Installation Joomla Step 07
Main Configuration
The Main Configuration screen allows the setting of three critical elements for the installation of Joomla! to your Web server.
The Main Configuration screen of the Joomla! installation process
There are three sections to the Main Configuration screen; the first of which is the Site Name. Whilst this may appear obvious it does bear pointing out that this is also the name that will be used when site e-mails are issued, or when error or access warning messages are issued from the Front-end of the Web site. Unlike in earlier releases of Joomla!, and its predecessor, the Site Name will not appear in the User's browser title bar.
This entry can be edited at a later time in the Global Configuration->Site page of the Control Panel.
The second section relates to key information concerning the primary Super Administrator, you!
Enter your e-mail address, or the one that you want all site warnings, messages, and e-mails to be sent from and that incoming contact methods will be directed to. It will appear as the From address on all Site outgoing e-mail messages. There are also two text fields into which you should enter and confirm the password that you will (as the primary Super Administrator) use to login to the Web site, in combination with the default username for the primary Super Administrator, which by default is admin.
Caution: It is worth pointing out that at least for public sites the MySQL,FTP, and Login usernames and passwords should not be the same. To do so would add unnecessary security risks.
If you are migrating data from an existing Joomla! 1.0 installation, or uploading a full SQL back-up from an existing Joomla! 1.5 installation, you do not need to complete these first two sections as the information will be automatically transferred within the migration script or back-up file.
An additional security suggestion that you might consider is to change the User admin to something less obvious once the installation is completed. This can be done (along with any subsequent changes you wish to make to the password) in the Control Panel->Site menus->User Manager screen of the Administrator Back-end.
The third and final section relates to the data that you may, or indeed may not, want to include in the installation process.
Essentially you have three choices:
- enter the default sample data that Joomla! provides within the core distribution,
- upload your own data. This may be from:
- a migration of the data from an earlier version of Joomla! using the migration tools available
- an existing Joomla! 1.5 data from perhaps a back-up that has been created from another Web site although there is no specific procedure in this section to undertake this.
- a migration of the data from an earlier version of Joomla! using the migration tools available
- do none of the foregoing and start a completely fresh and empty installation of Joomla!
- Looking at these options one at a time:
Installing the Default Sample Data
The sample default data is a collection of Sections, Categories, Articles, Web Links, News Feeds, and various other examples of content that have been written simply to demonstrate some of the functionality of Joomla! (much of the content is also quite informative and useful). The data is contained in an SQL file within the core installation.
By default the Install Default Sample Data radio button is selected, but in order to complete the installation of the Sample Data you must also click the adjacent Install Sample Data button. Provided all goes well you will notice that this button transforms into a confirmatory message box stating that the Sample Data Installed Successfully; you are then ready to complete this section by clicking Next.
It is not possible to simply do an SQL back-up of a 1.0.x version Web site and upload this to a 1.5 version installation as a result of the significant changes that have taken place with regard to the framework of Joomla!.
Installing a Compatible SQL Script File
There may be situations where for example you have your own localised – in language terms – version of the Sample Data, or a back-up of data from an existing Joomla! 1.5 Web site that you wish to restore/install into the new Web site you are creating. You should complete the Old Table Prefix, and Migration Script items below.
Installing a Migration SQL Script File from an earlier Joomla! version 1.0.x installation
There is a separate and detailed guide on migrating content from earlier Joomla! installations available from the Joomla! Help Site regarding the Migrator Component.
If you are migrating or restoring data select the Load Migration Script radio button. You will notice that this then enables the additional fields for Old Table Prefix, Old Site Encoding, and Migration Script.
- Old Table Prefix:
- This is the prefix used in the database from which the data is being transferred. For example, it may be mos_ from a default Joomla! 1.0 installation or, if uploading from a core SQL file #__.
- Old Site Encoding:
- Refers to the Language Encoding used by the donor MySQL database also known as the Collation. Joomla! 1.5 must be encoded with the UTF-8 language. The Old Site Encoding details can be obtained by referring (in PHPMyAdmin) to the Databases tab of the main page.
- Migration Script:
- Browse to the Migration Script SQL data file you want to upload from a Joomla! 1.0.x installation that has been created using the Migrator Component.
The Migrator Component clearly cannot compensate (add) data to any new fields that have been added by the Joomla! 1.5 development (it's good but not magical) therefore it is recommended that you check all migrated data and complete any missing fields that require such action. The most prevalent of these will be the Alias field of Sections, Categories, and Articles.
- I have already uploaded...:
- Select this check box if you find that the SQL file is too big to handle (memory and time limit errors) and upload the file in the joomla_root/installation/sql/migration/ called migrate.sql (no compression allowed) using an FTP client program
- This script is a Joomla! 1.0 migration script:
- Check this box if (and only if) you are migrating data from an earlier Joomla! 1.0 Web installation, having used the com_migrator Component. This will enable the built in automatic process to complete the transformation of the data to a compatible format with the Joomla! 1.5 framework.
Once you have completed the details on this page select Next to proceed to the final step.
