![在安装MySQL服务的时候，报错：mysql: [ERROR] Found option without preceding group in config filexx_MySQL](https://s2.51cto.com/images/blog/202507/05002034_6867ff52e8c84130.png?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_30,g_se,x_10,y_10,shadow_20,type_ZmFuZ3poZW5naGVpdGk=/resize,m_fixed,w_1184 "在这里插入图片描述")
一、报错原因
如果该文件是 UTF-8 编码，带有 BOM（Byte Order Mark）头部，MySQL 会识别失败，从而把 BOM 当成非法字符
二、解决办法
![在安装MySQL服务的时候，报错：mysql: [ERROR] Found option without preceding group in config filexx_MySQL_02](https://s2.51cto.com/images/blog/202507/05002035_6867ff5339a0692613.png?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_30,g_se,x_10,y_10,shadow_20,type_ZmFuZ3poZW5naGVpdGk=/resize,m_fixed,w_1184 "在这里插入图片描述")
按照以上操作完成之后，重新注册服务即可。如果成功，不会再报 [ERROR] Found option without preceding group 错误。
mysqld --install
