这是我刚刚更新Drupal 7网站的方式Drush ，请注意，下面一些命令的输出是Drupal8的早期版本，但是这些命令也可以与Drupal7一起使用。

首先，执行以下操作：

• 备份Drupal 7数据库和文件
• 备份站点特定文件
  • .htaccess
  • robots.txt
  • sites/default/settings.php

然后运行以下命令：

drush sset system.maintenance_mode 1
drush cr
drush up drupal
drush updb
drush entup
drush sset system.maintenance_mode 0
drush cr

如果没有数据库或实体更新，则不需要中间的那两个命令，因此你可能只需要运行以下drush命令：

drush sset system.maintenance_mode 1
drush cr
drush up drupal
drush sset system.maintenance_mode 0
drush cr

也就是说，如果不确定的话，运行这些命令没有害处。

作为一个重要提示，我使用Drush 8运行这些命令。看起来命令与Drush 9.不同

注意：我创建了一个名为drush8的别名来运行这些命令，因为它们与Drush 8一起运行，（使用Drush 8更新Drupal 7网站有点令人困惑，），

这是如何使用Drush更新Drupal7网站的简短答案，如果你对更多信息感兴趣，请参阅下面的，(注释是晦涩的，但希望有用。)

从drush update drupal命令输出

以下是运行drush up drupal命令的输出：

$ drush up drupal

Update information last refreshed: July 22, 2017 - 12:00pm
 Name Installed Version Proposed version Message 
 Drupal 8.3.4 8.3.5 Update available

Code updates will be made to drupal core.
WARNING: Updating core will discard any modifications made to Drupal core files,
most noteworthy among these are .htaccess and robots.txt. If you have made any
modifications to these files, please back them up before updating so that you can
re-create your modifications in the updated version of the file.

Note: Updating core can potentially break your site. It is NOT recommended to update
production sites without prior testing.

关于Drupal 7Drush过程和命令的注释

有一个官方Drupal 7更新文档链接 。

整个过程相关的注释：

• 要确定哪些软件包可以更新(不改变东西)，请执行以下操作：
  • drush ups (aka，drush pm-updatestatus )，
• 在运行数据库备份之前清除缓存
  • drush cr (或drush cc all，如果你愿意)，
• 将Drupal 7站点置于维护模式
  • drush sset system.maintenance_mode 1
  • Drupal 7命令：
    • drush vset --exact maintenance_mode 1
    • drush cache-clear all
• 更新drupal核心
  • drush up drupal (与：drush pm-update drupal相同)
  • 注意：drush pm-update与运行drush pm-updatecode和drush updatedb相同
• 若要更新单个模块，如视图模块，请执行下列操作：
  • drush up views
• 仅应用安全更新：
  • drush up --security-only
• 应用必需的数据库和实体更新(理论上这不是必需的，因为drush up应该这样做)，
  • drush updb #数据库更新
  • drush entup #实体更新
• 如果一切正常，请将你的站点重新联机：
  • drush sset system.maintenance_mode 0
  • drush cr
  • Drupal 7命令
    • drush vset --exact maintenance_mode 0
    • drush cache-clear all

除了更新Drupal内核，我还运行了这些命令来更新显示的Drupal模块：

drush sset system.maintenance_mode 1
drush cr
drush up login_security
drush up metatag
drush up mollom
drush up similarterms
drush up token
drush updb
drush sset system.maintenance_mode 0
drush cr

其他drush命令

要获得你的Drupal网站的概述，请使用drush status ：

$ drush status

要确定可以更新哪些软件包/模块，而不进行更改(仅查询)，请使用drush pm-updatestatus，或它别名drush ups ：

drush cr
drush cc all
