mac mysql为啥提示无权限修改配置文件

Posted 2023-03-20

参考技术A 1、查找my.ini位置，可通过windows服务所对应mysql启动项，查看其对应属性->可执行文件路径，获取my.ini路径。　　"D:\MySQL\MySQLServer5.5\bin\mysqld"--defaults-file="D:\MySQLData\my.ini"MySQL552、编辑my.ini中对应datadir　　改前：datadir="D:\MySQLData\data\"　　改后：datadir="D:\MySQLData\MySQLServer5.5\data\"3、重整mysql对应数据文件目录（若不做，则mysql无法正常启动）4、查找注册表，修改mysql启动项所关联的defaults-file路径：　　KEY_LOCAL_MACHINE/SYSTEM/Services/MySQL55　　修改完后，刷新windows服务，再次查看mysql启动项属性->可执行文件路径，结果如下：　　"D:\MySQL\MySQLServer5.5\bin\mysqld"--defaults-file="D:\MySQLData\MySQLServer5.5\my.ini"MySQL　　确保将my.ini移植到正确的目录下。5、重启mysql，配置成功。
