1、在 Rancher 中，克隆已经存在的 Docker 容器 channel-pub-api-prev 为 channel-pub-api-prev-1、channel-pub-api-prev-2，如图1
图1
2、最终 3 个容器组成了一个集群，如图2
图2
3、在负载均衡中，添加服务规则，设置域名与目标容器的映射关系，如图3
图3
4、在 Postman 中执行了 2 次请求，第 1 次为 GET，第 2 次为 POST，最终在容器 channel-pub-api-prev 中有一条 GET 请求日志，在容器 channel-pub-api-prev-1 中有一条 POST 请求日志，在容器 channel-pub-api-prev-2 中无请求日志，负载均衡设置符合预期，如图4
图4
5、在 3 个容器中，均在基于 Supervisor 监听队列，在队列所调用的服务中，输出日志至文件中，最终在容器 channel-pub-api-prev 中有一条服务日志，表明队列作业在容器 channel-pub-api-prev 中执行的。如图5
图5
6、查看 命令行下的 Redis 锁定日志，不仅存在 判断Redis模型的锁定是否存在(已存在)，而且存在 Redis模型的锁定实现时失败的 日志。时间：14:58 – 14:50 = 9 分钟。锁定次数：29 + 31 + 10 = 70 。锁定频率：70 / 9 = 8，即每分钟 8 次。如图6

7、锁定频率过高的根源应该在于命令行中仅有同一条任务在执行。决定模拟出 6 条任务，锁定频率应该会有所下降。时间：15:52 – 15:47 = 6 分钟。锁定次数：47 + 34 + 45 = 126 。锁定频率：126 / 6 = 9，即每分钟 20 次。不符合预期。

8、决定调整 bash sleep 3 为 bash sleep 60，即命令行运行一次后，间隔 60 秒后再次运行，而不是 3 秒。重复第 7 步骤，不存在 Redis 锁定日志。符合预期。
9、基于同步时间、ID顺序排列(企鹅号的事务)。某一任务开始执行时，更新企鹅号的事务的同步时间为当前时间 ，以提升执行性能，且再次降低锁定频率。
// 查询企鹅号的应用类型，cw：内容网站应用 && 类型，1：文章 && 状态，3：处理中 && 文章发布状态：审核中的5条记录，基于同步时间、ID顺序排列(企鹅号的事务)
$qqTransactionArticleItems = QqTransaction::find()->where(['qq_app_type' => QqArticle::QQ_APP_TYPE_CW, 'type' => QqTransaction::TYPE_ARTICLE, 'article_pub_flag' => HttpQqApiTransaction::ARTICLE_PUB_FLAG_REVIEW])->isDeletedNo()->processing()->orderBy(['synced_at' => SORT_ASC, 'id' => SORT_ASC])->limit(5)->all();
if ($qqTransactionArticleItems) {
foreach ($qqTransactionArticleItems as $qqTransactionArticleItem) {
/* 判断Redis模型的锁定是否存在 */
$redisLockKeyName = 'qq_cw_transaction_article:sync:' . implode(':', ['id' => $qqTransactionArticleItem->id]);
$redisLock = new RedisLock();
$isLockExist = $redisLock->isLockExist($redisLockKeyName);
// 返回 true，表示锁定存在，即已经被其他客户端锁定
if ($isLockExist === true) {
continue;
}
/* Redis模型的锁定实现 */
$lock = $redisLock->lock($redisLockKeyName, 600);
// 返回 false，表示已经被其他客户端锁定
if ($lock === false) {
continue;
}
// 基于ID查找单个数据模型(企鹅号的事务)
$qqTransactionArticleItem = QqTransaction::findOne($qqTransactionArticleItem->id);
// 更新企鹅号的事务的同步时间
$qqTransactionArticleItem->synced_at = time();
$qqTransactionArticleItem->update();
file_put_contents('/mcloud/www/channel-pub-api/console/runtime/logs/qq-cw-transaction-article-sync-' . $qqTransactionArticleItem->id . '-' . time() . '.txt', $qqTransactionArticleItem->id);
}
}
10、模拟出 3 条任务。事务ID为 41、42、43 的同步时间(分钟)分别为：9、9、8 。事务ID为 41、42、43 的同步次数分别为：22、20、17 。事务ID为 41、42、43 的同步频率分别为：9 * 60 / 22 = 25、9 * 60 / 20 = 27、8 * 60 / 17 = 28。得出平均值：(25 + 27 + 28) / 3 = 27。理论上的计算公式，进一法取整(事务数量 / 5) / 容器数量 * 60。符合预期。如图7

12、模拟出 8 条任务。事务ID为 57、58、59、63、64、65、68、69 的同步时间(分钟)分别为：11、12、13、12、11、12、11、12 。事务ID为 57、58、59、63、64、65、68、69 的同步次数分别为：21、22、22、19、17、5、17、17 。事务ID为 57、58、59、63、64、65、68、69 的同步频率分别为：11 * 60 / 21 = 31、12 * 60 / 22 = 33、13 * 60 / 22 = 35、12 * 60 / 19 = 38、11 * 60 / 17 = 39、12 * 60 / 5 = 144、11 * 60 / 17 = 39、12 * 60 / 17 = 42。得出平均值：(31 + 33 + 35 + 38 + 39 + 144 + 39 + 42) / 8 = 50。理论上的计算公式，进一法取整(事务数量 / 5) / 容器数量 * 60。符合预期。如图9
