TEMPEST planned move - 7th of April 2016
« on: March 31, 2016, 05:55:18 AM »
Dear Customer,

TEMPEST will begin a planned move to a new server on 7th of April 2016. This move will be to upgrade the server operating system from CentOS 4, which has been phased out for support, to CentOS 6.x. The exact time and date for the switch to the new hardware will be announced through the 'Network Status' section of your https://account.lunarpages.com account at least 24 hours in advance, after the first phase of the data copy process has been done. You will experience no downtime during this process, although we do suggest no significant changes be made to your site after you receive the second announcement.

The upgrade will add a serious of improvements and we will also be updating MySQL from the version tree 5.5 to version 5.6 as well as the Apache version to 2.4 and the PHP releases to 5.6 on the server. The latest releases available within the stable branch will be used.

In order to ensure the upgrade goes smoothly please review your sites for compatibility with PHPs 5.6.x branch. Incompatibilities between PHPs versions 5.3, 5.4 and 5.5 can be found through the URLs below:

http://php.net/manual/en/migration54.php
http://php.net/manual/en/migration55.php
http://php.net/manual/en/migration56.php

Please note that the deprecated PHP releases (5.2.x, 4.4.x) will be removed entirely.

We have backups on hand for all databases in the event of any issues with the upgrade process. For more details on MySQL and specifically MySQL 5.6 series, please review the changelog at http://dev.mysql.com/doc/relnotes/mysql/5.6/en/index.html.

Most scripts should run normally without issues on MySQL 5.6, however this will also imply having MySQL-dependent connectors such as python, java or the ruby gem updated, so if you are running any scripts which are older or not up-to-date, please ensure to obtain the most current copy of the script from the script development site so that the script will function properly with the new MySQL 5.6 release. The changes in the MySQL 5.6 release are listed at http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-16.html.

MySQL users that were last updated more than approximately 6 months ago are likely using the 16 bytes (old, deprecated) password hash, so if your script can not establish the connection with the database once MySQL gets upgraded you'll need to consider doing the following:
1) Change your CPanel password if you use the CPanel username for ANY mysql connections (it doesn't matter to what - you can even set the same one, however it'll be picked up in a 41 bytes hash once you do it);

2) Change your MySQL users password if you haven't done so in the past ~6months for every user that you use (and delete the users that are unused) - this can be done from CPanel -> MySQL databases -> Clicking on the mysql user and filling the needed fields. Sometime you need to remove mysql user and re-add same user and password and allow mysql grant privileges else your site will show database connection issue.

Please note that you may check the current status for this server at any time in CAP via https://account.lunarpages.com/ with your cPanel username and password, then by clicking the Network Status icon. Additionally, the move will result in completely giving up on the FrontPage extensions, which are now deprecated and have been replaced with WebDAV.

Thank you for your patience and we apologize for any inconvenience in the interim. If you have any issues with your site, please contact support@lunarpages.com
