升级向导

  • 确保iTop配置文件(在conf/production中为config-itop.php)不是只读的,
  • 将您的Web浏览器指向http(s)::: location_of_itoppsetup,然后按照屏幕上的说明进行操作。

一步一步安装向导 应用可重复用于升级,但有一些区别。

第一步检查配置的一致性以及MySQL,PHP和可选PHP扩展的先决条件。它在升级期间可能会失败,因为它比以前的版本更具限制性。
例如,在2.5.0之后,MySQL和PHP的前提条件将是变更。

Step 1: Configuration check

更新的第二步,汇总了先前在与数据库连接有关的设置中已经提供的信息,并默认建议在应用和数据库数据库之前创建iTop备份。

Step 2: Install or upgrade

升级的第三步提示您输入一些杂项信息,这些信息在升级期间仍可以更改:

Step 6: Misc parameters

升级向导的以下步骤允许您添加模块,但不能更改删除已选择的模块。

配置CMDB

您无法删除安装在以下位置的模块最初设定 但您可以添加一些。

Step 8

配置服务管理

在大多数情况下,该设置为最初设定 时间,不能改变

Step 9

配置工单管理

如果现在使用需要在iTop中管理工单,请检查安装 有关可能的选择。
一旦在先前的安装程序中做出选择,就无法在兼容Simple和I​​TIL的工单管理之间切换,也不能禁用工单管理模块。

您可以在此处启用增强客户门户。

Step 10

配置变更管理

如果现在使用需要管理iTop中的更改,请检查安装 有关可能的选择。
一旦在先前的安装程序中做出选择,就无法在兼容Simple和I​​TIL的变更管理之间切换,也不能禁用变更管理

Step 11

额外的ITIL流程

您无法删除安装在以下位置的模块最初设定 但您可以添加一些。

Step 12

附加模块扩展

如果添加了Modules/Extensions,则可以在升级流程的此步骤中安装但不能删除它们。

Step Extensions

一个扩展由一个或多个模块组成。
一个模块可以是多个扩展公用的。

启动安装

做出所有选择后,将显示总结。您可以通过单击每个部分的“加号”按钮来向下钻取以检查您的选择。

要启动iTop的实际升级,请单击“安装!”。按钮。

Step 13

升级的进度通过移动进度条显示。

Step 14

在此阶段,例如,当选择了不兼容的模块时,可能会显示错误消息。

完成升级(在此请求备份)后,您将获得:

Step 15

恭喜,您已成功升级iTop!

内部构造

在安装程序开始时,iTop将通过 <itop>/data.下名为.readonly的文件以只读方式移动。应用不再可写,因为可能会大大修改数据库结构。
然后,在数据模型编译期间,通过位于同一位置的名为.维护的文件,iTop移至维护模式。因为在此阶段中,即使在读取模式下也不再可以使用有效的iTop代码。
该机制适用:

  • 在安装程序上
  • 当iTop Hub推送扩展程序时,
  • 当ITSM Designer推送新数据模型时(针对Combodo的客户)
  • 在应用升级上。

Update wizard

  • Make sure that the iTop configuration file (config-itop.php in conf/production) is not read-only,

  • Point your web browser to http(s)://location_of_itop/setup and follow the on-screen instructions.

The step by step wizard to install the application is reused for an upgrade with a few differences.

The first step checks the consistency of the configuration and the prerequisites for MySQL, PHP and optional PHP extensions. It may fail during an upgrade as it can be more restrictive than it was in a previous version.
For example after 2.5.0, prerequisites on MySQL and PHP will change.

Step 1: Configuration check

The second step of the update, summarized information already provided in a previous setup related to database connection and propose by default to create an iTop backup before the application and database upgrade.

Step 2: Install or upgrade

The third step of an upgrade prompts your for several miscellaneous information which can still be changed during an upgrade: Step 6: Misc parameters

The following steps of the update wizard allow you to add modules, but you cannot change/remove already selected ones.

Configuring the CMDB

You cannot remove modules installed at initial setup but you can add some.

Step 8

Configuring Service Management

In most cases, that has been set at initial setup time and can not be changed

Step 9

Configuring Tickets Management

If you now wants to manage Tickets in iTop, check the install for possible options.
You cannot switch between Simple and ITIL Compliant Ticket Management once a choice has been made in a previous Setup, nor dis-activate the Ticket Management module.

You can enable here the Enhanced Customer Portal.

Step 10

Configuring Change Management

If you now wants to manage Changes in iTop, check the install for possible options.
You cannot switch between Simple and ITIL Compliant Change Management once a choice has been made in a previous Setup, nor dis-activate the Change Management

Step 11

Additional ITIL processes

You cannot remove modules installed at initial setup but you can add some.

Step 12

Additional Modules/Extensions

If you have added Modules/Extensions, they can be installed but not removed, at this step of the upgrade process.

Step Extensions

An extension is made of one or multiple modules.
A module can be common to multiple Extensions.

Launching the installation

Once all the choices are made, a summary is displayed. You can drill down to check your choices by clicking on the “plus” button for each section.

To start the actual upgrade of iTop, click on the “Install !” button.

Step 13

The progress of the upgrade is displayed with a moving progress bar.

Step 14

At this stage, error messages might be displayed when incompatible modules are selected for example.

Once the upgrade is done (here with a backup requested) you get:

Step 15

Congratulation, you’ve successfully upgraded iTop!

Internals

At the beginning of a Setup, iTop is moved in read-only, by the means of a file named .readonly under <itop>/data. Application is no more writable, as the database structure might be drastically modified.
Then during the datamodel compilation, iTop is moved to maintenance mode, by the means of a file named .maintenance in the same place. Because during this phase there is no more a valid iTop code which could be used, even for a read mode.
This mechanism applies:

  • on Setup,

  • when iTop Hub pushes an extension,

  • when the ITSM Designer pushes a new datamodel (for Combodo's customers)

  • on an Application upgrade.
