Windows2003 more and more slowly solutions may be too much with temp/sess_ junk files

Now can only be manually cleaned and divided into multi-level directory storage. At least I can mitigate I/O pressure. The following method allows you to schedule tasks with the system. Run it once a week. Empty cookies seven days ago

First, use PHP to automatically create a two-level directory such as this sort of directory/1/b/or A/1/, which is cached in numbers and letters. PHP statements are as follows

The code is as follows

Copy Code

<?php Error_reporting (E_all & ~e_notice); $string = ' 0123456789abcdefghijklmnopqrstuvwxyz '; $length = strlen ($string); for ($i = 0; $i < $length; $i + +) { for ($j = 0; $j < $length; $j + +) {createfolder (' d:/pc_webserver/phproot/v8/data/'. $string [$i]. ' /'. $string [$j]); } } function CreateFolder ($path) { if (!file_exists ($path)) { CreateFolder (DirName ($path)); Back to the directory section in the path mkdir ($path, 0777); } } ?>

Then, modify the php.ini file on the server. Search for the word session.save_path

Modified to Session.save_path = "2;d:/tmp/sess"

This means that the session cache is placed in the Level 2 directory in the tmp/sess directory of D disk. Then you copy the multilevel directories generated by the above files to the d:/tmp/sess, and finally form a directory structure like this

d:/tmp/sess/m/5/

Then the sess is automatically generated in the inside. Of course, the system will not be able to automatically clean up this junk file after this classification. It's manual.

The code is as follows	Copy Code
@echo off Echo is purging files, please wait ... Echo y| forfiles/p d:/tmp/sess/s/d-7/C "cmd/c del @path" echo clearance System, LJ, complete!

Copy the above contents in txt Notepad to save. and modify the suffix to. bat, and run the scheduled task. The meaning of this sentence is to search d:/tmp/sess this directory, echo y|, to indicate that when you confirm, the command directly selects yes./s to include all subdirectories, d-7 represents the file 7 days ago. ,/C indicates the command to execute, with double quotes, and Del to clear the previous directory. If you add a m/as the following sentence, it means that only files with a rar suffix are deleted. Otherwise, delete all.

The code is as follows	Copy Code
Echo y| forfiles/p d:/tmp/sess/s/M *.rar/d -7/c "cmd/c del @path"

Here is an explanation given in the php.ini

After this number of seconds, the stored data will be treated as "garbage",
Clean up the garbage collection process.
session.gc_maxlifetime = 1440

Note: If you are using subdirectory options for storing session files
(see session.save_path above), then garbage collection does not * * *
occurs automatically. You will need to do your own garbage
collection, through a shell script, cron item, or some other method.
For example, the following script will be equivalent to
set Session.gc_maxlifetime 1440 (1440 seconds = 24 minutes):
CD/path//section; Find Cmin +24 | Xargs rm
