系统环境：
Redhat 9.0
Apache-1.3.27
Mysql3.23-54a-11
Php-4.32
j2sdk1.4.1_03
安装配置：
1．mysql使用的是redhat9自带的rpm包，不介绍安装了，jdk的安装也很简单，我们把jdk安装到/usr/java/j2sdk1.4.1_03 并在/etc/profile设置jdk环境参数。
2．编译安装apache
tar zvxf apache_1.3.27.tar.gz
cd apache_1.3.27
./configure –prefix=/usr/local/apache –enable-module=so –enable-shared=max
make
make install
3．编译安装php
tar zvxf php-4.3.2.tar.gz
cd php-4.3.2
./configure –prefix=/usr/local/php –with-mysql \
--with-apxs=/usr/local/apache/bin/apxs \
--with-java=/usr/java/j2sdk1.4.1_03
make
make install
修改/usr/local/apache/conf/httpd.conf
查找
在此范围添加
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
4．配置php.ini
cp php.ini.dist /usr/local/php/lib/php.ini
vim php.ini
修改如下内容：
[Java]
java.class.path = /usr/local/php/lib/php/php_java.jar
java.home = /usr/java/j2sdk1.4.1_03
java.library = /usr/java/j2sdk1.4.1_03/jre/lib/i386/libjava.so
java.library.path =/usr/local/php/lib/php/extensions/no-debug-non-zts-20020429
extension_dir = /usr/local/php/lib/php/extensions/no-debug-non-zts-20020429
extension=java.so
保存退出。
cd /usr/local/php/lib/php/extensions/no-debug-non-zts-20020429
ln –s java.so libphp_java.so 这一步很重要哦！
设置环境变量：
export LD_LIBRARY_PATH=/usr/java/j2sdk1.4.1_03/jre/lib/i386:/usr/java/j2sdk1.4.1_03/jre/lib/i386/server
ok!重启一下apache
/usr/local/apache/bin/apachectl start
测试一下，写个测试页test.php
<?
$system=new Java("java.lang.System");
//demonstrate property access
print 'Java version='.$system->getProperty('java.version').' <br>';
?>
