First, what is Linux?
Linux was born in October, 1991, until now already some more than 10 years history. Linux is a set free also function integrity UNIX software. Also it is 32 operating systems, the operation is stable also effectiveness, widely serves as the server operating system. Linux carries on is the open style primitive code (Open Source) the spirit, all Linux Source Code (source code) may free obtain, this causes it relative other operating systems (expensive Windows NT to say the price to be extremely cheap in particular). At the same time, because its source code is open, therefore, may conveniently and unceasingly improves by the global thousands programmer application, caused it to progress by leaps and bounds - -- the present Linux essence in the technical progress already to promote to 2.4 edition. This kind of progress enables Linux to become the operating system which the market doubly favours, in 1999, Linux has surpassed Novell Corporation's Netware, becomes is only inferior to Microsoft Windows NT is listed the second server operating system. IDC forecast that, future four year Linux will produce goods the quantity to the year to grow 28% proportion growth, grows from 1999 1.3 million sets to 2004 4.7 million sets.
At present, global biggest Linux is Red Hat Linux, Red Flag Linux is the Chinese CompTIA 225-030 CompTIA HT0-102 Linux first brand.
Second, why should you choose the Linux authentication?
After China joins WTO, the intellectual property rights protection gradually will be standard, causes more enterprises to change cost inexpensive Linux to operate the platform. Statistics have indicated, in 2000, Linux surpasses 27% in server market CompTIA, its rate of increment surpasses the Windows operating system 4 percentage points. At the same time, this market rapidly is developing, IDC indicated on the other day, Linux rapidly increases the user urgently needed specialist training, to in 2004, the light was in US, this market can grow to 311 million Dollar. Especially Linux continues unceasingly to permeate in each big enterprise, causes Linux the professional education training to be especially critical. Therefore, eagerly changes the IT field to these the schoolmate said that, the linux authentication is a good choice. Looked in at present below that, at least it has the superiority:
Windows the XP soaring price and the promotion charge policy causes more enterprises and individual user changes the free opening the Linux operating system, the goal employer group can rapidly grow;
Conveniently to the potential employer proved you in the Linux aspect unique specialized skill, obtain the opportunity which promotes and raises salaries;
Becomes very few Linux to authenticate engineer, may in with tens of thousands of MCSE, in the CCNA competition blooming, with ease wins;
Relative other IT authenticates a more inexpensive expenditure (for example widely LPIL which accepts Linux authentication two to take a test each only to need 100 US dollars).
At the same time, according to the Tech RePublic investigation, in the IT field the public figure also has the quite many technical personnel to consider the Linux authentication, this proportion reaches as high as 45%.
Third, international Linux authentication present situation
At present altogether has four kinds in the overseas widespread acknowledgement linux authentication:
1. Linux Professional Institute (abbreviation is LPI)
The degree pays attention which on the present Linux association looked that, the LPI authentication plan has received the most widespread support. LPI already ahead of time has promoted Linux Profession Institute Certified-Level 1 (abbreviation was LPIC-1) authenticates the plan, near future also will be able according to prearrange the plan to promote 2 and the 3rd level of authentication. In order to obtain the LPIC-1 certificate, you must long reach 90 minutes tests through two each one - --101 (LPI General Linux, Part1) and 102 (LPI General Linux, Part 2). LPI LPIC - 1 takes an exam the object mainly to have at least 1 year Linux work CompTIA 225-030 CompTIA HT0-102 experience system manager.
2. Sair Linux and GNU
Is same with LPI, Sair has provided three kind of ranks authentication plans;
Level 1 - Sair Linux & GNU Certified Administrator (LCA)
Level 2 - -- Sair Linux & GNU Certified Engineer (LCE)
Level 3 ---- Master Sair Linux & GNU Certified Engineer (MLCE)
The 1st level is at present obtains the complete development the Sair authentication project, this point is also same with LPI.
3. Linux +
CompTIA the sponsor Linux+ authentication plan is most newly enters Linux to authenticate the market. This plan officially promotes to September 21, 2001, at present already and industry in has aroused the widespread interest in the Linux jobholders. Nearly all main authentication CompTIA have all composed in view of the Linux+ authentication test reference book, the multitudinous IT training center all was preparing the Linux+ authentication to plan.
Other belts promotes which with CompTIA "+" the authentication is same, the Linux ten credentials only need through a test then to obtain (VUE and Prometric test center conduct this kind of test), once you obtained the Linux+ credentials life-long, the certificate have been effective. The Linux+ test price is 190 US dollars, the test uses the multi- selected topics form, when the long 120 minutes, cover the content very are many all is and Sair as well as the LPI authentication completely same, but the difficulty slightly has reduces.
LPI and the Sair authentication plan test object is has the relative experience the Linux network and the system manager, but Linux+ authentication then mainly faces only has individual which half year about the Linux experience, wants to obtain the basic Linux technology qualifications.
4. Red Hat Certified Engineer
Linux+ has represented the preliminary Linux authentication plan, but high-level Linux authentication since long ago then nearly completely is Red Hat Certified Engineer (RHCE) authenticates the plan the world. RHCE is this domain most has the challenge authentication test, therefore it also is the most valuable Linux authentication. But also is most expensive, the complete set curriculum expense is 2, 498 Dollar, also may alone make the authentication examination, the expense is 749 Dollar.
Fourth, domestic Linux authentication
If your goal only is has an achievement in domestic Linux, then your choice only should have: Red Flag Linux. As the Chinese earliest Linux operating system, Red CompTIA 225-030 CompTIA HT0-102 Flag Linux at present every year sold the quantity already to surpass 1, 000, 00.01 million, were in the present China market share biggest Linux, has the widespread user group and the multitudinous training organization. Moreover, Red Flag LinuX includes the national computer application level test module, the national Ministry of Education acknowledged that, take the Chinese Academy of Science, the information industries department technology, the fund as a backing, has safeguarded the authentication system technical gold content and CompTIA, causes it to outshine others in the domestic Linux authentication.
