Installation and configuration of php5 and mysql5

Select the dynamic addition module of apache2, compile on redhat linux 9, and install the non-CGI version of PHP

The software packages I used:

apache 2.0.54
php 5.1.4
zlib 1.2.3
mysql 5.0.22
libxml2 2.6.26

Problems encountered:

1. mysql has been installed locally

Countermeasures: rpm -e --nodeps mysql-VERSION-NUMBER. The rest of the software is similar

2. The zlib version is too low

Countermeasures: Download a new version to install, such as zlib-1.2.3.tar.tar

3. The version of mysql cannot be It is the installed version mysql-standard-5.0.22-linux-i686.tar.gz with a static library, otherwise PHP cannot configure

Countermeasures: Download the source code and compile it, such as mysql-5.0.22.tar. gz

4. Do not compile on the disk mounted, especially in NTFS format, otherwise inexplicable errors will occur

5. Mysql configure command, excerpted from mysql-5.0.22.tar INSTALL file in .gz

CFLAGS="-O3" CXX=gcc CXXFLAGS="-O3 -felide-constructors /
            -fno-exceptions -fno-rtti" ./configure /
            --prefix=/usr/local/mysql --enable-assembler /
            --with-mysqld-ldflags=-all-static

6. PHP configure command

./configure /
--disable-cgi /
--with-apxs2=/usr/local/apache2/bin/apxs /
--with-mysql=/usr/local/mysql /
--with-xml /
--with-dom /
--with-zlib /
--with-libxml /
--enable-inline-optimization /
--enable-safe-mode /
--enable-track-vars /
--enable-trans-sid /
--enable-xml /
--enable-libxml /
--enable-so

7. Since the lib library on each machine is different, there may be problems when loading libphp5.so in apache2 Some symbols undefined

Countermeasures: Change the --enable and --with options in configure. Add --disable-all if necessary. Note that --disable-all does not install php5-extension, which is compatible with perl, and will make many functions unable to run.

Other points to note can be found in the INSTALL files of each installation package and online articles. For example

web server-apache2+php5+mysql5 for linux::Apache  
web server-apache2+php5+mysql5 for linux OS::Php
web server-apache2+php5+mysql5 for linux::Mysql
web server-apache2+php5+mysql5 for windows OS
