得到此错误消息：dbModel读取资源未实现Zend_Db_Adapter_Abstract

我把我的magento项目放在Linux服务器上。首先显示错误日志消息，但是缺少文件夹var。然后，我创建了var文件夹，并赋予它777权限，并与缓存，报告，会话相同。在报告文件夹的错误文件中，我收到以下消息：

那么什么会引起这个问题呢？为什么呢？而我解决了吗？

在建立正确的数据库连接后，我还更改了这一行：

<disable_local_modules>false</disable_local_modules>

进入这个

<disable_local_modules>true</disable_local_modules>

我使用以下命令将777权限递归授予var文件夹：

chmod -R 777 var

就我而言

rm -rf var/cache/*

解决了问题- 虽然我将local.xml更改为符号链接

就我而言，我只需要更改var文件夹的权限

chmod -R 777 var

看起来这是缓存问题，您需要删除缓存，使用magerun刷新它或删除缓存文件夹rm -rf var / cache。

false这行只是禁用了app / code / local /文件夹下的所有模块。

运行以下命令，尽情享受吧！

chown -R username:group var/
chmod -R 777 var/
rm -rf /var/cache/
