You have a package (deb or rpm) installed redmine version and you want to switch to the source maintained redmine?
This article describes how to transfer your Redmine instance based on PostgreSQL to Ubuntu 20.04 instance.
You ask why we decided to switch to source based if the Ubuntu / Debian maintained redmine is available? Why to have the drawback to manage the updates yourself?
The answer is pretty simple. After using redmine since years with Ubuntu maintained installation, we have faced that the maintainers of the debian package are – sadly have to say – do a bad job. E.g. with Ubuntu 20.04 they have managed to use a ruby version which was not released by redmine team at all. So it created a mess with the debian package installation if you have tons of issues already. If you consider the fact that this issue is still not fixed, even if it was reported in the first weeks of the release of Ubuntu 20.04 and we have now march 2022!
You can imagine a some rate of frustration and also the drawback to wait for 2 years for a newer redmine version.
Create backups from old server
We may have these 4 data areas to backup:
- redmine attached files and docs
- redmine plugins
- redmine themes
First we need to dump the database from old server
sudo su - postgres -c 'psql -c "select datname from pg_database;"' | grep redmine
This will report you the database name. Iif you do not get an result run
sudo su - postgres -c 'psql -c "select * from pg_database;"'
For paranoid checks, let us verify the database name from the config too, by checking the database.yml
Under Ubuntu or Debian based installations the redmine configuration are located underneath /etc/redmine
cat /etc/redmine/default/database.yml | grep database
In my case the default database name is: redmine_default
Now let us dump the database into a file
sudo su - postgres -c 'pg_dump -C redmine_default | gzip > /tmp/redminedb.sql.gz'
copy to new server
scp /tmp/redminedb.sql.gz user@newserverhostname:/tmp/
Backup attachment files and docs
First identify where the files are located with
grep attachments_storage_path /etc/redmine/default/configuration.yml | grep -v "^\s*#"
In my case it was reporting:
Now let us create the backup file
cd /var/lib/redmine/default/files tar zcf /tmp/redmine-attachments.tar.gz .
copy to new server
scp /tmp/redmine-attachments.tar.gz user@newserverhostname:/tmp/
Backup installed plugins
You will need your plugins again. Best way is to backup and restore them. Backup the files
cd /usr/share/redmine/plugins/ tar zcf /tmp/redmine-plugins.tar.gz .
copy to new server
scp /tmp/redmine-plugins.tar.gz user@newserverhostname:/tmp/
Backup installed themes
You will need your themes again. Best way is to backup and restore them. Backup the files
cd /usr/share/redmine/public/themes tar zcf /tmp/redmine-themes.tar.gz .
copy to new server
scp /tmp/redmine-plugins.tar.bz2 user@newserverhostname:/tmp/
Prepare your new Ubuntu 20.04 target server
login to your new server
You will need this packages to have apache2 and ruby passanger installed
sudo apt update sudo apt dist-upgrade -y sudo apt autoremove -y sudo apt install -y apg build-essential libmysqlclient-dev libmysqlclient-dev imagemagick libmagickwand-dev libmagickcore-dev sudo apt install -y dirmngr gnupg apt-transport-https ca-certificates apache2 apache2-dev libapache2-mod-passenger sudo apt install -y ruby ruby-dev bundler sudo apt install -y subversion git sudo apt install -y postgresql postgresql-client postgresql-contrib postgresql-doc
Prepare DB – PostgreSQL
Create the new database with the required permissions
DBPWD=`apg -M sNCL -n 1 -m 16` && echo -e "#"'!'"/bin/bash\n\nDBPWD=$DBPWD\nexport DBPWD\necho DBPWD=$DBPWD" > /tmp/db-pwd.sh source /tmp/db-pwd.sh echo "using password $DBWPD"
Now take your generated password or your own password and enter it into the following command
sudo su - postgres -c "source /tmp/db-pwd.sh && psql -c \"CREATE ROLE redmine LOGIN ENCRYPTED PASSWORD 'yourPassword' NOINHERIT VALID UNTIL 'infinity';\"" sudo su - postgres -c "zcat /tmp/redminedb.sql.gz | psql --set ON_ERROR_STOP=on"
now let us import the data into our new database
sudo su - postgres -c "psql -c \"CREATE DATABASE redmine WITH ENCODING='UTF8' OWNER=redmine;\""
Fetch the redmine sources. Now you have to decide to which version to work with. In the case of this tutorial the migration happend specifically from Ubuntu 20.04 with redmine debian package, which is 4.0.6 version. So the migration will happen first to the same source version or course.
sudo su - cd /opt/ git clone https://github.com/redmine/redmine.git cd redmine git checkout 4.0.6
configure the database
mkdir -p /etc/redmine/default cp /opt/redmine/config/database.yml.example /etc/redmine/default/database.yml ln -s /etc/redmine/default/database.yml /opt/redmine/config/database.yml cp /opt/redmine/config/configuration.yml.example /etc/redmine/default/configuration.yml ln -s /etc/redmine/default/configuration.yml /opt/redmine/config/configuration.yml
Now configure the database config file with the relevant settings with
change your configuration to this
Mail / SMTP configuration
Now configure the redmine config file with the relevant settings with
Attachment files and folders configuration
Now configure the attachment folder
mkdir -p /var/lib/redmine/default/files
tar zxf /tmp/redmine-attachments.tar.gz
Prepare for apache setup
sudo chown -R www-data:www-data /opt/redmine/ sudo chmod -R 755 /opt/redmine/ sudo ln -s /usr/share/redmine/public /var/www/redmine
gem install bundler bundle install --without development test
