WP-CLI，它可以让我们在命令行工具里输入相应的命令，去控制 WordPress 的行为。比如去升级 WordPress，去安装个插件，多站点，去管理用户，评论，主题等等。这跟 Drupal 的 Drush 有点类似。在 WordPress 上面，我们就是去使用 WP-CLI 这个工具。

下面，我们还是在自己的 Linux 系统的服务器上，去安装一个 WP-CLI ，然后再用它使用命令去控制 WordPress，你也可以在本地电脑上去测试，需要使用类 Unix  的操作系统，比如 OS X, Linux, FreeBSD … 如果你使用是 Windows 操作系统，可以去安装一个 Linux 系统的虚拟机，或者，你也可以直接买一台服务器去测试一下。下面， 我会在ubuntu操作系统的服务器上测试这个 WP-CLI 工具。

 

需求

• Unix-like 环境（OS X， Linux，FreeBSD，Cygwin）
• PHP 5.3.2 或以上版本
• WordPress 3.5.2 或以上版本

 

安装

先使用 ssh 登录到服务器，然后进入到某个目录以后，使用 wget 或者 curl 命令去下载 wp-cli：

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

为下载的文件添加可执行权限：

sudo chmod +x wp-cli.phar

移动到bin目录：

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

查看版本信息：

$ wp --info

使用

输入 wp 命令，回车以后，你会看到所有可以执行的命令，或者查看 wp-cli 官方提供的命令列表。下面我们可以试一下用 wp-cli 去升级 WordPress，先进入到你的 WordPress 网站的目录下面。然后输入：

wp core update

返回：

正在从http://cn.wordpress.org/wordpress-4.9.4-zh_CN.zip下载更新文件...
正在解压缩升级文件...

安装wordpress并配置数据库

cd /var/www/wordpress

下载wordpress：

sudo wp --allow-root  core download --version=4.9.4

配置MySQL数据库：

mysql -u root -p
Enter password:

创建一个新用户和一个数据库：

mysql> create database wordpress;
Query OK, 1 row affected (0.00 sec)
 
mysql> create user w_p@localhost identified by 'w_p@';
Query OK, 0 rows affected (0.00 sec)
 
mysql> grant all privileges on wordpress.* to w_p@localhost identified by 'w_p@';
Query OK, 0 rows affected (0.00 sec)
