Linux Server. Kurs video. Usługi serwerowe, skrypty i środowisko graficzne
Adam Raźniewski
Obierz kurs na... wydajność i bezpieczeństwo Systemy oparte na Linuksie stanowią świetną alternatywę dla Windowsa. Szczególnie dobrze sprawdzają się w środowiskach serwerowych, dla których wsparcie zapewniają największe firmy komputerowe, takie jak IBM, Oracle, Dell czy Microsoft. Tak, także ta ostatnia korporacja docenia zalety oprogramowania Linux — w 2016 roku Microsoft podarował 500 000 dolarów dla The Linux Foundation. Wieloletnia obecność na rynku informatycznym, nieustanna dbałość o rozwój linuksowego oprogramowania oraz jego otwartość skutkują nie tylko dużą wydajnością Linuksa używanego do celów serwerowych, lecz także wysokim stopniem bezpieczeństwa zastosowanych rozwiązań. Wymienione zalety Linuksa oraz powszechność bazującego na nim Androida czynią ten system operacyjny niezwykle popularnym. Tym samym zapotrzebowanie na administratorów linuksowych serwerów jest ogromne — i stale rośnie. O ile jednak użytkownikowi wystarczy umiejętność poruszania się „po powierzchni”, o tyle administrator musi wejść głębiej — umieć samodzielnie dodawać usługi serwerowe i zdalnie poruszać się w środowisku. Przyda mu się umiejętność instalowania systemów operacyjnych, pisania skryptów automatyzujących oraz świadomość tego, jak dbać o bezpieczeństwo i pilnować, by nikt niepowołany nie włamał się na serwer. Wszystko po to, by móc na co dzień używać tego w pełni darmowego systemu. Co Cię czeka w trakcie naszego profesjonalnego szkolenia? Podczas pracy z tym kursem video: dowiesz się, jak zainstalować system operacyjny; rozpoczniesz graficzną podróż po środowisku Linux Server; nauczysz się obsługi terminala; poznasz skrypty shellowe i najważniejsze usługi serwerowe. Co więcej... będziesz zarządzać wieloma serwerami, wykrywać i rozwiązywać problemy. Linux Server. Kurs video. Usługi serwerowe, skrypty i środowisko graficzne kończy się na poziomie podstawowym. Jego celem jest nauczenie uczestnika szkolenia bazowej, graficznej i konsolowej obsługi systemu Linux. Świetna alternatywa dla Windowsa Co takiego ma Linux, czego nie są w stanie zaoferować inne systemy? Pierwsza, podstawowa odpowiedź na to pytanie zawiera się właściwie w jednym słowie: wolność. Zakup licencji na Windowsa wiąże się z wieloma ograniczeniami. Nie można go rozpowszechniać na kolejne komputery, oczywiście nie wolno także ingerować w kod źródłowy. Z Linuksem rzecz ma się całkowicie inaczej — wolne oprogramowanie dowolnie rozpowszechnisz, w razie potrzeby dostosujesz je również do własnych potrzeb. W dodatku nie tylko Ty będziesz to robić — nad usprawnieniami, poprawą bezpieczeństwa i kolejnymi usługami dla Linuksa pracuje sztab ludzi na całym świecie. O jakość oprogramowania dba także The Linux Foundation — jeśli wybierzesz Linux Server, nigdy nie zostaniesz bez wsparcia!

Linux Service Management Made Easy with systemd will provide you with an in-depth understanding of systemd, so that you can set up your servers securely and efficiently.This is a comprehensive guide for Linux administrators that will help you get the best of systemd, starting with an explanation of the fundamentals of systemd management.You’ll also learn how to edit and create your own systemd units, which will be particularly helpful if you need to create custom services or timers and add features or security to an existing service. Next, you'll find out how to analyze and fix boot-up challenges and set system parameters. An overview of cgroups that'll help you control system resource usage for both processes and users will also be covered, alongside a practical demonstration on how cgroups are structured, spotting the differences between cgroups Version 1 and 2, and how to set resource limits on both. Finally, you'll learn about the systemd way of performing time-keeping, networking, logging, and login management. You'll discover how to configure servers accurately and gather system information to analyze system security and performance. By the end of this Linux book, you’ll be able to efficiently manage all aspects of a server running the systemd init system.
Linux Shell Scripting Bootcamp. The fastest way to learn Linux shell scripting
James K Lewis
Linux Shell Scripting Bootcamp is all about learning the essentials of script creation, validating parameters, and checking for the existence of files and other items needed by the script.We will use scripts to explore iterative operations using loops and learn different types of loop statements, with their differences. Along with this, we will also create a numbered backup script for backup files.Further, you will get well-versed with how variables work on a Linux system and how they relate to scripts. You’ll also learn how to create and call subroutines in a script and create interactive scripts. The most important archive commands, zip and tar, are also discussed for performing backups. Later, you will dive deeper by understanding the use of wget and curl scripts and the use of checksum and file encryption in further chapters.Finally, you will learn how to debug scripts and scripting best practices that will enable you to write a great code every time! By the end of the book, you will be able to write shell scripts that can dig data from the web and process it efficiently.

Linux is the world's most popular open source operating system (OS). Linux System Programming Techniques will enable you to extend the Linux OS with your own system programs and communicate with other programs on the system.The book begins by exploring the Linux filesystem, its basic commands, built-in manual pages, the GNU compiler collection (GCC), and Linux system calls. You'll then discover how to handle errors in your programs and will learn to catch errors and print relevant information about them. The book takes you through multiple recipes on how to read and write files on the system, using both streams and file descriptors. As you advance, you'll delve into forking, creating zombie processes, and daemons, along with recipes on how to handle daemons using systemd. After this, you'll find out how to create shared libraries and start exploring different types of interprocess communication (IPC). In the later chapters, recipes on how to write programs using POSIX threads and how to debug your programs using the GNU debugger (GDB) and Valgrind will also be covered.By the end of this Linux book, you will be able to develop your own system programs for Linux, including daemons, tools, clients, and filters.
