Question

我尝试在我的服务器上使用wp命令，但是每次运行时都会收到这些警告（wp实际上会有效，但它很有声音关于警告）：

运行命令时：

myuser@serverhtml$ wp

PHP Warning:  session_start(): open(/var/lib/php/session/sess_6r7oiur5t1lhsokahj590d1aa7, O_RDWR) failed: Permission denied (13) in /home/int/myuser/html/wp-content/plugins/wp-cassify/classes/wp_cassify_plugin.php on line 201

问题似乎与我的wp-cassify插件（https://github.com/CGCookie/wp-cassify）及其session_start功能的使用有关，但知识不足以知道从何处开始。

Answer 1

初始化插件时，Wordpress似乎已经启动了会话处理程序。因此，PHP会打印一个警告。

您可以修改插件以将/home/int/myuser/html/wp-content/plugins/wp-cassify/classes/wp_cassify_plugin.php调用包装在测试中，如建议的Loopo。它应该在第201行的permission denied文件中。

此修复程序应该消除所有其他错误。（我怀疑要引发session_start错误，因为文件被打开两次，因为{{1}}被调用了两次。）

Answer 2

您似乎没有对服务器上的/var/lib/php/session/sess_6r7oiur5t1lhsokahj590d1aa7文件的写入权限，您可以解决它。如果您可以访问服务器的系统文件，则可以使此文件可写，或者如果您无权访问此文件夹，则可以更改会话目录。在调用session_start（）之前调用session_save_path（）并为其指定服务器可写入的目录的名称。有关详细信息，您可以see here

Answer 3

您是否尝试卸载wp-cli并在新位置重新安装？每当我在共享主机上时，我首先运行wp命令时遇到问题。每次我都要写一个别名。但是，我最终重新安装到了一个bin目录，在那里我拥有不同的权限，而且工作得更好。

Answer 4

解决方案最终要添加：

ini_set('session.save_path',realpath(dirname($_SERVER['DOCUMENT_ROOT']) . '/../session'));

在wp-config.php内。
