在 Linux 服务器上轻松安装 WP-CLI

WP-CLI是2011年诞生和开发的一个功能。使用WP-CLI，您只需通过命令行界面即可轻松管理您的WordPress网站。通常，当您需要安装插件、主题或进行与 WordPress 相关的编辑时，您需要访问 WordPress 管理后台并通过单击鼠标进行操作，这有时会有点麻烦和耗时，对吗？

这就是为什么 WP-CLI 被开发来帮助您处理上述问题，我们不需要单独访问 WordPress 管理后台，仍然能够更快地管理我们的网站并节省大量时间。

WP-CLI 安装条件

您需要拥有服务器的 root 访问权限

安装说明

第 1 步：安装 WP-CLI

要安装WP-CLI，您需要通过 SSH 连接到您的 VPS/服务器并运行以下安装命令：

curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
php wp-cli.phar --info
chmod +x wp-cli.phar
sudo mv wp-cli.phar /usr/local/bin/wp

上述命令的解释：

命令1：从Github主页下载WP-CLI工具。
命令2：查看下载的WP-CLI信息
命令 3：委派执行下载的文件的权限
命令 4：将wp-cli.phar重命名为wp并将文件移动到/usr/local/bin（您可以在 VPS/服务器上的任何位置使用 wp 命令）

如果您想更快地安装，只需复制下面的命令并将其粘贴到您的服务器中即可完成。

wget https://tool.damtrungkien.info/cli/cli.sh && chmod +x cli.sh && bash cli.sh

第 2 步：如何使用 WP-CLI

注意：当您在服务器/VPS 服务器上安装 WP-CLI 并以 root 身份使用时，使用 WP-CLI 命令时，您需要在 CLI 命令行后添加 –allow-root选项。此外，要使用WP-CLI，您需要移动到您需要操作的WordPress网站的正确文档根文件夹。

下面是一些基本的 WP-CLI 命令，您可以看一下
