FreeBSD VPS v3 Release NotesIntroductionThis document is current as of 10/18/2006. Bugs, features, and considerations may be introduced after the creation of this document. FreeBSD VPS v3 customers and users should consult the product and support Web pages for the most current information about FreeBSD VPS v3.The FreeBSD VPS v3 (hereafter VPS v3) product includes upgrades from FreeBSD VPS v2 for several core services and programs. This document provides general information about the VPS v3, including what's new, differences between VPS v3 and VPS v2, and known issues. Document ContentsThis document contains three sections:
What's NewThe VPS v3 offers a large amount of disk space and contains many improved features, including upgrades to the operating system and file system, improvements in core services, programs and available installations, and improved Java support. The VPS v3 is available in three levels, or plans: Basic, 1000, and 2000.Disk SpaceThe disk space of VPS v3 plans has been increased to the following quotas:
Operating SystemThe introduction of VPS v3 upgrades the operating system controlling the server from FreeBSD 4.7 to FreeBSD 6.0. Advantages of FreeBSD 6.0 include the following:
File SystemThe file system of VPS v3 also moves from Unix File System 1 (UFS1) to Unix File System 2 (UFS2). This move increases speed, performance, and stability of the file system in general. Other advantages to UFS2 include the following:
Core ServicesNoteworthy changes to and information about core services include the following:
Programs and Available InstallationsMost programs currently available for installation on VPS v2 are available for VPS v3. Noteworthy changes and issues with programs and available installations include the following:
JavaThe VPS v3 includes support for the most current Java Developer's Kit (jdk) and Java Runtime Engine (jre). These features are available as vinstalls (java_jdk and java_jre) on VPS v3 2000 plans. The vinstall gives instructions for downloading the FreeBSD installation files from the FreeBSD Foundation Web site, and then uploading them to the VPS account.The Tomcat Web application server is also available with the VPS v3. Available through a vinstall, the Tomcat server can support several different kinds of Java applications, including servlets and JSP pages. Tomcat requires the installation of the Java Runtime Engine or the Java Developer's Kit and is available on VPS v3 2000 plans. Differences between VPS v3 and VPS v2This section includes a brief list of differences between VPS v3 and VPS v2. It discusses the most used and popular elements of the VPS server, including the Apache Web server, PHP, MySQL, and vinstall library, including updates to the WordPress vinstall.The VPS v3 is a significant upgrade to the VPS products. Because VPS v3 includes upgrades to the operating system and the file system, almost all programs and services on the server vary technically in some way from other VPS products. Accordingly, interaction with frequently used and common elements of the server may change. However, the VPS v3 operating system and file system perform almost identically to VPS v2. This means your interaction with most wrappers, scripts, services, and programs on VPS v3 should not change. For example, your usage of commandline wrappers such as vadduser or vaddhost does not change. Web ServerThe VPS v3 comes with the Apache Web server version 2.2.3 installed by default. This new version performs faster and executes requests in a more optimized fashion than previous versions. The Apache 2 Web server also provides native support for the increasingly popular IPv6 protocol. For more information about changes in version 2.x, visit the following Web page:http://httpd.apache.org/docs/2.0/en/new_features_2_0.htmlFor more information specifically about changes in version 2.2.x, visit the following Web page: http://httpd.apache.org/docs/2.2/en/new_features_2_2.html PHP 5.xPHP (PHP: Hypertext Preprocessor) version 5.1.5 is compiled specifically for Apache 2 on VPS v3. PHP 4.4.4, available through a vinstall, is compiled specifically for Apache 1. Attempting to use either version of PHP with a different version of the Apache Web server may cause scripts and programs to function incorrectly.PHP 5.x adds several new extensions and improved support for popular technologies such as XML, SOAP, MySQL, object oriented programming, and others. For more information about changes in PHP 5.x, visit the following Web page: http://www.php.net/ChangeLog5.php MySQL 5.xThe new operating system of the VPS v3 permits the MySQL database server to use native threading, instead of Linux threading as used with previous VPS implementations. MySQL for VPS v3 uses less (sometimes 30 or more) processes than MySQL on other VPS products!MySQL 5.0.24 is the default version installed when executing vinstall mysql or vinstall mysql5 from the command line. MySQL 4.1.21 is also available by executing vinstall mysql4.1 from the command line. MySQL 5.x includes many new controls, elements and features, improving performance and functionality. For more information about changes in MySQL 5.x, visit the following Web page: http://dev.mysql.com/doc/refman/5.0/en/index.html Vinstall LibraryThe VPS v3 introduces several new vinstalls, such as Tomcat and java_jdk. Old or deprecated programs in the vinstall library are no longer offered. The vinstalls offered on VPS v2 that are not supported on VPS v3 include the following:
WordPressThe vinstall for WordPress for VPS v3 installs the latest WordPress version, 2.0.4. The vinstall also provides additional commandline options when installing WordPress. To obtain a full list of these options, connect to your server through SSH and execute the following from the command prompt:# vinstall wordpress help An example of these new options is you can specify the installation of a language pack for WordPress during the vinstall. For example, the following installs the Japanese language pack: # vinstall wordpress lang='ja' Known IssuesThis section contains information about backward compatibility of core services and the interaction of popular applications with the versions of those services available for VPS v3, and corresponding applications available for VPS v2. It also contains considerations when migrating from VPS v2 to VPS v3 and other existing issues.Backward CompatibilityWith the introduction of new versions of Apache, MySQL, and PHP, some elements of these new versions may not be compatible with older versions available with other VPS products, such as the VPS v2. Considerations for these services and programs follow.ApacheWith Apache 2, the module interface has completely changed. Because of this, modules used with Apache 2 differ from their Apache 1 counterparts. Scripts and programs written to interact with modules in Apache 1 may not function the same when interacting with the corresponding module for Apache 2. For example, Apache 2 includes support for mod_perl2 instead of mod_perl, the default for previous VPS implementations. Compatibility modules may be available for a specific Apache 1 module. Consult the documentation for the module in question for further information about backwards compatibility of that module.Apache 2 also introduces some configuration directives changes. For more information about directives changes, refer to the Web addresses mentioned in "Web Server" on page 4. MySQLSQL syntax used in 4.x should function correctly in MySQL 5.x. However, it is always best to perform a full database dump on the system running under 4.x and then import the information in the 5.x system to ensure data is not corrupted. Other considerations when moving between MySQL versions 4.x and 5.x include the following:The format of the standard "mysql" database (which keeps user and other essential information) has changed. Support for some old types of tables has been discontinued. Multibyte support changed with 4.1x and may be significantly different. For more information about changes in MySQL 5.x, refer to the Web address mentioned in "MySQL 5" on page 4. PHPMost scripts and programs created for PHP 4.x should function with PHP 5.x. Verify that scripts and programs function correct when moving from a PHP 4.x environment to PHP 5.x.The short tags configuration is disabled by default for PHP 5.x. This can be enabled in the /usr/local/lib/php.ini file. Migration ConsiderationsAutomated scripts to move sites or content from a different VPS product to the VPS v3 will be available at a later date. Customers interested in migrating their sites and content must create any such scripts or perform such activities themselves at this time.Other IssuesThe following issues also exist for VPS v3 as of 10/18/2006:For the CPX Control Panel, on the Manage Services section of the System Administration module, the httpd service shows a status of stopped when the service is running. |
