MySQL运维实战（1.3）安装部署：源码编译安装

作者：俊达

引言

在大多数情况下，我们不需要自己编译MySQL源码，因为编译的MySQL和二进制包的内容基本一致。然而，有些特殊情况可能需要我们采用源码编译的方式安装MySQL：

• 安装非标准版本的MySQL：有些特殊的应用场景会使用到MySQL的非标准版本，这时候我们就需要编译源码来安装。
• 安装社区的patch、bugfix、扩展插件：通过源码编译，可以轻松地添加社区提供的补丁、修复程序和扩展插件，以满足特定需求。
• 禁用二进制版本中的某些特性：源码编译可以让用户选择禁用或启用某些特定功能，以满足自己的需求。
• 使用未编译的功能：有些功能可能在二进制版本中并没有被编译进去，而通过源码编译可以启用这些功能。
• 使用其他编译器优化插件：源码编译可以让用户选择使用其他编译器进行编译，或者进行一些个性化的优化设置。例如，如果我们想要使用Intel的C编译器。
• 链接一些其他基础库：源码编译可以允许用户链接其他基础库，例如使用tcmalloc等。
• 编译debug版本：通过源码编译可以生成debug版本的MySQL，用于调试和分析问题。

因此，了解MySQL源码编译安装对于学习MySQL运维来说，确实是非常有帮助的。这不仅可以帮助我们更好地理解MySQL的工作原理，还可以让我们在面对一些特殊需求时，能够更加灵活地处理。

4 初始化数据库 & 启动MySQL

初始化数据库和启动MySQL的步骤和上一篇二进制安装方式一样（MySQL运维实战（1.2）安装部署：使用二进制安装部署），这里不再重复。
