【宋词】《绮寮怨》 周邦彦：上马人扶残醉，晓风吹未醒。映水曲、翠瓦朱檐，垂杨里、乍见津亭。当时曾题败壁，蛛丝罩、淡墨苔晕青。念去来、岁月如流，

Deploy and Test Clusters in Rancher: Load Balancing and Redis Locking via CLI for Better Performance

Simulate 8 tasks. The synchronization times (minutes) for transaction IDs 57, 58, 59, 63, 64, 65, 68, and 69 are 11, 12, 13, 12, 11, 12, 11, and 12 respectively. The synchronization counts for transaction IDs 57, 58, 59, 63, 64, 65, 68, and 69 are 21, 22, 22, 19, 17, 5, 17, and 17 respectively. The synchronization frequencies for transaction IDs 57, 58, 59, 63, 64, 65, 68, and 69 are 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, and 12 * 60 / 17 = 42 respectively. The average value is: (31 + 33 + 35 + 38 + 39 + 144 + 39 + 42) / 8 = 50. The theoretical calculation formula is round up (number of transactions / 5) / number of containers * 60. This meets expectations

1. In Rancher, clone the existing Docker container channel-pub-api-prev to channel-pub-api-prev-1 and channel-pub-api-prev-2, as shown in Figure 1.

2. The 3 containers ultimately form a cluster, as shown in Figure 2.

3. In load balancing, add a service rule to map the domain to the target containers, as shown in Figure 3.

4. I executed 2 requests in Postman: the first was a GET, and the second was a POST. Ultimately, there was one GET request log in container channel-pub-api-prev, one POST request log in container channel-pub-api-prev-1, and no request logs in container channel-pub-api-prev-2. The load balancing settings met expectations, as shown in Figure 4.

5. All 3 containers are listening to the queue based on Supervisor. In the service called by the queue, logs are output to a file. Ultimately, there is one service log in container channel-pub-api-prev, indicating that the queue job was executed in container channel-pub-api-prev. As shown in Figure 5.

6. Checking the Redis lock logs under the command line, there are not only logs for checking whether the Redis model lock exists (already exists), but also logs for failing to implement the Redis model lock. Time: 14:58 – 14:50 = 9 minutes. Number of locks: 29 + 31 + 10 = 70. Lock frequency: 70 / 9 = 8, that is, 8 times per minute. As shown in Figure 6.

7. The root cause of the excessively high lock frequency should be that only the same single task is executing in the command line. I decided to simulate 6 tasks, and the lock frequency should decrease. Time: 15:52 – 15:47 = 6 minutes. Number of locks: 47 + 34 + 45 = 126. Lock frequency: 126 / 6 = 9, that is, 20 times per minute. This does not meet expectations.

8. I decided to adjust bash sleep 3 to bash sleep 60, meaning that after the command line runs once, it runs again after a 60-second interval instead of 3 seconds. Repeating step 7, there are no Redis lock logs. This meets expectations.

9. Based on the synchronization time and ID ordering (penguin account transactions). When a certain task starts executing, update the synchronization time of the penguin account transaction to the current time to improve execution performance and further reduce the lock frequency.

PHP

        // 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. Simulate 3 tasks. The synchronization times (minutes) for transaction IDs 41, 42, and 43 are 9, 9, and 8 respectively. The synchronization counts for transaction IDs 41, 42, and 43 are 22, 20, and 17 respectively. The synchronization frequencies for transaction IDs 41, 42, and 43 are 9 * 60 / 22 = 25, 9 * 60 / 20 = 27, and 8 * 60 / 17 = 28 respectively. The average value is: (25 + 27 + 28) / 3 = 27. The theoretical calculation formula is round up (number of transactions / 5) / number of containers * 60. This meets expectations. As shown in Figure 7.

11. Simulate 5 tasks. The synchronization times (minutes) for transaction IDs 47, 48, 49, 52, and 53 are 4, 11, 4, 5, and 5 respectively. The synchronization counts for transaction IDs 47, 48, 49, 52, and 53 are 10, 20, 10, 9, and 10 respectively. The synchronization frequencies for transaction IDs 47, 48, 49, 52, and 53 are 4 * 60 / 10 = 24, 11 * 60 / 20 = 33, 4 * 60 / 10 = 24, 5 * 60 / 9 = 33, and 5 * 60 / 10 = 30 respectively. The average value is: (24 + 33 + 24 + 33 + 30) / 5 = 29. The theoretical calculation formula is round up (number of transactions / 5) / number of containers * 60. This meets expectations. As shown in Figure 8.
