130524 discuz x2.0 关于 memcache得应用

让discuz支持多组memcache

discuz 是不支持多组memcache 共同使用 所以我们需要修改代码:

//修改公共配置文件  bbs/config/config_global.php
$_config['memory']['memcache']['server'] = 'true';
$_config['memory']['memcache']['host'][]='192.168.1.1';
$_config['memory']['memcache']['host'][]='192.168.1.2';
//$_config['memory']['memcache']['server'] = 'localhost';
//$_config['memory']['memcache']['port'] = 11211;
$_config['memory']['memcache']['pconnect'] = 1;
$_config['memory']['memcache']['timeout'] = 1;


//修改 discuz memcache class类  bbs/source/class/class_memcache.php 
 function init($config) {
                if (! empty ( $config ['server'] )) {
                        $this->obj = new Memcache ();
                        if ($config ['pconnect']) {
                                $i = 1;
                                foreach ( $config ['host'] as $one_host ) {
                                        if ($i == 1) {
                                                $connect = @$this->obj->pconnect ( $one_host, 11211 );
                                        } else {
                                                $connect = @$this->obj->addServer ( $one_host, 11211 );
                                        }
                                        $i ++;
                                }
                                // $connect = @$this->obj->pconnect($config['server'], $config['port']);
//因为使用长连接 短连接就不改了
                        } else {
                                $connect = @$this->obj->connect ( $config ['server'], $config ['port'] );
                        }
                        $this->enable = $connect ? true : false;
                }
        }

discuz memcache 使用

require_once libfile('class/memcache');
@include DISCUZ_ROOT.'./config/config_global.php';
//获取
$m = new discuz_memcache();
$m->init($_config['memory']['memcache']);
$mail="5991168@qc.com";
$userinfo=$m->get(md5($email));

//写入 
$md5_name=md5($email);
$m->set($md5_name,$userinfo,MEMCACHE_COMPRESSED,time()+43200);

discuz 存储session by memcache


//修改配置文件 php.ini
php_value[session.save_handler] = memcached
php_value[session.save_path] = 192.168.1.1:11211
