要安装WP-CLI，请确保您拥有具有SSH访问权限的托管帐户。大多数共享主机提供商都不允许您访问SSH。如果您喜欢启动自己的服务器，则DigitalOcean，Linode和AWS等提供商非常适合此目的。

Other requirements are basic:

如何安装WP-CLI (How to Install WP-CLI)

第1步 (Step 1)

First connect to your server’s command line through SSH. You can install the latest version of WP-CLI using the cURL or wget command. The WP-CLI installation file is available as a phar file and the latest version can be found at:

首先通过SSH连接到服务器的命令行。您可以使用cURL或wget命令安装最新版本的WP-CLI。 WP-CLI安装文件以phar文件形式提供，最新版本可在以下位置找到：

https://raw.github.com/wp-cli/builds/gh-pages/phar/wp-cli.phar

Using the cURL command, type:

使用cURL命令，键入：

curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar

https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar

This will download and extract the WP-CLI files to your root user directory.

这将下载WP-CLI文件并将其解压缩到您的根用户目录。

第2步 (Step 2)

Next, we will set the permissions to make it executable. Enter the following command:

接下来，我们将设置权限以使其可执行。输入以下命令：

chmod +x wp-cli.phar

第三步 (Step 3)

Optionally, we can move wp-cli.phar to a folder and rename it to wp. This will help us use the WP-CLI commands by just typing ‘wp’ at the start of the commands.

(可选)我们可以将wp-cli.phar移至文件夹并将其重命名为wp。通过在命令开头键入“ wp”，这将有助于我们使用WP-CLI命令。

sudo mv wp-cli.phar /usr/local/bin/wp

That’s it! Now we can jump in to use many of the WP-CLI commands.

而已！现在我们可以跳入使用许多WP-CLI命令。

使用WP-CLI安装WordPress (Installing WordPress with WP-CLI)

If you haven’t installed WordPress by using any other method on your server, then you can easily do so using WP-CLI command wp core install. Along with that command we need to pass parameters such as URL, Title, Admin Username, Password and Admin Email.

如果您尚未在服务器上使用任何其他方法来安装WordPress，则可以使用WP-CLI命令wp core install轻松地进行wp core install 。与该命令一起，我们需要传递诸如URL，标题，管理员用户名，密码和管理员电子邮件之类的参数。

wp core install --url="your_domain"  --title="Blog Title" --admin_user="admin username" --admin_password="enter_your_password" --admin_email="enter_your_email"

使用WP-CLI安装主题 (Installing Themes with WP-CLI)

Importing and installing themes is much quicker through WP-CLI than going into WordPress admin, searching and then activating it.

通过WP-CLI导入和安装主题比进入WordPress管理，搜索然后激活它要快得多。

It connects your server directly to the WordPress theme repository and imports the theme in a matter of a few seconds. For example, to install a theme like TwentyTen, we will use the following command:

它将您的服务器直接连接到WordPress主题存储库，并在几秒钟内导入主题。例如，要安装类似TwentyTen的主题，我们将使用以下命令：

wp theme install twentyten

Similarly, to install P2 theme, our command will become:

同样，要安装P2主题，我们的命令将变为：

wp theme install p2

To activate the themes on your WordPress website, you will need to use the following command:

要在WordPress网站上激活主题，您将需要使用以下命令：

wp theme activate p2

使用WP-CLI安装插件 (Installing Plugins with WP-CLI)

Just like the themes, plugins can also be installed right from the official repository. Installation is seamless and takes almost no time.

就像主题一样，插件也可以直接从官方存储库安装。安装是无缝的，几乎不需要时间。

For example: wp plugin install woocommerce

例如： wp plugin install woocommerce

The above command will install the WooCommerce plugin on your website. To activate it, we will use the command:

上面的命令将在您的网站上安装WooCommerce插件。要激活它，我们将使用以下命令：

wp plugin activate woocommerce

Similarly, to deactivate any plugin, the command becomes:

同样，要停用任何插件，命令将变为：

wp plugin deactivate woocommerce

使用WP-CLI更新WordPress核心，主题和插件 (Updating WordPress Core, Themes and Plugins with WP-CLI)

Repetitive and often time consuming task of updating the WordPress core, themes and plugins can be easily carried out through the command line.

更新WordPress核心，主题和插件的重复性任务通常很耗时，可以通过命令行轻松完成。

To update the WordPress core to the latest stable release of WordPress, the command is:

要将WordPress核心更新为WordPress的最新稳定版本，命令为：

wp core update

If you want to update to a specific version, for example you have WordPress 3.7 and want to move to WordPress 4.0 instead of WordPress 4.3, use the command:

如果要更新到特定版本，例如，您拥有WordPress 3.7，并且想要迁移到WordPress 4.0而不是WordPress 4.3，请使用以下命令：

wp core update --version=4.0

Or, if for any reason you want to revert back your WordPress site to the previous version, the command is:

或者，如果出于任何原因您想将WordPress网站恢复为以前的版本，则命令为：

wp core update --version=3.9 --force

To update plugins, you can either define one plugin to update or better still, update all the plugins in one go.

要更新插件，您可以定义一个要更新的插件，或者更好的方法是一次性更新所有插件。

wp plugin update woocommerce
wp plugin update --all

A similar method applies to the themes. You can update WordPress themes through WP-CLI with following command

类似的方法适用于主题。您可以使用以下命令通过WP-CLI更新WordPress主题

wp theme update twentyten
wp theme update --all
