yum install php-devel php-pear httpd-devel

( make -j3 && make -j3 install) -> Faster building
cp php.ini-development /etc/php.ini
pecl install pthreads
提示错误
error: pthreads requires ZTS, please re-compile PHP with ZTS enabled
不对啊  我加了安全线程参数了  怎么还报错。。。
好像刚才用yum安装php-devel的时候安装了php
于是
yum remove php
 重新编译在安装

pecl install pthreads
提示错误  ERROR: `phpize' failed
cd /usr/local/php/bin/
查看是否有phpize
发现有phpize,说明不是php-devel的问题
是安装扩展的方式出了问题，所以php安装是没有问题的
下载pthreads扩展包
unzip pthreads-master.zip
cd pthreads
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install
提示Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-zts-20121212/
说明安装成功
修改php.ini文件,添加extension=pthreads.so
echo "extension=pthreads.so" >> /etc/php.ini
php -v
提示Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/pthreads.so' - /usr/lib64/php/modules/pthreads.so: cannot open shared object file: No such file or directory in Unknown on line 0
尼玛都没一件顺心的安装
错误    我擦
查看一下 /usr/local/php/include/php/main/php_config.php 里面是否有#define ZTS 1
里面有这个啊 我擦   这是什么问题呢    继续百度

重新安装一次试试看

cd php-5.5.8.tar.gz

./configure --prefix=/usr/local/php --with-config-file-path=/etc --enable-maintainer-zts

make -j3 && make -j3 install

cp php.ini-development /etc/php.ini

进入pthreads解压目录
cd ~/soft/pthreads-master
运行phpize脚本
/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config

make && make install
提示安装成功
echo "extension=pthreads.so" >> /etc/php.ini
php -v

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/pthreads.so' - /usr/lib64/php/modules/pthreads.so: undefined symbol: core_globals_id in Unknown on line 0

尼玛还是同样的错误   不知道了

本人php版本是5.4.17的所以下载php_pthreads-0.1.0-5.4-ts-vc9-x86.zip文件包，其中0.1.0表示为当前pthreads版本号，5.4为php版本号，ts就是之前判断php对应的ts、nts版，vs9代表是Visual Studio 2008 compiler编译器编译的，最后的x86代表的是32位的版本。

1、修改php.ini文件 添加extension=php_pthreads.dll
2、将php_pthreads.dll放到C:\wamp\bin\php\php5.5.12\ext下面
