先编译apache2,并安装

./configure --prefix=/usr/local/apache --enable-module=most --enable-shared=max --enable-so

再编译freetype2和libpng,以启用GD,这两个都简单,

然后再编译php4.3.11,

./configure --with-apxs2=/usr/local/apache/bin/apxs --with-mysql --enable-calendar --enable-force-cgi-redirect --enable-gd-imgstrttf --enable-gd-native-ttf --enable-inline-optimization --enable-magic-quotes --enable-memory-limit --with-bz2 --with-ftp --with-png-dir=/usr --with-xml --with-zlib=yes --with-gd=yes --enable-mbstring --with-png-dir=/usr --with-ttf --with-freetype-dir=/usr/local --enable-ctype --enable-dbase --enable-ftp --with-ftp --with-gdbm --with-gettext --with-tiff-dir=/usr
这个已经自动在

/usr/local/apache/conf/httpd.conf里加入了php4支持.

LoadModule php4_module        modules/libphp4.so
      AddType application/x-httpd-php .php .phtml

记得,/usr/lib/httpd/modules/libphp4.so是FC3自带的php4.3.9的,不要用了.然后

cp ./php.ini-dist /usr/local/lib/php.ini

建立一个放session的目录,比如

mkdir /tmp/session,并chmod 777 /tmp/session,

session.sav_path = /tmp/session

在apache增加虚拟主机支持

NameVirtualHost *:80/usr/local/lib/php.ini

<VirtualHost *:80>
ServerAdmin webmaster@www.my.com
DocumentRoot /var/www/www.my.com/
ServerName www.my.com
ErrorLog logs/www.my.com-error_log
CustomLog logs/www.my.com-access_log common
</VirtualHost>

加入默认页

DirectoryIndex index.html index.html.var index.php

用/usr/local/apache/bin/apachectl start启动，用phpinfo观察，

写一个测试gd的脚本，

<?php

function make_seed()
{
list($usec, $sec) = explode(' ', microtime());
return (float) $sec + ((float) $usec * 100000);
}

// 生成 4 位随机数
mt_srand(make_seed());

$number = '';
$number_len = 4;
$stuff = '120129109381209573475647863012381290137092174826578631203182308120128390217421075';
$stuff_len = strlen($stuff) - 1;
for ($i = 0; $i < $number_len; $i++) {
$number .= substr($stuff, mt_rand(0, $stuff_len), 1);
}

// 把随机数存入 session
$_SESSION['VERIFY_CODE'] = $number;

// 生成验证码图片
$img_width = 40;
$img_height = 18;

$img = imageCreate($img_width, $img_height);
ImageColorAllocate($img, 0x6C, 0x74, 0x70);
$white = ImageColorAllocate($img, 0xff, 0xff, 0xff);

$ix = 5;
$iy = 2;
for ($i = 0; $i < $number_len; $i++) {
imageString($img, 3, $ix, $iy, $number[$i], $white);
$ix += 8;
}

// 输出图片
header("Content-type: " . image_type_to_mime_type(IMAGETYPE_PNG));
imagepng($img);
imagedestroy($img);

?>

再发一个简单点的，就是太黑了，要改才行，

<?php
/*
 *   Filename: authimg.php
 *   Author:   hutuworm
 *   Date:     2003-04-28
 *   @Copyleft hutuworm.org
 */
//生成验证码图片
Header("Content-type: image/PNG");
srand((double)microtime()*1000000);
$im = imagecreate(62,20);
$black = ImageColorAllocate($im, 0,0,0);
$white = ImageColorAllocate($im, 255,255,255);
$gray = ImageColorAllocate($im, 200,200,200);
imagefill($im,68,30,$gray);
while(($authnum=rand()%100000)<10000);
//将四位整数验证码绘入图片
imagestring($im, 5, 10, 3, $authnum, $black);
for($i=0;$i<200;$i++)   //加入干扰象素
{
    $randcolor = ImageColorallocate($im,rand(0,255),rand(0,255),rand(0,255));
    imagesetpixel($im, rand()%70 , rand()%30 , $randcolor);
}
ImagePNG($im);
ImageDestroy($im);
?>

看到图片，说明成功了，再测试一下可写文件不，

<?php
$tmpfile='/var/www/www.gy12345.com/shop/1.txt';
echo "will open file<br>";
        $fp=fopen($tmpfile, "w");
        if($fp) {

        flock($fp, LOCK_EX);
        fwrite($fp,' dddd');
        flock($fp, LOCK_UN);
        fclose($fp);

echo "ok";

        }
else{
echo 'open fail';
}
?>

可以再测试一下smarty模板和数据库连接
