Discussion on Linux, Apache and MySQL

  1. 1. Linux<br /><ul><li>Linux is an operating system.
  2. 2. It was created On August 25, 1991, by a Finn computer science student named LinusTorvalds,
  3. 3. Linux is Free Software.
  4. 4. Linux is not ownedby one company or person.  
  5. 5. The trademark "Linux" is owned by LinusTorvalds.
  6. 6. Companies share research and development costs with their partners and competitors.
  7. 7. Over 1,000 developers, from at least 100 different companies, contribute to every kernel release.
  8. 8. In the past two years alone, over 3,200 developers from 200 companies have contributed to the kernel--which is just one small piece of a Linux distribution.</li></li></ul><li>Linux<br /><ul><li> Linux powers everything from the New York Stock Exchange to mobile phones to supercomputers to wristwatches to consumer devices.
  9. 9. Mobile Internet devices (MIDs). This includes embedded devices such as smartphones and PDAs, as well as netbookdevices.
  10. 10. Thousands of companies and also governments, use Linux for day-to-day use, attracted by the lower licensing, support costs, as well as the OS’s security and flexibility.  
  11. 11. The analyst group IDC has projected Linux will be a $49 billion business by 2011.</li></li></ul><li>
  12. 12. Apache Web Server<br /><ul><li>Often referred to as simply Apache, a public-domain open source Web server developed by a group of 20 volunteer programmers.
  13. 13. The first version of Apache, based on the NCSA httpd Web server, was developed in 1995.
  14. 14. Source code is freely available, anyone can adapt the server for specific needs, and there is a large public library of Apache add-ons. </li></ul> <br /><ul><li>Apache is similar to development of the Linux operating system.</li></ul> <br /><ul><li>The original version of Apache was written for UNIX, but there are now versions that run under OS/2, Windows and other platforms.</li></ul> <br /><ul><li>The name is a tribute to the Native American Apache Indian tribe, a tribe well known for its endurance and skill in warfare.
  15. 15. Runs on Windows NT/9x, Netware 5.x and above, OS/2, and most versions of Unix, as well as several other operating systems</li></li></ul><li>Apache Web Server<br />Features:<br /><ul><li>DBM databases for authentication
  16. 16. Customized responses to errors and problems
  17. 17. Unlimited flexible URL rewriting and aliasing
  18. 18. Virtual Hosts
  19. 19. Apache is run on over 110 million Internet servers (as of April 2010) (Source, Netcraft).
  20. 20. There is no official support for Apache. None of the developers want to be swamped by a flood of trivial questions that can be resolved elsewhere. </li></li></ul><li>MySQL<br /><ul><li> The official way to pronounce “MySQL” is “My EssQue Ell” (not “my sequel”).
  21. 21. The SQL part of “MySQL” stands for “Structured Query Language.”
  22. 22. SQL was specially designed for database access.
  23. 23. Many databases support the use of SQL to access their data.</li></ul>MySQLand PostgreSQL are two examples. <br /><ul><li>MySQL, is developed, distributed, and supported by Oracle Corporation.
  24. 24. Commonly used by programs that run on websites</li></li></ul><li>MySQL<br /><ul><li>If you use a blogging or CMS software (like WordPress, Drupal or Expression Engine), you will need to place your website on a web host that provides you with a MySQL database. The database will be used by the software to store all your posts (articles), web pages and visitors' comments.
  25. 25. You don't need to learn SQL or learn how to use MySQL, even if you're setting up a blog.
  26. 26. All you need to learn is how to use that particular software (eg, WordPress).
  27. 27. The MySQL Web site (http://www.mysql.com/)
  28. 28. MySQLsoftware is Open Source.
  29. 29. The MySQL software uses the GPL (GNU General Public License),</li></ul> Read about the do’s and don’ts @ http://www.fsf.org/licenses/<br /> <br />
