安装Mysql8.0.13
配置文件
找到原来安装目录的 .ini文件, Mysql服务启动时候会读取 .ini配置文件
将my-default.ini文件复制到新下载的压缩包中,为了沿用原来数据库的数据,在这里只修改 basedir, 其它的保持不变
.ini文件如下
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

配置环境变量
使用管理员权限安装
D:\DataBase\MySQL\mysql-8.0.13-winx64\bin>mysqld install
Service successfully installed.
启动服务
登录Mysql查看数据
数据也过来了,注意,原来的data目录不能删除。如果想删除,可以把data文件夹复制到mysql8.0.13
目录下,修改.ini文件的datadir路径
