在CentOS上搭建PHP 5.3.8、Nginx 1.0.9和MySQL 5.5.17的详细配置步骤如下：
更新系统
确保你的系统是最新的。
sudo yum update y
安装必要的依赖包
sudo yum install y gcc gccc++ make zlibdevel openssldevel curldevel libxml2devel bzip2devel
安装MySQL 5.5.17
下载并安装MySQL
cd /usr/local/src wget http://downloads.mysql.com/archives/get/p/23/file/mysql5.5.17.tar.gz tar zxvf mysql5.5.17.tar.gz cd mysql5.5.17 cmake . make sudo make install
初始化数据库
sudo scripts/mysql_install_db user=mysql basedir=/usr/local/mysql datadir=/usr/local/mysql/data
配置MySQL
编辑/etc/my.cnf文件，添加以下内容：
[mysqld] basedir = /usr/local/mysql datadir = /usr/local/mysql/data socket = /tmp/mysql.sock user = mysql symboliclinks = 0 [mysqld_safe] logerror = /var/log/mysqld.log pidfile = /var/run/mysqld/mysqld.pid
启动MySQL服务
sudo cp supportfiles/mysql.server /etc/init.d/mysql sudo service mysql start
设置root密码
/usr/local/mysql/bin/mysqladmin u root password 'yourpassword'
安装PHP 5.3.8
下载并安装PHP
cd /usr/local/src wget http://museum.php.net/php5/php5.3.8.tar.gz tar zxvf php5.3.8.tar.gz cd php5.3.8 ./configure prefix=/usr/local/php withconfigfilepath=/usr/local/php enablembstring withmysql=/usr/local/mysql withopenssl withzlib withcurl enablefpm make sudo make install
配置PHP
编辑/usr/local/php/etc/php.ini文件，根据需要修改配置，启用常用扩展：
extension=mysql.so extension=mysqli.so extension=pdo_mysql.so
安装Nginx 1.0.9
下载并安装Nginx
cd /usr/local/src wget http://nginx.org/download/nginx1.0.9.tar.gz tar zxvf nginx1.0.9.tar.gz cd nginx1.0.9 ./configure prefix=/usr/local/nginx withhttp_ssl_module withpcre withhttp_fastcgi_module withhttp_gzip_static_module make sudo make install
配置Nginx
编辑/usr/local/nginx/conf/nginx.conf文件，添加以下内容：
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octetstream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.php index.html index.htm;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
}启动Nginx服务
sudo /usr/local/nginx/sbin/nginx
配置PHPFPM
编辑/usr/local/php/etc/phpfpm.conf文件，添加以下内容：
[www] listen = 127.0.0.1:9000 user = nobody group = nobody pm = dynamic pm.max_children = 50 pm.start_servers = 5 pm.min_spare_servers = 5 pm.max_spare_servers = 35 chdir = /
启动PHPFPM服务：
sudo /usr/local/php/sbin/phpfpm
测试安装
创建一个PHP测试文件来验证安装是否成功。
echo "<?php phpinfo(); ?>" > /usr/local/nginx/html/index.php
访问http://your_server_ip，你应该能看到PHP信息页面。
步骤涵盖了在CentOS上安装和配置PHP 5.3.8、Nginx 1.0.9和MySQL 5.5.17的基本过程，请根据你的具体需求进行进一步的配置和优化。
