0:06 Welcome to this IT Explainer video, part of our Maintenance Tools topic range.
0:11 In this video we’ll cover the subject of Memcached in SLM.
0:16 SLM leverages memcached as its caching tool to speed up the application.
0:20 Memcached is a high performance distributed memory object caching system, generic in nature, but originally intended for using speeding up dynamic web applications by alleviating database load.
0:34 The following information will be covered in this training.
0:36 Chapter one will be Memcached on Windows, and chapter 2 will be Memcached on Linux container.
0:47 In chapter 1 we’ll cover installation, starting, stopping and uninstallation in Windows.
0:54 For this exercise, we’ll need the following two files.
0:57 These will be provided to you with the installation pack.
1:00 So once we have the folder extracted, we’ll open up a command prompt.
1:04 This needs to be in elevated permissions.
1:07 So if we right click and click Run as administrator and then we have a couple of commands that we need to type in, but this will be provided to you.
1:14 You can simply copy and paste these two commands into the command prompt.
1:25 So this is the first command that’s provided in the documentation.
1:29 So once you’ve copied and pasted this, you just need to hit enter and you can see it’s successful.
1:34 The scheduled task memcached has successfully been created and then to run the memcached we need to copy and paste the second command.
1:45 So this will run the memcached.
1:47 Now that to stop it, there’s a command to stop instead of run.
1:51 We just edit this command and put end and hit return and we can see this has successfully stopped the command.
1:59 And if we need to remove the task, we just change end to delete, hit return.
2:08 It asks if you’re sure you want to delete, just type Y and hit return.
2:12 And now memcached was successfully deleted.
2:18 In Chapter 2 we will cover starting, stopping, restarting, and the configuration file in Linux.
2:26 Memcached in the Linux container is already installed in the setup.
2:29 So we’re just going to look at how to Start, Stop and restart memcached.
2:35 So to start memcached we just type service space memcached space start and we can see that started the memcached.
2:44 To stop the memcached we change this to stop and hit return and to restart it’s service memcached restart.
2:53 It’s just restarted now.
2:54 Now to edit the config file of the memcached, let’s just clear the screen.
2:59 So to edit the memcached config file we go to vim etc.
3:06 Memcached dot conf.
3:08 When the container image is deployed, it’s all already there for you.
3:11 But the log file is located in this directory var log memcache dot log.
3:18 The memory is default, the port is default.
3:21 Username is memcache.
3:23 The IP address for the memcache server is just a local IP address, so it’s 127.0.0.1 and we’re using a PID file to run the memcached and that’s all the required information for the memcached container.
