Waiting for master update:连接到主库之前的初始状态 Waiting for slave mutex on exit:线程停止时短暂发生的状态,表示正在回收 I/O 线程的相关互斥资源 Waiting for the slave SQL thread to free enough relay log space:如果 relay_log_space_limit 变量设置值不为 0,那么当中继日志总大小增长到超过此值时。
如果Event的状态为’Locked’,表示Event正在等待其他操作完成。如果Event的状态为’Waiting for next activation’,表示Event已经执行完成。 如果Event的执行结果报错,可以通过查看Mysql的错误日志来获取错误信息。可以使用以下SQL语句查看Mysql错误日志的路径: SHOWVARIABLESLIKE'log_error'; 1. 4. 总结 通过以上步骤,我们...
