17cec454 141. CONFIGURE YOUR WEBSERVER TO WORK WITH PHP4
15---------------------------------------------
f8f9bed9 16
17cec454 17 If your webserver does not already have PHP4 you must configure it
18 to work with PHP4. SquirrelMail uses the standard suffix .php for
19 all PHP4 files. This is a quick and dirty guide to installing PHP4
20 to run as CGI under Apache. How you end up doing this is up to you
21 (your mileage may vary).
9b57e848 22
eb0a8c50 23 NOTE: The new plugin architecture required the use of some functions
24 which are not in all versions of PHP4. You will need at least
25 PHP4 beta2. If you need to upgrade please go ahead and install the
26 latest release version of PHP4.
27
17cec454 28a. Obtaining and compiling PHP4
f8f9bed9 29
17cec454 30 Point your favorite webserver at http://www.php.net/version4/ and
31 download the source. Untar (tar xvfz filename-you-downloaded.tgz)
32 the source, cd into the directory and run configure. To make PHP4
33 work with SquirrelMail a commandline like this should do:
f8f9bed9 34
17cec454 35 ./configure --enable-track-vars --enable-force-cgi-redirect --with-gettext
f8ba9180 36
17cec454 37 If you have a database like MySQL you might want to add something
38 like --with-mysql to get database functionality.
39
45c0a3a3 40 If you're going to use LDAP in the addressbook, you must compile PHP4
41 with --with-ldap (see the PHP4 docs for more information).
42
17cec454 43 Run make to build the binary file. This will generate a binary file
44 called "php". Move this file into a CGI-directory.
45
46 You might also want to read the INSTALL file in the PHP-distribution
47 :-)

2a32fc83 49b. Changing php.ini
50
51 PHP defaults to look for php.ini (PHP's configuration file) in
52 /usr/local/lib. However, for security reasons, it is suggested
53 that the location of this file is changed to someplace else. This
54 can be done at configure time with the configuration directive
55 --with-config-file-path=PATH.
56
a167feaf 57 Edit the php.ini file and make sure session.use_cookies is 1. Also
58 be sure to change the session.save_path to someplace that can only
59 be read and written to by the webserver. session.save_path is the
2a32fc83 60 location that PHP's session data will be written to.
61
a167feaf 62 SECURITY WARNING - If a user has access to write PHP scripts on your
63 system and knows the location where PHP stores session data, he
64 could get a listing of the sessions being used and then read a given
65 session's data with his own PHP script. Caution should be used when
66 setting up permissions and locations of php.ini and the session data.
2a32fc83 67
68c. Setting up .php files to use PHP4
17cec454 69
70 You need to create a .htaccess file in you SquirrelMail directory
71 that looks something like this:
72
73 AddType application/php4script .php
74 Action application/php4script /cgi-bin/php
75
76 You could also add these lines to your Apache configuration file.
77
2a32fc83 78d. Running into trouble
17cec454 79
80 Setting up Apache with PHP4 can be a non-trivial task. Read the PHP4
81 and Apache documentation carefully if you run into trouble. If you
82 have an experienced system administrator around ask her/him to help
83 you.

852. SETTING UP IMAP
86------------------
87
88 This is not covered here :-/

903. OBTAINING AND INSTALLING SQUIRRELMAIL
91----------------------------------------
92
93 SquirrelMail is still under development. Therefore you should always
94 get the newest version around. Look at
429f8906 95 http://www.squirrelmail.org/index.php3?page=5 to see what it
17cec454 96 is. If you want to be bleeding edge you might want to consider using
97 the latest CVS version (with the latest and most fashionable of
98 bugs).
99
100a. Download SquirrelMail
101
102 Get SquirrelMail from the address above if you do not have it or are
103 uncertain if you have the newest version. Untar (again tar xvfz
104 filename.tgz) SquirrelMail in a directory that is readable for your
105 webserver.
106
107b. Setting up directories
108
109 SquirrelMail uses two directories to store user configuration and
110 attachments that are about to be sent. You might want to have these
111 directories outside of your web tree.
112
113 The data directory is used for storing user preferences, like
114 signature, name and theme. When unpacking the sources this directory
b731cd83 115 is created as data/ in your SquirrelMail directory. This directory
17cec454 116 must be writable by the webserver. If your webserver is running as
b731cd83 117 the user "nobody" you can fix this by running:
65b14f90 118
390372b4 119 $ chown -R nobody data
120 $ chgrp -R nobody data
17cec454 121
122 There also needs to be a directory where attachments are stored
123 before they are sent. Since personal mail is stored in this
124 directory you might want to be a bit careful about how you set it
125 up. It should be owned by another user than the webserver is running
126 as (root might be a good choice) and the webserver should have write
127 and execute permissions on the directory, but should not have read
128 permissions. You could do this by running these commands (still
129 granted that the webserver is running as nobody/nobody)
130
390372b4 131 $ cd /var/some/place
132 $ mkdir SomeDirectory
133 $ chgrp -R nobody SomeDirectory
134 $ chmod 730 SomeDirectory
17cec454 135
136 If you trust all the users on you system not to read mail they are
137 not supposed to read change the last line to chmod 777 SomeDirectory
390372b4 138 or simply use /tmp as you attachments directory.
139
140 If a user is aborting a mail but has uploaded som attachments to it
141 the files will be lying around in this directory forever if you do not
142 remove them. To fix this, it is recommended to create a cron job that
143 deletes everything in the attachment directory. Something similar
144 to the folling will be good enough:
145
146 $ cd /var/attach/directory
147 $ rm -f *
17cec454 148
149c. Setting up SquirrelMail
150
be8e07f8 151 There are two ways to configure Squirrelmail. In the config/ directory,
152 there is a perl script called conf.pl that will aid you in the
390372b4 153 configuration process. This is the recommended way of handling
be8e07f8 154 the config.
155
390372b4 156 You can also copy the config/config_default.php file to config/config.php
be8e07f8 157 and edit that manually.
65b14f90 158
17cec454 1594. RUNNING SQUIRRELMAIL
160-----------------------
65b14f90 161
429f8906 162 Point your browser at the URL at which SquirrelMail is installed. A
163 possible example of this is:
164 http://www.yourdomain.com/squirrelmail
165
166 It should be pretty stright forward to use. Some more documentation
167 might show up one day or another.
