WP-CLI 是否与在 AWS Lightsail 上安装的 Bitnami 的 Wordpress 不兼容？

Question

在 Ubuntu 上使用新的 Wordpress 实例，我通过 these instructions 安装了 wp-cli。我试过downloading the .phar package, chmodding it, etc。我也试过installing a .deb package。在这两种情况下，我在运行 wp plugin update --all --debug 时都会遇到相同的错误：

我已经使用了list of support options，但仍然无法让 wp-cli 在 AWS Lightsail（又名 Bitnami）上正常工作。查看github 和wordpress.org forums，我发现很多用户都遇到了上述部分或全部错误。我尝试了所有建议的解决方法：

• wp-config.php：将 ABSPATH 行换成一个条件。
• wp-config.php：将 add_filter() 调用移动到 MU 插件中。
• 几个chmod 和chown 更改。

其中一些确实使它们各自的错误消失了，但wp 仍然无法更新插件等。

我是否需要创建在 PHP 调试输出中标识的缺失文件？

我是否应该不使用 AWS Lightsail/Bitnami？我真的需要wp-cli，所以我愿意转至 ec2 或其他任何地方。

Answer 1

我在那里看到两个不同的问题。

1. 您在wp-config.php 文件中使用了$_SERVER['HTTP_HOST']， 在运行 WP-CLI 时未设置。由于 WP-CLI 作为 命令行工具，一些仅限 Web 的 PHP 常量/变量是 没有设置。您需要手动设置这些或提供 条件覆盖。

2. WordPress 本身无法创建一个目录来解压 下载的插件存档文件。这可能是由于 1. 以上（如 WordPress 可能正在寻找错误的位置），或者它可能是 不相关的问题，例如使用不同的用户运行 WP-CLI 没有所需的权限。

这两个问题都不是由 WP-CLI 直接引起的，而是您的 WordPress 安装的特定设置的结果。

Answer 2

Bitnami 开发者在这里。

您可以尝试以daemon 用户身份运行命令吗？

 sudo su -s /bin/bash daemon

这是对服务器有写入权限的用户

Answer 3

谢谢哈维尔·萨梅隆！这正是我必须做的，按顺序：

sudo su -s /bin/bash daemon

export PATH=/opt/bitnami/varnish/bin:/opt/bitnami/sqlite/bin:/opt/bitnami/php/bin:/opt/bitnami/mysql/bin:/opt/bitnami/apache2/bin:/opt/bitnami/common/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

cd /home/bitnami/apps/wordpress/htdocs

现在它起作用了，因为以下是正确的：

1. 我是用户daemon。
2. 我的$PATH 能够找到/opt/bitnami/php/bin/php。
3. 我在正确的目录中：/home/bitnami/apps/wordpress/htdocs

以下命令运行成功：wp plugin update --all --debug
