Description

A kind of ip address management method of server management network card under dhcp network

the

technical field

The invention relates to a management method of a server management network card, in particular to an IP address management method of a server management network card under a dhcp network.

Background technique

At present, a large number of Internet users purchase batch servers, and with the gradual maturity of remote management technology, the management of servers no longer depends on the local management of the computer room where the server is located, but is controlled remotely through the network, so that when the server has operating system failures such as crashes and other problems When the problem occurs, or when the operating system needs to be reinstalled, it can be solved through the management network card remotely, and the management can be performed by directly accessing the ip address of the management network card of the faulty server remotely through the IE browser.

Dhcp: English full name Dynamic Host Configuration Protocol, translated as Dynamic Host Configuration Protocol. dhcp is a local area network network protocol that uses UDP protocol to work. It has two main purposes: to automatically assign IP addresses to internal networks or network service providers, and to users or internal network administrators as a means of central management of all computers.

There are two ways to configure the ip address of the server management network card, one is dhcp, which uses the dhcp server in the network to assign an ip address to the server management network card, and the other is static allocation, which requires manual configuration of the static management network card ip for each server address. In general, in order to reduce the workload, the ip address configuration of a large number of server management network cards uses the dhcp allocation mode. In this way, when a business fails, you can directly access the ip address of the corresponding server management network card to remotely manage the server.

But this way of operating has the following problems:

1. According to the working principle of the dhcp server, after the server management network card logs in to the network for the first time, it will obtain an IP address of the server management network card from the dhcp server, including lease and other information, and the dhcp server will try to let the server management network card use the original one. IP address. However, if the lease is not renewed after the lease expires, this IP address may be occupied by other server hosts, and the dhcp server will not allow this IP address to be used by it, but will obtain a new IP address from the dhcp server. The latest IP address. Therefore, when the lease expires and the server fails and the lease is not renewed, the IP address of the server management network card may change, thereby affecting the management of the server by the client.

2. If there is a large-scale downtime maintenance, the comparison table of the ip address of the business and management network card may change a lot, which means that the comparison table needs to be re-managed and configured. Its continuous update and maintenance itself is a problem, and it cannot be guaranteed to remain unchanged. .

Contents of the invention

The technical task of the present invention is to provide a kind of ip address management of the server management network card under the dhcp network, which has reasonable design, easy operation, fixes the IP address of the server management network card, and realizes that the comparison table of the ip address of the server management network card remains unchanged. method.

Technical task of the present invention is realized in the following manner, under dhcp network environment, carries out the ip address management of server management network card to all managed servers;

Including the following steps:

(1) When the managed server is turned on for the first time, the server management network card uses the dhcp mode to obtain the ip address by default, and at the same time, a comparison table of the mac address of the server management network card - the ip address of the server management network card is generated on the dhcp server;

(2) Use the ipmi command on the managed server to obtain the comparison table of the serial number of the machine - the mac address of the server management network card;

(3) Summarize the comparison table of server host serial number-server management network card mac address-server management network card ip address;

(4) Obtain the comparison table of business-host serial number from the business department; thereby establish a comparison table of business-server host serial number-mac address of server management network card-ip address of server management network card;

(5) There are two ways to configure the dns configuration table:

①. Create a comparison table of the host serial number of the managed server and the ip address of the server management network card into the dns configuration table;

②, or establish a comparison table of the managed server business and the ip address of the server management network card into the dns configuration table;

(6) Configure the dns configuration table using the method ① in step (5), then the client can manage the corresponding server by directly accessing the serial number of the host through the ie browser;

Configure the dns configuration table using the method ② in the step (5), and manage the corresponding server by directly accessing the service name of the server through the ie browser from the client.

The method steps to realize the establishment of the business-server host serial number-the mac address of the server management network card-the ip address of the server management network card to remain unchanged are as follows:

(1), Create a new scope:

①. Open the Microsoft DHCP server management window, right-click the DHCP server;

②. A menu pops up, select the "New Scope" option;

③. The system pops up a wizard dialogue window, and fill in the relevant content step by step according to the wizard; relevant content: such as the IP address that can be used, the IP address that cannot be used, etc.;

④. When filling in the above information, the network administrator enters a "server allocation rate lease period", which is 8 days by default; when creating a new scope, it cannot be specified as unlimited; the scope needs to be established Afterwards, modify this item again;

(2) After the scope is established, modify the service rate lease period allocated by the server:

① After the scope is established, select this scope in the dhcp server management window;

②. Click the right mouse button, select "Properties" in the menu, and find the "dhcp client lease period" option;

③. Select this option as "Unlimited".

We can see that there are two radio boxes "Limited to" and "Unlimited". By default, its option is "Limit to" and its lease period is eight days. Here, in order to achieve the purpose of fixing the IP address of the server management network card, this option is selected as "unlimited"; in this case, there is no such thing as a lease of the IP address of the server management network card; the dhcp server will not take it back actively The server manages the IP address of the network card.

The implementation method steps of fixing the IP address of the server management network card are as follows:

If the motherboard of the managed server fails and needs to be replaced, query the mac address of the management network card of the original server, and then reset the mac address of the management network card of the new server back to the mac address of the management network card of the original server; The ip address of the server management network card acquired by the server management network card from the dhcp server remains unchanged, and will not affect the normal access of the client to the original comparison table.

DNS is the abbreviation of Domain Name System (Domain Name System), which is a core service of the Internet. As a distributed database that can map domain names and IP addresses to each other, it can make it easier for people to access the Internet without having to remember An IP number string that can be read directly by the machine.

The ip address management method of the server management network card under a kind of dhcp network of the present invention has the following advantages:

1. If there is no lease of the IP address of the server management network card, the dhcp server will not actively take back the IP address of the server management network card; the IP address of the server management network card is fixed, which will not affect the client's management of the server;

2. Realize that the comparison table of the ip address of the server management network card remains unchanged, which will not affect the normal access of the client to the original comparison table;

3. The design is reasonable and the operation is simple and convenient, therefore, it has good promotion and use value.

Detailed ways

Referring to the specific embodiments, the ip address management method of the server management network card under the dhcp network of the present invention will be described in detail below.

Obtain the serial number of the host from the server operating system: (the following uses the linux operating system as an example) [rootlocalhost ~]# dmidecode |grep Serial Number

Serial Number: 1234567890 (corresponding to the host serial number in bios).

(3) Summarize the comparison table of server host serial number-server management network card mac address-server management network card ip address;

(4) Obtain the comparison table of business-host serial number from the business department; thereby establish a comparison table of business-server host serial number-mac address of server management network card-ip address of server management network card;

The comparison table of a specific example is shown in the following table:

business host serial number The mac address of the server management network card The ip address of the server management network card web 20120708 00-50-56-C0-00-08 192.168.0.1 oa 20120709 00-50-56-C0-00-09 192.168.0.2 ftp 20120710 00-50-56-C0-00-10 192.168.0.3 db 20120711 00-50-56-C0-00-11 192.168.0.4

Table 1

(5) There are two ways to configure the dns configuration table:

①. Create a comparison table of the host serial number of the managed server and the ip address of the server management network card into the dns configuration table;

②, or establish a comparison table of the managed server business and the ip address of the server management network card into the dns configuration table;

(6) Configure the dns configuration table using the method ① in step (5), then the client can manage the corresponding server by directly accessing the serial number of the host through the ie browser;

Configure the dns configuration table using the method ② in the step (5), and manage the corresponding server by directly accessing the service name of the server through the ie browser from the client.

The method steps to realize the establishment of the business-server host serial number-the mac address of the server management network card-the ip address of the server management network card to remain unchanged are as follows:

(1), Create a new scope:

①. Open the Microsoft DHCP server management window, right-click the DHCP server;

②. A menu pops up, select the "New Scope" option;

③. The system pops up a wizard dialogue window, and fill in the relevant content step by step according to the wizard; relevant content: such as the IP address that can be used, the IP address that cannot be used, etc.;

④. When filling in the above information, the network administrator enters a "server allocation rate lease period", which is 8 days by default; when creating a new scope, it cannot be specified as unlimited; the scope needs to be established Afterwards, modify this item again;

(2) After the scope is established, modify the service rate lease period allocated by the server:

① After the scope is established, select this scope in the dhcp server management window;

②. Click the right mouse button, select "Properties" in the menu, and find the "dhcp client lease period" option;

③. Select this option as "Unlimited".

We can see that there are two radio boxes "Limited to" and "Unlimited". By default, its option is "Limit to" and its lease period is eight days. Here, in order to achieve the purpose of fixing the IP address of the server management network card, this option is selected as "unlimited"; in this case, there is no such thing as a lease of the IP address of the server management network card; the dhcp server will not take it back actively The server manages the IP address of the network card.

The implementation method steps of fixing the IP address of the server management network card are as follows:

If the motherboard of the managed server fails and needs to be replaced, query the mac address of the management network card of the original server, and then reset the mac address of the management network card of the new server back to the mac address of the management network card of the original server; The ip address of the server management network card acquired by the server management network card from the dhcp server remains unchanged, and will not affect the normal access of the client to the original comparison table.
