php多线程安装pthreads方法有一点复杂了,下面的安装步骤有一些多,希望能帮助到各位.
PHP扩展下载:https://github.com/krakjoe/pthreads
PHP手册文档:http://php.net/manual/zh/book.pthreads.php
安装脚本,代码如下:
- #!/bin/sh
- cd /web/soft/php
- if [ -d "pthreads-master" ];then
- rm -rf pthreads-master
- fi
- unzip pthreads-master.zip
- cd pthreads-master
- /web/server/php/bin/phpize
- ./configure --with-php-config=/web/server/php/bin/php-config
- make
- make install
- rm -rf pthreads-master
- PHPINI="/web/server/php/etc/php.ini"
- sed -i '907a extension = "pthreads.so"' $PHPINI
- #更新php-fpm配置
- sed -i 's%;pid = run/php-fpm.pid%pid = run/php-fpm.pid%' /web/server/php/etc/php-fpm.conf
- sed -i 's%;error_log = log/php-fpm.log%error_log = log/php-fpm.log%' /web/server/php/etc/php-fpm.conf
- #杀死php-fpm进程
- ps aux | grep "php" | grep -v "grep" | awk '{print $2}' | xargs -i kill -9 {}
- #启动php-fpm
- /web/server/php/sbin/php-fpm
在安装过程中出现错误:
configure: WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers
解决方法是安装或升级re2c 0.13.4以上版本。
下面我们用rpm包安装此库:
- centos-5 32位:http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el5.rf.i386.rpm
- centos-5 64位:http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el5.rf.x86_64.rpm
- centos-6 32位:http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el6.rf.i686.rpm
- centos-6 64位:http://pkgs.repoforge.org/re2c/re2c-0.13.5-1.el6.rf.x86_64.rpm
- configure: error: pthreads requires ZTS, please re-compile PHP with ZTS enabled
原因:我在编译php的时候没有加入 --enable-maintainer-zts,这个必须要重新编译php,不能动态加载的.
于是我重新编译了php,在原来的编译参数基础上那个加入了 --enable-maintainer-zts ,重新编译安装php即可.
以下为一个示例,代码如下:
- class test_thread_run extends Thread
- {
- public $url;
- public $data;
- public function __construct($url)
- {
- $this->url = $url;
- }
- public function run()
- {
- if(($url = $this->url))
- {
- <?Php
- $this->data = model_http_curl_get($url);
- }
- }
- }
- function model_thread_result_get($urls_array)
- {
- foreach ($urls_array as $key => $value)
- {
- $thread_array[$key] = new test_thread_run($value["url"]);
- $thread_array[$key]->start();
- }
- foreach ($thread_array as $thread_array_key => $thread_array_value)
- {
- while($thread_array[$thread_array_key]->isRunning())
- {
- usleep(10);
- }
- if($thread_array[$thread_array_key]->join())
- {
- $variable_data[$thread_array_key] = $thread_array[$thread_array_key]->data;
- }
- }
- return $variable_data;
- }
- function model_http_curl_get($url,$userAgent="")
- {
- $userAgent = $userAgent ? $userAgent : 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2)';
- $curl = curl_init();
- curl_setopt($curl, CURLOPT_URL, $url);
- curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
- curl_setopt($curl, CURLOPT_TIMEOUT, 5);
- curl_setopt($curl, CURLOPT_USERAGENT, $userAgent);
- $result = curl_exec($curl);
- curl_close($curl);
- return $result;
- }
- for ($i=0; $i < 100; $i++)
- {
- $urls_array[] = array("name" => "baidu", "url" => "http://www.111cn.net/ s?wd=".mt_rand(10000,20000));
- }
- $t = microtime(true);
- $result = model_thread_result_get($urls_array);
- $e = microtime(true);
- echo "多线程:".($e-$t)."\n";
- $t = microtime(true);
- foreach ($urls_array as $key => $value)
- {
- $result_new[$key] = model_http_curl_get($value["url"]);
- }
- $e = microtime(true);
- echo "For循环:".($e-$t)."\n";
- ?>
