.280 Any other module you will build, the overall process remains the same. 03:26.280 --> 03:31.410 The only thing that will change is the config file here as well as the module file. 03:31.410 --> 03:33.450 So let's try this out. 03:33.450 --> 03:41.490 So I'll say hyphen, hyphen hyphen module and let's specify the module path which is. 03:44.640 --> 03:45.650 Let's go better. 03:45.660 --> 03:50.040 Let's get the exact directory name where the module config is present. 03:53.270 --> 03:53.600 All right. 03:53.600 --> 03:55.330 So this is the exact path. 03:55.340 --> 03:58.790 So now together, we'll copy this entire command. 03:58.820 --> 04:02.870 We'll go back to the Nginx source directory and we'll run this command. 04:04.580 --> 04:11.600 So this will go ahead and not only build your nginx binary, but this binary will have the static module 04:11.600 --> 04:13.050 that we had referenced. 04:13.070 --> 04:15.710 So the next command would be make. 04:16.970 --> 04:19.490 And the last command would be make install. 04:20.960 --> 04:21.520 Great. 04:21.530 --> 04:27.280 So now if you go to the Nginx directory, these are the configuration files. 04:27.290 --> 04:29.810 Let's go ahead and start Nginx. 04:30.980 --> 04:31.340 All right. 04:31.340 --> 04:37.970 And if you do a nginx hyphen v here, you will see that there is one more parameter which is add module 04:37.970 --> 04:40.910 which is your Hello world module here. 04:41.150 --> 04:47.990 So now you don't really have to do a load module directive that we had done typically during the dynamic 04:47.990 --> 04:48.780 module time. 04:48.830 --> 04:55.170 So in order to verify, let's open up the Nginx configuration and let's go a bit down and we'll copy 04:55.170 --> 04:58.930 the same server block that we had used during the dynamic module. 04:58.950 --> 05:01.920 So this is the same server block that we had used. 05:01.950 --> 05:04.380 Now here we are not doing load module. 05:04.950 --> 05:06.960 So now let's quickly verify. 05:07.170 --> 05:09.350 Everything seems to be working perfectly. 05:09.390 --> 05:11.100 Let's restart Nginx. 05:11.700 --> 05:12.450 All right. 05:12.450 --> 05:19.880 So now if you do a curl on localhost colon 8080, you should see hello world as expected. 05:19.890 --> 05:26.940 So I hope at a high level overview you understood what static modules are and you also understood what 05:26.940 --> 05:28.120 dynamic modules are. 05:28.140 --> 05:30.960 So with this, we'll conclude this video. 05:30.990 --> 05:34.920 I hope this video has been informative for you and I look forward to see you in the next video.
