排列三开机号公益时报中华彩票网:MySQL/MariaDB/Percona数据库升级脚本

发布时间:2017-12-13   编辑:排列三开机号 www.f7ct.cn
jquery中文网为您提供MySQL/MariaDB/Percona数据库升级脚本等资源,欢迎您收藏本站,我们将为您提供最新的MySQL/MariaDB/Percona数据库升级脚本资源
MySQL/MariaDB/Percona数据库都是我们常用的数据库了,特别是mysql在linux或windows中使用到是非常的多了,今天我们来看这三种数据库在linux中的升级脚本

排列三开机号 www.f7ct.cn 一般情况下不建议升级数据库版本,该脚本专提供给各位版本控们。为防止大版本之间兼容问题,脚本默认仅支持同一大版本之间的升级,如:MySQL-5.6.25升级到MySQL-5.6.26、MySQL-5.5.44升级到MySQL-5.5.45、MariaDB-10.0.20升级到MariaDB-10.0.21;不能跨分支版本且不能跨大版本,如从MySQL-5.5.44升级到PerconaL-5.5.44-37.3、MySQL-5.5.44升级到MySQL-5.6.25。
