Update about plugins directory
Upgrading¶
- Table of contents
- Upgrading
Step 1 - Check requirements¶
The first step to upgrading Redmine is to check that you meet the requirements for the version you're about to install.
Step 2 - Backup¶
It is recommended that you backup your database and file uploads. Most upgrades are safe but it never hurts to have a backup just in case.
Backing up the files¶
All file uploads are stored to the files/
directory. You can copy the contents of this directory to another location to easily back it up.
MySQL database¶
The mysqldump
command can be used to backup the contents of your MySQL database to a text file. For example:
/usr/bin/mysqldump -u <username> -p<password> <redmine_database> | gzip > /path/to/backup/db/redmine_`date +%y_%m_%d`.gz
SQLite database¶
SQLite databases are all contained in a single file, so you can back them up by copying the file to another location.
PostgreSQL¶
The pg_dump
command can be used to backup the contents of a PostgreSQL database to a text file. Here is an example:
/usr/bin/pg_dump -U <username> -Fc --file=redmine.sqlc <redmine_database>
A decent blog (self plug) can be found here: http://www.commandprompt.com/blogs/joshua_drake/2010/07/a_better_backup_with_postgresql_using_pg_dump/
Step 3 - Perform the upgrade¶
Now it's time to perform the actual upgrade. This process is different depending on how you downloaded Redmine. You only need to perform one of the following options.
Option 1 - Downloaded release (tar.gz or zip file)¶
1. Uncompress the new program archive in a new directory.
2. Copy your database settings-file config/database.yml
into the new config
directory. If you're running Redmine >= 1.4 with mysql and ruby1.9, change the database adapter to `mysql2`.
3a. Copy your base configuration settings-file config/configuration.yml
into the new config
directory.
3b. Or, if upgrading from version older than 1.2.0, copy your email settings from your config/email.yml
into the new config/configuration.yml
file that can be created by copying the available configuration.yml.example
file.
4. Copy the files
directory content into your new installation.
5. Copy the folders of your custom installed plugins from your vendor/plugins
directory (if upgrading from a version prior to 2.0.0) or plugins
directory (else, upgrading from a version >= 2.0.0) into new installation plugins
directory. Make sure that you copy only plugins that are were not initially bundled with your previous Redmine setup.
6. Run the following command from your new Redmine root directory:
rake config/initializers/session_store.rb
If you're using a newer version of Redmine, the above file will no longer exist. On these versions, run
rake generate_session_store
This will generate a file (config/initializers/session_store.rb
) with a random secret used to secure session data.
7. Check for any themes that you may have installed in the public/themes
directory. You can copy them over but checking for updated version is ideal.
VERY IMPORTANT: do NOT overwrite config/settings.yml
with the old one.
Option 2 - Upgrading from a SVN checkout¶
1. Go to the Redmine root directory and run the following command:
svn update
2. If you are upgrading from an older version to 0.8.7+ or from the trunk version of Redmine to r2493 or above, you must generate a secret for cookie store. See the note at the bottom about generating a session_store
.
Step 4 - Update the database¶
This step is the one that could change the contents of your database. Go to your new redmine directory, then migrate your database:
rake db:migrate RAILS_ENV=production
If you have installed any plugins, you should also run their database migrations. If you are upgrading from Redmine 0.8.x as part of this migration, you need to upgrade the plugin migrations first:
rake db:migrate:upgrade_plugin_migrations RAILS_ENV=production
rake db:migrate_plugins RAILS_ENV=production
Step 5 - Clean up¶
1. You should clear the cache and the existing sessions:
rake tmp:cache:clear rake tmp:sessions:clear
2. Restart the application server (e.g. mongrel, thin, passenger)
3. Finally go to "Admin -> Roles & permissions" to check/set permissions for the new features, if any.
Common issues¶
Errors with repository management¶
There were several new features added to the reposman.rb file, make sure you have a group specified if you're having issues ( --group=groupnamehere). Also, make sure you follow the instructions here again if you only copied your Redmine.pm, and update your Apache configuration as the recommended configuration has changed.
Generating a new session_store.rb
/ secret_token.rb
¶
Before 2.0.0, an session_store.rb
file needs to be generated in Redmine's config
directory for the cookie based sessions to work. Just run the following command and Redmine will create one for you:
rake generate_session_store
Starting from 2.0.0, it has been replaced by the following command that will generate the secret_token.rb
file:
rake generate_secret_token
Note: The code repository for Redmine does not contain the config/initializers/session_store.rb file, it is created by the above rake command. If the above command does not work, make sure you are running Ruby 1.8.7 and have Rails 2.3.x(see Error about the Rails version below).
Errors about a missing session_store.rb¶
If you see any errors about a missing session_store.rb
file, run the command above to create a new one.
Error about the Rails version¶
Remember to install the Ruby on Rails gem version required by the new Redmine version (1.2.x uses Rails 2.3.11, 1.3.x uses 2.3.14 etc.).
You might need to upgrade your Ruby on Rails gem, e.g.:
gem install rails -v=2.3.14
Error about member_roles¶
If you have had a failed upgrade/migration in the past then you may have a member_roles and/or group_users table already created. The db migration noted above will fail. Simply rename the tables by logging into MySQL command line and executing the rename table command:
mysql> rename table member_roles to member_roles_saved
mysql> rename table groups_users to groups_users_saved
Error about "undefined method `add_frozen_gem_path'"¶
If you see this error, check if the directory vendor/rails
exists and remove or rename it if it does, it might have an old RoR version.
