从数据库添加一个wordpress的admin用户

主要是通过直接添加一个用户来实现。
有2个表：wp-users和wp-usermeta。

1、向wp_users表添加一个用户：Fill in the following fields.

• ID is any number you choose
• user_login is the username for accessing the WordPress Dashboard.
• user_pass is the password for the user. Make sure to select MD5 in the functions menu (这里的意思是，可以直接填写明文密码，选择左侧函数页选项里的MD5，就自动加密了)
• user_nicename is the nickname for the user
• user_email is the email address you want to associate with this user
• user_registered is the date and time for when this user is registered
• user_status should be set to 0
• display_name is the name that will be displayed for this user on your site

2、 向wp_usermeta表添加一个记录：

• user_id is the ID you entered in the previous step
• meta_key should be the phrase wp_capabilities
• meta_value should be a:1:{s:13:"administrator";s:1:"1";}
