PHP文件上的互斥锁（锁定文件）

Question

hi guys i searched a lot but i get stocked on this one

i have a Mutex class witch basically is using flock and it will lock a file just fine but my script is running over about 200~ above users so because of this my Server Hard Drive will always working a lot and this is very expensive for my work so i need a very simple solution to lock a file like flock but not touching the HDD .

i tested PECL extention ( i dont know this will fixed my problem either ) but its really hard to config and use it.

thanks in advance and sorry for my bad English

Answer 1

You could set up a ram drive under both Linux and Windows and store your lock files there. I have a similar system and since they are so small (empty files so only file meta data) even a few megabytes can store quite a lot of them. Another upside with this is that a system reboot will delete all lockfile's so no lingering ones are left on the drive.

On Linux you could add something like the following to /etc/fstab

tmpfs       /mnt/ramdisk tmpfs   nodev,nosuid,noexec,nodiratime,size=1024M   0 0

On Windows you can download something like ImDisk Toolkit and create a ramdisk with that.
