Lunarpages空间服务商的数据库升级

刚才收到Lunarpages空间服务商的邮件通知,说将在太平洋时间2012年5月10日中午12点把数据库服务器的MySQL从5.0升级到5.1。不知道这会不会对我的博客有什么影响。邮件中还强调了新版本的MySQL用户名限制在16个字符内,多出的会被自动截断,这会对部分超出16个字符用户名的客户造成影响。我检查了一下我的用户名长度,还好在16个字符内,希望这次数据库的升级不会对我的博客有什么影响。具体的邮件内容如下:

Dear Customers,

We will be updating MySQL from version 5.0 to version 5.1 on your database server LPSQL04 on 10th May 2012 12AM Pacific time. We have backups on hand for all databases in the event of any issues with the upgrade process.

Please note MySQL prior to 5.1 has limited usernames to 16 characters. In those versions of MySQL, when a login username longer than 16 characters is sent to the server it is silently truncated to the 16 characters limit. In MySQL 5.1, all characters submitted for the username are checked during authentication. This change means that any user submitting more than 16 characters as their login username will fail to authenticate once the server is upgraded. To ensure the upgrade goes smoothly for you, if your sites use database logins longer than 16 characters, please correct database connection details to only send the first 16 characters of the current login usernames by truncating them.

If you have any questions about this update, please contact support@lunarpages.com

Thank you,
Lunarpages Webhosting System Administrator Team
