LXXII. Mohawk Software セッションハンドラ関数

導入

msession は、ローカルまたはリモートで実行される高速セッションデーモンへのインターフェイスです。複数のPHP Webサーバにおいて集中的なセッション管理を行うために設計されています。 msessionとセッションサーバソフトウエアに関するより詳細な情報は、にあります。

注意: この拡張モジュールはWindows環境では利用できません。

要件

インストール手順

PHPでMsessionサポートを有効にするには、 --with-msession[=DIR]をconfigureに指定して下さい。ただし、DIRはMsessionのインストールディレクトリです。

A company I work for uses msession for a large cluster of servers.  I've set it up rather regularly and never had an issue at all with it not working.



Msession is stable.  It does something simple- it maintains an efficient database of key->value (session->data) pairs and searches them well in a nice threaded manner.  There is no need for constant revision.  It is _NOT_ a large application.  It's security is simply IP-block-based, so such concerns are also minimal.



To the user that says it should be removed- if you are having problems installing it, seek assistance doing so.  The product itself is just right.

Do NOT use msession!!! On the lates distributions (Redhat, Suse) the msessions won't work anymore: the daemon won't fork at startup time and stucks after called once. I've tested this on three systems (e.g. SuSE 9.1.). Furthermore, the msessiond package is NOT supported/maintained since years. i recommend to remove it from the offical php distribution. Norbert.

We've created a distributed session handler that uses memcached - Check it out at  - It's free and open source!

It uses Danga.com's memcached:  - Very cool stuff!

Compiling msession can be quite a pain. Believe me. 



Here's how I did it on a gentoo-box with gcc version 3.3.4 (20040623 (Gentoo Linux 3.3.4-r1, ssp-3.3.2-2, pie-8.7.6)):



1. Download  and 

2. Extract them in /usr/local (That path is hardcoded, so you don't really have a choice since there isn't a configure script)

3. You should now the directory /usr/local/phoenix containing msession and src.

4. Enter the src-directory and rename Linux.mak to config.mak (or the corresponding file, if you're using another system. Don't use unixgcc.mak directly - it won't work.).

5. Type make

6. Type make install. You might have to create /usr/local/phoenix/lib yourself and then type make install again.

7. Change into the msession-directory and type make.



For both msession and phoenix you may have to edit the makefiles manually and comment out the postgreesql and odbc-code (if you don't have postgree installed).



8. Recompile php with --with-msession.



Voil�!

msession 1.0 (020603) is using /dev/urandom.

You can fix the no random data in FreeBSD's /dev/random by using rndcontrol (as root) and setting the interupts which it looks at for entropy.



Something like  rndcontrol -s 14 -s 15  should help it out.

If you have trouble connecting to the msessiond from a php-script, this might be the solution for you.



msessiond (and your php-extension) both use the libphoenix.a which, among other files, is built from a file called "mutils.cpp".



Open this file, and find a line saying:



FILE *f = fopen("/dev/random", "rb");



(I believe it is line 506. There's only this one.)



On my FreeBSD 4.5 Tiny, /dev/random seldom spits out data, so the program hangs on the next line (an fread() call). Use /dev/urandom instead, it always sends data.



Change the line above to:



FILE *f = fopen("/dev/urandom", "rb");



Then rebuild phoenix-lib, msessiond, and PHP. You might want to do a "make clean" to be sure the change is noted.
