It is strongly recommended that you create a full 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
The recommended way to upgrade Redmine is to migrate all the data to a fresh Bitnami installation, which runs the updated version of Redmine.
On the original Redmine server, follow the steps below:
Create a database backup file named bitnami_redmine.sql:
$ mysqldump -u root -p --databases bitnami_redmine --add-drop-database > bitnami_redmine.sql
Compress Redmine application and plugin files from the directory /opt/bitnami/apps/redmine/htdocs/files:
$ tar czf redmine_files.tar.gz -C /opt/bitnami/apps/redmine/htdocs/files . $ tar czf redmine_plugins.tar.gz -C /opt/bitnami/apps/redmine/htdocs/plugins .
Launch a new Redmine server and follow the steps below:
$ sudo /opt/bitnami/ctlscript.sh stop apache
Upload the file redmine_files.tar.gz to the new server.
Restore the database backup:
$ mysql -u root -p < bitnami_redmine.sql
Copy the Redmine application files to /opt/bitnami/apps/redmine/htdocs/files, by copying redmine_files.tar.gz to the new instance and extract its contents:
$ sudo tar xzf redmine_files.tar.gz -C /opt/bitnami/apps/redmine/htdocs/files
Temporarily give full write permissions to the Redmine log file:
$ sudo chmod 666 /opt/bitnami/apps/redmine/htdocs/log/production.log
Migrate the database to the latest version:
$ cd /opt/bitnami/apps/redmine/htdocs/ $ sudo ruby bin/rake db:migrate RAILS_ENV=production
(Optional) If you had installed plugins in your previous installation, follow these steps:
Check that the plugins are compatible with the new version.
Copy the Redmine plugin files to /opt/bitnami/apps/redmine/htdocs/plugins, by copying redmine_plugins.tar.gz to the new instance and extracting it:
$ sudo tar xzf redmine_plugins.tar.gz -C /opt/bitnami/apps/redmine/htdocs/plugins
Install the plugins:
$ ruby bin/rake redmine:plugins RAILS_ENV=production
Clean the cache:
$ ruby bin/rake tmp:clear
Revert the permissions of the Redmine log file:
$ sudo chmod 644 /opt/bitnami/apps/redmine/htdocs/log/production.log
$ sudo /opt/bitnami/ctlscript.sh start apache
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 /opt/bitnami/apps/redmine/htdocs/ $ ruby bin/rake db:migrate RAILS_ENV=production
