As an experienced website operations expert, I know the efficiency and convenience of AnQiCMS in enterprise content management.It not only provides a powerful set of features, but also considers many aspects of system stability and maintainability.start.shandstop.shScript, a deep understanding is the key to ensure the continuous and healthy operation of the website.

Today, let's delve into a seemingly simple yet rich in operational wisdom issue: When will the AnQiCMS scheduled task trigger execution?stop.shWhen will the script trigger execution?

一、Regular maintenance and planned termination: A key link in the system's self-healing mechanism

In the practice of deploying AnQiCMS, especially when installing in integrated environments such as Baota Panel,stop.shThe most common trigger time for a script is as an itemScheduled tasks. According to the instructions in the installation document,stop.shit is usually configured as aexecuted once a monthThe scheduled task.

This is not by chance, but a subtle balance point in the AnQiCMS operation and maintenance strategy. We know,start.shThe script is designed as a high-frequency running (such as, executed once a minute) scheduled task, its core mission is to continuously monitor the running process of AnQiCMS. Once it detects the main program (anqicmsExecutable file is not running, it will launch it immediately to ensure the continuity of the service.

whilestop.shthen withstart.shEstablished a complementary 'guardian' relationship. Its script logic is very direct: it checks if there is a process namedanqicmsand if it exists, it will use it without hesitation.kill -9command to force terminate the process.

This monthly plan of forced termination is designed with deep intentionSystematic maintenance and resource refreshment. Long-running applications, even after optimization, may face some potential issues, such as:

  • Memory leak:Even though Go language has an excellent garbage collection mechanism, some complex business logic or third-party libraries may still cause minor memory leaks, which, when accumulated, can affect performance.Regular restarts can effectively release these resources.
  • Zombie process or handle leak:In extreme cases, some difficult-to-completely-clean-up background processes or file handles may be generated, which do not affect the main functions but will consume system resources.Forcefully terminate and restart can clear this "garbage".
  • Configuration update生效:Although most configurations of AnQiCMS support hot loading, some deep or complex system-level configuration changes may require a complete process restart to take full effect.
  • Provide a clean environment for other maintenance operations:In some cases, the underlying maintenance of the server (such as operating system updates, storage optimization) may require AnQiCMS to be completely stopped running, regularstop.shOpportunity provided for these operations.

Therefore,stop.shMonthly regular execution combined withstart.shThe quick startup, forming a 'periodic refresh-quick recovery' self-healing process management cycle, ensures that AnQiCMS can maintain a relatively healthy and stable running state even without human intervention.

二、Administrator manual intervention: dealing with specific operation and maintenance needs

In addition to systematic scheduled tasks,stop.shAnother important trigger time for scripts isAdministrator manual interventionAs website operation experts, we often encounter situations where we need to temporarily stop the AnQiCMS service to perform specific operation and maintenance tasks.stop.shIt has become a quick and effective tool.

Admin manually triggersstop.shCommon scenarios include:

  • System version upgrade:When upgrading to a new version of AnQiCMS, in order to ensure the smooth progress of the upgrade process and avoid file conflicts or data inconsistencies, the administrator will manually stop the services that are currently running.
  • Database-level deep maintenance:When operations such as major version upgrades, data structure optimizations, and migration to new storage devices are required for MySQL databases, it is usually required for the upper application services to be completely stopped to ensure data integrity.
  • Server underlying adjustment：If it is necessary to upgrade the hardware of the AnQiCMS hosting server (such as increasing memory, replacing CPU), replacing the operating system, making major adjustments to network configuration, etc., stopping the AnQiCMS service is indispensable.
  • Emergency Fault Diagnosis:When the website encounters serious exceptions, sudden performance degradation, or frequent errors, but the log analysis cannot quickly locate the problem, stopping the service and checking each dependent item one by one is a commonly used troubleshooting method.
  • Backup or restore operation:Perform offline backup of the entire site files or database, or stop AnQiCMS in disaster recovery to minimize the risk of data damage.

In these cases, the administrator can directly log into the server and execute commands via the command line./stop.shCommand. This script will quickly locate and terminate the AnQiCMS process, creating conditions for subsequent maintenance work.

III,stop.shWithstart.shcollaboration and efficiency

[en]Again, I emphasize,stop.shis not isolated, it is related tostart.shEstablished a tight collaborative relationship. When we manually executestop.shit will terminateanqicmsthe process. Subsequently,start.shAs a high-frequency scheduled task, it will detect in its next execution cycle (usually within a few seconds)anqicmsIf the process has stopped, it will be restarted immediately.

This design allows AnQiCMS to stop the service quickly and controllably when necessary. Whether it is a planned monthly refresh or the immediate intervention of the administrator, the system can restore the service in the shortest possible time, minimizing the impact on the website as much as possible.
