2、根源在于，需要将程序部署在华为云的ARM (鲲鹏)架构的云服务器上，因此，基础镜像换为一个支持 ARM 的镜像，进而 PHP 版本变化为：PHP 7.2.20。AArch64是Armv8-A架构中引入的64位状态。如图2

    "require": {
        "php": ">=7.2.0",
    },

5、将本地 Windows 环境的 PHP 版本切换至：7.2.14，与生产环境的镜像的 PHP 大版本：7.2.20 保持一致。如图5

图5

1、在 K8s 中，容器无重启选项，如图1

图1

2、在非 K8s 中，容器有重启选项，之前修改 PHP 文件，容器重启后自动生效。如图2

图2

3、编辑 PHP 文件，输出一些信息，如图3

图3



print_r($domain);
print_r($cooike_domain);
exit;

4、刷新页面，发现没有立即生效，如图4

图4

5、在 CentOS 中批量 kill php 进程，执行命令。管道符“|”用来隔开两个命令，管道符左边命令的输出会作为管道符右边命令的输入。下面说说用管道符联接起来的几个命令： “ps – ef”是 Red Hat 里查看所有进程的命令。这时检索出的进程将作为下一条命令“grep LOCAL=NO”的输入。 “grep php”的输出结果是，所有含有关键字“LOCAL=NO”的进程。 “grep -v grep”是在列出的进程中去除含有关键字“grep”的进程。 “cut -c 9-15”是截取输入行的第 9 个字符到第 15 个字符，而这正好是进程号 PID。 “xargs kill -9”中的 xargs 命令是用来把前面命令的输出结果 (PID) 作为“kill -9”命令的参数，并执行该命令。 “kill -9”会强行杀掉指定进程，这样就成功清除了 php 所有进程。如图5

图5

6、再次刷新页面，发现立即生效，符合预期。如图6

在 Yii 2.0 中，控制台命令行，添加参数的实现

永夜 — Fri, 29 May 2020 08:14:57 +0000

浏览量： 122

1、CmcConsoleUser/actionSync，现有实现，参考：https://www.shuijingwanwq.com/2020/03/02/3964/ ，现在需要添加参数：租户ID 2、参数将传递给请求的子命令对应的动作方法。设置参数 $groupId 的默认值为 null



public function actionSync($groupId = null)

3、判断 $groupId 是否为空，如果不为空，且在 $httpCmcApiGroupIds 中不存在，则成功退出



        /* 判断 $groupId 是否为空，如果不为空，且在 $httpCmcApiGroupIds 中不存在，则成功退出 */
        if (!empty($groupId) && !in_array($groupId, $httpCmcApiGroupIds)) {
            return ExitCode::OK;
        }

4、基于上次同步时间顺序排列，赋值给：$sortCmcApiGroupIds，打印排序前后的数组



        // 基于上次同步时间顺序排列，赋值给：$sortCmcApiGroupIds
        $sortCmcApiGroupIds = $cmcApiGroupIds;
        print_r($sortCmcApiGroupIds);
        ArrayHelper::multisort($sortCmcApiGroupIds, 'cmc_console_user_last_synced_at', SORT_ASC);
        print_r($sortCmcApiGroupIds);
        exit;



PS E:\wwwroot\pcs-api> ./yii cmc-console-user/sync

        )

    [3] => Array
        (
            [group_id] => e774bfcf8fc4cfe2ce57ac875a266e94
            [cmc_console_user_last_synced_at] => 0

    [5] => Array
        (
            [group_id] => c10e87f39873512a16727e17f57456a5
            [cmc_console_user_last_synced_at] => 1590649259
        )

)

5、现在需要基于参数 $groupId 的值，来同步此租户下的用户，即需要让此租户排在第一位。才能够满足需求。先销毁 $sortCmcApiGroupIds 中的 $groupId，再插入至开头。打印排序前后的数组。符合预期。如图1

图1



        // 基于上次同步时间顺序排列，赋值给：$sortCmcApiGroupIds
        $sortCmcApiGroupIds = $cmcApiGroupIds;
        print_r($sortCmcApiGroupIds);
        ArrayHelper::multisort($sortCmcApiGroupIds, 'cmc_console_user_last_synced_at', SORT_ASC);
        print_r($sortCmcApiGroupIds);

        /* 判断 $groupId 是否为空，如果不为空 */
        if (!empty($groupId)) {
            // 销毁 $sortCmcApiGroupIds 中的 $groupId
            foreach ($sortCmcApiGroupIds as $sortCmcApiGroupIdKey => $sortCmcApiGroupId) {
                if ($sortCmcApiGroupId['group_id'] == $groupId) {
                    unset($sortCmcApiGroupIds[$sortCmcApiGroupIdKey]);
                    break;
                }
            }
            print_r($sortCmcApiGroupIds);
            // 将 $groupId 插入至 $sortCmcApiGroupIds 的开头
            array_unshift($sortCmcApiGroupIds, [
                'group_id' => $groupId,
                'cmc_console_user_last_synced_at' => 0, //上次同步时间
            ]);
        }

        print_r($sortCmcApiGroupIds);
        exit;

6、最终的代码实现



        // 设置同步标识的缓存键
        $redisCache = Yii::$app->redisCache;

        // HTTP 请求，获取开通有效服务的租户ID列表
        $httpCmcApiGroupIds = CmcApiGroupService::httpGetGroupIds();

        /* 判断 $httpCmcApiGroupIds 是否为空，如果为空，则成功退出 */
        if (empty($httpCmcApiGroupIds)) {
            // 延缓执行 60 * 60 秒
            // sleep(Yii::$app->params['cmcConsoleUser']['isEmptyYesSleepTime']);

            return ExitCode::OK;
        }

        /* 判断 $groupId 是否为空，如果不为空，且在 $httpCmcApiGroupIds 中不存在，则成功退出 */
        if (!empty($groupId) && !in_array($groupId, $httpCmcApiGroupIds)) {
            return ExitCode::OK;
        }

        // 设置租户ID列表的缓存键
        $redisCacheGroupIdsKey = 'cmc_api_group_ids';

        // 从缓存中取回租户ID列表
        $redisCacheGroupIdsData = $redisCache[$redisCacheGroupIdsKey];

        // 是否设置租户ID列表的缓存，默认：否
        $isSetRedisCacheGroupIds = false;

        if ($redisCacheGroupIdsData === false) {
            $cmcApiGroupIds = [];
            foreach ($httpCmcApiGroupIds as $httpCmcApiGroupId) {
                $cmcApiGroupIds[] = [
                    'group_id' => $httpCmcApiGroupId,
                    'cmc_console_user_last_synced_at' => 0, //上次同步时间
                ];
            }
            // 是否设置租户ID列表的缓存：是
            $isSetRedisCacheGroupIds = true;
        } else {
            // 获取 group_id 值列表
            $redisCacheGroupIds = ArrayHelper::getColumn($redisCacheGroupIdsData, 'group_id');
            $cmcApiGroupIds = $redisCacheGroupIdsData;

            /* 删除出现在 $cmcApiGroupIds 中但是未出现在 $httpCmcApiGroupIds 中的租户 */
            foreach ($cmcApiGroupIds as $cmcApiGroupIdKey => $cmcApiGroupId) {
                if (!in_array($cmcApiGroupId['group_id'], $httpCmcApiGroupIds)) {
                    unset($cmcApiGroupIds[$cmcApiGroupIdKey]);
                    // 是否设置租户ID列表的缓存：是
                    $isSetRedisCacheGroupIds = true;
                }
            }

            foreach ($httpCmcApiGroupIds as $httpCmcApiGroupId) {
                if (!in_array($httpCmcApiGroupId, $redisCacheGroupIds)) {
                    $cmcApiGroupIds[] = [
                        'group_id' => $httpCmcApiGroupId,
                        'cmc_console_user_last_synced_at' => 0, //上次同步时间
                    ];
                    // 是否设置租户ID列表的缓存：是
                    $isSetRedisCacheGroupIds = true;
                }
            }
        }

        // 判断是否设置租户ID列表的缓存
        if ($isSetRedisCacheGroupIds) {
            // 将 $cmcApiGroupIds 存放到缓存供下次使用，将数据在缓存中永久保留
            $redisCache->set($redisCacheGroupIdsKey, $cmcApiGroupIds);
        }


        // 基于上次同步时间顺序排列，赋值给：$sortCmcApiGroupIds
        $sortCmcApiGroupIds = $cmcApiGroupIds;
        ArrayHelper::multisort($sortCmcApiGroupIds, 'cmc_console_user_last_synced_at', SORT_ASC);

        /* 判断 $groupId 是否为空，如果不为空 */
        if (!empty($groupId)) {
            // 销毁 $sortCmcApiGroupIds 中的 $groupId
            foreach ($sortCmcApiGroupIds as $sortCmcApiGroupIdKey => $sortCmcApiGroupId) {
                if ($sortCmcApiGroupId['group_id'] == $groupId) {
                    unset($sortCmcApiGroupIds[$sortCmcApiGroupIdKey]);
                    break;
                }
            }
            // 将 $groupId 插入至 $sortCmcApiGroupIds 的开头
            array_unshift($sortCmcApiGroupIds, [
                'group_id' => $groupId,
                'cmc_console_user_last_synced_at' => 0, //上次同步时间
            ]);
        }

            'update_time' => Yii::t('model/redis/cmc-console/user', 'Update Time'),
        ];
    }
}

3、查看 /common/components/redis/ActiveRecord.php ，定义了前缀，适用于所有 AR 键。

params['redisActiveRecord']['keyPrefix'] . parent::keyPrefix();
    }
}

4、打开 RedisDesktopManager，查看用户总数，确定为 29 个，如图2

图2

5、打开 RedisDesktopManager，确定主键值为 37918 的记录为 1 个，并未重复。如图3

图3

6、查看 pa:ar:user 的值，发现行 29、30 的值皆为 37918。由此确定，是此键的值导致了 id 等于 37918 的资源数等于 2 个。如图4

图4

7、删除 pa:ar:user 的第 30 行，如图5

图5

8、再次请求接口，响应参数中资源总数量为 29 个。包含 id 等于 37918 的资源未重复。仅剩下 1 个。

9、准备在本地环境复现一下 ID 主键重复的情况。请求接口，响应参数中资源总数量为 13 个。ID 主键未重复。如图6

10、在程序执行过程中，插入数据至 Redis 中时，会判断 ID 是否存在，存在则更新，不存在则插入。初步怀疑是在并发请求的情况下。皆执行了插入的操作。


            $redisCmcConsoleUser = new RedisCmcConsoleUser();

            }

            $redisCmcConsoleUserItem = $redisCmcConsoleUser::find()->where(['id' => $userInfo['id'], 'group_id' => Yii::$app->params['groupId']])->one();

            /* 如果资源不存在，则插入；否则更新 */

            }

11、在程序执行过程中，插入数据至 Redis 中时，不论 ID 是否存在，皆插入。请求接口，响应参数中资源总数量为 14 个。包含 id 等于 3 的资源是重复的。总计为 2 个。如图7

            if (!isset($redisCmcConsoleUserItem)) {
                $redisCmcConsoleUser->attributes = $redisCmcConsoleUserAttributes;
                $redisCmcConsoleUser->insert();
                // 设置用户身份为已认证
                Yii::$app->user->setIdentity($redisCmcConsoleUser);
            } else {
                $redisCmcConsoleUserItem->attributes = $redisCmcConsoleUserAttributes;
                $redisCmcConsoleUserItem->insert();
                // 设置用户身份为已认证

12、由此可以确认，Redis ActiveRecord 不能够确保主键 ID 的唯一性的。现阶段有 2 种方案，第 1 种方案是插入记录时基于 Redis 实现唯一性的锁定。第 2 种方案是查询时去重。决定采用第 2 种方案。由于 redis 不支持 SQL 查询，因此查询 API 仅限于以下方法： where()，limit()，offset()，orderBy() 和 indexBy()。 (orderBy() 尚未实现：#1305)。基于 indexBy()。请求接口，响应参数中资源总数量为 13 个。ID 主键未重复。但是，totalCount 的值为 14。统计错误。如图8

图8


        // 查询当前用户所属租户 ID 下的 CMC 的用户模型(Redis)
        $query = $modelClass::find()
            ->where([
                'group_id' => $identity->group_id,
                'is_open' => $modelClass::STATUS_ENABLED
            ])
            ->indexBy('id');


{
  "code": 10000,
  "message": "获取 CMC 用户列表成功",

    }
  }
}

13、因此，尝试采用第 1 种方案。不过由于此处程序实现是所有请求皆会执行到的流程，担心锁定实现降低程序性能，最终决定，放弃插入，仅做更新。如果 Redis 中用户不存在，则插入；否则更新。调整为：如果 Redis 中用户不存在，则响应 404；否则更新。


            /* 如果资源不存在，则响应 404 */
            if (!isset($redisCmcConsoleUserItem)) {
                throw new NotFoundHttpException(Yii::t('error', Yii::t('error', Yii::t('error', '201011'), ['user_nick' => $userInfo['user_nick']])), 201011);
            }

            /* 更新 */
            $redisCmcConsoleUserItem->attributes = $redisCmcConsoleUserAttributes;
            $redisCmcConsoleUserItem->save();
            // 设置用户身份为已认证
            Yii::$app->user->setIdentity($redisCmcConsoleUserItem);

14、如果 Redis 中用户不存在，则响应 404。如图9

图9

15、但是，此修复仅防止以后出现用户重复的问题，之前已经重复的用户，仍然是重复的。如果要去重，需要手动操作 Redis。且此修复会衍生出一个新的影响体验的问题，即在框架处新添加了一个用户 B 后，如果用户 B 在 Redis 中不存在，则用户 B 无法使用策划指挥。需要等待用户 B 同步至 Redis 后，才可使用。

在 Yii 2.0 中添加了多个 DB 应用组件时，Gii 的生成流程

永夜 — Wed, 20 May 2020 06:27:07 +0000

浏览量： 84

1、在 Yii 2.0 中添加了多个数据库连接组件时



    'components' => [
        'db' => [
            'class' => 'yii\db\Connection',
            'dsn' => 'mysql:host=62.234.135.47;dbname=pcs_api',
            'username' => 'sq_pcs',
            'password' => '',
            'tablePrefix' => 'pa_',
            'charset' => 'utf8mb4',
            'enableSchemaCache' => false,
            'schemaCacheDuration' => 3600,
            'schemaCache' => 'redisCache',
        ],
        'statDb' => [
            'class' => 'yii\db\Connection',
            'dsn' => 'mysql:host=62.234.135.47;dbname=pcs_stat',
            'username' => 'sq_pcs',
            'password' => '',
            'tablePrefix' => 'ps_',
            'charset' => 'utf8mb4',
        ],
    ],

2、数据库连接ID选择 statDb 时，表名的下拉列表中，仅会出现 statDb 下的数据表，如图1

图1

3、当生成 statDb 下的模型文件时，会额外生成 getDb() ，如图2

图2



    /** 
     * @return \yii\db\Connection the database connection used by this AR class. 
     */ 
    public static function getDb() 
    { 
        return Yii::$app->get('statDb'); 
    }

4、数据库连接ID选择 db 时，表名的下拉列表中，未出现 db 下的数据表，因此，需要手动填写相应的信息。如图3

图3

5、当生成 db 下的模型文件时，不会生成 getDb() ，因为 db 是默认的。如图4

图4

6、当 Preview 或者 Generate 后，数据库连接ID选择 db 时，表名的下拉列表中，仅会出现 db 下的数据表。如图5

6、决定分析测试 Nginx + php-fpm 在 Windows 10 下的串行表现。新建 phpinfo.php(延时 30 秒写入日志)、phpinfo1.php(延时 5 秒写入日志)，在浏览器中先打开 phpinfo.php、然后再迅速打开 phpinfo1.php，间隔时间约为 1 秒左右。 phpinfo.php

phpinfo1.php

7、在打开 phpinfo.php 后，其大约加载了 30 秒左右的时间长度。在打开 phpinfo1.php 后，其大约加载了 35 秒左右的时间长度(如果支持并行，则加载时间预计为 5 秒左右。如果不支持并行，仅支持串行，则加载时间预计为 35 秒左右，其中 30 秒为等待 phpinfo.php 运行结束的时间，只有当 phpinfo.php 运行结束后，9001 端口才可用，5 秒为 phpinfo1.php 自身运行的时间)。如图7

图7

8、分别查看生成的日志文件的创建时间。可以确定 phpinfo1.php 的日志文件的创建时间晚于 phpinfo.php 的日志文件的创建时间，精确为 5 秒钟。由此可以确定，Nginx + php-fpm 在 Windows 10 下，是仅支持串行请求的。如图8

图8

sleep-1-1585200359.txt

9、开发环境的部署方案为：CentOS + Nginx + php-fpm。重复第 6、7、8 步骤。分别查看生成的日志文件的创建时间。可以确定 phpinfo1.php 的日志文件的创建时间早于 phpinfo.php 的日志文件的创建时间，精确为 23 秒钟，虽然其晚于 phpinfo.php 开始运行。由此可以确定，Nginx + php-fpm 在 CentOS 7 下，是支持并行请求的。如图9

图9



sleep-0-1585202045.txt
sleep-1-1585202022.txt

10、编辑 Nginx 配置文件，修改 server_name 的值：api.channel-pub.wjdev.chinamcloud.cn localhost，以在一个请求(https://api.channel-pub.wjdev.chinamcloud.cn)中 CURL 另一个请求(http://localhost)(总计请求次数为 7)，直接请求本机，以节省网络开销。其总体响应时间长度为：1956ms，2 秒左右，符合预期。如图10

图10

11、直接请求本机，其并发请求数受限于 php-fpm.conf 中的 pm.max_children 值。现在默认设置为：40。子进程的数量固定为 40 个。当在一个请求(https://api.channel-pub.wjdev.chinamcloud.cn)中 CURL 另一个请求(http://localhost)的数量为 52 时，其总体响应时间长度为：6.00s。如图11

图11

12、当请求数量为 42 时，其总体响应时间长度为：4.73s。当请求数量为 35 时，其总体响应时间长度为：4.39s。当请求数量为 30 时，其总体响应时间长度为：3.79s。当请求数量为 25 时，其总体响应时间长度为：2.98s。当请求数量为 20 时，其总体响应时间长度为：2.85s。当请求数量为 15 时，其总体响应时间长度为：2.36s。当请求数量为 10 时，其总体响应时间长度为：2.21s。 13、在服务器上 curl，查看 php-fpm 的状态页。



[root@5b9088596e62 /]# curl http://127.0.0.1/status
pool:                 www
process manager:      static
start time:           26/Mar/2020:13:50:05 +0800

active processes:     1
total processes:      40
max active processes: 10
max children reached: 0
slow requests:        0

14、最后分析测试的结果： Windows + Nginx + php-fpm(串行)、CentOS + Nginx + php-fpm(并行)、MacOS + Nginx + php-fpm(并行)、MacOS + Apache(并行)。

基于 Composer 安装：JamesHeinrich / getID3，提示 ( SSL：握手超时；无法启用加密；无法打开流：操作失败 ) 的解决

在 Rancher 中实现集群的部署与测试 ( 负载均衡与命令行下的 Redis 锁定、性能提升 )

永夜 — Mon, 09 Mar 2020 02:10:11 +0000

浏览量： 92

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

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

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

5、此时，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 60 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

                    break;
                }
            }

            // 将 $cmcApiGroupIds 存放到缓存供下次使用，将数据在缓存中永久保留
            sleep(8);
            $redisCache->set($redisCacheGroupIdsKey, $cmcApiGroupIds);

            // 释放锁定
            $redisLock->unlock($redisLockKeyName);

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

            [cmc_console_user_last_synced_at] => 0
        )

)

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

            // 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)。

在 Yii 2.0 中，唯一性验证失败时，提示不够友好，自动调整优化的分析

1、测试人员提交了一个 Bug，认为唯一性验证失败时，提示不够友好(中英文混杂，用户不易理解)，提示信息如图1

图1

2、在本地环境的最新版本中，准备复现时，意外发现提示信息已经全部显示为中文，提示信息如图2

图2



{
    "code": 226004,
    "message": "数据验证失败：租户ID, 栏目名称, 是否被删除 与 删除时间 的值 \"\"015ce30b116ce86058fa6ab4fea4ac63\"-\"深圳市9\"-\"0\"-\"0\"\" 已经被占用了。"
}

3、查看相应程序文件，并未针对提示信息做相应调整，查看 Git 日志，提交：通过运行 composer update 来更新 Yii 2 至最新版本，已将 Yii Framework 从 2.0.15.1 版本升级到 2.0.31。初步怀疑是由于 Yii 框架版本的升级，进而调整了提示信息。如图3

图3

4、部署标签：1.10.4-alpha.5，为升级前的版本，Bug 已复现，如图4

图4



{
    "code": 226004,
    "message": "数据验证失败：The combination \"015ce30b116ce86058fa6ab4fea4ac63\"-\"深圳市1\"-\"0\"-\"0\" of 租户ID, 栏目名称, 是否被删除 and 删除时间 has already been taken."
}

5、部署标签：1.10.4-alpha.6，为升级后的版本，Bug 已修复，英文已经消失，提示信息更友好，如图5

图5



{
    "code": 226004,
    "message": "数据验证失败：租户ID, 栏目名称, 是否被删除 与 删除时间 的值 \"\"015ce30b116ce86058fa6ab4fea4ac63\"-\"深圳市1\"-\"0\"-\"0\"\" 已经被占用了。"
}

6、由此得出结论，唯一性验证失败时，提示更友好的缘故在于，已将 Yii Framework 从 2.0.15.1 版本升级到 2.0.31。究竟是期间的哪个版本导致的，查看 /vendor/yiisoft/yii2/messages/zh-CN/yii.php 的 Github 日志。参考网址：https://github.com/yiisoft/yii2/commit/b8a3fa4ff96cb80d77fcf8003163c9001770ae8b#diff-9083c63f8544587712f4083785a317cf ，在提交：b8a3fa 中，新增加了一行。提交于 2018年4月5日，如图6

图6



    'The combination {values} of {attributes} has already been taken.' => '{attributes} 的值 "{values}" 已经被占用了。',

7、参考网址：https://github.com/yiisoft/yii2/tree/2.0.16/framework/messages/zh-CN ，提交：b8a3fa 存在于 Tag：2.0.16 中。因此，可以确定 Yii Framework 的 2.0.16 版本，已经优化了相应提示信息。如图7
