Windows MySQL5.5 搭建3307多实例从库（避坑完整版）一、环境准备系统：Windows10数据库版本：MySQL5.5原有实例：3306主库新建实例：3307从库二、完整操作步骤1. 复制独立程序目录复制原安装目录：C:\Program Files (x86)\MySQL\MySQL Server 5.5 → 改名 MySQL Server 5.5_3307复制原数据目录：C:\ProgramData\MySQL\MySQL Server 5.5\Data → 改名 MySQL Server 5.5_3307\Data核心要点：两个实例目录完全分离，不能共用文件夹。2. 编写独立my.ini配置文件在3307程序根目录新建my.ini（必须使用该文件名），只需要改端口号、路径，内容如下：# MySQL Server Instance Configuration File # ---------------------------------------------------------------------- # Generated by the MySQL Server Instance Configuration Wizard # # # Installation Instructions # ---------------------------------------------------------------------- # # On Linux you can copy this file to /etc/my.cnf to set global options, # mysql-data-dir/my.cnf to set server-specific options # (@localstatedir@ for this installation) or to # ~/.my.cnf to set user-specific options. # # On Windows you should keep this file in the installation directory # of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To # make sure the server reads the config file use the startup option # "--defaults-file". # # To run run the server from the command line, execute this in a # command line shell, e.g. # mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini" # # To install the server as a Windows service manually, execute this in a # command line shell, e.g. # mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini" # # And then execute this in a command line shell to start the server, e.g. # net start MySQLXY # # # Guildlines for editing this file # ---------------------------------------------------------------------- # # In this file, you can use all long options that the program supports. # If you want to know the options a program supports, start the program # with the "--help" option. # # More detailed information about the individual options can also be # found in the manual. # # #
