php网站搭建的数据库如何转移

把A中的q1倒出来 mysqldump -uadmin1 -padmin111 Q1 Q1.sql

然后再B中新建Q2，create database Q2

应用Q2 use Q2

导入Q1 source Q1.sql

赋予用户 grant all privileges on Q2.* to 'admin2'@localhost identified by 'admin2222'

这样就可以了！

Q1: php实现redis数据库指定库号迁移的方法

这篇文章主要介绍了php实现redis数据库指定库号迁移的方法,涉及对于redis数据库的操作技巧,非常具有实用价值,需要的朋友可以参考下

本文实例讲述了php实现redis数据库指定库号迁移的方法,分享给大家供大家参考。具体如下：

redis普通的数据库迁移,只能整个redis

save,或者利用主从,当然也可以安装一个redis-dump,不过比较麻烦,这里提供一种php的脚本,实现指定库号的迁移,其实也就是遍历根据存储类型,读出来,插入新库,效果是这样:

代码如下:

[root@localhost

~]#

php

1.php

1/407

101/407

201/407

301/407

401/407

PHP实例代码如下:

代码如下:

?php

$from

'10.0.2.52:6379/7';

$to

'127.0.0.1:6379/7';

$from_redis

redis_init($from);

$to_redis

redis_init($to);

$keys

$from_redis-keys('*');

$count

$total

count($keys);

foreach($keys

$key){

if(++$count

100

1){

echo

"$count/$totaln";

}

$type

$from_redis-type($key);

switch($type){

case

Redis::REDIS_STRING:

$val

$from_redis-get($key);

$to_redis-set($key,

$val);

break;

case

Redis::REDIS_LIST:

$list

$from_redis-lRange($key,

-1);

foreach($list

$val){

$to_redis-rPush($key,

$val);

}

break;

case

Redis::REDIS_HASH:

$hash

$from_redis-hGetAll($key);

$to_redis-hMSet($key,

$hash);

break;

case

Redis::REDIS_ZSET:

$zset

$from_redis-zRange($key,

-1,

true);

foreach($zset

$val=$score){

$to_redis-zAdd($key,

$score,

$val);

}

break;

}

function

redis_init($conf){

$redis

new

Redis();

preg_match('/^([^:]+)(:[0-9]+)?/(.+)?/',

$conf,

$ms);

$host

$ms[1];

$port

trim($ms[2],

':');

$db

$ms[3];

$redis-connect($host,

$port);

$redis-select($db);

return

$redis;

}

希望本文所述对大家的php程序设计有所帮助。

Q2: 如何在PHP项目中使用phinx进行数据迁移和建表

建表

phinx\bin\phinx.bat migrate -e production

建设 phinx.yml文件

paths:

migrations: %%PHINX_CONFIG_DIR%%\database\migrations

seeds: %%PHINX_CONFIG_DIR%%\database\seeds

environments:

default_migration_table: phinxlog

default_database: development

production:

adapter: mysql

host: localhost

user: root

pass: ‘‘

port: 3306

charset: utf8

development:

adapter: mysql

host: localhost

user: root

pass: ‘‘

port: 3306

charset: utf8

testing:

adapter: mysql

host: localhost

user: root

pass: ‘‘

port: 3306

charset: utf8

数据迁移命令如下：

phinx\bin\phinx.bat seed:run -e production

%%PHINX_CONFIG_DIR%%\database\seeds下面的文件示例CreateGroupsTable.php如下：

Q3: PHP如何使用表单将这个数据库数据转移到另一个数据去

在下写的转用户的程序,发出来给你参考下吧! 悬赏才5分,真吝啬!

$next = intval($_GET['start']);

if ($next == NULL)

{

$next = 0;

}

$x = new Mysql($conf['xoops']);

$u = new Mysql($conf['ucenter']);

$start = $num*$next;

$m = $num*($next+1);

echo 'p/pfont color="red"开始转换：第bfont color="blue"'.($start+1).'/font/b到bfont color="blue"'.$m.'/font/bbr/fonthr style="width:20%;" align="left" /';

//从xoops中提取数据

$sql = "SELECT `uid`,`uname`,`email`,`pass`,`user_regdate` FROM `{$xoops['prefix']}users` ORDER BY `uid` ASC LIMIT {$start},{$num}";

$rs = $x-oneRow($sql);

if(empty($rs)){

echo 'p/pfont color="blue"全部转换完毕/font';

die();

}

$result = $x-query($sql);

while ($x_data = mysql_fetch_array($result,MYSQL_ASSOC)){

$user = $x_data;

//从ucenter中读取数据

$sql = "SELECT `uid` FROM `".$ucenter['prefix']."members` WHERE `uid` = '".$user['uid']."' LIMIT 1";

$u_data = $u-oneRow($sql);

if(!empty($u_data)){

@$time_log = file_get_contents('uid_err_log.txt');
