ubuntu - mysqld 在运行简单查询时收到信号 6

问题描述

我已经开始让mysql崩溃并重新启动。系统已经完全稳定，这在创建下表后开始发生。我使用INSERT INTO命令成功插入了大约 210,000 条记录。但后来我注意到在运行简单的和INSERT命令时服务器出现故障。UPDATESELECT

例如，当我运行以下查询时服务器崩溃了：SELECT * FROM tipstrade_2.tblVehicleLookups limit 1

任何识别问题的提示将不胜感激。

CREATE TABLE `tblVehicleLookups` (
  `fldID` int(11) NOT NULL AUTO_INCREMENT,
  `fldTicketID` char(12) NOT NULL,
  `fldVRM` varchar(10) NOT NULL,
  `fldVIN` char(17) NOT NULL,
  `fldMake` varchar(32) NOT NULL,
  `fldModel` varchar(32) NOT NULL,
  `fldVehicle` varchar(255) NOT NULL,
  `fldDiscriminator` varchar(255) NOT NULL,
  `fldData` text NOT NULL,
  `fldPrice` decimal(5,2) DEFAULT NULL,
  `fldFreeAfter` date NOT NULL DEFAULT '0001-01-01',
  `fldIsFree` bit(1) GENERATED ALWAYS AS (`fldFreeAfter` < cast(current_timestamp() as date)) VIRTUAL,
  `fldCreated` datetime NOT NULL DEFAULT current_timestamp(),
  `fldModified` datetime DEFAULT NULL ON UPDATE current_timestamp(),
  `fldCarWebID` int(11) DEFAULT NULL,
  PRIMARY KEY (`fldID`),
  UNIQUE KEY `fldCarWebID` (`fldCarWebID`),
  KEY `fldVRM` (`fldVRM`),
  KEY `fldVIN` (`fldVIN`)

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed, 
something is definitely wrong and this may fail.

Server version: 10.2.36-MariaDB-10.2.36+maria~xenial-log
key_buffer_size=1073741824
read_buffer_size=2097152
max_used_connections=152
max_threads=202
thread_count=153
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2087104 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

解决方案

我从来没有深究这一点。最后我咬紧牙关，从 10.2 -> 10.3 -> 10.4 -> 10.5 升级，确保我mysql_upgrade在每次更新之间运行（以及数据目录的完整备份mysql，这很方便！）。

从那时起，我一直在愉快地阅读、插入、更新和删除有问题的表中的数十万条记录，并且数据库没有跳过一个节拍。

我唯一的解释是：

  1. 警告“这可能是因为您遇到了错误。也可能是此二进制文件或其链接的库之一已损坏、构建不正确或配置错误。” 是正确的，升级服务器和依赖项解决了这个问题。
  2. 有表损坏，并mysql_upgrade解决了这个问题。

我已经排除了硬件错误，因为它又可以正常工作了。国际劳工组织也没有给我任何警告。
