READ THIS FIRST!
|
|
|
|
|
----------------
|
|

This document describes upgrading from an older PostfixAdmin version
|
|
|
|
|
(>= v1.5x)
|
|
|
|
|
|
|
|
|
|
It's recommend that you install Postfix Admin in a new folder and not
|
|
|
|
|
on-top of the old install!! (At the very least, make sure you have backups of
|
|
|
|
|
the database and relevant filesystem!)
|
|
|
|
|
|
|
|
|
|
When upgrading Postfix Admin, make sure you backup your database before
|
|
|
|
|
running upgrade.php.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
1. Backup the Database
|
|
|
|
|
----------------------
|
|
|
|
|
When you install from a previous version make sure you backup your database
|
|
|
|
|
first. There are a lot of changes in the database structure since Postfix Admin
|
|
|
|
|
1.5.4.
|
|
|
|
|
|
|
|
|
|
$ mysqldump -a -u root -p > /tmp/postfixadmin-backup.sql
|
|
|
|
|
or
|
|
|
|
|
$ pg_dump -ad -u postfix postfix > /tmp/postfixadmin-backup.sql
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
2. Unarchive new Postfix Admin
|
|
|
|
|
------------------------------
|
|
|
|
|
Make sure that you are in your WWW directory and then unarchive the
|
|
|
|
|
Postfix Admin archive (whatever the filename is):
|
|
|
|
|
|
|
|
|
|
$ tar -zxvf postfixadmin-X.X.tgz
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
3. Change permissions
|
|
|
|
|
----------------------
|
|
|
|
|
Since the database password is stored in the config.inc.php it's a good idea
|
|
|
|
|
to have change the permissions for Postfix Admin.
|
|
|
|
|
|
|
|
|
|
$ cd /usr/local/www/postfixadmin
|
|
|
|
|
$ find -type f -print0 | xargs -0 chmod 640
|
|
|
|
|
$ find -type f -print0 | xargs -0 chown root:www
|
|
|
|
|
|
|
|
|
|
(the last command assumes your Apache is running with group "www")
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
4. Configure
|
|
|
|
|
------------
|
|
|
|
|
Check the config.inc.php file. There you can specify settings that are
|
|
|
|
|
relevant to your setup.
|
|
|
|
|
|
|
|
|
|
Comparing config.inc.php with your previous using "diff" might save you some
|
|
|
|
|
time.
|
|
|
|
|
|
|
|
|
|
You can use a config.local.php file to contain your local settings - these will override any
|
|
|
|
|
defined in config.inc.php
|
|
|
|
|
|
|
|
|
|
5. Run setup.php
|
|
|
|
|
----------------------------------------
|
|
|
|
|
|
|
|
|
|
Access setup.php through a web browser.
|
|
|
|
|
|
|
|
|
|
It will attempt to upgrade your database, and also allow you to create a superadmin user.
|
|
|
|
|
|
|
|
|
|
From version 2.3, you need to specify a setup_password in config.inc.php -
|
|
|
|
|
setup.php should guide you through this process. If you do not have a setup_password, type one
|
|
|
|
|
into the form, and setup.php will echo out the hashed value (which needs to go into config.inc.php).
|
|
|
|
|
The setup_password removes the requirement for you to delete setup.php, and also closes a security hole.
|
|
|
|
|
|
|
|
|
|
Since version 2.2 of Postfixadmin, setup.php can perform the needed database
|
|
|
|
|
updates automatically .
|
|
|
|
|
|
|
|
|
|
If you update from 2.1 or older, also create a superadmin account using setup.php.
|
|
|
|
|
|
|
|
|
|
Note that admin/ has been merged into the main directory. Login with the
|
|
|
|
|
superadmin account to setup domains and domain admins.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
6. Done
|
|
|
|
|
-------
|
|
|
|
|
This is all that is needed. Fire up your browser and go to the site that you
|
|
|
|
|
specified to host Postfix Admin.
