MySQL初始化失败报错mysqld: Can't create/write to file '/data_backup/mysql/data/is_writable' (Errcode: 13 - Permission denied)

 

除了检查目录空间，目录权限，所属用户及所属组外（这些网上大把）

 

最近有个需求将数据目录/mysql/data/挂载到腾讯云的文件存储CFS目录下，但初始化出现上面的报错

#解决办法

最后找腾讯技术支持，也搞了大半天，最后将/data_backup/mysql/data/的/data目录删了，让初始化时自动创建，然而竟然成功初始化

 

疑点：为什么在本地的盘以及阿里云的文件储存NAS上创建/data/目录，初始化是可以的，而腾讯云文件储存就有问题，暂时找不到原因

期间我也直接切换到MySQL用户，用MySQL用户去初始化，但如果/data/数据目录在，初始化还是上面的报错；或许这也是个坑，记录一下
