1. Supervisor is a small system that can manage and monitor various processes in UNIX-like systems. Supervisor’s configuration file is a Windows-INI-style (Python ConfigParser) file.

2. The program configuration section in Supervisor’s configuration file

INI

; * 为必选项
;[program:theprogramname]
;command=/bin/cat              ; * 要执行的命令路径(可以是相对与 PATH 的路径)也可带参数
;startsecs=1                   ; 需要考虑进程启动成功的时间, 当 running 状态超过该值时，表明启动成功 (def. 1)
;autorestart=unexpected        ; 当进程退出时是否应该重启，可选值为 false true unexpected ，为 false 时表示不重启，为 true 表示重启，为 unexpected 时，如果退出状态码不是 exitcodes 中之一时进行重启 (def: unexpected)
;stopwaitsecs=10               ; 这个是当我们向子进程发送 stopsignal 信号后，到系统返回信息给 supervisord，所等待的最大时间。超过这个时间，supervisord会向该子进程发送一个强制 kill 的信号。(default 10)
;stdout_logfile=/a/path        ; 进程 stdout 输出的日志文件路径，如果将其设置为NONE，则supervisord将不创建任何日志文件; default AUTO
;stderr_logfile=/a/path        ; 除非redirect_stderr为true，否则将进程 stderr 输出放在此文件中。日志文件路径，如果将其设置为NONE，则supervisord将不创建任何日志文件; default AUTO

3. Create \build\c_files\etc\supervisord.d\yii-task-submit.ini, as shown in Figure 1

Create \build\c_files\etc\supervisord.d\yii-task-submit.ini
Figure 1
INI

[program:yii-task-submit]
command = php /sobey/www/aims-rpc/yii task/submit
autorestart = true
startsecs = 0
stopwaitsecs = 10
stderr_logfile = /data/logs/yii-task-submit-stderr.log
stdout_logfile = /data/logs/yii-task-submit-stdout.log

4. stopwaitsecs: the number of seconds to wait for the operating system to return a SIGCHLD to supervisord after the program has been sent a stop signal. If this number of seconds elapses before supervisord receives a SIGCHLD from the process, supervisord will attempt to terminate it with a final SIGKILL. The command is now executed at a default interval of 1 second. For example, if the script execution time is 20 seconds, the interval will be 21 seconds.

5. I found that the result did not meet expectations after the command executed. I entered the container command line and checked /data/logs/yii-task-submit-stderr.log

6. After resolving the Rancher environment variable substitution issue, I upgraded again. The result met expectations after the command executed, but the output of some string print messages from the command did not wrap automatically, resulting in poor readability. I checked /data/logs/yii-task-submit-stderr.log, as shown in Figure 2

8. Edit \console\controllers\TaskController.php to add a newline character when outputting a message

PHP

/**
* 调用AI接口：提交任务
* 任务描述：
* 1、查询任务队列是否空闲，如果否，则退出；
* 2、获取1条任务，其条件与排序规则如下：
* (1)任务，状态：1(待提交)；
* (2)租户优先级，状态：1(启用)；
* (3)排序规则：group_pri.group_pri(顺序)，group_pri.group_pri_updated_at(倒序)，task.pri(顺序)，task.pri_updated_at(倒序)，task.created_at(顺序)；
* 3、获取1条任务，如果无，则退出；
* 4、获取当前任务的人工智能服务提交日志，如果为空，则提交，否则重做；
* 5、人工智能服务：提交任务/重做任务；
* 6、操作数据(事务)
* (1)创建MySQL模型(人工智能服务提交日志)；
* (2)更新任务模型的状态：2(已提交)，人工智能服务任务状态：1(处理中)；
* (3)创建MySQL模型(人工智能服务任务进度)；
*/
public function actionSubmit()
{

$service = new TaskService();
$submitResult = $service->submit();

if ($submitResult['status'] === false) {
$this->stderr($submitResult['message'] . "\n");
return $submitResult['code'];
}

return ExitCode::OK;
}

9. After upgrading, I checked /data/logs/yii-task-submit-stderr.log again; it now wraps automatically, as shown in Figure 3
