步骤

1. 找到mysql的配置文件 “my.ini”，
   windows上直接进入mysql安装目录，或者直接全盘搜；
   linux上使用命令 locate my.ini 即可搜索
    
2. 修改"my.ini"，找到 组[mysqld] 下面的“log_error=”并设置日志文件绝对路径，
   如果找不到，就在 组[mysqld] 下新增一行，例如：

   [mysqld]
   port=3306
   ...
   log_error=E:/phpStudy/Extensions/MySQL5.7.26/log/error.log

3. 重启mysql即可 看到日志文件
