問題

注意：本文中所描述的問題是由來自 Atomic repository的 MySQL更新引起的，因此在執行修復之前請務必啟用 Atomic repository：

# yum repolist

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

* atomic: www4.atomicorp.com

更新后MySQL無法啟動。

在 Plesk中會顯示以下錯誤信息：

Error in Plesk:

ERROR: PleskFatalException

Unable to connect to database: mysql_connect() [

href='function.mysql-connect'>function.mysql-connect

]: No

such file or directory

0: common_func.php3:153

psaerror(string

'Unable to connect to database: mysql_connect() [

]: No

1: auth.php3:116

或

Additionally, an exception has occurred while trying to report this error: Zend_Exception

在 /var/log/mysqld.log中沒有記錄。

原因

Atomic發行了損壞的mysql包到其 repositories中。在更新過程中 mysql安裝包會被更新，但是卻未創建所需的目錄 /var/lib/mysql-files。

解決方案

此問題已被Atomic通過 5.5.54-1199版本的 mysql-server包進行修復。請將包更新到最新版本：

# yum update mysql-server

如果沒有標記要更新的包，請清除 yum緩存：

# yum clean all

# yum update mysql-server
