- Table of contents
Step 1 - Backup¶
It is recommended that you backup your database and modifications to Foreman files(config/settings.yaml, unattended installations etc). Most upgrades are safe but it never hurts to have a backup just in case.
mysqldump command can be used to backup the contents of your MySQL database to a text file.
SQLite databases are all contained in a single file, so you can back them up by copying the file to another location.
pg_dump command can be used to backup the contents of a PostgreSQL database to a text file.
Step 2 - Perform the upgrade¶
Now it's time to perform the actual upgrade. This process if different depending on how you downloaded Foreman. You only need to perform one of the following options.
Option 1 - Downloaded release (tar.bz2)¶
- Uncompress the new program archive in a new directory.
- Copy your database settings-file
config/database.ymlinto the new
if your database is a simple file (e.g. SQLite), don't forget to make it available in the new directory.
VERY IMPORTANT: do NOT overwrite
config/settings.yml with the old one.
Option 2 - Upgrading from git¶
Please note now that the development branch has moved to Rails 3, you MUST take care to select a branch and make sure you get the correct one.
1. Go to the Foreman root directory and run the following command:
For staying on the stable branch:
git checkout 0.4-stable git pull git submodule init git submodule update
Or if you have to access github through a proxy using the HTTP urls
git checkout 0.4-stable git pull sed -i 's/git:\/\//http:\/\//g' .gitmodules git submodule init git submodule update
For upgrading to the Rails 3 based "develop" branch:
create a new directory checkout a new copy of the code in the new directory using [[Installing_latest_code_]] manually copy relevant config files
For upgrading within the Rails 3 develop branch:
git branch develop git pull
Option 3 - Upgrading from a package (RPM, DEB)¶
Simply update your package via your normally, and you can skip Step 4
Step 4 - Update the database¶
This step is the one that could change the contents of your database. Go to your new Foreman directory (or the git dir), then migrate your database:
rake db:migrate 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)
