这个问题确实是服务器系统盘满了,mysql指定的临时文件目录满掉,大概就是这个意思. 下面解决/dev/vda1系统盘满了,其实我压根不知道/dev/vda1这在哪,是什么,后来了解这是 virtio-block 类型的设备。 科普一下: 以‘c’ 开头的一行表示该设备是一个字符设备,以‘b’ 开头的行表示这是一个块设备。 /dev/vda ...

default-storage-engine 是 MySQL 数据库的一个配置选项,用于设置默认的存储引擎。MyISAM 是一种基于表的存储引擎,是 MySQL 5.5 版本及之前版本的默认存储引擎,提供了较高的性能和可靠性,但不支持事务和行级锁定等高级功能。 设置default-storage-engine=MyISAM,意味着在创建新表时,如果没有指定使用其他存储引擎,My...
storage engine, and the one that is most widely used. InnoDB is ACID (Atomicity, Consistency, Isolation, Durability) compliant, designed for short transactions that are normally committed, rather than being rolled back. It's a reliable, general purpose storage engine that works well for m...
MySQL Server uses a pluggable storage engine architecture that enables storage engines to be loaded into and unloaded from a running MySQL server. To determine which storage engines your server supports, use theSHOW ENGINESstatement. The value in theSupportcolumn indicates whether an engine can be ...
虽然TYPE仍然在MySQL 5.1中被支持,现在ENGINE是首选的术语。 如果你省略掉ENGINE或TYPE选项,默认的存储引擎被使用。一般的默认是MyISAM,但你可以用--default-storage-engine或--default-table-type服务器启动选项来改变它,或者通过设置storage_engine或table_type系统变量来改变。
The WiredTiger storage engine is the default storage engine. For existing deployments, if you do not specify the--storageEngineor thestorage.enginesetting, themongodinstance can automatically determine the storage engine used to create the data files in the--dbpathorstorage.dbPath. ...
