今天微博上有朋友问到我Mybb如何配置主从其实我对mybb不是很熟悉,就大致看了一下DB发现是可以配置主从的在inc/config.php中配置如下$con fig['database']['read']['hostname'] = 'localhost';$config['database']['read']['username'] = 'root';$config['database']['read']['password'] = '';$config['database']['write']['hostname'] = 'localhost';$config['database']['write']['username'] = 'root';$config['database']['write']['password'] = '';//read为从 write为主 多个的时候['r ead'][0]['hostname']这样以数据配置即可但是在db_mysql.php中我却发现在处理主从的时候。有一个不和谐的代码。目前我也没有想明白目 的175行if(array_key_exists('hostname', $connections[$type])) { $details = $connections[$type]; unset($connections);//这里unset了 就肯定只能够连接到read的第一个数据库上 $connections[$type][] = $details;}我没有搞明白目的所以没有进行修改。如果要实现要实现只需要重新处理一下$connections数组就可以解决我这里就不累述。
处理主从的代码
foreach(array('read', 'write') as $type) { print_r($connections);if(!is_array($connections[$type])) { break; } if(array_key_exists('hostname', $connections[$type])) { $details = $connections[$type]; unset($connections); $connections[$type][] = $details; } // Shuffle the connections shuffle($connections[$type]); // Loop-de-loop foreach($connections[$type] as $single_connection) { $connect_function = "mysql_connect"; if($single_connection['pconnect']) { $connect_function = "mysql_pconnect"; } $link = $type."_link"; $this->get_execution_time(); $this->$link = @$connect_function($single_connection['hostname'], $single_connection['username'], $single_connection['password'], 1); $time_spent = $this->get_execution_time(); $this->query_time += $time_spent; // Successful connection? break down brother! if($this->$link) { $this->connections[] = "[".strtoupper($type)."] {$single_connection['username']}@{$single_connection['hostname']} (Connected in ".number_format($time_spent, 0)."s)"; break; } else { $this->connections[] = "<span style="color: red">[FAILED] [".strtoupper($type)."] {$single_connection['username']}@{$single_connection['hostname']}</span>"; } } }
