解決 drush PDOException: SQLSTATE[HY000] [2002]

今天在Mac OS中安裝Drush時遇到一個錯誤。

Drush command terminated abnormally due to an unrecoverable error. [error]
<h1>Additional uncaught exception thrown while handling exception.</h1>
<h2>Original</h2>
<p>PDOException: SQLSTATE[HY000] [2002] No such file or directory in drupal_is_denied() (line 1915 of /Applications/rubystack/apps/drupal/htdocs/includes/bootstrap.inc).</p>
<h2>Additional</h2>
<p>PDOException: SQLSTATE[HY000] [2002] No such file or directory in system_list() (line 165 of /Applications/rubystack/apps/drupal/htdocs/includes/module.inc).</p><hr />

Process finished with exit code 1 at 17:04:06.

這個問題錯誤主要時PDOException: SQLSTATE[HY000] [2002]來自MySQL連接上。

解決方法

在Drupal的默認settings.php文件中加入mysql 加入unix_socket。

array (
'database' => 'demo_drupal',
'username' => 'root',
'password' => '',
'host' => 'localhost',
'port' => '3309',
'unix_socket' => '/Applications/rubystack/mysql/tmp/mysql.sock',
'driver' => 'mysql',
'prefix' => '',
)

檢查drush是否正常工作，只需輸入drush status來讀取信息正常，就說明安裝成功了。

如下演示：

 Drush 升級 Drupal

使用drush up命令來升級drupal。
