17101065 BAB II LANDASAN TEORI 2.1. Centos Linux Centos LAPORAN KERJA PRAKTIK BAB II BAB II LANDASAN TEORI 2.1. CentOS Linux CentOS (Community Enterprise Operating System) merupakan salah satu distro linux yang dikembangkan dari source code Red Hat Enterprise (RHEL). CentOS adalah sistem operasi yang cocok digunakan dalam skala enterprise atau skala perusahaan secara bebas biaya atau open source. Tujuan pengembangan awal sistem operasi CentOS yaitu untuk menyediakan platfrom komputasi skala perusahaan secara gratis dengan mempertahankan 100% kompabilitas terhadap Red Hat Linux atau CentOS dapat dikatakan sebagai kloningan dari RHEL. RHL (Red Hat Linux) Awalannya disebut sebagai Red Hat Commercial Linux yang merupakan distro linux pertama yang memakai system RPM Package Manager, selanjutnya diikuti sebagian perusahaan lain, seperti Mandriva Linux serta SUSE Linux. [4] Pengembangan CentOS dimulai pada tahun 1993 oleh Bob Young dengan membangun ACC Corporation (perusahaan penjual aksesoris software Linux dan UNIX). Pada tahun 1994 Marc Ewing meluncurkan sistem operasi Red Hat Linux hingga akhirnya diakui sisi oleh Bob Young menjadi Red Hat Software, dengan young menjabat sebagai CEO. [4] 2.2.Freeradius Freeradius adalah layanan server yang dapat menggantikan peran router mikrotik dalam melakukan AAA (Authentication, Authorization , Accounting) berdasarkan database yang tersimpan pada server. Freeradius didesain untuk menangani database dalam skala besar sehingga dari segi performa jauh lebih baik dalam melakukan proses AAA (Authentication, Authorization, Accounting). [2] [3] Freeradius didirikan pada Juni 1999 oleh Miquel van Smoorenburg and Alan DeKok dengan rilisan pertama source code “alpha” pada Agustus 1999. Untuk update versi terakhir dari freeradius saat ini yaitu freeradius version 3. [2] Prodi S1TT-IT TELKOM Purwokerto 7 17101065 LAPORAN KERJA PRAKTIK BAB II 2.3.Daloradius Daloradius adalah sebuah platfrom web yang digunaan untuk mengelola server RADIUS yang ditulis menggunakan bahasa pemrograman PHP dan Java Script. Daloradius dapat melakukan manajemen pengguan, group, profile, accounting, billing, dan terintegrasi dengan google maps untuk menentukan geo lokasi. Menurut keterangan dari website resminya, daloradius dapat mengguakan berbagai jenis database system seperti MySQL, PostgreSQL, Sqlite, MsSQL dan lainnya. [5] 2.4.PHP PHP merupakan singkatan dari Hypertext Pre-processor, yang sebelumnya disebut Personal Home Pages yang pertama kali dibuat oleh Rasmus Lerdorf pada tahun 1995. [6] PHP merupakan bahasa pemrograman script server-side yang digunakan secara luas untuk penanganan pembuatan dan pengembangan sebuah situs web dan bisa digunakan bersamaan dengan HTML Bahasa pemrograman PHP dapat digunakan untuk membuah website dinamis, dapat digunakan untuk menyimpanj data ke dalam database, membuat halaman yang dapat berubah-ubah sesuai dengan input user, memproses form, dll. File Bahasa pemrograman PHP memiliki format file .php. [7] Bahsa pemrograman dengan tipe script server-side adalah bahas pemrograman yang script atau syntaxnya diolah atau dieksekusi dibagian server bukan browser. Untuk menjalankan program PHP memerlukan aplikasi tambahan disisi server yaitu paket php dan xampp disisi end sistem operasi desktop. Kelebihan dari program script server-side tidak terbaca pada saat inspect element pada browser, sehingga program tidak mudah diduplikasi. [8] 2.5.MariaDB MariaDB merupakan sistem manajemen database relasional yang dikembangkan dari MySQL. MariaDB dikembangkan oleh komunikas yang sebelumnya berkontribusi dalam pengembangan mysql. Maka dari itu MariaDB dapat dikatakan versi lain dari mysql denga isi yang sama. Tujuan pengembang mysql membangun MariaDB yaitu dikarenakan mysql sudah Prodi S1TT-IT TELKOM Purwokerto 8 17101065 LAPORAN KERJA PRAKTIK BAB II diakui sisi oleh orecel sehingga mysql saat ini memiliki lisensi proprietary. Selain itu, dengan diakui sisinya mysql oleh oracle menyebabkan pengembang tidak bisa leluasa dalam mengembangkan MySql. [9] [8] Pengembangan MariaDB dipimpin oleh Michael "Monty" Widenius, salah satu founder MySQL AB dan Monty ProgramAB. Penamaan MariaDB menggunakan salah satu anaknya Maria. Tak beda jauh dengan MySQL, MySQL juga dinamai dengan salah satu nama anakya yaitu My. MariaDB tetap mempertahankan kompabilitas dan API seperti yang dimiliki oleh MySq, jika pada MySql terdapat InnoDB maka MariaDB memiliki XtraDB yang menjadi mesin penyimpanannya. [9] [7] 2.6.Apache Web server Apache adalah software web server yang gratis dan bersifat open source. Nama resmi dari pengelola software ini yaitu Apache HTTP Server, Apache dikembangkan oleh Apache Software Foundation. Apache adalah situs web server tertua yang dirilis versi pertamanya pada tahun 1995. Tujuan lain dari pengembangan Apache adalah menyediakan web server yang aman, efisien, dan dapat dikembangkan dengan mudah. [10] Web server merupakan perangkat lunak yang merespon permintaan (request) dari browser. Jadi, web server mempunyai peran untuk menghubungkan antara user dengan server website. Dalam beberapa contoh peran web server yaitu misal, jika user ingin megakses suatu web melalui browser dan browser akan mengirimkan request pada web server, kemudia web server akan mencari data yang direquest user, kemudian web server akan mengirimkan HTTP response ke browser dan mengubahnya menjadi halaman website.

Two months later, on August 25, Linus Torvalds announced Casting the Net (1995), and The his new operating system on comp.os.minix. Today, Android, Google’s Daemon, the Gnu and the Penguin I (2008). [email protected] version of Linux, is used on over two billion smartphones and other appli- ances. In this article, I provide some history about the early years of Linux. Linus was born into the Swedish minority of Finland (about 5% of the five million Finns). He was a “math guy” throughout his schooling. Early on, he “inherited” a Commodore VIC- 20 (released in June 1980) from his grandfather; in 1987 he spent his savings on a Sinclair QL (released in January 1984, the “Quantum Leap,” with a Motorola 68008 running at 7.5 MHz and 128 kB of RAM, was intended for small businesses and the serious hobbyist). It ran Q-DOS, and it was what got Linus involved: One of the things I hated about the QL was that it had a read-only operating system. You couldn’t change things ... I bought a new assembler ... and an editor.... Both ... worked fine, but they were on the microdrives and couldn’t be put on the EEPROM. So I wrote my own editor and assembler and used them for all my programming. Both were written in assembly language, which is incredibly stupid by today’s standards.

  • The Center for the Public Domain: a Short-Lived Venture Philanthropy
    Center for Strategic Philanthropy and Civil Society Teaching Case Revised: January 18, 2007 The Center for the Public Domain: A Short-Lived Venture Philanthropy “If we could find a champion for whatever initiative it was that we wanted to support, then, because we were much more lithe and less cumbersome than some big organizations, we could invest in that champion. If we found a startup, we started it. If we found a supporter, we supported it. My strength was in finding the champion, and Bob’s 1 strength was in trusting me that I was right.” —Laurie Racine, president of the Center for the Public Domain RED HAT, INC. Bob Young A native of Ancaster, Ontario, Canada, Robert “Bob” Young earned a degree in history from the University of Toronto in 1976. While in college, he encountered the work of the seventeenth- century Scottish philosopher Adam Smith. In a 2007 interview, Young outlined how Smith’s thinking had influenced his own: Going back to university days, I’ve greatly admired Adam Smith, because he was able to articulate the value in a free-market democracy of what entrepreneurial businessmen actually did. In a free-market democracy, the citizen and the consumer are the same person. You can solve problems by marching on Washington—or, in Adam Smith’s day, by marching on Whitehall—or you can solve the same problem in the marketplace. Given that the private sector accounts for eighty percent of our economy, successful businessmen arguably have every bit as much influence on our society as George Bush or Bill Clinton has.

However, the hardware management and kernel framework (GNU HURD) was largely incomplete. ● In 1991, Linus Torvalds released the first version of the Linux kernel after being frustrated with the restrictions imposed by the MINIX operating system license. In part because he wanted to learn about building an operating system on IBM PCs, he used the MINIX environment to build the first kernel, and then replaced the MINIX components with GNU ones to put together a functional system for development. ● Within a year, it was quickly discovered that having to pull components and assembling them manually was unsustainable to make a Linux-based environment useful. 4 Thus, the first distributions arrived... ● The Softlanding Linux System (SLS) was the first, released in 1992. It provided a comprehensive collection of software to make a usable Linux system. The only other thing to note was that it was quite buggy and difficult to set up.
