General settings

Administrators can access various global level application settings found at Administration -> Settings.

General tab

  • Application title
    Title which appears in heading of the application. This is the label just under the top menu bar, next to the Redmine logo (while within a project, the project name is displayed there instead).
  • Welcome text
    Text displayed on the home page of Redmine.
  • Objects per page options
    Here you can configure the fixed values which users can select for the amount of objects (issues, commits etc.) which are displayed per page. Default: 25, 50, 100
  • Search results per page
    The number of search results which are displayed per page. Default: 20
  • Days displayed on project activity
    The amount of days of which the project(s) activity is shown per page in the activity tab.
  • Host name and path
    Host name and path of your Redmine server. This name is used to write URL in emails sent to users. i.e.: the hostname of this precise Redmine is

    Redmine guesses the value of this setting and displays it as an example below the text box. The guessed value is appropriate for your Redmine server in most cases.
  • Protocol
    Protocol used to generate links in email notifications. Default: http

    Links in email are "guessed", but can't determine whether you're using an unsecured web server (http) or a secure one (https -> http over SSL).

Note: It is very important to store proper Host name, path and Protocol because some parts of Redmine and some of the plugins use it to build links to other components of Redmine. For example, it can be used in some Edit links, or to create a return address after a form is saved.

  • Text formatting
    Formatting method applied to the "description" fields of the issues, news, documents...

    You can select Textile (default) or Markdown.
  • Cache formatted text
    Text formatting transforms raw text to HTML and runs each time a formatted text is sent to a user's browser (eg. issue description, wiki page...), and this process can be slow with large pages or texts.

    This setting lets you enable caching of formatted text.

    The storage to be used to store cached data depends on the configuration of a cache store. The default cache store is FileStore. It stores cached data as files in tmp/cache directory.

    You can configure to change the cache store to other one such as MemoryStore and MemCacheStore by adding a setting like config.cache_store = :memory_store to your config/environments/production.rb, for example
Rails.application.configure do
  # Settings specified here will take precedence over those in config/application.rb

  config.cache_store = :memory_store

You can read more about cache stores in the Rails guides.
  • Wiki history compression
    Lets you activate compression for wiki history storage (reduces database size). Default: disabled

    • Session inactivity timeout: Lets the administrator specify after how many hours of inactivity the session times out.

Note: Changing these settings may expire the current sessions (including your own).

Note: Redmine uses the rails cookiestore for session management. We strongly advise you to set a maximum session lifetime. If you don't, it is theoretically possible that an attacker steals the session cookie and re-uses it.

Issue tracking tab

  • Allow cross-project issue relations
    If set to Yes, relations between issues from different projects can be created. Default: No
  • Link issues on copy
    Depending on this option, a copied Issue will contain a link to the original one. If this is set to "Ask", upon copying the user will have the option to choose
  • Allow cross-project subtasks
    Define some limits for subtasking. Definitions used are the same as version sharing, documented in Redmine Project Settings.

    • With all projects: a parent task can have subtasks in any other project.
    • With project tree (default): a parent task can have subtasks in the same project, ancestor projects and all their descendants (e.g. also "sibling projects", "cousin projects", etc.).
    • With project hierarchy: a parent task can have subtasks in the same project, subprojects, or ancestor projects.
    • With subprojects: a parent task can only have subtasks in the same project or subprojects (not in parent projects or unrelated projects).

  • Emails footer
    Here you can enter some text that will be appended to the emails sent by the application.

Incoming emails tab

For detailed instructions about these settings refer to Redmine Receiving Emails.

  • Truncate emails after one of these lines
    Use this setting to remove signatures from incoming emails. You can also check "Enable regular expressions" and use regular expressions to specify sets of lines at once.
  • Exclude attachments by name
    Use this field to create a blacklist for attachments that will be removed from the message.
  • Enable WS for incoming emails
    Redmine can be configured to allow issue creation or comments via email. In order to use that feature, you have to enable the API that receives emails. That is where this setting is for. A description of the setup can be found here. Default: Off
  • Incoming email WS API key
    Here you can generate a secret key used for the issue creation or comments via email feature.

Repositories tab

  • Enabled SCM
    Here you can (de)select the SCM-systems Redmine should "provide" to the individual projects. This setting is useful if you only support several SCM-systems (e.g. only Git or only SVN).
  • Fetch commits automatically
    If this option is activated, the application automatically retrieves the new revisions when a user consults the repository. Default: Yes

    You can disable this option and automate the call to Repository#fetch_changesets using cron to regularly retrieve the revisions for all of the repositories in the background.

    ruby script/runner "Repository.fetch_changesets" -e production

    For Redmine 2.x:

    ruby script/rails runner "Repository.fetch_changesets" -e production

    For Redmine 3.x:

    bin/rails runner "Repository.fetch_changesets" -e production
    You can also call this task from your repository in a post-commit or post-receive hook, so that changesets are fetched after each commit. Here is a tutorial for doing so with git.
  • Enable WS for repository management
    This option should be activated only if you installed the script for automatic SVN repository creation. Default: No
  • Repository management WS API key
    A secret key for repository management WS.
  • Maximum number of revisions displayed on file log
    It provides a way to limit the amount of revisions which are retrieved from the SCM for a certain, browsed path.
  • Apply text formatting to commit messages
    Use this to enable 'wikification' of commit messages.
  • Referencing and fixing issues in commit messages
    When fetched from the repositories, commit messages are scanned for referenced or fixed issue IDs. Here you can define keywords that can be used in commit messages to reference or fix issues automatically, and the status to apply to fixed issues. Also spent time can be reported to Redmine through these messages.
    • Referencing keywords
      Default keywords are: refs, references, IssueID
      If you want to reference issues without using keywords, enter a single star: * in the Referencing keywords setting. In this case, any issue ID found in the message will be linked to the changeset.

      Example of a working commit message using default keywords:

      This commit refs #1, #2 and fixes #3

      This message would reference issues 1 and 2 and automatically fix issue 3. After a keyword issue IDs can be separated with a space, a comma or &.

      The keywords are case insensitive and at least one blankspace or colon is needed between the keyword and the first hash to produce a match. More examples that will produce the same result as the example above:

      This commit refs:#1, #2 and fixes #3
      This commit Refs  #1, #2 and fixes #3
      This commit REFS: #1, #2 and fixes #3
    • Allow issues of all the other projects to be referenced and fixed
    • Enable time logging
      Allows time logging directly from commit messages. This only makes sense if you activated the "Time tracking" module in said project. In this case, you can add special words in your commit message to indicate the time you spent on an issue.

      The basic syntax for doing that is : @<time>, where time consists in a number of hours or minutes.

      Here's a list of many valid commit messages that would work if you want to say you spent N hours on issue 1234:
      Implement feature #1234 @2
      Implement feature #1234 @2h
      Implement feature #1234 @2hours
      Implement feature #1234 @15m
      Implement feature #1234 @15min
      Implement feature #1234 @3h15
      Implement feature #1234 @3h15m
      Implement feature #1234 @3:15
      Implement feature #1234 @3.25
      Implement feature #1234 @3.25h
      Implement feature #1234 @3,25
      Implement feature #1234 @3,25h
    • Activity for logged time
      This is the type of activity that should be used when detecting there's a log time in a commit message (see above).
    • Table for specifying Fixing keywords
      If you want to enable the manipulation of issue statuses through commit messages, you have to specify what keywords result to what status for what tracker.

      For example, if there is a line where Tracker is set to "all", Fixing keywords to "fixes,closes", Applied status to "Resolved" and % Done to "100%", a message containing closes #1234 will set the status of issue 1234 to "Resolved" and % Done to 100%, regardless of what tracker it belongs to.
