IT operation and maintenance is very important for many enterprises. Next, some basic knowledge of operation and maintenance, Long Shaowen, director of IT operation and maintenance every day, introduces you to the basic knowledge of IT operation and maintenance.
The basic knowledge of IT operation and maintenance management, Microsoft system
The acquaintance of Windows is the most basic. Of course, as a maintenance manager, not all day to play a Windows7 or XP can cross the. You have to master the Microsoft Active
Directory and its top layers of various services and use of the building. Commonly used are ISA, Exchange, SQL Server. With Windows
2008, Hyper-V became a heavy weapon that Microsoft engineers had to master.
IT operation and maintenance management basic knowledge two, Linux/BSD system
Although Ubuntu is very hot today, most of the companies use the Redhat series and the Suse series. You have to know DNS, NIS, Apache, SMB,
These customary services are DHCP, Sendmail, FTP, and MySQL. Assuming that the company's IT business is large to the outside world, you have to learn about LVS or Nginx load balancing technology.
Friendship tip: imagine that you are going to renren.com or watercress and other cutting-edge Web2.0, so you have to know Cassandra, mixed type non contact database; distributed memory object caching system for Memcache high power (like it by maintaining a consistent large Hash table to store data in various formats in memory Li).
Now that we have talked about Linux, BSD is also a favorite of open source. BSD's safety and efficiency are very impressive. Now many companies including Yahoo and Sina use it to run. After this kind of system is familiar, it will also reduce the degree of difficulty (the same Unix lineage) in Solaris.
If the middleware is required, the Weblogic (Oracle system) or the WebSphere (IBM system) and the Jboss (red hat system) can be properly contacted. These things are very common in the large use that is now in vogue.
IT operation and maintenance management basic knowledge three, programming development
Learn the Powershell of the Windows system. If you have to look at VBscript in the last few years, it will be the world of Powershell in the future.
PowerShell was officially unveiled by the Microsoft Corp in the fourth quarter of 2006. It makes Windows close to Unix in operation and maintenance.
The interval of the operating system such as Linux. .Net Framework 2 is now supported. It can run in XP
SP2 after a variety of operating systems. It can also support the existing Windows maintenance models such as WMI, COM, ADO.NET, ADSI and so on. This new technology provides rich control and self - control
The dynamic system Vee Snagan; and "scripting speech" (scripting
Languages) is a computer language used to write order. Scripting language is usually easy, easy to learn and easy to use. The purpose is to expect people (developers) to write sequential writing at high speed.
As for the operation and maintenance personnel under the Linux platform, the combination of the Shell plus Perl, after all, has passed for many years. This combination is constantly working for engineers at large sites. another
In addition, Python is also a very useful tool. This kind of speech has very simple and clear grammatical features, which is suitable for the completion of various high-level posts, and can run in almost all operating systems. Now, based on
The related technology of this language is growing rapidly, the number of users is expanding rapidly, and the resources are very much.
The basic knowledge of IT operation and maintenance management four.
It is necessary to know the knowledge of the network root, the network communication protocol and the multiple network equipment. It is suggested that the products of CISCO and HUAWEI are familiar.
Friendship hints: many people think of HUAWEI and H3C as one, and their two orders are not compatible.
That is in a slightly bigger, perhaps you are in the IDC task. It must also learn to mix, implementation plan, and complete the test debugging of enterprise LAN and WAN, VLAN is required. The other is network services such as video, voice, and so on.
At the end of the day, all of them wanted to improve their peers to learn about CCNP or H3CNE.
IT operation and maintenance management basic knowledge five, storage
Here is a brief introduction to the notions of the rookie. Of course, such things are often used in enterprises with large amounts of data.
First, say SAN. SAN is a network that is dedicated to providing storage and backup maintenance for business data or operator data. Because of the network based storage, SAN has a greater capacity and stronger function than the traditional storage technology.
A dedicated storage and maintenance software can be installed directly on the mainframe, server or other server computers in SAN, which is equipped with hard disk and tape. Nowadays, a large number of SAN are based on fiber channel communication.
The machine and the hub. Equivalent to a high-speed subnet, usually SAN consists of a RAID array of fiber channels, and SAN and server and client data communicate with the SCSI command rather than TCP/IP,
Data processing is a "block level".
NAS takes data as the center, concentrates storage on servers and servers, concentrates on data maintenance, so as to release bandwidth, improve functions, reduce total cost and maintain investment. Its cost is far lower than the use of server storage, but the efficiency is far higher than the latter. This kind of equipment is relatively easy.
