Discuz!X3.4本地附件全部修改为远程附件的方法

进行操作前，请备份数据库。

一、转到

1、论坛后台–全局–上传设置–启用。

2、将目录data/attachment里面的文件夹移动到服务器上。

3、数据库执行sql语句。

论坛：

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;

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：

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;

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：
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;

1	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。

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;
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;
