如何在Debian linux中禁用访问时间设置

MongoDB的性能最佳实践意味着：

Most file systems will maintain metadata for the last time a file was
accessed. While this may be useful for some applications, in a
database it means that the file system will issue a write every time
the database accesses a page, which will negatively impact the
performance and throughput of the system.

对于mongoDB安装,我需要在我的Debian上禁用访问时间,该怎么做？

解决方法:

要禁用写入访问时间,您需要使用noatime选项挂载有问题的文件系统.

要使用noatime选项挂载已安装的文件系统,请执行以下操作：

mount /home -o remount,noatime

要使更改成为永久更改,请更新/ etc / fstab并将noatime添加到选项字段.

例如.

之前：

/dev/mapper/sys-home  /home  xfs  nodev,nosuid         0       2

后：

/dev/mapper/sys-home  /home  xfs  nodev,nosuid,noatime  0       2
