版本忘记了。。
是gbk版本。
老论坛。在我17岁那年玩的
由于当时未满18.。随便上网 搜了个身份正。。拿去 beian了。
后来beian重申。。
哪能记得当时用的谁的。。。
就这样。。 beian被取消了。。
无奈啊。

现在放国外服务器上 挂着吧。

分成一个索引表
cdb_forum_attachment
还有0-9的附件详情表
cdb_forum_attachment_$1

根据 tid决定的最后一位决定存放的表

用php处理下把

<?php
	header("Content-Type:text/html;charset=UTF-8");
require_once './include/common.inc.php';
$query=$db->query("select a.*,f.description from `cdb_attachments` as a left join `cdb_attachmentfields` as f on a.aid=f.aid  limit 9999999");
$a=0;
while($r=$db->fetch_array($query)){
	$tableid=substr($r['tid'],-1);
	$at[]=array('aid'=>$r['aid'],	'tid'=>$r['tid'],'pid'=>$r['pid'],'uid'=>$r['uid'],'tableid'=>$tableid,'downloads'=>$r['downloads']);
	$atb[$tableid][]=array(

$db->query("TRUNCATE TABLE `cdb_forum_attachment`");
	$sql="INSERT INTO `cdb_forum_attachment` (`aid`, `tid`, `pid`, `uid`, `tableid`, `downloads`) VALUES";
	foreach($at as $a){

		}
	$sql=substr($sql,0,-1);	
	$db->query($sql);
	for($i=0;$i<10;$i++){
			$db->query("TRUNCATE TABLE `cdb_forum_attachment_$i`");
$sql="INSERT INTO `discuz_new`.`cdb_forum_attachment_$i` (`aid`, `tid`, `pid`, `uid`, `dateline`, `filename`, `filesize`, `attachment`, `remote`, `description`, `readperm`, `price`, `isimage`, `width`, `thumb`, `picid`) VALUES ";
	foreach($atb[$i] as $a){

	//echo $sql;		
	$db->query($sql);
		echo "已完成 表 $i 共有  {$atcount[$i]} 条记录 \r\n";

?>

只要熟悉 表结构。这些挺容易操作的
用这样的方法 可以把任意一个论坛系统自由的转来转去。

用户积分增加

列入 用户访问空间时增加1分

用户首次登陆增加10分

那么每次操作都要insert一次

这显然很浪费

如果可以缓存一次性写入那么就可以降低MYSQL的压力了

像上面的情况我只要一次性增加11分即可

在THINKPHP中找到了方法

下面代码转载自THINKPHP(advmodel.class.php)

setLazyInc($field,$condition='',$step=1,$lazyTime=0) { //缓存累加
        if(empty($condition) && isset($this->options['where']))
            $condition   =  $this->options['where'];
        if(empty($condition)) { // 没有条件不做任何更新
            return false;
        }
        if($lazyTime>0) {// 延迟写入
            $guid =  md5($this->name.'_'.$field.'_'.serialize($condition));
            $step = $this->lazyWrite($guid,$step,$lazyTime);
            if(false === $step ) return true; // 等待下次写入
        }
        return $this->setField($field,array('exp',$field.'+'.$step),$condition);
    }
 
function lazyWrite($guid,$step,$lazyTime) {   
        if(false !== ($value = F($guid))) { // 存在缓存写入数据
            if(time()>F($guid.'_time')+$lazyTime) {
                // 延时更新时间到了，删除缓存数据 并实际写入数据库
                F($guid,NULL);
                F($guid.'_time',NULL);
                return $value+$step;
            }else{
                // 追加数据到缓存
                F($guid,$value+$step);
                return false;
            }
        }else{ // 没有缓存数据
            F($guid,$step);
            // 计时开始
            F($guid.'_time',time());
            return false;
        }
    }

上面有个 FUNCTION F 在FACTIONS.PHP

// 快速文件数据读取和保存 针对简单类型数据 字符串、数组
function F($name,$value='',$path=DATA_PATH) { //修改$path为自己的缓存路径
    static $_cache = array();
    $filename   =   $path.$name.'.php';
    if('' !== $value) {
        if(is_null($value)) {
            // 删除缓存
            return unlink($filename);
        }else{
            // 缓存数据
            $dir   =  dirname($filename);
            // 目录不存在则创建
            if(!is_dir($dir))  mkdir($dir);
            return file_put_contents($filename,"<?php\nreturn ".var_export($value,true).";\n?>");
        }
    }

调用方法

setLazyDec($field,$condition='',$step=1,$lazyTime=0) 
//根据需要 自己修改吧我加入了table 等多个
function lazyaddint($table,$field,$condition='',$num=1,$ltime=0)
//调用方法 更具实际需要修改吧
lazyaddint('表明','字段名',"WHERE条件",增加数量,缓存时间);

此方法 会在缓存目录中创建2个临时文件

//07e8c1b06dbdc4f282bf7bf9311a1fce_time.php
<?php
return 1299602761;
?>
 
//07e8c1b06dbdc4f282bf7bf9311a1fce.php
<?php
return 21;
?>

根据时间超过 设定的时间就写入数据库
此方法已经适用无问题
感觉方法不太好.. 期待MEMCACHED的方式

所以直接使用MYSQL命令直接导入

费解
上网查阅后有说使用-FORCE 强制导入

mysql uynetwork <a.sql -force -u root -p

传言 源里面已经加入了NGINX

通过APT-GET安装 NGINX

sudo apt-get install nginx

装好后 可以直接用WEB访问了

然后安装MYSQL-SERVER MYSQL-CLIENT

因为在光盘中带了这个包

免去了下载的过程

填加到源里面

apt-cdrom add

安装 sudo apt-get install mysql-server mysql-client

安装PHP

sudo apt-get install php5-cli php5-cgi  php5-mysql

另外还需要安装 LIGHTTPD

apt-get install lighttpd

这个时候 NGINX 已经启动了所以这个起不来 80端口冲突

然后关掉这个服务的自动启动

REDHAT  CENTOS中都有个 NTSYSV 还有 CHKCONFIG

在UBUNTU 中没的

今天装了个sysv-rc-conf

同样是通过APT-GET安装的(这个东西比YUM 还好用)

然后把 LIGHTTPD 关了

修改nginx的配置文件：/etc/nginx/sites-available/default
修改 server_name 192.168.1.88;(我ETH0 的IP 是这个)
修改index的一行修改为：
index index.php index.html index.htm;

经常需要翻翻的

只是图一个方便


导出要用到MySQL的mysqldump工具，基本用法是：

shell> mysqldump [OPTIONS] database [tables]

如果你不给定任何表，整个数据库将被导出。

通过执行mysqldump –help，你能得到你mysqldump的版本支持的选项表。

注意，如果你运行mysqldump没有–quick或–opt选项，mysqldump将在导出结果前装载整个结果集到内存中，如果你正在导出一个大的数据库，这将可能是一个问题。

mysqldump支持下列选项：

–add-locks
在每个表导出之前增加LOCK TABLES并且之后UNLOCK TABLE。(为了使得更快地插入到MySQL)。
–add-drop-table
在每个create语句之前增加一个drop table。
–allow-keywords
允许创建是关键词的列名字。这由表名前缀于每个列名做到。
-c, –complete-insert
使用完整的insert语句(用列名字)。
-C, –compress
如果客户和服务器均支持压缩，压缩两者间所有的信息。
–delayed
用INSERT DELAYED命令插入行。
-e, –extended-insert
使用全新多行INSERT语法。（给出更紧缩并且更快的插入语句）
-#, –debug[=option_string]
跟踪程序的使用(为了调试)。
–help
显示一条帮助消息并且退出。
–fields-terminated-by=…
　
–fields-enclosed-by=…
　
–fields-optionally-enclosed-by=…
　
–fields-escaped-by=…
　
–fields-terminated-by=…
这些选择与-T选择一起使用，并且有相应的LOAD DATA INFILE子句相同的含义。
LOAD DATA INFILE语法。
-F, –flush-logs
在开始导出前，洗掉在MySQL服务器中的日志文件。
-f, –force,
即使我们在一个表导出期间得到一个SQL错误，继续。
-h, –host=..
从命名的主机上的MySQL服务器导出数据。缺省主机是localhost。
-l, –lock-tables.
为开始导出锁定所有表。
-t, –no-create-info
不写入表创建信息(CREATE TABLE语句）
-d, –no-data
不写入表的任何行信息。如果你只想得到一个表的结构的导出，这是很有用的！
–opt
同–quick –add-drop-table –add-locks –extended-insert –lock-tables。
应该给你为读入一个MySQL服务器的尽可能最快的导出。
-pyour_pass, –password[=your_pass]
与服务器连接时使用的口令。如果你不指定“=your_pass”部分，mysqldump需要来自终端的口令。
-P port_num, –port=port_num
与一台主机连接时使用的TCP/IP端口号。（这用于连接到localhost以外的主机，因为它使用 Unix套接字。）
-q, –quick
不缓冲查询，直接导出至stdout；使用mysql_use_result()做它。
-S /path/to/socket, –socket=/path/to/socket
与localhost连接时（它是缺省主机)使用的套接字文件。
-T, –tab=path-to-some-directory
对于每个给定的表，创建一个table_name.sql文件，它包含SQL CREATE 命令，和一个table_name.txt文件，它包含数据。 注意：这只有在mysqldump运行在mysqld守护进程运行的同一台机器上的时候才工作。.txt文件的格式根据–fields-xxx和–lines–xxx选项来定。
-u user_name, –user=user_name
与服务器连接时，MySQL使用的用户名。缺省值是你的Unix登录名。
-O var=option, –set-variable var=option设置一个变量的值。可能的变量被列在下面。
-v, –verbose
冗长模式。打印出程序所做的更多的信息。
-V, –version
打印版本信息并且退出。
-w, –where=’where-condition’
只导出被选择了的记录；注意引号是强制的！
“–where=user=’jimf’” “-wuserid>1″ “-wuserid<1″ 最常见的mysqldump使用可能制作整个数据库的一个备份： mysqldump –opt database > backup-file.sql

但是它对用来自于一个数据库的信息充实另外一个MySQL数据库也是有用的：

mysqldump –opt database | mysql –host=remote-host -C database

由于mysqldump导出的是完整的SQL语句，所以用mysql客户程序很容易就能把数据导入了：

shell> mysqladmin create target_db_name
shell> mysql target_db_name < backup-file.sql 就是 shell> mysql 库名 < 文件名

mysqldump -u 用户名 -p 数据库名 > 导出的文件名

mysqldump -u wcnc -p smgp_apps_wcnc > wcnc.sql

2.导出一个表

mysqldump -u 用户名 -p 数据库名 表名> 导出的文件名

mysqldump -u wcnc -p smgp_apps_wcnc users> wcnc_users.sql

3.导出一个数据库结构

mysqldump -u wcnc -p -d –add-drop-table smgp_apps_wcnc >d:wcnc_db.sql

-d 没有数据 –add-drop-table 在每个create语句之前增加一个drop table

4.导入数据库

常用source 命令

进入mysql数据库控制台，

如mysql -u root -p

mysql>use 数据库

然后使用source命令，后面参数为脚本文件(如这里用到的.sql)

mysql>source d:wcnc_db.sql
