WEBVTT 00:00:01.040 --> 00:00:03.760 Welcome to this demo clip, setting up Squid. 00:00:04.440 --> 00:00:07.050 In this clip, you'll see how to download Squid, 00:00:07.840 --> 00:00:12.860 how to build Squid from source, and how to start Squid using Docker. 00:00:13.540 --> 00:00:14.460 Let's get started. 00:00:14.840 --> 00:00:18.570 So first things first, you'll want to head over to Squid's website, 00:00:18.660 --> 00:00:23.560 squid‑cache.org. From here, you can click on the Download button. 00:00:25.040 --> 00:00:28.490 This takes you to Squid's download page from which you can download 00:00:28.500 --> 00:00:30.160 every available version of Squid. 00:00:30.640 --> 00:00:36.310 You'll want to grab the latest stable version of Squid here. From 00:00:36.310 --> 00:00:42.220 this page, we can go ahead and download the source code. If you don't 00:00:42.220 --> 00:00:45.230 want to build from source, binaries are available for a number of 00:00:45.230 --> 00:00:48.820 different distributions. Now that we have the source code, let's see 00:00:48.820 --> 00:00:53.100 how we can build Squid from source so that we can begin to use it. In 00:00:53.100 --> 00:00:53.680 this course, 00:00:53.680 --> 00:00:55.900 we've selected to use Docker in order to make 00:00:55.900 --> 00:00:57.760 building and running Squid very easy. 00:00:58.440 --> 00:01:02.180 Let's take a look at our Dockerfile. We'll be using a stable version of 00:01:02.180 --> 00:01:05.250 Ubuntu as our operating system and base image here. 00:01:06.140 --> 00:01:08.790 Now we set some environment variables including the 00:01:08.790 --> 00:01:13.820 SQUID_VERSION, and a bit further down, the caching and log 00:01:13.820 --> 00:01:17.130 directories that Squid will use. Here, we copy in the 00:01:17.130 --> 00:01:19.160 downloaded source code that we grabbed earlier. 00:01:20.340 --> 00:01:22.460 Now here are the really important bits. 00:01:22.940 --> 00:01:25.760 First, we install the needed dependencies to build Squid. 00:01:26.340 --> 00:01:31.950 As you can see, we need to C/C++ compiler, in this case, gcc and make. 00:01:32.640 --> 00:01:37.300 Now, we need to run the configure script found within the Squid source 00:01:37.300 --> 00:01:41.520 code to prepare Squid for building. The configure script has a number of 00:01:41.520 --> 00:01:44.190 different options that we can take advantage of when it comes to 00:01:44.190 --> 00:01:46.460 customizing your specific build of Squid. 00:01:46.940 --> 00:01:51.650 And finally, we run make install to install Squid. For a full listing of 00:01:51.650 --> 00:01:54.260 instructions on how to build Squid on several different operating 00:01:54.260 --> 00:01:57.380 systems and for a listing of available options, 00:01:57.390 --> 00:02:04.600 check out this URL. Now, we can set the script we want to run on startup 00:02:04.610 --> 00:02:07.650 and expose the port that we would like Squid to run on. 00:02:08.740 --> 00:02:12.950 If we check out this entrypoint.sh file really quickly, we 00:02:12.950 --> 00:02:16.690 can see that it simply starts Squid, passing in the path to 00:02:16.690 --> 00:02:18.660 the appropriate squid.conf file. 00:02:19.440 --> 00:02:22.750 Now we can run docker build to build the image. 00:02:23.740 --> 00:02:27.540 This may take a while if it's your first time running this command, as Squid 00:02:27.540 --> 00:02:30.460 is being built from source and it's a rather large project. 00:02:31.140 --> 00:02:32.400 Once that's complete, 00:02:32.660 --> 00:02:38.820 we can run a container based on this new image we've created. And as you 00:02:38.820 --> 00:02:42.560 can see, Squid is running within this container. Awesome. 00:02:43.240 --> 00:02:45.670 This is a start. In the next demo, 00:02:45.670 --> 00:02:49.340 we'll actually learn about how to configure Squid, an important step if 00:02:49.340 --> 00:02:51.390 we're going to learn how to take advantage of the different 00:02:51.390 --> 00:02:54.550 authentication and access controls that Squid provides.
