Deploy and test clusters in Rancher
1. In Rancher, clone the existing Docker container channel-pub-api-prev is channel-pub-api-prev-1, channel-pub-api-prev-2, as shown in Figure 1
Figure 1
2. The final 3 containers form a cluster, as shown in Figure 2
Figure 2
3. In the load balancing, add service rules and set the mapping relationship between the domain name and the target container, as shown in Figure 3
Figure 3
4. 2 requests are executed in postman, the first time is GET, the second time is POST, and finally there is a get request log in the container channel-pub-api-prev, in the container There is a POST request log in channel-pub-api-prev-1, there is no request log in the container channel-pub-api-prev-2, and the load balancing setting is as expected, as shown in Figure 4
Figure 4
5. In the 3 containers, the queue is based on the supervisor. In the service called by the queue, the output log is to the file, and finally the container channel-pub-api-prev There is a service log that indicates that the queue job is executed in the container channel-pub-api-prev. as shown in Figure 5
Figure 5
6. Check the Redis lock logs under the command line, not only to determine whether the lock of the Redis model exists (existing), but also the log that fails when the lock implementation of the Redis model is implemented. 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 high lock frequency should be that only the same task is executed in the command line. Determined to simulate 6 tasks, the lock frequency should be reduced. 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. Not as expected.

8. Decide to adjust Bash Sleep 3 to Bash Sleep 60, that is, after the command line runs once, run it again after 60 seconds, instead of 3 seconds. Repeat step 7, the Redis lock log does not exist. in line with expectations.
9. Arranged based on synchronization time and ID order (the transaction of the penguin number). When a task starts to execute, the synchronization time of the transaction of the update Penguin is the current time, so as to improve the execution performance and reduce the lock frequency again.
// 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)

10. Simulate 3 tasks. The synchronization time (minutes) of transaction IDs 41, 42, and 43 are: 9, 9, and 8, respectively. The number of synchronization times with transaction IDs 41, 42, and 43 is: 22, 20, and 17, respectively. The synchronization frequencies of the transaction IDs 41, 42, and 43 are: 9 * 60 / 22 = 25, 9 * 60 / 20 = 27, 8 * 60 / 17 = 28. Get the average: (25 + 27 + 28) / 3 = 27. The theoretical calculation formula, the further method is rounded (the number of transactions / 5) / the number of containers * 60. in line with expectations. as shown in Figure 7

12. Simulate 8 tasks. The synchronization time (minutes) of transaction IDs 57, 58, 59, 63, 64, 65, 68, and 69 are: 11, 12, 13, 12, 11, 12, 11, 12, respectively. The number of synchronizations with transaction IDs 57, 58, 59, 63, 64, 65, 68, and 69 are: 21, 22, 22, 19, 17, 5, 17, 17, respectively. The sync frequency of the transaction IDs 57, 58, 59, 63, 64, 65, 68, and 69 is: 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. Get averages: (31 + 33 + 35 + 38 + 39 + 144 + 39 + 42) / 8 = 50. The theoretical calculation formula, the further method is rounded (the number of transactions / 5) / the number of containers * 60. in line with expectations. as shown in Figure 9
