从鸟山明到 MySQL 5.7 EOL (升级到 8.0)

从鸟山明到 MySQL 5.7 EOL (升级到 8.0)

ShawnYan Lv.6

鸟山明,这个名字代表着无限的想象力和创造力。他的《龙珠》不仅是一部漫画,更是一种文化现象。

今天,我们将从这部经典作品出发,讨论一个看似不相关的主题:MySQL 5.7的生命周期结束。

鸟山明与《龙珠》

鸟山明,这个名字对于许多人来说,是童年的记忆,是英雄主义的象征。

他的作品《龙珠》不仅塑造了一个充满奇幻和冒险的世界,更激发了无数人对超越自我的渴望。

记得孙悟空与弗利萨的决战吗?那是一场关于力量、智慧和勇气的较量,也是一次关于不断突破极限的挑战。

MySQL 5.7 EOL

现在,让我们从赛亚人的战斗场景转向数据库的世界。

MySQL,作为全球最受欢迎的开源数据库之一,它的每一次更新都牵动着无数开发者的心。

2023年,MySQL 5.7宣布了生命周期结束(EOL),这意味着官方不再提供安全更新和技术支持。

对于依赖这个版本的开发者来说,这无疑是一个重大的转折点。

MySQL 5.7 EOL 的影响

对于开发者来说,MySQL 5.7 EOL 不仅仅是一个结束,更是一个新的开始。

它意味着我们必须考虑迁移到新版本,但这也是一个提升系统性能和安全性的机会。

比如使用更新的硬件、 OS 系统,以及新版本的生态工具。

就像孙悟空不断突破自我极限一样,开发者也需要不断创新,不断学习,以适应技术的发展。

再见 MySQL 5.7,升级到 MySQL 8.0

或许是时候跟 MySQL 5.7 说再见了,下面使用 RPM 方式进行版本升级。

连接到数据库,并写入测试数据。

下载 MySQL 8.0 安装包,注意选择对应操作系统。

比如,MySQL 5.7 安装在 CentOS 7 上,MySQL 8.0 的包需要选择 Red Hat Enterprise Linux 7。

解压并安装 RPM 包。

带来的挑战

4 月 30 日,MySQL 的第一个 LTS 版本 8.4.0 发布,MySQL 9.0 创新版本也计划于今年三季度发版。

84.png

(关于 MySQL 8.4 的消息,请参考:快讯! MySQL 8.4.0 LTS 发布(MySQL 第一个长期支持版本))

值得注意的是,我们无法从 MySQL 5.7 直接升级到 MySQL 8.4,必须要先升级到 8.0。

Important Change: Upgrading from MySQL 5.7 to MySQL 8.4 is not supported; the code and behavior was updated to reflect this. Upgrade MySQL 5.7 to 8.0 before proceeding to 8.4. (WL #15924)

对此,建议各位从业者关注 MySQL 8.4 的发版动态,包括新特性和兼容性方面的内容,

并考虑将现有的 MySQL 5.7 服务器择机升级到 8.0 版本,以应对未来的变化。
