一、安装篇
博主注：截至2017-10-10，官网上thrift最新版0.10.0一直无法成功编译。所以，请选择0.9.3版本，避免走各种弯路：
wget http://apache.fayea.com/thrift/0.9.3/thrift-0.9.3.tar.gz
1、安装开发平台工具
yum -y groupinstall "Development Tools"
2、安装autoconf
wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz
tar xvf autoconf-2.69.tar.gz
cd autoconf-2.69
./configure --prefix=/usr/local
make
make install
3、安装automake
wget http://ftp.gnu.org/gnu/automake/automake-1.14.tar.gz
tar xvf automake-1.14.tar.gz
cd automake-1.14
./configure --prefix=/usr/local
make
make install
4、安装bison
wget http://ftp.gnu.org/gnu/bison/bison-2.5.1.tar.gz
tar xvf bison-2.5.1.tar.gz
cd bison-2.5.1
./configure --prefix=/usr/local
make
make install
5、安装C++库依赖包
yum -y install libevent-devel zlib-devel openssl-devel
6、安装boost
wget http://sourceforge.net/projects/boost/files/boost/1.53.0/boost_1_53_0.tar.gz
tar xvf boost_1_53_0.tar.gz
cd boost_1_53_0
./bootstrap.sh
./b2
7、安装其它依赖包
yum install gcc gcc-c++ bzip2 bzip2-devel bzip2-libs python-devel -y
8、安装thrift（基本的编译套路）
cd thrift
./bootstrap.sh
./configure --with-lua=no --prefix=/alidata/server/thrift
make
make install
二、Hello World篇
使用套路总结：
1、用IDL语法，定义自己的数据结构与服务接口：
https://git-wip-us.apache.org/repos/asf?p=thrift.git;a=blob_plain;f=tutorial/tutorial.thrift
https://git-wip-us.apache.org/repos/asf?p=thrift.git;a=blob_plain;f=tutorial/shared.thrift
将这两个文件下载到本地，分别保存为tutorial.thrift和shared.thrift，并将这两个文件传到与thrift同目录下。
附：
IDL详细教程：
http://thrift.apache.org/docs/idl
IDL示例（够用了）：
https://git-wip-us.apache.org/repos/asf?p=thrift.git;a=blob_plain;f=tutorial/tutorial.thrift
https://git-wip-us.apache.org/repos/asf?p=thrift.git;a=blob_plain;f=tutorial/shared.thrift
2、用thrift将上面的thrift的IDL文件，转成对应语言的类：
thrift -gen php:server tutorial.thrift
上面这一句是对应服务端的转换，客户端的转换不用:server；但是服务端方式生成的类文件可以供客户端使用。
3、转换完成后，在本目录下会得到一个gen-php目录，里面有三个文件tutorial.php、shared.php和Types.php。
tutorial.php里面有一个CalculatorIf接口，这个类是我们要实现的服务端业务接口。
shared.php被引用在tutorial.php文件中。
Types.php里面是自定义数据类型。
4、实现server端，即需要创建一个Handler类实再业务接口CalculatorIf
注意：这里的lib文件在thrift源码包lib里，我们移到自己的php需要的路径中。代码中require_once部分、$GEN_DIR部分、Thrift命名空间注册部分的路径需要根据实际情况进行更改
registerNamespace('Thrift', __DIR__ . '/../../lib/php/lib');
$loader->registerDefinition('shared', $GEN_DIR);
$loader->registerDefinition('tutorial', $GEN_DIR);
$loader->register();
if (php_sapi_name() == 'cli') {
ini_set("display_errors", "stderr");
}
use Thrift\Protocol\TBinaryProtocol;
use Thrift\Transport\TPhpStream;
use Thrift\Transport\TBufferedTransport;
class CalculatorHandler implements \tutorial\CalculatorIf {
protected $log = array();
public function ping() {
error_log("ping()");
}
public function add($num1, $num2) {
error_log("add({$num1}, {$num2})");
return $num1 + $num2;
}
public function calculate($logid, \tutorial\Work $w) {
error_log("calculate({$logid}, {{$w->op}, {$w->num1}, {$w->num2}})");
switch ($w->op) {
case \tutorial\Operation::ADD:
$val = $w->num1 + $w->num2;
break;
case \tutorial\Operation::SUBTRACT:
$val = $w->num1 - $w->num2;
break;
case \tutorial\Operation::MULTIPLY:
$val = $w->num1 * $w->num2;
break;
case \tutorial\Operation::DIVIDE:
if ($w->num2 == 0) {
$io = new \tutorial\InvalidOperation();
$io->whatOp = $w->op;
$io->why = "Cannot divide by 0";
throw $io;
}
$val = $w->num1 / $w->num2;
break;
default:
$io = new \tutorial\InvalidOperation();
$io->whatOp = $w->op;
$io->why = "Invalid Operation";
throw $io;
}
$log = new \shared\SharedStruct();
$log->key = $logid;
$log->value = (string)$val;
$this->log[$logid] = $log;
return $val;
}
public function getStruct($key) {
error_log("getStruct({$key})");
// This actually doesn't work because the PHP interpreter is
// restarted for every request.
//return $this->log[$key];
return new \shared\SharedStruct(array("key" => $key, "value" => "PHP is stateless!"));
}
public function zip() {
error_log("zip()");
}
};
header('Content-Type', 'application/x-thrift');
if (php_sapi_name() == 'cli') {
echo "\r\n";
}
$handler = new CalculatorHandler();
$processor = new \tutorial\CalculatorProcessor($handler);
$transport = new TBufferedTransport(new TPhpStream(TPhpStream::MODE_R | TPhpStream::MODE_W));
$protocol = new TBinaryProtocol($transport, true, true);
$transport->open();
$processor->process($protocol, $protocol);
$transport->close();
5、实现client端：
同样需要注意：这里的lib文件在thrift源码包lib里，我们移到自己的php需要的路径中。代码中require_once部分、$GEN_DIR部分、Thrift命名空间注册部分的路径需要根据实际情况进行更改
registerNamespace('Thrift', __DIR__ . '/../../lib/php/lib');
$loader->registerDefinition('shared', $GEN_DIR);
$loader->registerDefinition('tutorial', $GEN_DIR);
$loader->register();
use Thrift\Protocol\TBinaryProtocol;
use Thrift\Transport\TSocket;
use Thrift\Transport\THttpClient;
use Thrift\Transport\TBufferedTransport;
use Thrift\Exception\TException;
try {
if (array_search('--http', $argv)) {
$socket = new THttpClient('localhost', 8080, '/php/PhpServer.php');
} else {
$socket = new TSocket('localhost', 9090);
}
$transport = new TBufferedTransport($socket, 1024, 1024);
$protocol = new TBinaryProtocol($transport);
$client = new \tutorial\CalculatorClient($protocol);
$transport->open();
$client->ping();
print "ping()\n";
$sum = $client->add(1,1);
print "1+1=$sum\n";
$work = new \tutorial\Work();
$work->op = \tutorial\Operation::DIVIDE;
$work->num1 = 1;
$work->num2 = 0;
try {
$client->calculate(1, $work);
print "Whoa! We can divide by zero?\n";
} catch (\tutorial\InvalidOperation $io) {
print "InvalidOperation: $io->why\n";
}
$work->op = \tutorial\Operation::SUBTRACT;
$work->num1 = 15;
$work->num2 = 10;
$diff = $client->calculate(1, $work);
print "15-10=$diff\n";
$log = $client->getStruct(1);
print "Log: $log->value\n";
$transport->close();
} catch (TException $tx) {
print 'TException: '.$tx->getMessage()."\n";
}
?>
6、因为php的server端代码没有进行端口侦听的网络服务功能，所以要依靠python来提供这个功能。我们把下面的脚本命名为s.py，需要与server.php放在同一个目录下（/alidata/www/thrift）
#!/bin/py
#coding=utf-8
import os
import BaseHTTPServer
import CGIHTTPServer
# chdir(2) into the tutorial directory.
os.chdir('/alidata/www/thrift')
# 指定目录 ，如果目录错误 请求会失败
class Handler(CGIHTTPServer.CGIHTTPRequestHandler):
cgi_directories = ['/']
BaseHTTPServer.HTTPServer(('', 8080), Handler).serve_forever()
7、到现在为止，hello world级别的工程已经完成。
运行服务端s.py
运行客户端php client.php --http
便可以看到响应的实际效果
三、生产使用篇
hello world级别的工程，只有一个进程进行侦听和服务，在多核CPU的时代，只有一个进程不但无法充分利用CPU的性能，也无法为用户提供最高效的服务。
方案一：用php自己实现网络服务方案（这是一个牛人写的多进程服务demo，完全可以参照） http://blog.csdn.net/flynetcn/article/details/47837975

方案二：方案一固然不错，但是因为没有实践的检验，所以用起来还是有一点担心的。所以，个人建议采用workman的thrift方案，请参考：http://www.workerman.net/workerman-thrift
1、因为要使用多进程，所以需要先安装pcntl扩展。（安装过程很简单，不是重点，不详细描述过程）
2、workman-thrift下载解压后，目录中Applications/ThriftRpc/Services存放的自己的服务端服务，即业务接口If、自定义数据类型Type和业务接口的实现。
3、根目录下的start.php加载并运行了Applications下的各个服务的start.php文件
4、解压后的目录中Applications/ThriftRpc是一个HelloWorld服务的demo。
5、现在，看Applications/ThriftRpc/start.php中的关键代码：
$worker = new ThriftWorker('tcp://0.0.0.0:9090');
$worker->count = 16;
$worker->class = 'HelloWorld';
这里，设置了侦听的IP与端口、设置了服务进程数量与服务的类
6、查看Applications/ThriftPrc/ThriftWorker.php中的关键代码：
// 载入该服务下的所有文件
foreach(glob(THRIFT_ROOT . '/Services/'.$this->class.'/*.php') as $php_file)
{
require_once $php_file;
}
// 检查类是否存在
$processor_class_name = "\\Services\\".$this->class."\\".$this->class.'Processor';
if(!class_exists($processor_class_name))
{
ThriftWorker::log("Class $processor_class_name not found" );
return;
}
// 检查类是否存在
$handler_class_name ="\\Services\\".$this->class."\\".$this->class.'Handler';
if(!class_exists($handler_class_name))
{
ThriftWorker::log("Class $handler_class_name not found" );
return;
}
根据第5步指定的class，在ThriftWorker中会载入对应路径下的所有php文件进行检查，并检查对应的Processor和Handler类是否存在。最终创建Handler和Processor
7、运行根目录下的php start.php start，可以看到
恭喜，服务端运行成功。
8、关于客户端
复制 http://www.workerman.net/workerman-thrift 上的客户端代码，即可正常运行。
array(
'addresses' => array(
'127.0.0.1:9090',
'127.0.0.2:9191',
),
'thrift_protocol' => 'TBinaryProtocol',//不配置默认是TBinaryProtocol，对应服务端HelloWorld.conf配置中的thrift_protocol
'thrift_transport' => 'TBufferedTransport',//不配置默认是TBufferedTransport，对应服务端HelloWorld.conf配置中的thrift_transport
),
'DInfoCenter' => array(
'addresses' => array(
'127.0.0.1:9090',
),
'thrift_protocol' => 'TBinaryProtocol',//不配置默认是TBinaryProtocol，对应服务端HelloWorld.conf配置中的thrift_protocol
'thrift_transport' => 'TBufferedTransport',//不配置默认是TBufferedTransport，对应服务端HelloWorld.conf配置中的thrift_transport
),
)
);
// ========= 以上在WEB入口文件中调用一次即可 ===========
// ========= 以下是开发过程中的调用示例 ==========
// 初始化一个HelloWorld的实例
$client = ThriftClient::instance('HelloWorld');
// --------同步调用实例----------
var_export($client->sayHello('JIM');
//var_export($client->recv_request("req",strval(time())));
// --------异步调用示例-----------
/*
// 异步调用 之 发送请求给服务端（注意：异步发送请求格式统一为 asend_XXX($arg),既在原有方法名前面增加'asend_'前缀）
$client->asend_sayHello("JERRY");
$client->asend_sayHello("KID");
// 这里是其它业务逻辑
sleep(1);
// 异步调用 之 接收服务端的回应（注意：异步接收请求格式统一为 arecv_XXX($arg),既在原有方法名前面增加'arecv_'前缀）
var_export($client->arecv_sayHello("KID"));
var_export($client->arecv_sayHello("JERRY"));
*/
9、截止这里，已经可以成功运行workman-thrift的hello world工程
10、关于定义自己的服务：
到这里根据了解，我们可以很容易自己的的服务。比如，我们想定义自己的服务，DInfoCenter，这个过程中有三个一定需要注意的地方：
第一点：目录名称需要改成DInfoCenter
第二点：三个文件的namespace声明（第一行），一定要改为：namespace Services\DInfoCenter;
第三点：默认生成的DInfoCenter.php中，下面很多类以及函数的调用，都带有命名空间（\DInfoCenter），需要把这一段删掉
到这里，就大致完成了，最后将start.php中的class赋值成DInfoCenter，就全部完成了。
