Win2003 Server build a graphical tutorial on DNS server configuration (more details) _dns server

First, install DNS

1. Install DNS: Start-Control Panel-Add or Remove Programs-add or remove Windows components, and the following window appears:

2. Scroll down, click "Network Services" by clicking "Details", and the following window appears:

3. Check "Domain Name System (DNS)", click "OK"

4. Then return to the "first" picture, click "Next" to start installation;

Second, configure DNS

1. Select Start-Program-Administrative Tools-dns, open the DNS Server Configuration window: First new forward lookup zone, in the Forward lookup zone, click on "Right"-select "New Zone", the New Zone Wizard appears, click "Next"

2. Select Main Area (default is main area), click "Next"

3. Enter the name of the zone: for example, lianghu.com, click Next

4. The system will automatically create a zone file name: Lianghu.coom.dns, select the default can be, click "Next"

5. Select the default "Do not allow dynamic Update", click "Next"

6. Click "Finish" to create the area.

Three. New reverse Zone

1. Click "Right" on the reverse lookup zone-select "New Zone", the New Area Wizard appears, and click "Next"

2. Select the main area and click "Next"

3. Enter the network ID inside id:192.168.1, click "Next"

4. The system automatically creates the zone file name

5. Choose default not to allow dynamic updates

6. Complete the new reverse zone

Four. New host

1. Right-click on the new Area rongsen.com.cn, select "New Host", and the following dialog box appears, enter a name in the dialog box: www

IP Address: 192.168.1.100, click "Add Host", tick "create related pointer (PTR) record", click "Finish", end the creation of the host.

Five. To verify that the DNS server is successfully created

Start-run-cmd:nslookup

Input: www.rongsen.com.cn to see if the resolution is successful.

This completes the creation of the DNS server.

Note: 1, you can use an IP, corresponding to multiple virtual host, above we have only built a virtual host, you can add, for example:

mail.rongsen.com.cn,blog.rongsen.com.cn, wait.

2. Understand what is SOA record, NS record, a record, CNAME, PTR record, MX record

SOA: Host responsible for this domain (not specifically) NS: The host name of the server responsible for resolving this domain, a record (forward resolution): The mapping of host name to IP address (www.rongsen.com.cn-----192.168.1.100), CNAME: An alias to the hostname that accesses the alias just like the host name; PTR record: Is the reverse parsing (IP address to host name Mapping),

The MX (mail exchanger) record is a mail exchange record that points to a mail server. When a user sends a message, the SMTP send server locates the recipient's mail server based on the addressee's domain name (the mailbox address suffix). For example, when a user on the internet wants to send a letter to a user, the user's mail system finds an MX record of the domain name through DNS, and if the MX record exists, the sender's mail server eventually sends the message to the mail server specified by the MX record (yourdomain.com). Conversely, the recipient can not find the server to return the letter.

3, main area, auxiliary area, stub area

A secondary zone is modeled on a primary zone, replicating a replica area that is the same and can provide resolution services for DNS clients, with only one primary zone, but we can create multiple secondary zones for this primary zone.

A stub zone is a copy of a zone that contains only those resource records that are required to identify the authoritative domain Name System (DNS) servers for that zone. Stub zones are used to resolve names between separate DNS namespaces. This type of parsing may be necessary if a corporate consolidator requires that the DNS servers of two separate DNS namespaces resolve the names of the clients in the two namespaces.

The stub zone consists of the following parts:

The initiating authority (SOA) resource record, name server (NS) resource record, and glue A resource record for the delegated zone.

The IP address of one or more primary servers that can be used to update the stub zone.

The primary server for a stub zone is one or more DNS servers authoritative for the child zone, and typically the DNS server hosts the primary area of the delegated domain name.

Implementation of other related service address records:
In addition to the WWW service, the initial example of this article is the FTP and mail services. There are two ways to continue adding additional services:
Method One: In the Left tree directory right click on the newly built primary domain name rongsen.com.cn, select "New Alias (CNAME)", as shown in the following image, in the "Alias" field, enter mail, FTP and other service names , enter www.rongsen.com.cn in the full qualified domain name of the target host. This method is intended to share the 192.168.0.2 IP address with the WWW service for other related services.

Method Two is to set up different IP address points for each service, as is the case in the first example of this article. In accordance with the establishment of the WWW service steps, and then enter the corresponding IP address on the line. As shown in the following illustration, the Mail service is created in an alias manner, and the FTP service is built as a "new host" as the WWW service is established.

Third, the reverse lookup implementation.

That is, the conversion of IP address to domain name is implemented. The basic establishment step is similar to the forward lookup, when the window shown in the following illustration appears, the "Network ID" column is to enter the server network segment to establish a reverse lookup, this example is 192.168.0.X. The other steps are completed as described above. In the tree directory on the left side of the admin interface, you can see the "0.168.192.in-addr.arpa.dns" area file name in the reverse Lookup zone column. Then right click on the name "new Pointer (PTR)". In the window shown below, "host IP number" is the last one of the IP address, such as the WWW service IP address In this example, the last one is 2; the "Host name" column clicks "Browse" to select the host record established in the forward lookup zone Www.rongsen.com.cn ", point OK. By the establishment of the reverse zone name, simply speaking in the browser input 192.168.0.2 can also reach the www.rongsen.com.cn.

The last hint: please remember, the DNS server only provides domain name and IP address mapping work, and that domain name exactly what to do, is by its corresponding IP address bound by the relevant server (such as FTP, e-mail, etc.) to decide. For example, we installed the e-mail server in the example above and specified its IP address pointing to "192.168.0.3". If we are in the DNS server together with other related services of the domain name such as ftp.rongsen.com.cn to this IP address, that is, we do not use this IP address or any of these three domain name can access to this e-mail server!

In addition, the DNS process based on the LAN is described above. If we want to establish DNS mapping records of domain names on the Internet, all domain names that are configured on the DNS server are registered legal domain names on the internet and have a fixed public network IP address. As long as these two conditions are met, the other steps are the same as those in the LAN.

--> --> RAID Features:

RAID0, Raid1/10,riad3,raid5,combine,clearraid

(currently on the market, the most powerful RAID 4 disk bit, Usb2.0+esata array storage System):

The 1348RUS provides with 2 methods to change mode (but two methods you must a pull into clear mode then your can change ):

Note: RAID mode switching has an anti-stop feature, please turn the power off before switching to clear RAID mode, and then press the reset button to turn the power on!

1,you can switch the 3dips in the back of the machine;
You can use the RAID mode switch on the back of the machine for RAID mode switching!

2,you can use the "HDD manage to" change "mode"
You can also use the HDD manage software for RAID mode switching!
(HDD management software please ask customer service!) )

Clear RAID

The computer can crawl four hard drives at the same time, a single hard disk support 2TB (2000g) A total of 8TB, that is, this mode, and the ordinary hard disk box, you can see in the computer four letter! The hard drive cartridge does not use any RAID mode under clear RAID settings. In this state, the 4-block hard disk mode in the hard drive box is independent of the state, in the system is also recognized as 4 separate hard drives, users can choose to store the files of the hard disk. If one of the hard drives is damaged, the data on the other hard drive is not disturbed.

Note: Equivalent to the ordinary hard disk box mode, while you can use a USB or eSATA think two hard drives, if with eSATA, computer host must support the PM (port doubling) function, if not supported, please purchase a eSATA expansion card, General Syba original eSATA expansion cards are supported! (Cannot use the bezel)

Fast mode (that is, RAID 0)

The fast state is also our familiar RAID 0 mode. In the RAID 0 state, the storage data is divided into two parts, stored on two hard drives, the theoretical storage speed of the hard drive is twice times the single hard disk, the actual capacity is equal to two of the size of the smaller hard disk twice times the capacity. The disadvantage of RAID 0 is that any one hard drive fails and the data on the entire raid is not recoverable.

Note: Copy HD movie is more suitable

RAID 1

Safe mode is RAID 1 mode, in which two hard disks mirror each other. The actual capacity of a removable hard disk is equal to the capacity of a smaller hard disk, and the storage speed is the same as a single hard disk. The advantage of RAID 1 is that any piece of hard drive fails, the data stored is not lost, the disadvantage is that the hard disk capacity loss is greater.

Remark: Very important information, such as database, personal data, is foolproof storage solution

RAID 3

RAID-3 requires a minimum of 3 hard drives, one of which is used to store error-correcting data. When a hard drive fails, the lost data can be obtained from the remaining disk data and error correction data in some sort of allocation algorithm. Because RAID-3 the data across the hard drive, the reading speed is not bad, but the write is a bit slow.

RAID 5

RAID-5 spreads raw data and error-correcting data to all hard drives (at least 3). In the RAID-5 system, because the data is written across all the hard drives, this means that the read and write actions may occur simultaneously on the same hard drive. Using only 1/3 of the disk space to store redundant data, RAID-5 offers a good price/performance ratio.

RAID 10

RAID 10 is executed as a striped array, and its segment is a RAID 1 array raid 10 fault tolerance and RAID 1 the same stripe uses RAID 1 segments to get higher I/O rates in this case, RAID 10 can withstand simultaneous errors on multiple disks. Disadvantage: expensive/costly all storage must be installed in parallel in a specific way
Inherently high value, but with very limited measurable

Note:
It is ideal for database servers that require high performance and fault tolerance.

COMBINE

In this mode, four hard drives will be simply bundled together into a hard disk, the performance and read and write speed of the hard disk is the same as a single hard disk, the total capacity of the mobile hard disk is equal to four hard disk capacity of the sum. When the data is written, the system specifies that the data is stored from the first disk, and the data is stored in the first disk after the storage space has been exhausted, and then from the disk that follows. If the data on the first disk is corrupted, the data for the four hard drives will be completely lost.

Above six kinds of RAID mode, everybody burns a friend, can choose according to own circumstance, note the following matters:

1, before use, please keep the data on the hard disk, once the RAID set or change RAID mode, will be cleared all the data on the original hard drive, and asked you to reformat the hard drive, and will not be restored!

2,RAID1 function is mainly suitable for important data backup is not suitable for the use of handcuffs, unable to use two hard drives to set up raid, we recommend using the same brand, model and size of the hard drive to ensure stability and performance, in general, please do not arbitrarily replace or remove the hard drive to avoid loss of data

3, it is recommended to adopt a new hard drive, if the old hard drive used in RAID mode, please complete the action to clear, so that the hard drive back to the factory state, so as not to establish RAID mode failed

4, when using the old hard drive for RAID function, we recommend reformatting the hard drive first (the new hard drive can be omitted)

In 5,raid0/big mode, when one of the hard drives is damaged, all data on the other hard drives will be lost.

6, when replacing RAID mode, RAID mode switch has the anti-stop function, in the RAID mode switch, please turn off the power, and then switch to clear RAID mode, and then press the Reset button, and then turn on the power! Repeat the operation to switch to the RAID mode you want (note that the mode switching data will be cleared)

7,RAID1 (SAFE) mode, will be the first hard disk reconstruction, this is the normal image, will require a certain amount of time, generally 100GB about 1 hours (depending on the environment)

8, the first use or replacement of RAID mode, the power will be turned on the hard drive files will be removed, please back up your information before

9, verify that your hard drive supports RAID capabilities and that Western Digital Desktop Edition is currently known to not support RAID capabilities

10, if you are required to four hard disk data collation, and in handcuffs, we recommend that you use the Clear RAID feature

--> -->Although now has entered the 2008 64-bit era, due to some software reasons, have to install 2003! Some strange raid card on the inside of a U disk to install the driver, but not 2003, you must use the floppy drive to install, recently encountered, the company's internal test server, CPU i7 is very new, in order to save costs to turn out a sil3114raid card, do RAID1, Install win2003 before installation Pray SP2 disk do not recognize raid, do not recognize, a look at the motherboard even the floppy drive slots are gone, think of two programs,

1, the Riad driver to install the image of the trouble to do a second plan

2, using Ghost, now PE strong? A href= "http://www.rongsen.com.cn" target= "_blank" class= "Keylink" >. negative lameness  armed 膔 aid equipment are integrated, steps:

1, the first hard disk inserted in the onboard SATA Port installation System

2, the system installs completes, installs the drive, the most important is to put the Riad drive to install

3, the installation of a good drive system to do a ghost mirror

4. Component raid

5, PE boot, a new point win2003 PE almost all RAID devices are supported

6. Ghost in PE

7, restart everything OK
