discuzx版本地附件与远程附件如何转换

进行操作前，请备份数据库

一、本地转到远程

1、论坛后台–全局–上传设置–启用远程附件

2、将本地附件目录data/attachment里面的文件夹移动到远程服务器上

3、数据库执行sql语句
论坛的（0表示本地，1表示远程，）

 update pre_forum_attachment_0 set remote=1 where remote=0;
 update pre_forum_attachment_1 set remote=1 where remote=0;
 update pre_forum_attachment_2 set remote=1 where remote=0;
 update pre_forum_attachment_3 set remote=1 where remote=0;
 update pre_forum_attachment_4 set remote=1 where remote=0;
 update pre_forum_attachment_5 set remote=1 where remote=0;
 update pre_forum_attachment_6 set remote=1 where remote=0;
 update pre_forum_attachment_7 set remote=1 where remote=0;
 update pre_forum_attachment_8 set remote=1 where remote=0;
 update pre_forum_attachment_9 set remote=1 where remote=0;

门户的：

 update pre_portal_article_title set remote=1 where remote=0;
 update pre_portal_attachment set remote=1 where remote=0;
 update pre_portal_topic_pic set remote=1 where remote=0;

相册的{相册表中的remote取值还有一种情况为remote=2(论坛附件图片保存到相册)}

 update pre_home_pic set remote=remote+1;

二、远程转到本地

后台关闭远程附件设置，将附件移动到本地服务器的 data/attachment目录后执行sql即可
0表示本地，1表示远程

 update pre_forum_attachment_0 set remote=0 where remote=1;
 update pre_forum_attachment_1 set remote=0 where remote=1;
 update pre_forum_attachment_2 set remote=0 where remote=1;
 update pre_forum_attachment_3 set remote=0 where remote=1;
 update pre_forum_attachment_4 set remote=0 where remote=1;
 update pre_forum_attachment_5 set remote=0 where remote=1;
 update pre_forum_attachment_6 set remote=0 where remote=1;
 update pre_forum_attachment_7 set remote=0 where remote=1;
 update pre_forum_attachment_8 set remote=0 where remote=1;
 update pre_forum_attachment_9 set remote=0 where remote=1;

门户+相册

 update pre_portal_article_title set remote=0 where remote=1;
 update pre_portal_attachment set remote=0 where remote=1;
 update pre_portal_topic_pic set remote=0 where remote=1;
 update pre_home_pic set remote=remote-1;
