NAME
|
|||
|
Apache::Session::Memorycached - An implementation of Apache::Session
|
|||
|
|
|||
|
SYNOPSIS
|
|||
|
use Apache::Session::Memorycached;
|
|||
|
|
|||
|
tie %session, 'Apache::Session::Memorycached', $cookie, {
|
|||
|
'servers' => ["10.75.1.19:11211"], #all write operations
|
|||
|
'local' => ["localhost:11211"], #read-only operations
|
|||
|
'timeout' => '300'
|
|||
|
};
|
|||
|
|
|||
|
tie %s, 'Apache::Session::Memorycached', undef,
|
|||
|
{servers => ['mymemcachedserver:port'],
|
|||
|
'timeout' => '300',
|
|||
|
'updateOnly' => 1 ,
|
|||
|
'principal' => uid,
|
|||
|
};
|
|||
|
|
|||
|
In order to optimize the network ,you can use a local memcached server.
|
|||
|
All read-only op<6F>ration are sending fisrt at local server .If you need
|
|||
|
write ou rewrite data , the data is sending at the principal memcached
|
|||
|
sever and local cache too for synchronisation.
|
|||
|
|
|||
|
note : 'updateOnly' => 1 just realize up-date operation not init
|
|||
|
operation. Init operation is use in order to book and lock the number
|
|||
|
session but it's not available in this module
|
|||
|
|
|||
|
'principal' => uid : this parameter is use to create reverse reference
|
|||
|
like this : MD5_hex(uid) => id_session in memcached server . By this it usefull to retrieve id_session from principal name . And add uid_MD5 => MD5_hex(uid) in main session .
|
|||
|
|
|||
|
DESCRIPTION
|
|||
|
This module is an implementation of Apache::Session. It uses the
|
|||
|
memcached system backing store . You may specify servers (principal) and
|
|||
|
locals caches for locking in arguments to the constructor. See the
|
|||
|
example, and the documentation for Apache::Session::Store::Memorycached
|
|||
|
and Cache::Memcached .
|
|||
|
|
|||
|
REPLICATION
|
|||
|
Now Apache::Session::Memorycahed inclues replication between memecached servers
|
|||
|
Two new components provide a replication service .
|
|||
|
First package is Apache::Session::MemcachedReplicator
|
|||
|
Second is Apache::Session::MemcachedClient
|
|||
|
|
|||
|
It's now possible to do replication master to slave or master to master
|
|||
|
see man pages and scripts .
|
|||
|
|
|||
|
SOAP service
|
|||
|
Now Apache::Session::Memorycached inclues a SOAP service in order to set or
|
|||
|
get %session in any language . The SOAP service translates data in Perl hashes
|
|||
|
|
|||
|
Installation of SOAP service
|
|||
|
All scripts are in scripts directory
|
|||
|
|
|||
|
Put MemcachedSOAPClass.pm and MemcachedSOAP.cgi in the cgi-bin directory of your apache server with the appropriate right (x) .
|
|||
|
Change in MemcachedSOAP.cgi the memcached server address .
|
|||
|
(line 11 : $machine = 'ip.ip.ip.ip:11211'; )
|
|||
|
|
|||
|
Try the three scripts statTest.pl (first !) then getTest.pl finish with setTest.pl.
