Upgrade Redmine+Agile

It is strongly recommended that you create a backup before starting the update process. If you have important data, it is advisable that you create and try to restore a backup to ensure that everything works properly.

Upgrade Redmine and all stack components (recommended)

You can upgrade the application and the stack components by following the steps below:

• Launch a new Redmine server.
• Copy the database backup to the new server.

• Stop all servers and start only MySQL.

  $ sudo installdir/ctlscript.sh stop apache
  $ sudo installdir/ctlscript.sh stop mysql
  $ sudo installdir/ctlscript.sh start mysql
  

• Remove the previous database and create the new one. You can configure the database user password with a secure password. Remember to add the -h option to specify the hostname if your database is hosted on a different server.

  $ mysql -u root -p
  Password: ****
  mysql> drop database bitnami_redmine;
  mysql> create database bitnami_redmine;
  mysql> grant all privileges on bitnami_redmine.* to 'bn_redmine'@'localhost' identified by 'DATABASE_PASSWORD';
  

• Restore the new database:

  $ mysql -u root -p bitnami_redmine < backup.sql
  

• Edit the Redmine configuration file to update the database user password (the same that you set previously) at installdir/apps/redmine/htdocs/config/database.yml.

  production:
      adapter: mysql2
      database: bitnami_redmine
      host: localhost
      username: bn_redmine
      password: "DATABASE_PASSWORD"
      encoding: utf8
  

• Migrate the database to the latest version:

  $ cd installdir/apps/redmine/htdocs/
  $ ruby bin/rake db:migrate RAILS_ENV=production
  

• If you have installed plugins in the previous version, copy the directories from the vendor/plugins directory into the new installation area, in the plugins directory. Check that the plugins are compatible with the new version and run the following command:

  $ ruby bin/rake redmine:plugins RAILS_ENV="production"        
  

• Copy the installdir/apps/redmine/htdocs/files directory from the old installation to the new one.

• Clean the cache and the sessions:

  $ ruby bin/rake tmp:cache:clear
  $ ruby bin/rake tmp:sessions:clear
  

• Restart the servers:

  $ sudo installdir/ctlscript.sh restart
  

Troubleshooting upgrades

• If you see the following error, go to your database and remove the specified table and run the migration command again.

  Mysql::Error: Table 'changeset_parents' already exists: CREATE TABLE `changeset_parents` (`changeset_id` int(11) NOT NULL, `parent_id` int(11) NOT NULL) ENGINE=InnoDB
  

  Run these commands:

  $ mysql -u root -p
  mysql> use bitnami_redmine;
  mysql> drop table changeset_parents;
  
  $ cd installdir/apps/redmine/htdocs/
  $ ruby bin/rake db:migrate RAILS_ENV=production
  

• If you upgrade from a 1.x version and you see something similar to this error:

  MysqlStatement::Error Value for field `value` cannot be NULL INSERT INTO custom_value ...
  

  Go to your custom values in the admin panel, edit and save them again to fix the issue.
