env-variables: make it safer if there's a syntax problem inside .ini file. It's better to not crash, since it means server wont start. Let users fix problems instead of breaking the startup because of that.

Moving From Windows to Linux

If you are moving from a Windows server to a Linux server, especially from running an older version of |RCE| pre 2.x, use the following information to successfully migrate your instances and database.

Overview

  • Install |RCC| on your Linux server, use the :ref:`RhodeCode Control Docs <control:rcc>` to guide you through this.
  • Copy your |repos| directory to the Linux server.
  • Copy your original :file:`rhodecode.ini` file to the Linux server, named :file:`production.ini` in older versions, and make a minor edit to point to the copied database.
  • Copy your original instance database and update Windows paths to Linux paths pointing to your |repos| directory.
  • Use |RCC| to import and upgrade your |RCE| instance, using the copied and edited file and database.

Pre-requisites

  • For MySQL, do not use localhost in the database connection string of the :file:`rhodecode.ini` file.
  • InnoDB must be the database tables engine.
  • Contact |RC| for a new licence Key/Token pair. If you don't, a trial licence will be applied so you are not locked out of the upgraded instance.

You can find the specific instructions to carry out these pre-requisite steps in the :ref:`RhodeCode Control upgrade <control:rce-upgrade-2x>` docs.

Configuration File Update

Configure the copied :file:`rhodecode.ini` file to connect to your copied database. Use the following steps:

  1. Open the copied :file:`rhodecode.ini` file.
  2. When you open the file, find the database configuration section, and use the below example to change the connection details:
#########################################################
### DB CONFIGS - EACH DB WILL HAVE IT'S OWN CONFIG    ###
#########################################################

# Point to copied DB
sqlalchemy.db1.url = postgresql://postgres:qwe@localhost/rhodecode.db.copy
sqlalchemy.db1.url = mysql://root:qweqwe@127.0.0.1/rhodecode.db.copy

Database Update

Update the Windows paths in the rhodecode.rhodecode_ui database tables. To do this log into the database and reset the file paths to Unix format. One login option is to use iShell, see usage examples in the :ref:`rhodecode-reset-ref` section.

In [28]: from rhodecode.model.settings import SettingsModel
In [29]: paths = SettingsModel().get_ui_by_section('paths')
In [30]: paths[0].value = '/home/user/repos'
In [32]: Session().add(paths[0])
In [33]: Session().commit()

Import and Upgrade

Once you have made your changes, use |RCC| to import and upgrade your |RCE| instance to the latest version.

# Import original instance as explained above
$ rccontrol import Enterprise path/to/rhodecode.ini

# Install a VCS Server as explained above
$ rccontrol install VCSServer

# Check the status of them
$ rccontrol status

Post Migration Tasks

  • From the |RCE| :menuselection:`Admin --> Settings --> VCS` page, check that the :guilabel:`Repositories Location` is correctly pointing to your |repos|.
  • Remap and rescan |repos| so that the new instance picks them up, see :ref:`remap-rescan`.
