| == Make a backup == | | == 做好备份== |
| The upgrade process should be very safe. But just in case, it's a very good idea for you to make a backup. So before you perform this upgrade you should [[Gallery:How_do_I_Make_Backups_of_My_Database|backup the database]] just in case. If something goes wrong you can always restore the database and try again. If you've made modifications to your copy of the Gallery 2 code, you should back up your changes also in case the update overwrites some of them.
| | 升级过程应该是相当安全的。但有备无患，做好备份绝不是多余之举。因此在执行升级之前，你应当 [[Gallery:How_do_I_Make_Backups_of_My_Database|备份数据库]]。一旦发生不测你可以随时回复数据库并重试。如果你对Gallery2代码拷贝做了修改的话，就应该对修改做备份以防更新过程会进行重写。 |

| There are three ways to upgrade:
| | 有三种方法可以进行升级： |
| # [[Gallery:Upgrading#Replace_all_files|Replace all files]]: Download a complete replacement for your Gallery 2. This is slower, but very reliable. | | # [[Gallery:Upgrading#替换所有文件|替换所有文件]]：下载整个Gallery2的完整替代。这回比较慢，但是很可靠。 |
| # [[Gallery:Upgrading#Use_an_update_file|Use an update file]]: Replace only what's changed since the major release. This option is only available for security & patch releases. If you've modified your Gallery 2 code, this technique can preserve your changes. It's faster than a complete replacement, but takes a little more know-how. | | # [[Gallery:Upgrading#使用更新文件|使用更新文件]]：仅替换自主要版本发布以来的修改内容。此选项仅对安全性&补丁发布可用。如果你修改了Gallery2代码，此方法将保留你所作的修改。此方法比替换所有文件的方法要快，但是需要了解相关的知识。 |
| # [[Gallery:Upgrading#Update_from_Subversion|Update from Subversion]]: This is the best approach if you've made changes to your Gallery 2 code. It's relatively fast and won't step on any changes you've made, but it requires a lot of know-how and is not available to most people. | | # [[Gallery:Upgrading#由Subversion进行更新|由Subversion进行更新]]：如果你对Gallery2代码做了修改，那么这就是最好的办法了。此方法相对较快并且不会牵扯进你所作的修改，但是需要极为熟悉相关的知识，因此对于大部分用户来说，这个方法并非那么容易就能掌握的。 |
|
| |
|
| === Replace all files === | | ===替换所有文件=== |
| [[Gallery:Download#Packages Download a complete new copy of Gallery 2]] and simply unpack it on top of your existing Gallery 2 install and then run the upgrader. This is a simple and thorough but slow method. Also, any modifications that you've made to Gallery 2 '''will be lost''' when you replace the files, with the exception of template changes made in ''local'' directories. | | [[Gallery:Download#整合包 下载全新Gallery2拷贝]]并直接将其解压到现有的Gallery2安装之上，然后运行升级程序。此方法简单并且彻底，但速度就比较慢了。另外，你对Gallery2所作的所有修改将在文件被替换之后'''丢失'''，但在''本地''目录中所作的模板改动不会受影响。 |

|
| |
|
| == Major Releases == | | == 主要发布版本 == |
| 2.0 was the first official release of Gallery 2. Gallery 2.1 followed about half a year later, followed by 2.2, etc. These are major releases of Gallery which come with new and improved features and a lot of smaller and bigger bugfixes. | | 2.0是Gallery2的第一个官方发布版本。Gallery 2.1的发布约是半年之后，接着是2.2。这些都是Gallery2的主要发布版本，它们都带有新且经改良的特点以及或大或小的bug修正。 |
|
| |
|
| Please note that Gallery 2.3 will be the last major release to be compatible with PHP 4 ''and'' PHP 5. Gallery 2.4 will only support PHP 5 and later. Related announcement: [http://gallery.menalto.com/gallery_2_and_php5 Gallery requiring PHP 5 by the first major release in 2008].
| | 请注意Gallery 2.3将会是最后一个能与PHP4和PHP5兼容的主要发布版本。Gallery 2.4起将仅支持PHP5。相关的公告：[http://gallery.menalto.com/gallery_2_and_php5 2008年首次发布的Gallery版本需要PHP5的支持]。 |
|
| |
|
| You should subscribe to the [[Mailing_Lists|announcements mailing list]] to get notified about all important updates.
| | 你应当订阅 [[Mailing_Lists|公告邮件发送列表]]来获取所有重要更新的相关信息。 |
|
| |
|
| == Security and Patch Releases == | | == 安全性及补丁发布 == |
| In case we announce a security vulnerability patch release, you should upgrade your installation as fast as possible to ensure that it is protected from all known vulnerabilities.
| | 如果我们发布了安全性漏洞补丁的话，你应当尽快进行升级以保证其不受攻击。 |
|
| |
|
| Security upgrades can be easily identified by the version number. All Gallery 2 version numbers follow the x.y.z scheme. 'x' is obviously always '2'. 'y' changes on major releases. And 'z' changes on security and patch releases.
| | 安全性升级可通过版本号轻易地辨别出来。所有的gallery2版本号都遵循x.y.z的形式。'x'肯定总是'2'。'y'随着主要（较大）更新而改变。而'z'则是安全性及补丁更新。 |
|
| |
|
| We try to keep the number of security & patch releases as small as possible, usually only to address an important security vulnerability or if there was a very important bug that slipped through our thorough release testing and quality assurance.
| | 我们努力保证安全性及补丁的发布处于最小限度，通常只有重要的安全性漏洞补丁或经测试及质量测评认可的重要bug才会考虑发布。 |
|
| |
|
| This is why security releases only contain a very small set of changes confined to the very problem that needed to be addressed. You will not get other bugfixes and new features since the last major release when doing a security upgrade. But that also means that the number of files to upload is very small in this case. Security upgrades are very quick and easy.
| | 这就是安全性更新仅包括具有针对性的问题修复的原因了。在安全性升级时，你不会获得其他的bug修复及新特色。但这也意味着要重新上传的文件量不会太大。因此安全性升级既快又简单。 |
|
| |
|
| Also note that the latest stable release always includes all security fixes and patches.
| | 还需注意最新的稳定发布版本总是包括了所有的安全性修复及补丁。 |
|
| |

| == Upgrading To Nightly Snapshots And Development Versions == | | == 升级到nightly快照版和开发版本 == |
| Gallery 2 is managed in a central source code repository and we refer to the current state of this repository as the 'development version' of Gallery 2. Gallery developers strive to keep this development version as stable as possible.
| | Gallery2是在一个中央源代码存储库中进行管理的，我们则将该存储库当前状态理解为Gallery2的'开发版本'。Gallery开发者们正努力保证此开发版本的稳定性。 |
|
| |
|
| A '''nightly snapshot''' is a packaged copy of the current development version of Gallery which is at most 24 hours old.
| | '''nightly snapshot'''则是Gallery当前开发版本的拷贝整合包，它是很“新鲜”的，从发布开始不会超过24小时。 |
|
| |
|
| Although some quality assurance testing is done permanently, there is a reason why we recommend the latest official release and not the development version to our users. The latest development version might have new features you're anxious to use on your website, but much more testing, auditing and quality assurance is done for official releases than during development.
| | 尽管某些质保测试是定期的，但我们向用户推荐使用最新官方版本而不推荐开发版本是有原因的。最新的开发版本可能具有的新特点会让你觉得不便于用在网站上，而很多测试，修改，质保存是都是针对官方正式发布版本进行的，开发版本则很少被顾及到。 |
|
| |
|
| Nevertheless, there are people that appreciate the high quality of the the development version and actually use it on their own production server. And sometimes, we will recommend the nightly snapshot to specific users because they might suffer from a specific problem that has been addressed since the last official release.
| | 然而，还是有人欣赏开发版本较高的品质，而且真正用在了服务器上。而某些时候我们会对特定用户群推荐使用nighly snapshot，因为这些人可能正受自上个正式版本发布以来某特定问题的困扰。 |
|
| |
|
| Upgrading from and to nightly snapshots and development versions is the same as with official releases.
| | nightly snapshot和开发版本的升级跟官方正式版本的并无二致。 |
|
| |
|
| Note: You can also use the [[Gallery:Preinstaller#Upgrading|Pre-Installer]] to upgrade to a nightly snapshot.
| | 注：你还可以使用 [[Gallery:Preinstaller#升级|Pre-Installer]]来升级到某个nightly快照版。 |

|
| |
|
| == Upgrading an Integrated Gallery == | | == 整合Gallery的升级== |
| In case your Gallery is integrated in another application (CMS, blog, portal, forum, ...), you first need to ensure that the new Gallery version is compatible with the other application. Also, you should check if there is an updated integration available for your specific application. Best is you consult the [[Gallery:Integration:Available_Integrations|project website of the specific integration]].
| | 如果你的Gallery是被整合到另一个应用程序（CMS，blog，门户，论坛等）中的话，那么首先你需要确保新的Gallery版本与其他的应用程序相兼容。另外你还得查看一下是否有对应你所使用的应用程序的更新整合。最好参考一下 [[Gallery:Integration:Available_Integrations|特定整合的项目网站]]。 |

更新既快又简单，只需数分钟即可完成。
做好备份[ ]
升级过程应该是相当安全的。但有备无患，做好备份绝不是多余之举。因此在执行升级之前，你应当 备份数据库。一旦发生不测你可以随时回复数据库并重试。如果你对Gallery2代码拷贝做了修改的话，就应该对修改做备份以防更新过程会进行重写。
- 接下来： 识别你的Gallery2版本
识别你的Gallery2版本[ ]
为了能够进行升级，你需要了解你当前所使用Gallery2的版本。在浏览器中打开Gallery2，以管理员身份登入，点击"站点管理（Site Admin）"链接，接着点击"维护（Maintenance）"链接。现在你就会看到一个罗列有维护任务的列表了。在每个任务的旁边标记有系统信息（System Information），点击现在运行（run now）链接，接着查找标有Gallery version的一行。
- 接下来： 回顾发布版本注解和已知问题
回顾发布版本注解和已知问题[ ]
在开始升级之前，你需要回顾一下最新Gallery2版本注解并浏览一下已知问题。
Gallery2的要求（比如要求PHP达到某个版本）可能会改变或者是可能对应你进行的安装可能会有问题记载。
- 接下来： 升级应用程序文件
升级应用程序文件[ ]
有三种方法可以进行升级：
- 替换所有文件：下载整个Gallery2的完整替代。这回比较慢，但是很可靠。
- 使用更新文件：仅替换自主要版本发布以来的修改内容。此选项仅对安全性&补丁发布可用。如果你修改了Gallery2代码，此方法将保留你所作的修改。此方法比替换所有文件的方法要快，但是需要了解相关的知识。
- 由Subversion进行更新：如果你对Gallery2代码做了修改，那么这就是最好的办法了。此方法相对较快并且不会牵扯进你所作的修改，但是需要极为熟悉相关的知识，因此对于大部分用户来说，这个方法并非那么容易就能掌握的。
替换所有文件[ ]
Gallery:Download#整合包 下载全新Gallery2拷贝并直接将其解压到现有的Gallery2安装之上，然后运行升级程序。此方法简单并且彻底，但速度就比较慢了。另外，你对Gallery2所作的所有修改将在文件被替换之后丢失，但在本地目录中所作的模板改动不会受影响。
注：
- Pre-Installer也可用于新版本至网站的快速上传。
- Gallery2整合包有四类（典型，最小，完整以及开发者）。你所下载的整合包类型应当与你之前所用的类型相同。
- 接下来: 运行基于web的升级程序
使用更新文件[ ]
首先确定实际的Gallery版本--Gallery 2.x.y（如Gallery 2.2.1）。
更新文件仅对如下版本可用：
由Subversion进行更新[ ]
如果你是自 Subversion 进行Gallery2安装的话，你可以直接运行：
svn update
这将会为你获取原先进行check out区域的最新代码。如果你check out BRANCH_2_2那么将会取得最新2.2.x版本，而如果是trunk的话，结果就会是最新的开发代码。
- 接下来: 运行基于web的升级程序
运行基于web的升级程序[ ]
一旦你的文件更新完了，在web浏览器中打开Gallery2，就会自动引导至升级程序。请按照如下指导操作。
在升级程序进行到第二步时，Gallery文件完整性检查应当显示成功。如果有列出缺失/被删除/被篡改的文件的话，你应当确保是你自己在拷贝中对这些文件做了修改。如果报告自modules/core/test目录有超过100个缺失文件的话，请确认你没有无意间将被修改文件的开发者整合zip安装至某源自最小化，典型或完整版本上。如果确实发生了这种情况，没关系！请返回并获取正确的zip文件，接着重试即可。
注：
- 如果你使用PHP 加速器/缓存（如Turk mmCache，Ioncube PHPA，eaccelerator，Zend Studio等）请清除加速器的缓存。忽略此步骤的话有时会导致等级过程中或升级完成后出现错误。
- 如果尚未进行此操作的话，那么请你在升级核心模块之前备份Gallery！
成功完成之后，你就会回到最新版本的Gallery2中，万事大吉了。

你应当订阅 公告邮件发送列表来获取所有重要更新的相关信息。
安全性及补丁发布[ ]
如果我们发布了安全性漏洞补丁的话，你应当尽快进行升级以保证其不受攻击。
安全性升级可通过版本号轻易地辨别出来。所有的gallery2版本号都遵循x.y.z的形式。'x'肯定总是'2'。'y'随着主要（较大）更新而改变。而'z'则是安全性及补丁更新。
我们努力保证安全性及补丁的发布处于最小限度，通常只有重要的安全性漏洞补丁或经测试及质量测评认可的重要bug才会考虑发布。
这就是安全性更新仅包括具有针对性的问题修复的原因了。在安全性升级时，你不会获得其他的bug修复及新特色。但这也意味着要重新上传的文件量不会太大。因此安全性升级既快又简单。
还需注意最新的稳定发布版本总是包括了所有的安全性修复及补丁。
如果你已有某Gallery2特定版本而需要安装安全性补丁的话，请参见：使用更新文件
升级到nightly快照版和开发版本[ ]
Gallery2是在一个中央源代码存储库中进行管理的，我们则将该存储库当前状态理解为Gallery2的'开发版本'。Gallery开发者们正努力保证此开发版本的稳定性。
nightly snapshot则是Gallery当前开发版本的拷贝整合包，它是很“新鲜”的，从发布开始不会超过24小时。
尽管某些质保测试是定期的，但我们向用户推荐使用最新官方版本而不推荐开发版本是有原因的。最新的开发版本可能具有的新特点会让你觉得不便于用在网站上，而很多测试，修改，质保存是都是针对官方正式发布版本进行的，开发版本则很少被顾及到。
然而，还是有人欣赏开发版本较高的品质，而且真正用在了服务器上。而某些时候我们会对特定用户群推荐使用nighly snapshot，因为这些人可能正受自上个正式版本发布以来某特定问题的困扰。
nightly snapshot和开发版本的升级跟官方正式版本的并无二致。
注：你还可以使用 Pre-Installer来升级到某个nightly快照版。

参见：如何升级一个多站点
整合Gallery的升级[ ]
如果你的Gallery是被整合到另一个应用程序（CMS，blog，门户，论坛等）中的话，那么首先你需要确保新的Gallery版本与其他的应用程序相兼容。另外你还得查看一下是否有对应你所使用的应用程序的更新整合。最好参考一下 特定整合的项目网站。
除此之外，升级过程与独立的或一般的Gallery2升级过程是一样的。
