更新yum源 见CentOS

cd /etc/yum.repos.d
mv CentOS-Base.repo  CentOS-Base.repo.save
wget http://centos.ustc.edu.cn/CentOS-Base.repo.5
mv CentOS-Base.repo.5 CentOS-Base.repo

更新yum

yum -y update

安装常用包

yum install -y ntp vim-enhanced gcc gcc-c++ gcc-g77 flex bison autoconf automake bzip2-devel ncurses-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel pam-devel kernel

注意： 使用yum方式安装apache和php会存在以下问题：

• php的版本只有5.1 。使用phpmyadmin会提示版本太低，不让使用
• apache 无法使用虚拟主机，指定主目录会提示目录不存在，无访问权限

建议全新安装php+mysql+apache

• mysql: 在 http://dev.mysql.com/downloads/ 下载 mysql-5.0.83-linux-i686.tar.gz
• apache2
• php5 http://cn.php.net/
• eaccelerator http://eaccelerator.net/
• memcached http://www.danga.com/memcached/download.bml

yum list mysql*
yum -y install mysql.i386 mysql-devel.i386 

yum -y install php php-devel php-mcrypt php-mbstring php-gd php-mysql

./configure  --enable-eaccelerator=shared  --with-php-config=/usr/bin/php-config 

• 下载：http://www.danga.com/memcached/download.bml
• 安装libevent

   yum -y install libevent libevent-devel

• ./configure --with-libevent=/usr
  make
  make install 

• 启动：

   /usr/local/bin/memcached -d -m 512 -p 11211 -u root   

• memcache PHP模块下载地址 http://pecl.php.net/package/memcache

•  /usr/bin/phpize
  ./configure --enable-memcache --with-php-config=/usr/bin/php-config --with-zlib-dir
  make
  make install

• ./configure --enable-eaccelerator=shared --with-php-config=/usr/bin/php-config 
  make
  make install
  
  mkdir /tmp/eaccelerator && chmod 777 /tmp/eaccelerator && touch /var/log/eaccelerator_log
