Description
Technical Field
The present disclosure relates to the field of big data, and in particular, to a method and an apparatus for modifying an IP address of a big data cluster host.
Background
Large data Cluster (Cluster) generally refers to a collection of multiple servers together providing the same service, appearing to a client as if there is only one server. A big data cluster may also be referred to as a server cluster, and the servers belonging to the big data cluster may be referred to as nodes, node servers, or hosts.
For a big data cluster all-in-one machine, after the all-in-one machine is oriented to a client, the network environment initialized by the all-in-one machine product conflicts with the network environment of the client, or when the client needs to perform network redeployment and migration of a big data cluster, the IP address of a node in the big data cluster needs to be modified. In the prior art, an IP address in a related configuration file in a host is manually modified, the modified IP address is stored, and a network service is restarted through a service network restart; aiming at the IP address in each service configuration of the Hadoop ecological circle, a user can only modify the configuration file of the related service manually.
When the number of the host nodes is small or the number of the service configuration files of the Hadoop ecological circle is small, and when the number of the host nodes is large or the number of the service configuration files is large, the manual modification project is huge, and the actual working efficiency is influenced.
Therefore, scripts are used in the related art to modify host IP addresses in batches. However, after the script is used to modify the IP address of the host, although the IP of the surface layer is indeed modified, the configuration items depending on the IP of each node in the configuration file of the relevant Hadoop service in the node are not modified, so that the big data cluster does not monitor the relevant service components. The user also needs to compare each configuration file of each service deployed in the node, and if there is a configuration item for setting the IP, the user needs to manually modify and store the configuration items.

Fig. 1 shows a flowchart of a large data cluster host IP address modification method according to an embodiment of the present disclosure, which may be applied to a host node in a large data cluster, which may be any host in the large data cluster.
Fig. 2a shows a schematic diagram of a big data cluster according to an embodiment of the present disclosure, and fig. 2b shows a timing diagram of a big data cluster host IP address modification method according to an embodiment of the present disclosure.
As shown in fig. 1, the method includes:
step S11, receiving an IP configuration file sent by the management node, where the IP configuration file includes one or more IP address pairs, and each IP address pair includes a first IP address and a corresponding second IP address.
The first IP address may be an Old host IP address, the second IP address may be a New host IP address, and the first IP address and the corresponding second IP address are recorded in an IP configuration file in the form of an IP address pair (e.g., < Old host IP, New host IP >), as shown in table 1.
As shown in fig. 2b, first, an IP configuration file is obtained, for example, when the big data cluster faces a user, if a network environment of the user is different from a network environment of the big data cluster, an IP address conflict may exist, and the IP addresses of the hosts of the big data cluster need to be modified, which hosts have IP addresses in conflict may be detected based on an IP conflict detection tool, and a new IP address may be reconfigured for the hosts having IP address conflict. The IP configuration file may be stored in a big data cluster configuration installation package on a management node, the management node may be deployed in any host node in a big data cluster, and a big data cluster management client, a cluster management tool, and the like may be installed on the host node. The IP configuration file may also be stored in other suitable locations, for example, a system file, etc., which is not limited in this disclosure.
In a possible implementation manner, the management node may automatically read a local IP configuration file by running a script program, write the local IP configuration file into a temporary file, and send the IP configuration file to each host node, where the host node may receive the IP configuration file sent by the management node.
TABLE 1IP CONFIGURATION FILES
| Serial number | Old host IP address | New host IP address |
| 1 | Oip1 | Nip1 |
| 2 | Oip2 | Nip2 |
| 3 | Oip3 | Nip3 |
| 4 | Oip4 | Nip4 |
| … | … | … |
In one possible implementation, as shown in fig. 2b, all the services of the big data cluster may also be turned off before step S11, so as not to affect the services during the IP modification.
And step S12, determining a new IP address corresponding to the local host IP address according to the local host IP address and the IP configuration file, and modifying the local host IP address into the new IP address.
In one possible embodiment, the above process may be performed by running a script in the host node to implement large data cluster host IP address modification, as shown in fig. 2 b. In the running process of the script, the IP address of the local host can be determined, then the IP configuration file is automatically read, the IP address pair is inquired in the IP configuration file, after the first IP address (old IP address) which is the same as the IP address of the local host is found, the new IP address (second IP address) corresponding to the IP address of the local host is determined, and then the IP address of the local host is modified into the second IP address.
In one example, modifying the local host IP address to a new IP address may be accomplished by modifying an IP address in a local system configuration file to the new IP address.
As shown in table 1, the IP configuration file may include one or more IP address pairs, and the script may be read item by item, taking host 1 as an example, the IP address of host 1 may be determined first, then the IP address of host 1 is queried in the first IP address in the IP configuration file, and the IP address in the system configuration file of host 1 is modified to a new IP address, for example, the old IP address in the network card configuration file/etc/syscon/network-scripts/ifcfg-eth 0 and the old IP address in the/etc/hosts file may be modified to a new IP address. For example, as shown in table 1 and fig. 2a, the old host IP address is found to be Oip1 according to the IP address of the host 1, so that the new IP address corresponding to the local host IP address can be determined to be Nip1, and the old IP address in the network card configuration file/etc/sysconfig/network-scripts/ifcfg-eth 0 and the old IP address Oip1 in the/etc/hosts file of the host 1 are modified to be Nip 1.
In one possible implementation, after the IP address modification of the host system profile is completed, the host 1 may also restart the network service to validate the modified new IP address.
Step S13, modifying the first IP address configured by all local service components into a corresponding second IP address according to the modification instruction sent by the management node and the IP configuration file.
For example, the host node may include one or more service components thereon, such as various service components of a Hadoop ecosystem. Each service component is configured with a corresponding IP address, and the host node can acquire corresponding services through the IP addresses configured by the service components. In step S12, the IP address of the host node has been modified, and if the IP address configured by the service component is not modified, the corresponding service may not be obtained, and the service fails.
Those skilled in the art will appreciate that the service profile may also be a profile of other distributed computing framework related services, such as Storm, Spark, etc., and the disclosure is not limited thereto.
The management node may send a modification instruction to all host nodes, and after receiving the modification instruction, the host node may modify the IP address configured by the local service component according to the IP configuration file.
In a possible implementation manner, modifying the first IP address configured by all local service components to the corresponding second IP address may include: and modifying the first IP address in the service configuration file corresponding to all the local service components into a corresponding second IP address. Each service component is configured with one or more corresponding service profiles, and modifying the IP address of the service component configuration can replace the old IP address in the corresponding one or more service profiles with the new IP address. For example, the host node may modify the IP address by running a script, the script reads the service configuration files configured by each service component one by one, and when the IP address is read, the corresponding first IP address may be searched in the IP configuration file, and the first IP address in the service configuration file is modified to the second IP address corresponding to the first IP address in the IP configuration file until all the service configuration files are modified.
The host node modifies the local host IP address by receiving the IP configuration file sent by the management node, and modifies the IP addresses configured by all local service components according to the modification instruction sent by the management node. According to the method for modifying the IP address of the host of the big data cluster, the modification of the IP address of the host and the IP address in the service configuration file can be automatically completed in batches, the efficiency and the usability of the big data cluster deployment are improved, and the method is more flexible.
When the method is user-oriented, when a user needs to execute operations related to IP modification, if large-scale IP modification such as cluster migration is involved, the operation of modifying the IP address is automatically executed through the script, so that the working time is greatly reduced, and the working efficiency and accuracy are greatly improved.
Fig. 3 shows a flowchart of a big data cluster host IP address modification method according to an embodiment of the present disclosure, and as shown in fig. 3, in one possible implementation, the method may further include:
step S14, responding to the service component inquiry command sent by the management node, and sending local service component configuration information to the management node;
and step S15, receiving the modification instruction sent by the management node.
In a possible implementation manner, the management node may further send a service component query instruction to each host node, and after receiving the query instruction, each host node may query local service component configuration information, for example, which service components are configured locally, which service components are configured, which service configuration files are configured for the configured service components, and the like. The host node may send the queried local service component configuration information to the management node in response to the query instruction. For example, host 1 queries that service component a and service component B are locally configured, service component a is configured with service profiles a1 and a2, service component B is configured with service profiles B1 and B2, and host 1 may send the type of service component and/or the corresponding service profiles a1, a2, B1, and B2 to the management node; host 2 queries that no service components are locally configured and may return an empty message to the management node.
After receiving the service component configuration information sent by the host node, the management node determines that the host 1 is configured with the service component and the host 2 is not configured with the service component according to the service component configuration information, and the management node 1 may send a modification instruction only to the host node configured with the service component.
The host node that receives the modification instruction sent by the management node may modify the old IP address in the service configuration file configured by all local service components to the corresponding new IP address according to the IP configuration file, as described in step S13, which is not described again.
And sending local service component configuration information to the management node according to the query instruction sent by the management node, so that the management node selectively sends a modification instruction according to the configuration condition of each node service component, the system overhead is reduced, and the system performance is improved.
Fig. 4 shows a schematic diagram of an application of a big data cluster host IP address modification method according to another embodiment of the present disclosure. In one possible implementation, as shown in FIG. 2a, the big data cluster includes a management interface that includes controls to run scripts.
For example, as shown in fig. 2a and fig. 4, the modification of the IP address of the big data cluster may be completed through a management interface, and an entry or a control for modifying the IP address is displayed on the management interface. The IP configuration information can be obtained through an interactive interface provided by a management interface of the browser side, wherein the IP configuration information can comprise one or more new and old IP address pairs. After the IP configuration information is obtained, the modification of the IP address of the big data cluster can be realized by clicking an entrance or a control for modifying the IP address on the management interface.
The script is visualized on the management interface, so that the operation is convenient, and the usability is improved.
