Install eaccelerator on FC4 with php 5.0.4

Eaccelerator is a PHP accelerator/encoder/caching utility that is based off of the old mmcache (which is no longer being maintained). What Eaccelerator does is it caches your PHP scripts so that the database is no longer being queried everytime someone needs a script. This is
particularly useful for large forums, but pretty much anyone can benefit from it. Since these scripts are cached, you’ll notice a decrease in memory use and server load.

Installation procedure.
Lets get the source file first.
wget http://heanet.dl.sourceforge.net/sourceforge/eaccelerator/eaccelerator-0.9.4-rc1.tar.bz2

bzip2 -d eaccelerator-0.9.4-rc1.tar.bz2
tar xvf eaccelerator-0.9.4-rc1.tar

Note:
1) you need to find where PHP is installed. For most, it’s usually either “/usr/bin” or “/usr/local”, but it may be something else. you can find using which php command.
2) if you are getting phpize: command not found , Then you need to install php-devel.

yum install php-devel

cd eaccelerator-0.9.4-rc1/

phpize
./configure –enable-eaccelerator=shared –with-php-config=/usr/bin/php-config
make
make install

Take note of where the shared lib was installed (last line of output of the the above command

cp eaccelerator.ini /etc/php.d

Edit the above (copied) file, locate this line:
zend_extension_ts=”/usr/lib/php4/eaccelerator.so”

and replace it with ( whatever path you have noted )

zend_extension=”/usr/lib/php/modules/eaccelerator.so”

Now all that’s left is to create a tmp dir for eaccelerator’s cache (/tmp/eaccelerator is the default, but you can change it in the above file), and restart apache.

mkdir /tmp/eaccelerator
chown apache /tmp/eaccelerator
chgrp apache /tmp/eaccelerator
chmod 644 /tmp/eaccelerator
/sbin/service httpd restart

Test by knocking up a phpinfo.php page or give php -v command via shell you should note.

Installing SquirrelMail on Unix and Linux systems

This articler covers installation of SquirrelMail on generic Unix or Linux system. It does not cover installation of operating system or tools required to install web server or PHP. Any version numbers used in examples are specific to the time when this documentation is written. If current version numbers differ, make sure that you are not using old, obsolete or vulnerable software. Guide uses UW IMAP server as example. This IMAP server can be used in generic email setup when incoming mail is stored in /var/spool/mail directory. If you are planning to use webmail with big number of users or with bigger mailboxes, consider using different IMAP server and redesign entire email system.
Download required software

You will need:

* Apache – http://httpd.apache.org/download.cgi
* PHP – http://php.net/downloads.php
* UW IMAP – http://www.washington.edu/imap/
* SquirrelMail – http://squirrelmail.org/download.php

# install -d /usr/local/src/downloads
# cd /usr/local/src/downloads
# wget http://some-apache-mirror-server/apache/httpd/httpd-2.0.54.tar.gz
# wget http://some-php-mirror-server/get/php-4.3.11.tar.bz2/from/this/mirror
# wget ftp://ftp.cac.washington.edu/mail/imap.tar.Z
# wget http://some-sourceforge-mirror/some-path/squirrelmail-1.4.5.tar.bz2

Unpack and install apache

# cd /usr/local/src
# tar -xzvf /usr/local/src/downloads/httpd-2.0.54.tar.gz
# cd httpd-2.0.54
# ./configure –prefix=/usr/local/apache –enable-module=so
# make
# make install

Unpack and install php

# cd /usr/local/src
# tar –bzip2 -xvf /usr/local/src/downloads/php-4.3.11.tar.bz2
# cd php-4.3.11
# ./configure –prefix=/usr/local/php \
> –with-apxs2=/usr/local/apache/bin/apxs
# make
# make install

If you configure PHP compilation with –disable-all option, you must add –enable-session and –with-pcre-regex options.
Add PHP support to apache

<IfModule mod_php4.c>
AddType application/x-httpd-php .php
</IfModule>

Restart apache and check if php is working

/usr/local/apache/bin/apachectl graceful

<?php phpinfo(); ?>

Unpack and install imap server

Unpack UW IMAP archive.

# cd /usr/local/src
# tar -xzvf /usr/local/src/downloads/imap.tar.Z

Compile UW IMAP

cd /usr/local/src/imap-<someversion>
make port-name EXTRADRIVERS=” SSLTYPE=unix

Replace port-name with name that matches your system. Check Makefile for possible values. If you haven’t installed OpenSSL libraries and headers, use SSLTYPE=none instead of SSLTYPE=unix.

Install IMAP server binary

strip imapd/imapd
install -d /usr/local/libexec/
cp imapd/imapd /usr/local/libexec/

Enable IMAP server in inetd.conf

imap2 stream tcp nowait root /usr/sbin/tcpd /usr/local/libexec/imapd

Restart inetd

Prepare SquirrelMail directories

# mkdir /usr/local/squirrelmail
# cd /usr/local/squirrelmail
# mkdir data temp
# chgrp nogroup data temp
# chmod 0730 data temp

Unpack SquirrelMail

# cd /usr/local/squirrelmail
# tar –bzip2 -xvf /usr/local/src/downloads/squirrelmail-1.4.5.tar.bz2
# mv squirrelmail-1.4.5 www

Configure SquirrelMail

Start SquirrelMail configuration utility. Configure SquirrelMail with UW preset. Set data and attachment directories.
Configure access to SquirrelMail in Apache

Modify httpd.conf

Alias /squirrelmail /usr/local/squirrelmail/www
<Directory /usr/local/squirrelmail/www>
Options Indexes
AllowOverride none
DirectoryIndex index.php
Order allow,deny
allow from all
</Directory>

Log into SquirrelMail

After you add alias to SquirrelMail in apache configuration and restart apache, you should be able to access SquirrelMail by going to http://your-server/squirrelmail.

Apache mod_rewrite

This module uses a rule-based rewriting engine (based on a regular-expression parser) to rewrite requested URLs on the fly. It supports an unlimited number of rules and an unlimited number of attached rule conditions for each rule to provide a really flexible and powerful URL manipulation mechanism. The URL manipulations can depend on various tests, for instance server variables, environment variables, HTTP headers, time stamps and even external database lookups in various formats can be used to achieve a really granular URL matching….

Apache cannot be started with the error “(98)Address already in use: make_sock: could not bind to address [::]:443 no listening sockets available, shutting down

First of all make sure that “Listen” directive is specified only once in Apache configuration for one port. Chcek the httpd.conf and conf.d/* files in order to find it (on some OSes, like SUsE also /etc/apache2/* should be chacked).
