[ detailed description ] embodiments
For better understanding of the technical solutions in the present specification, the following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only a few embodiments of the present specification, and not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step are within the scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the specification. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In the embodiment of the invention, the activating equipment is connected with the slave equipment to be accessed into the distributed database, the activating equipment automatically installs the slave equipment based on the preset boot file and the operating system installation file, manual configuration is not needed, the workload of equipment deployment personnel is reduced, and the slave equipment deployment speed is accelerated.
Fig. 1 is a flowchart of a distributed database deployment method according to an embodiment of the present invention. The method is applied to an activation device, and as shown in fig. 1, the method comprises the following steps:
In some embodiments, the activating device may assign an IP address to the slave device based on a Dynamic Host Configuration Protocol (DHCP) service.
And 102, allocating an IP address to the slave equipment according to the IP acquisition request. The method includes the steps that an IP pool containing a plurality of IP addresses can be configured in advance, and after an IP acquisition request sent by the slave device is received, an unused IP address is randomly selected from the IP pool and allocated to the slave device.
And 103, sending the IP address and a preset boot file to the slave equipment, wherein the preset boot file is used for installing a boot system on the slave equipment. Since the installation of the operating system can only be performed under the boot system, the preset boot file may be sent to the slave device first, so that the slave device installs the boot system first. Optionally, the preset BOOT file may be a BOOT file.
In some embodiments, the activation device may transmit the preset boot File to the slave device through a simple File Transfer Protocol (TFTP) service.
And step 105, sending the operating system installation file to the slave device according to the operating system installation request. The operating system installation file may include an operating system installation medium and operating system configuration information. The operating system installation medium is used for installing the operating system from the equipment, and the operating system configuration information is used for indicating the relevant parameter configuration of the slave equipment in the process of installing the system. For example, how the slave performs partitioning operations, which packages are preinstalled by the slave, optimization and setting of kernel parameters of the slave, and the like. Alternatively, the operating system installation medium may be an image file of the operating system.
And 106, after receiving feedback information of the operating system installation completion sent by the slave equipment, establishing a master server access identifier for the slave equipment, wherein the master server access identifier is used for the slave equipment to access a master server of the distributed database. The HOST server access identifier may be implemented in the form of a HOST file, and the HOST file includes a mapping relationship between a domain name of the HOST server and an IP address. When a server or a website is accessed, the access is usually performed through a network domain name, and specifically, the network domain name needs to be resolved first during the access to obtain an IP address corresponding to the network domain name. And when the analysis is successful and the IP address is obtained, the corresponding server or website can be normally accessed according to the obtained IP address. However, since the network domain name of the server is generally encrypted and cannot be directly resolved to obtain the corresponding IP address, the HOST file is configured such that the slave device directly reads the mapping relationship between the network domain name and the IP address of the HOST server in the HOST file, so that the slave device can perform the access operation of the HOST server and become one member of the distributed storage data.
In some embodiments, the activation device may establish a master server access identity for the slave device based on the playbook program of the ansable automation operation and maintenance tool. Specifically, the activation device may send an operating system login instruction with a preset key to the slave device to obtain a system operating right for the slave device. By using the preset secret key, the activating device can obtain the system operation authority of the slave device under the condition that a password does not need to be manually input, and the activating device can modify the system file of the slave device. The activation device may then establish a master server access identity in the system of slave devices.
In some embodiments, after the activation device receives the feedback information of the completion of the installation of the operating system sent by the slave device, the domain name system configuration and the hypertext transfer protocol configuration may be further performed on the slave device according to the preset network service information, so as to establish a basic network service for the slave device.
In some embodiments, before the slave device is deployed, the activation device may further perform a self-test operation to avoid a failure in the slave device deployment due to a program failure or a hardware failure. As shown in fig. 2, the method comprises the following processing steps:
And step 203, if the two are not consistent, changing the storage position of the preset guide file stored in the file reference list according to the actual storage position of the preset guide file.
And step 205, if the two files are not consistent, changing the storage position of the operating system installation file stored in the file reference list according to the actual storage position of the operating system installation file.
Fig. 3 is a flowchart of a distributed database deployment method applied to a slave device according to an embodiment of the present invention. As shown in fig. 3, the method includes:
And step 304, after receiving the operating system installation file sent by the activation equipment, installing the operating system according to the operating system installation file. In some embodiments, the operating system installation file includes operating system installation media and operating system configuration information, and the slave device may perform operating system installation using a kickstart script and configure system parameters of the operating system according to the operating system configuration information.
And 305, after the operating system is determined to be installed, sending feedback information of the installed operating system to the activation equipment, and accessing the main server according to the main server access identifier established by the activation equipment.
