前言
最近由于等保相关问题以及本地开发的需要，需同时安装多个版本的MySQL，因此只能根据zip进行手动安装，期间遇到一些问题，在此记录一下。
手动安装过程
- 首先从官网下载zip格式的压缩包，并解压到向安装的目录
在安装目录新建一个my.ini配置文件，文件内容如下，大部分是默认配置(log相关名称已改)，可按自己需要修改。

Permitted values are TempTable (the default) and MEMORY. internal_tmp_mem_storage_engine=TempTable #*** MyISAM Specific options # The maximum size of the temporary file that MySQL is permitted to use while re-creating a # MyISAM index (during REPAIR TABLE, ALTER TABLE, or LOAD DATA).

Value 0 means that the log is only written to the log file and # the log file flushed to disk approximately once per second. Value 2 # means the log is written to the log file at each commit, but the log # file is only flushed to disk approximately once per second. innodb_flush_log_at_trx_commit=1 # The size in bytes of the buffer that InnoDB uses to write to the log files on # disk. The default value changed from 8MB to 16MB with the introduction of 32KB # and 64KB innodb_page_size values.

The default value is 134217728 bytes (128MB).

mysqld.exe --defaults-file=D:\dev\mysql\my.ini --initialize --console- 如果当前环境变量中已有其它mysqld环境变量，可以通过增加全路径来执行，防止因为环境变量原因使用了其它路径上的mysqld。
没有错误的话则可以安装为服务了，如果执行初始化成功，服务器启动失败，确认一下是否是因为mysqld环境变量的原因，解决方式同上，命令如下：
# 最好使用全路径，防止其它的mysqld环境变量 d:\dev\mysql\bin\mysqld.exe --install MySQL --defaults-file=D:\dev\mysql\my.ini- 还有一种服务起不来的情况可能是因为缺少Uploads目录，需要手动创建该目录，目录具体位置参考配置项：secure-file-priv
- 如果服务还是启动失败可以在命令行中执行上面的命令，然后根据错误排查原因。
结论
通过以上步骤大概率就安装成功了，适合需要安装多个版本的情况，完结撒花🌸🌸🌸
