In the multi-site operation of Anqi CMS, efficiency and stability are always the core pursuit.As a CMS system developed in Go language, AnQiCMS has won the favor of many operators with its excellent performance and multi-site management capabilities.crontabTask update, ensure a smooth transition for all sites, this is undoubtedly a problem that many operation experts need to ponder over.Today, let's delve into this topic in depth and provide you with a set of effective strategies.
Understanding AnQiCMS andcrontabTask associations
Firstly, we need to clarify the relationship between AnQiCMS andcrontabthe task. The operation mechanism of AnQiCMS, especially its multi-site management mode, is forcrontabThe configuration of the task has a direct impact.According to the deployment guide of AnQiCMS, in most cases, a single instance of the AnQiCMS core program can manage multiple frontend sites.This means that, regardless of how many child sites you have created through the "Multi-site Management" feature in the background, they are often served by the same AnQiCMS process.
The lifecycle management of this core process, such as automatic startup after server restart or automatic recovery after an unexpected program termination, is often ensured bycrontabtasks. TypicalcrontabConfigure will execute a task at regular intervals (for example, every minute)start.shscript, which is responsible for checking if the AnQiCMS process is alive, and if it does not exist, it will start it up.
However, it is worth noting that the deployment modes of AnQiCMS also exist in diversity.Some users may choose to deploy multiple independent AnQiCMS instances, each instance occupying a different port and serving different websites.start.shscript and its correspondingcrontabEntry. Understanding your specific deployment model is essential for efficient managementcrontabis the first step of the task.
when performing batch upgradescrontabare the core principles of task updates
When performing batch upgrades of AnQiCMS, whether upgrading multiple sites managed by a single core program or upgrading multiple independent instances,crontabThe updates to tasks should follow a core principle:Disable the old task and start the new task.The upgrade process of AnQiCMS is usually not as simple as replacing binary files, but may also involve updating dependencies, fine-tuning startup script logic, and even changes in port configuration.crontabentries, and re-add them according to the deployment requirements of the new version.
The official upgrade document of AnQiCMS (especially the upgrade guide from 2.x to 3.x) also clearly suggests: Before upgrading, it is recommended to stop the project through the scheduled task first, then delete the old scheduled task, and finally reconfigure according to the requirements of the new version.crontabThe task provides clear guidance.
Batch UpdatecrontabPractical Strategies for Tasks
Now, let's delve into how to update all related items at once when upgrading AnQiCMS multi-site in bulk,crontabtask.
Step 1: Thorough preparation, no room for error.
Before making any changes to the production environment configuration, data backup and current situation recording are essential.
- Backup all.
crontabTask: Executecrontab -l > /path/to/backup/crontab_backup_$(date +%Y%m%d%H%M%S).txtCommand, backup all tasks of the current user.crontabThis will provide a complete history for rollback in case it is needed. - Confirm deployment of the model.Check your server to confirm whether it is a single AnQiCMS instance managing all sites or if there are multiple independent AnQiCMS instances. This determines what actions you need to take.
