如何在 CentOS 6.7 的 PHP 5.6.13 中启用 pthreads？

Question

我通过 IUS 存储库在 CentOS 6.7 上安装了 PHP 5.6.13。这是php -v 命令的输出：

# php -v
PHP 5.6.13 (cli) (built: Sep  3 2015 11:54:03)

    with Xdebug v2.3.3, Copyright (c) 2002-2015, by Derick Rethans

为了安装和启用pthreads，我按照以下步骤操作：

1. 搜索合适的包：

   # yum search pthreads
   ================================= N/S Matched: pthreads ===============================
   mingw32-winpthreads-static.noarch : Static version of the MinGW Windows pthreads library
   mingw64-winpthreads-static.noarch : Static version of the MinGW Windows pthreads library

   php56u-pecl-pthreads-debuginfo.x86_64 : Debug information for package php56u-pecl-pthreads
   mingw32-winpthreads.noarch : MinGW pthread library for the win32 target
   mingw64-winpthreads.noarch : MinGW pthread library for the win64 target

   openblas-threads.x86_64 : An optimized BLAS library based on GotoBLAS2, pthreads version
   php55u-pecl-pthreads.x86_64 : Threading API
   php56u-pecl-pthreads.x86_64 : Threading API
   

2. 安装包：

   #yum install php56u-pecl-pthreads.x86_64

3. 找到.so 所在的位置：

   #locate pthreads.so
   /usr/lib64/php-zts/modules/pthreads.so
   

4. 通过尝试以下每一行在/etc/php.ini 启用：

   extension=pthreads.so
   extension=/usr/lib64/php-zts/modules/pthreads.so
   zend_extension=pthreads.so
   zend_extension=/usr/lib64/php-zts/modules/pthreads.so
   

5. 重新启动 Apache 并查找模块

   # php -m | grep pthreads
   Failed loading /usr/lib64/php-zts/modules/pthreads.so:  /usr/lib64/php-zts/modules/pthreads.so: undefined symbol: core_globals_id
   

并且总是失败并显示上述消息。我做错了什么？

注意：我通过运行phpinfo() 注意到Thread Safety 已禁用，我是否需要启用此功能才能正确加载库？

Answer 1

由于某种原因，有两个不同的版本，您安装的一个会导致与您的 PHP 版本发生冲突。与用于构建 PHP 本身的编译选项相比，用于 pthreads.so 的编译选项不匹配。

php56u-pecl-pthreads.x86_64 0:2.0.10-2.ius.el6

您应该从相同的源/版本中删除和安装所有内容。 这是我唯一能想到的。
