<P>phpGroupWare is a web based groupware application that includes integrated features such as

|
|
email, calendar, todo list, address book, file manager, headline news, and a trouble ticket system.
|

|
|
|
<P>It should run on all systems where PHP is available and currently supports MySQL and PostgreSQL.

<P>
|
|
|

|
<P>You should use it if:
|
|
|
|
|
<P>You would like a powerful groupware system that can be access from anywhere on the Internet.
|
|
|
|

For companies with a distributed user base, it's an ideal solution. Oh, and did I mention that its FREE?

|
|
|
|
<H2>2.1 Requirements</H2>
|
|
|
|
|
|
|
|
|
|
<P>You will need PHP compiled and installed on your system. You will also need MySQL or PostgreSQL setup.
|
|
|
|
|
If you are planning on using the email system, you will need to have an IMAP server installed and IMAP support compiled into PHP.
|
2000-09-27 17:10:44 +02:00
|
|
|
You can have it installed as an Apache module or command line version, the Apache module is preferred.
|
2000-08-18 05:24:22 +02:00
|
|
|
We will assume that you are running on a Linux or other Unix system for these steps.
|
|
|
|
|
Windows is supported, but there is no documentation for it currently.

<H2>2.3 Obtaining phpGroupWare</H2>
|
|
|
|
|
|
|
|
|
|
<P>While we are still in the Beta phase of phpGroupWare, you may
|
|
|
|
|
want to track the CVS copy as closely as possible. The released
|
|
|
|
|
versions are more stable, but often contain bugs that have been fixed
|
|
|
|
|
in the CVS version.
|
|
|
|
|
<H3>Released Versions</H3>
|
|
|
|
|
|
|
|
|
|
<P>The downloads section on the
|
|
|
|
|
<A HREF="http://www.phpgroupware.org/">http://www.phpgroupware.org/</A> site
|
|
|
|
|
contains links to the most recent releases, and several mirror sites
|
|
|
|
|
for the releases.
|
|
|
|
|
<H3>Developer's version from CVS</H3>
|
|
|
|
|
|
|
|
|
|
<P>If you have never used CVS, you may want to read through the doucmentation
|
|
|
|
|
found at
|
|
|
|
|
<A HREF="http://www.cvshome.org/">http://www.cvshome.org/</A>.
|
|
|
|
|
The CVS pages for the core and apps projects can be found at
|
|
|
|
|
<A HREF="http://sourceforge.net/cvs/?group_id=7305">phpGroupWare Core CVS</A>, and
|
|
|
|
|
<A HREF="http://sourceforge.net/cvs/?group_id=9787">phpGroupWare Apps CVS</A>.
|
|
|
|
|
Follow the directions for <B>Anonymous CVS access</B> and you should
|
|
|
|
|
have the most recent development copy of phpGroupWare in no time.

|
2000-08-18 05:24:22 +02:00
|
|
|
|
|
|
|
|
<P>After you have met the system requirements, unpack the tarball in the html
|
|
|
|
|
directory of your webserver. (eg, /home/httpd/html)
|
|
|
|
|
<P>The first step is to setup the database and create the tables needed. In the
|
|
|
|
|
doc directory there is a file called create_tables.(name of your database)

|
|
|
|
<H3>Installation with MySQL</H3>

|
2000-09-07 23:10:17 +02:00

<H2>2.5 Configure phpGroupWare</H2>

2000-08-18 05:24:22 +02:00
|
|
|
|
2000-09-27 17:10:44 +02:00
|
|
|
<P>Copy the <CODE>header.inc.php.sample</CODE> file to
|
|
|
|
|
<CODE>header.inc.php</CODE> and edit the file, following the
|
|
|
|
|
directions in the comments.
|
2000-08-18 05:24:22 +02:00
|
|
|
<P>Change to the inc directory. <BR>
|
2000-09-27 17:10:44 +02:00
|
|
|
Copy <CODE>globalconfig.inc.php.sample</CODE> to <CODE>globalconfig.inc.php</CODE>
|
|
|
|
|
and edit it to reflect your system settings, again following the
|
|
|
|
|
comments in the file.
|
2000-08-18 05:24:22 +02:00
|
|
|
<P>If you are using the email system you will need to create a temporary directory
|
|
|
|
|
where file uploads will be stored. For security reasons, you should <CODE>chown
|
|
|
|
|
nobody.nobody</CODE> and <CODE>chmod 700</CODE> to that directory. Depending on your system configuration.
|
|
|
|
|
Default installs of Apache normally run as the user nobody. You may need your system
|
|
|
|
|
administrator to do this for you if you do not have root access.
|
|
|
|
|
<P>If you do not have access to root, create this file and run it.

If you have access to cron, you may want to setup the files in the cron

<LI>Users always forget to logout. This way the session doesn't sit around forever, creating a possible security risk. </LI>

<LI>The email system requires plain text passwords which are stored in the sessions table.</LI>

2000-09-07 23:10:17 +02:00

<P>This file is not required, you can simply disable cron_apps in the admin -> applications section
|
2000-09-27 17:10:44 +02:00
|
|
|
to clean out the sessions table during login and logout.
|
2000-08-18 05:24:22 +02:00
|
|
|
<P>stale_uploads.pl - This will delete file attachments for messages that where not
|
2000-09-27 17:10:44 +02:00
|
|
|
completed. If a users browser crashes, Internet connection dies, etc, their
|
2000-08-18 05:24:22 +02:00
|
|
|
files will sit there forever unless deleted. You could add a few lines to
|
|
|
|
|
logout.php that will look in the temp directory for any stale uploads and delete
|
|
|
|
|
them. But, once again, it becomes a performance issue.

2000-08-18 05:24:22 +02:00

<P>If your config is setup properly you can now login. Point your browser to the

installed location and login with the username <CODE>demo</CODE> and the password is <CODE>1234</CODE><BR>
|
2000-09-27 17:10:44 +02:00

At this point it would be a good idea to create a new user with administrative privileges and

delete the old one.

<P>Once you have the core phpGroupWare install up and running,

|

you may want to download and install additional applications.
|
|
|
|
|
<P>You should consult any <CODE>README</CODE> or <CODE>INSTALL</CODE>
|
|
|
|
|
files that come with the new application first, as most require you
|
|
|
|
|
to create additional tables in the database, and add additional
|
|
|
|
|
translation data to the lang table (typically a file called <CODE>lang.sql</CODE>)
|
|
|
|
|
<P>You install the new application within the phpGroupWare install tree by
|
|
|
|
|
copying the application directory into the phpGroupWare install location,
|
|
|
|
|
and enabling the application through the Administration page.
|
|

<H2>5.1 I get "Unable to open mailbox" when using the email application</H2>
|
|
|
|
|
|
|
|
|
|
<P>At the time of this writing (2000-09-27) you must use the same
|
|
|
|
|
username and password in phpGroupWare that you use to log into
|
|
|
|
|
your mail server. If you change your password and it still isn't working,

try logging out of phpGroupWare (the rightmost icon in the navigation bar)
|
|
|
|
|
and then log back in.
|

<P>An preference page to edit the email settings is being developed, and should

appear shortly after the first beta release.

<H2>5.2 It seems to hang when I try to read my mail</H2>

<P>This is often a problem if you are using POP3 instead of IMAP, and you have
|
|
|
|
|
more than a few hundred messages in your mailbox.
|
|
|
|
|
<P>By default, php is set up to time-out a request that takes over 30 seconds
|
|
|
|
|
to complete. phpGroupWare must do a lot of work the first time your POP3 mailbox
|
|
|
|
|
is opened, and every time you get new mail, which may take more than the 30
|
|
|
|
|
second timeout.
|

<P>You can either clean up your mailbox with another mail program, or
