PHP在线安装MySQL数据库实例教程

首先我们看下数据库安装表材料sucainiu.sql和sucainiu_data.sql

创建表结构sucainiu.sql

CREATE TABLE IF NOT EXISTS `meal_accounts` ( 
  `id` int(5) NOT NULL AUTO_INCREMENT, 
  `name` varchar(20) NOT NULL, 
  `name2` varchar(30) NOT NULL, 
  `key` varchar(50) NOT NULL, 
  `secret` varchar(50) NOT NULL, 
  `code` varchar(30) NOT NULL, 
  `ord` int(6) NOT NULL, 
  `is_check` tinyint(1) NOT NULL, 
  `logo` varchar(100) DEFAULT NULL, 
  `cla` varchar(20) DEFAULT NULL, 
  PRIMARY KEY (`id`) 
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=4 ;

插入数据表sucainiu_data.sql

INSERT INTO `meal_accounts` (`id`, `name`, `name2`, `key`, `secret`, `code`, `ord`, `is_check`, `logo`, `cla`) VALUES 
(1, 'qq', 'QQ登陆', '100433042', 'dd3134e26321bce95a446d659ef0020f', 'qq', 1, 0, 'Public/images/top_qq.png', 'login-type4'), 
(2, 'sina', '新浪微博登陆', '4264169412', '9ae7ccc2dc16a4942596ce95bfa64e51', 'sina', 2, 0, 'Public/images/top_weibo.png', 'login-type2'), 
(3, 'renren', '人人网登陆', '0cb72f1d2d7942a1aad79c33cbce4e1a', '992b87a8217445a2b43c8f14cb65139d', 'renren', 3, 0, 'Public/images/top_renren.png', 'login-type3');

index.php步骤2：运行环境检测

$phpv = @phpversion(); 
$os = PHP_OS; 
$os = php_uname(); 
$tmp = function_exists('gd_info') ? gd_info() : array(); 
$server = $_SERVER["SERVER_SOFTWARE"]; 
$host = (empty($_SERVER["SERVER_ADDR"]) ? $_SERVER["SERVER_HOST"] : $_SERVER["SERVER_ADDR"]); 
$name = $_SERVER["SERVER_NAME"]; 
$max_execution_time = ini_get('max_execution_time'); 
$allow_reference = (ini_get('allow_call_time_pass_reference') ? '<font color=green>[√]On</font>': '<font color=red>[×]Off</font>'); 
$allow_url_fopen = (ini_get('allow_url_fopen') ? '<font color=green>[√]On</font>': '<font color=red>[×]Off</font>'); 
$safe_mode = (ini_get('safe_mode') ? '<font color=red>[×]On</font>': '<font color=green>[√]Off</font>'); 
 
$err = 0; 
if (empty($tmp['GD Version'])) { 
    $gd = '<font color=red>[×]Off</font>'; 
    $err++; 
} else { 
    $gd = '<font color=green>[√]On</font> '.$tmp['GD Version']; 
} 
if (function_exists('mysql_connect')) { 
    $mysql = '<font color=green>[√]On</font>'; 
} else { 
    $mysql = '<font color=red>[×]Off</font>'; 
    $err++; 
} 
if (ini_get('file_uploads')) { 
    $uploadSize = '<font color=green>[√]On</font> 文件限制:'.ini_get('upload_max_filesize'); 
} else { 
    $uploadSize = '禁止上传'; 
} 
if (function_exists('session_start')) { 
    $session = '<font color=green>[√]On</font>'; 
} else { 
    $session = '<font color=red>[×]Off</font>'; 
    $err++; 
} 
$folder = array('/', 'Uploads', 'Cache', 'Cache/Cache', 'Cache/Data', 'Cache/Temp', 'Cache/Logs'); 
include_once("./tmpl/step_2.html"); 
exit();

检查数据库配置

if ($_GET['testdbpwd']) { 
    $dbHost = $_POST['dbHost'].':'.$_POST['dbPort']; 
    $conn = @mysql_connect($dbHost, $_POST['dbUser'], $_POST['dbPwd']); 
    if ($conn) { 
        die("1"); 
    } else { 
        die(""); 
    } 
} 
$scriptName = !empty($_SERVER["REQUEST_URI"]) ? $scriptName = $_SERVER["REQUEST_URI"] : $scriptName = $_SERVER["PHP_SELF"]; 
$rootpath = @preg_replace("/\/(I|i)nstall\/index\.php(.*)$/", "", $scriptName); 
$domain = empty($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : $_SERVER['SERVER_NAME']; 
$domain = $domain.$rootpath; 
include_once("./tmpl/step_3.html"); 
exit();

创建表

//读取数据文件 
$sqldata = file_get_contents('./sucaihuo.sql'); 
$sqlFormat = sql_split($sqldata, $dbPrefix); 
 
/** 
              执行SQL语句 
             */ 
$counts = count($sqlFormat); 
 
if ($n < $counts) { 
    $sql = trim($sqlFormat[$n]); 
    $n++; 
 
    if (strstr($sql, 'CREATE TABLE')) { 
        preg_match('/CREATE TABLE IF NOT EXISTS `([^ ]*)`/', $sql, $matches); 
        mysql_query("DROP TABLE IF EXISTS `$matches[1]"); 
        $ret = mysql_query($sql); 
        //                    print_r($matches); 
        if ($ret) { 
            $message = '<font color="gree">成功创建数据表：'.$matches[1].'  </font><br />'; 
        } else { 
            $message = '<font  color="red">创建数据表失败：'.$matches[1].' </font><br />'; 
        } 
        $arr = array('n' = >$n, 'msg' = >$message); 
        echo json_encode($arr); 
        exit; 
    } 
}

读取配置文件，替换真实配置数据，并插入数据

//读取配置文件，并替换真实配置数据 
$strConfig = file_get_contents('./db.php'); 
$strConfig = str_replace('#DB_HOST#', $dbHost, $strConfig); 
$strConfig = str_replace('#DB_NAME#', $dbName, $strConfig); 
$strConfig = str_replace('#DB_USER#', $dbUser, $strConfig); 
$strConfig = str_replace('#DB_PWD#', $dbPwd, $strConfig); 
$strConfig = str_replace('#DB_PORT#', $dbPort, $strConfig); 
//            $strConfig = str_replace('#DB_PREFIX#', $dbPrefix, $strConfig); 
@file_put_contents('../Application/Common/Conf/config.php', $strConfig); 
 
//插入管理员 
$admin_pwd = md5($admin_pwd); 
$admin_last_time = $_SERVER['REQUEST_TIME']; 
$admin_last_ip = ip2long(get_client_ip()); 
$query = "INSERT INTO `{$dbPrefix}admin_user` (`name`,`pwd`,`truename`,`email`,`last_login`,`last_ip`) VALUES('$admin_name','$admin_pwd','超级管理员','$site_email','$admin_last_time','$admin_last_ip')"; 
mysql_query($query); 
$message = '成功添加管理员<br/>成功写入配置文件<br/>安装完成．'; 
$arr = array('n' = >999999, 'msg' = >$message); 
echo json_encode($arr);
