我有cron3min.php，cron10min.php，cron60min.php。
我正在使用PDO。
cron3min.php很忙，每3分钟一次
每3分钟就有大约50.000 - 500.000行，所以当来自cron的其他请求到来时，通常第一个cron请求没有完成。
当我从catch检查我的错误日志时，我看到：

在cron3min.php中有这个函数：
$provider->getOdds();
$xmldb->sendOddsToDb();
$xmldb->sendFixturesToDb();
$xmldb->fillBaby();
$topOdds->insertTopOdds();
$xmldb->copyHAtoHandicap();
$con->close();
最繁忙的功能是$xmldb->sendOddsToDb();和$xmldb->copyHAtoHandicap();
我将在这里复制$ xmldb-＆gt; sendOddsToDb（）;,在每个函数中我启动事务并在函数结束时提交并关闭。
这里是sendOddsToDb（）并请检查它，看看只是一个mysql逻辑，有什么不对，我的开始交易是好的吗？ Xml解析需要大约1：30-2分钟（大部分时间需要代码的3路部分，我需要在数组中存储障碍），所以也许是打开长连接或者其他东西......

答案 0 :(得分：1)
因为您在错误日志中遇到某些查询尝试锁定记录而其他查询已经通过锁定使用它。可能有多种原因，因此请尝试与他们核对并解决问题。
第一步：
当你在帖子中更新cron花费超过3分钟并且下一轮开始时，可能是第一次cron正在使用某些记录而第二次cron也试图锁定它。
但是，只有当您的查询没有正确使用索引并尝试锁定比预期更多的记录时，它才会出现。因此，如果可以优化，请检查您的查询。
第二步：
可能是某个其他进程也试图锁定此cron正在执行的行，因此检查引擎innodb状态中的详细信息，表明哪个进程正在创建死锁。
您还可以通过任何gui工具监控，例如mysqladmin在此cron时尝试获取锁定的查询，并优化查询/代码。
