in the operation and maintenance process of Cloud as a Service, repeatedly building the same environment is not only time-consuming and labor-intensive, but also prone to configuration deviations. As a replicable server environment template, Cloud as a Service ECS image can quickly deploy consistent server instances in batches, greatly improving operation and maintenance efficiency. This article will disassemble the production process of Cloud as a Service ECS image in an all-round way from preparation, practical steps to post-verification, and share the key points of pit avoidance to help zero-based users to complete the production smoothly.
formal production of Cloud as a Service ECS image, adequate preparation is the key to ensure that the image is available and free of redundancy, which can effectively avoid subsequent problems such as image failure and configuration failure.
1, cleaning server redundant data
first clean up the source Cloud as a Service ECS, delete temporary log files, cache files, unused packages and test data, avoid these redundant content occupying the image storage space, and prevent sensitive data from leaking with the image. It is recommended to clean the system log directory, application cache directory, and all contents in the user's temporary folder.
2, complete environment configuration and test
ensure that all applications, system parameters, and dependent components on the source server have been configured and tested to run normally, such as port settings for web services, database permission configuration, application startup scripts, etc. Only when the source environment fully meets the requirements can the produced Cloud as a Service ECS image be directly used for batch deployment.
3 Confirm server status and permissions
check whether the source Cloud as a Service ECS is in normal operation, no hardware failure or system error; at the same time confirm that the current operation account has the authority to make mirrors, some cloud platforms need to open the relevant permissions of mirror production in advance, to avoid half of the operation due to insufficient permissions and interrupt.
ready to work, you can enter the actual production of Cloud as a Service ECS image, the operation logic of different cloud platforms is basically the same, the following is the general step-by-step operation process.
1, enter the cloud platform mirror management interface
log in to the console of the corresponding cloud platform, find the Cloud as a Service ECS management module, enter the image management page, select the custom image category, click the Create Mirror button, and select Create Cloud as a Service ECS image from the instance in the pop-up option.
2, Configure mirror basic information
select the source Cloud as a Service ECS instance that needs to be mirrored, fill in the mirror name and description information, and the name is recommended to be set to a logo that can reflect the purpose of the mirror, such as the e-commerce production environment mirror, and the description can briefly record the application version and system version contained in the mirror.
3, wait for the mirror to be completed and verify
submit the creation request, the cloud platform will automatically take a snapshot of the source server and make a mirror. This process takes a few minutes to tens of minutes, depending on the disk capacity of the source server. After the production is completed, you can view the status of the Cloud as a Service ECS image in the custom mirror list. The status shows that it is available, which means the production is completed.
making a Cloud as a Service ECS image, some easily overlooked details will directly affect the usability and practicality of the image. Knowing these precautions in advance can effectively avoid risks.
1, avoid making
during peak business hoursmake Cloud as a Service ECS image, the cloud platform will take a snapshot of the source server disk, which will occupy a certain amount of server resources and may lead to slower business response. Therefore, it is recommended to choose a low peak period for production, such as early morning hours, to avoid affecting the normal operation of business.
2, do not include dynamic configuration information
make Cloud as a Service ECS image, to avoid dynamic configuration information written to the image, such as the server's Internet Protocol Address, host name, unique identity, etc., these information need to be reconfigured in the new instance, if written in advance of the image, will lead to configuration conflicts after the new instance starts, can not provide normal services.
3, regularly update the Cloud as a Service ECS image
as the application version iterates and the system patch is updated, the old Cloud as a Service ECS image will gradually fail to meet the needs. It is recommended to regularly remake the image based on the latest server environment, and delete the old image that is no longer used in time to save the storage space cost of the cloud platform.
To sum up, the production of Cloud as a Service ECS mirror needs to complete the three core links of preparation, step-by-step operation and detail control in sequence. From cleaning the redundant data of the source server to completing the image verification, each step directly affects the quality of the mirror. Through the standardized production process, the available Cloud as a Service ECS image can be quickly generated, and the one-click replication of the server environment can be realized, which greatly reduces the operation and maintenance cost and improves the efficiency of business deployment.
