在 Yii 2.0 中，控制台命令的集群实现，Redis模型的锁定实现(以保证同一时间段内，即使多台服务器皆在运行命令行，但是每台服务器运行的任务是不重复的，以提升命令行的总体处理性能)
1、Docker 部署，基于 Supervisor 的 crontab (bash sleep) 的实现，以降低内存占用，参考：https://www.shuijingwanwq.com/2019/10/12/3555/ 。/console/controllers/CmcConsoleUserController.php

2、break 结束当前 foreach 结构的执行，即命令行的每一次运行，仅同步成功一个租户下的用户列表。当租户数量过多的时候，假设 100 个租户，平均 1 个租户的同步时间为 10 秒钟 + 下一个租户的同步的间隔时间 60 秒(包含了 bash sleep 5 秒)，那么可能某个租户下的用户同步，其最大间隔时间就有可能为 7000 秒钟了。因此，如果支持了集群的部署，假设为 10 个容器，那么某个租户下的用户同步，其最大间隔时间就有可能为 700 秒钟了，同步的即时性提升了 10 倍。/mcloud/yii-cmc-console-user-sync.ini
[program:yii-cmc-console-user-sync] command = bash -c 'sleep 5 && exec php /mcloud/www/pcs-api/yii cmc-console-user/sync' autorestart = true startsecs = 5 stopwaitsecs = 10 stderr_logfile = /data/logs/yii-cmc-console-user-sync-stderr.log stdout_logfile = /data/logs/yii-cmc-console-user-sync-stdout.log
3、如果要支持集群的部署，现阶段存在的问题：同一个租户下的用户同步，可能在某一时间段，多个容器皆在执行，导致了同步的冗余执行(未达到最大化利用集群部署，进而满足同步的即时性提升至 10 倍的理想值)。因此，应该保证同一个租户下的用户同步，在某一时间段，仅在 1 个容器中执行。
4、将同步标识存放到缓存供下次使用，将数据在缓存中保留 60 秒。之前实现的初衷是同步成功一个租户下的用户后，间隔 60 秒再同步下一个租户下的用户，以降低资源消耗。现在如果要支持集群，就需要取消。否则会导致某个容器同步成功一个租户下的用户后，在 60 秒的间隔时间段内，其他容器也无法同步其他租户下的用户。/console/controllers/CmcConsoleUserController.php

8、当一个租户下的用户同步时间长度小于等于 Redis锁定超时时间 的值 10秒时(sleep(8)，实际长度超过了 8 秒)，此时，此租户已经处于锁定状态，进而导致部署为集群时，可以保证同一个租户下的用户同步，在某一时间段，仅在 1 个容器中执行。在本地环境中，模拟了 3 个容器，3 个容器开始同步时间：1582784312、1582784315、1582784318，分别间隔 3 秒、3秒，皆小于 10 秒。第 1 个容器同步了租户：c10e87f39873512a16727e17f57456a5，第 2 个容器同步了租户：015ce30b116ce86058fa6ab4fea4ac63，第 3 个容器同步了租户：4fd58ceba1fbc537b5402302702131eb。3 个容器的并行执行，分别同步了 3 个租户，符合预期。文件生成顺序体现出了执行执行流程。如图1

9、打印出从缓存中取回租户ID列表，已经成功同步了 3 个租户：c10e87f39873512a16727e17f57456a5、015ce30b116ce86058fa6ab4fea4ac63、4fd58ceba1fbc537b5402302702131eb，但是，仅有租户 4fd58ceba1fbc537b5402302702131eb 的同步时间得到了更新。虽然在实际的生产环境中，不存在 sleep(8)，此为在本地环境模拟并发请求，而添加的。但是，理论上来说，从缓存中取回租户ID列表，到 将 $cmcApiGroupIds 存放到缓存供下次使用，将数据在缓存中永久保留 的间隔时间段(假设租户数量为 10000 个，则遍历 10000 次，时间间隔为 30000 微秒，即 0.03 秒)内，如果存在 多个容器 在运行的话，便会出现相互覆盖的情况。暂时不做处理，即时出现了相互覆盖的情况，其后果是可以接受的。租户：c10e87f39873512a16727e17f57456a5、015ce30b116ce86058fa6ab4fea4ac63 会相继立即重复同步一次。如图2

)
)
10、当一个租户下的用户同步时间长度超过 Redis锁定超时时间 的值 10秒后(sleep(60)，实际长度超过了 60 秒)，此时，此租户已经被自动解除锁定，进而导致部署为集群时，无法保证同一个租户下的用户同步，在某一时间段，仅在 1 个容器中执行。在本地环境中，模拟了 3 个容器，3 个容器开始同步时间：1582773882、1582773895、1582773917，分别间隔 13 秒、22秒，皆大于 10 秒。第 3 个容器开始同步时，第 1 个容器仍然在同步中，并未结束(释放锁定)。因此，租户：c10e87f39873512a16727e17f57456a5 被 3 个容器同时同步。如图3
图3
// 将 $cmcApiGroupIds 存放到缓存供下次使用，将数据在缓存中永久保留
sleep(60);
$redisCache->set($redisCacheGroupIdsKey, $cmcApiGroupIds);
// 释放锁定
$redisLock->unlock($redisLockKeyName);
11、编辑 /common/logics/redis/Lock.php。public function lock($lockKeyName)，添加一个参数，支持自定义Redis锁定超时时间。以基于场景灵活设置。
/**
* Redis模型的锁定实现
* @param string $lockKeyName 锁定键名
* 格式如下：
*
* 'game_category' //锁定键名，如比赛分类
*
* @param int $timeOut Redis锁定超时时间，单位为秒
* 格式如下：3
*
* @return bool 成功返回真/失败返回假
* 格式如下：
*
* true //状态，获取锁定成功，可继续执行
*
* 或者
*
* false //状态，获取锁定失败，不可继续执行
*
*/
public function lock($lockKeyName, $timeOut = 3)
{
// 设置锁定的过期时间，获取相关锁定参数
$time = time();
$lockKey = Yii::$app->params['redisLock']['keyPrefix'] . $lockKeyName;
$lockExpire = $time + $timeOut;
// 获取 Redis 连接，以执行相关命令
$redis = Yii::$app->redis;
// 获取锁定
$executeCommandResult = $redis->setnx($lockKey, $lockExpire);
// 返回0，表示已经被其他客户端锁定
if ($executeCommandResult == 0) {
// 防止死锁，获取当前锁的过期时间
$lockCurrentExpire = $redis->get($lockKey);
// 判断锁是否过期，如果已经过期
if ($time > $lockCurrentExpire) {
// 防止并发锁定，检查存储在 key 的旧值是否仍然是过期的时间戳，如果是，则获取锁定，否则返回假
$executeCommandResult = $redis->getset($lockKey, $lockExpire);
if ($lockCurrentExpire != $executeCommandResult) {
return false;
}
}
// 返回0，表示已经被其他客户端锁定，且不存在死锁，返回假
if ($executeCommandResult == 0) {
return false;
}
}
return true;
}
12、Redis模型的锁定实现，Redis锁定超时时间，单位为秒(自定义 600)。一个租户下的用户同步，耗费的最长时间只要不超过 10 分钟，当部署为集群时，就可以保证同一个租户下的用户同步，在某一时间段，仅在 1 个容器中执行。
/* Redis模型的锁定实现 */
$lock = $redisLock->lock($redisLockKeyName, 600);
13、在开发环境，部署了 3 个容器。以便于测试集群部署时，并发锁定的情况。在 bash sleep 60 秒 的情况下，很难出现并发锁定的情况。不过，当部署为集群时，已经可以保证同一个租户下的用户同步，在某一时间段，仅在 1 个容器中执行。当出现租户下的用户同步及时性不够理想的情况，可以通过添加容器的方案提升同步的及时性。在 3 个容器中，总计同步了 30 + 30 + 33 = 93 次。其中 租户 f53df1a8d46108afc8ae9eeb3f0e1f0e、c10e87f39873512a16727e17f57456a5、4fd58ceba1fbc537b5402302702131eb、015ce30b116ce86058fa6ab4fea4ac63 分别同步了：23、24、22、24 次。3 个容器的情况下，在 15:43 至 16:16 的时间段内(32 分钟左右)，一个租户的同步次数平均为：23 次。实际测试结果，一个租户的同步时间间隔为：32 * 60 / 24 = 80 秒。理论上的计算公式，一个租户的同步时间间隔为：租户数量 / 容器数量 * 60，结果单位为秒。同步性能符合设计预期。如图4

14、在 bash sleep 60 秒 的情况下，很难出现并发锁定的情况。或者增加更多的容器，或者提升执行命令行的频率。设置 bash sleep 10 秒。已经出现并发锁定(防止同一个租户下的用户同步同时在多个容器中执行)的情况。当部署为集群时，已经可以保证同一个租户下的用户同步，在某一时间段，仅在 1 个容器中执行。理论上的计算公式，一个租户的同步时间间隔为：4 / 3 * 10 = 13，结果单位为秒。符合设计预期。总结：部署的容器数量不要超过租户的数量，以防止并发锁定的情况过于频繁。如图5

15、总结：
(1) 理论上的计算公式，一个租户的同步时间间隔为：租户数量 / 容器数量 * 60，结果单位为秒。
(2) 部署的容器数量不要超过租户的数量，以防止并发锁定的情况过于频繁，且必要性不大(当容器数量等于租户数量时，同步时间间隔为：60 秒)。
