Compiling key non-FreeNAC components from sources

Introduction

This document explains how to compile key components from source, if needed. It is recommended to use the packages that are included with your distribution if possible, since automated updates will be easier.

It was last updated in Mar'07, and refers to versions available on that date.

Download

You'll need to download the packages, always use the latest releases, the following are example URLs.

http://mirror.switch.ch/ftp/mirror/apache/dist/httpd/httpd-2.2.2.tar.gz
http://mirror.switch.ch/ftp/mirror/mysql/Downloads/MySQL-5.0/mysql-5.0.2...
ftp://fr.rpmfind.net/pub/libxml/libxml2-2.6.23.tar.gz
http://www.ibiblio.org/pub/Linux/ALPHA/freetds/stable/release_candidates...
http://ch2.php.net/get/php-5.2.0.tar.bz2/from/this/mirror

Apache

cd /opt/install
tar xvzf httpd-2.2.2.tar.gz
cd httpd-2.2.2
./configure --prefix=/usr/local/apache2 --enable-so
make install
ln -s /usr/local/apache2 /usr/local/apache
ln -s /usr/local/apache2/bin/apachectl /etc/init.d/apache2
ln -s /usr/local/apache2/bin/apachectl /sbin/rcapache2

# Actually start apache if you intend using the web interfaces, see below:
chkconfig apache2 on
/etc/init.d/apache2 start

MYSQL 5

Prerequisites: ncurses-devel gcc-c++

cd /opt/install
tar xvzf mysql-5.0.27.tar.gz
cd mysql-5.0.27
./configure --prefix=/usr/local/mysql-5.0.27 --localstatedir=/mysqldata --with-unix-socket-path=/var/lib/mysql/mysql.sock
make install

cd /usr/local
mv mysql mysql.$$ [in case you have a link already]
ln -s mysql-5.0.27 mysql
ln -s /usr/local/mysql/bin/mysqld_safe /usr/local/mysql/bin/mysql

Create a mysql user:
groupadd mysql
useradd -g mysql mysql

Create an empty database:
cd /usr/local/mysql
bin/mysql_install_db --user=mysql
mv data /var/lib/mysql

ln -s /var/lib/mysql data
ln -s /var/lib/mysql /mysqldata
ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

Set permissions:
chown -R mysql:mysql /mysqldata /var/lib/mysql

libxml

cd /opt/install
tar xvzf libxml2-2.6.24.tar.gz
cd libxml2-2.6.24/
./configure --prefix=/opt/libxml2 && make install

FreeTDS

If you need to access MS-SQL or Sybase Enterprise databases.

cd /opt/install
wget http://www.ibiblio.org/pub/Linux/ALPHA/freetds/stable/release_candidates...
tar xvzf freetds-0.64RC2.tar.gz
cd freetds-0.64RC2
./configure --prefix=/opt/freetds --enable-msdblib
make install
vi /opt/freetds/etc/freetds.conf and add a definition to a DB to test:
[sms] <-- alias name
host = MyServer.mydomain.com <-- sever name/IP
port = 1433
tds version = 4.2
dump file = /var/log/freetds.log
dump file append = yes
#debug level = 10
debug level = 3

Try connectivity:
/opt/freetds/bin/tsql -S [alias] -U [user] -P [password]

PHP5

Install first the prerequisites packages, PHP is built with many options enabled: gd-devel freetype2-devel zlib-devel libpng-devel libjpeg-devel
net-snmp net-snmp-devel tcpd-devel rpm-devel
openssl openssl-devel openldap2-devel graphviz

cd /opt/install;
tar xBf php-5.2.0.tar.bz2
cd php-5.2.0

## If you need MS-SQL (its best to assume you do - FreeTDS was compiled above)
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr/local/mysql --with-mysql-sock=/var/lib/mysql/mysql.sock --prefix=/opt/php-5.2.0 --with-xml --with-libxml-dir=/opt/libxml2 --enable-pcntl --enable-force-cgi-redirect --with-mssql=/opt/freetds --with-gd --with-zlib-dir --with-ttf --with-freetype-dir --with-snmp=/usr --enable-ucd-snmp-hack --with-ldap

make install

Disable any current php binaries, and enable the new ones:

mv /usr/bin/php /usr/bin/php.$$
mv /opt/php5 /opt/php5.$$
ln -s /opt/php-5.2.0 /opt/php5
ln -s /opt/php5/bin/php /usr/bin/php

Test PHP:
php -v

Note:

• On Suse Linux, PHP may complain about MySQL libraries, it may be best to compile MySQL from source (see above), rather than using binary packages.
• If MS-SQL support (via TDS) is not needed in PHP, the build line is simpler:
  ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr/local/mysql --prefix=/opt/php-5.2.0 --with-xml --with-libxml-dir=/opt/libxml2 --enable-pcntl --enable-force-cgi-redirect --with-gd --with-zlib-dir --with-ttf --with-freetype-dir --with-ldap
• To allow easier upgrading, rollback or testing new PHP modules, we install into a version specific directory like '/opt/php5.2.0' above, and create links to this directory.

Enable PHP in apache:

Edit your httpd.conf (e.g. /usr/local/apache/conf/httpd.conf) to load the PHP module

    LoadModule php5_module modules/libphp5.so

The path on the right hand side of the LoadModule statement must point to the path of the PHP module on your system. Then "make install" from above may have already added this for you, but be sure to check. Also, tell Apache to parse certain extensions as PHP in httpd.conf
AddType application/x-httpd-php .php .phtml
AddType application/x-httpd-php-source .phps
