咨询关于mysql_connect超时连接

lxp642 2014-12-19 10:34:22

烦请各位提供思路，分析可能存在的问题

连接代码,以下简化的生产代码
$start_time = date('Y-m-d H:i:s');
if(mysql_connect($config['dbhost'], $config['dbuser'], $config['dbpw'], TRUE)){
// something code
}else{
error_log('['. date('Y-m-d H:i:s') .'] 连接失败'.$this->error().' start='.$start_time.' host='.$config['dbhost'].' user='.$config['dbuser']."\n", 3, UC_ROOT.'logs/sqlerr_'.date('Y-m-d').'.log');
}
连接超时日志，有个规律是7秒这个值

以下为部分php.ini部分参数设置信息
php.ini
max_execution_time = 30
max_input_time = 60
default_socket_timeout = 60
mysql.connect_timeout => 60 => 60
default_socket_timeout => 60 => 60
