我需要有关如何：在 Ubuntu PHP 中启用 PCNTL 的帮助。

$ mkdir /tmp/phpsource
$ cd /tmp/phpsource


$ wget http://museum.php.net/php5/php-5.3.2.tar.gz
$ tar xvf php-5.3.2.tar.gz
$ cd php-5.3.2/ext/pcntl


$ phpize   -bash: phpize: command not found

一切都很顺利，直到我尝试运行 phpize！然后我得到错误'-bash：phpize：找不到命令'？？有任何想法吗？

更新运行：

$ sudo apt-get update

然后跑：

$ sudo apt-get install php5-dev

在尼克的帮助下，我设法完成了这个程序。但是'make test'失败了？？？

$ phpize
$ ./configure
$ make

$ cp modules/pcntl.so /usr/lib/php5/20090626/
$ echo "extension=pcntl.so" > /etc/php5/conf.d/pcntl.ini

$ make test - FAILED!

帮助：我输入了 'echo "extension=pcntl.so > /etc/php5/conf.d/pcntl.ini' 而不是 'echo "extension=pcntl.so" > /etc/php5/conf.d/pcntl.ini ' 我第一次运行这个。那很糟糕吗？

这是我在 Ubuntu 12.04 中发现的：

  • 检查您的 PHP.ini 是否有被禁用的 pnctl 函数。

    disable_functions =     pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited,pcntl_wifstopped,pcntl_wifsignaled,pcntl_wexitstatus,pcntl_wtermsig,pcntl_wstopsig,pcntl_signal,pcntl_signal_dispatch,pcntl_get_last_error,pcntl_strerror,pcntl_sigprocmask,pcntl_sigwaitinfo,pcntl_sigtimedwait,pcntl_exec,pcntl_getpriority,pcntl_setpriority

  • phpinfo 报告该函数已加载，但如果不将 pcntl.ini 文件放入 /etc/php5/conf.d，它将无法实际工作。

可悲的是，每次 /etc/cron.d 中的 PHP 会话清理 cron 启动时，这都会导致“模块已加载”错误，但是如果没有这两个部分，PCNTL 将无法运行，到目前为止我还没有找到一个好的禁用“已加载”错误的解决方案。它凌乱，丑陋，并且向我的根邮件发送垃圾邮件，当我找到解决方案时，我会发布它。到目前为止，我只在 12.04 中遇到过这个问题。

更新

我破解了我的 /usr/lib/php5/maxlifetime 脚本文件以停止发送带有 pnctl 错误的垃圾邮件（PHP 警告：模块 'pcntl' 已加载到第 0 行的未知中）。这是我的编辑 - 我专门在“E_DEPRECATED”行中添加了以使消息静音。

第 8 行：

    cur=$(php5 -c /etc/php5/${sapi}/php.ini -d "error_reporting='E_ALL & ~E_DEPRECATED'" -r 'print ini_get("session.gc_maxlifetime");' 2> /dev/null)

有一些这样的步骤：（我的操作系统是debian7.2 xfce x86）。

1：我这样安装 pcntl

#mkdir php
#cd php 
#apt-get source php5 
#cd php5-5.4.4/ext/pcntl
#phpize
#./configure
#make
#echo "extension=pcntl.so" > /etc/php5/mods-available/pcntl.ini
#ln -s /etc/php5/mods-available/pcntl.ini /etc/php5/conf.d/pcntl.ini

2：重启nginx或apache2时，php得到一个警告。

“PHP 警告：模块 'pcntl' 已在第 0 行的未知中加载”

3：所以我

“rm -rf /etc/php5/mods-available/pcntl.ini 和 /etc/php5/conf.d/pcntl.ini”

4：编辑“php.ini”文件。

a.apache2, it's in "/etc/php5/apache2/php.ini"
b.cgi like nginx,it's in "/etc/php5/cgi/php.ini"

使

"disable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited..."
comments, add  " ; "  in front of "disable_functions".

重新启动你的服务器，警告消失了。祝你好运。

在我的带有 ubuntu 12.10（以及更早版本）的开发机器上，pcntl 已启用/已启用。

$ php -m | grep pcntl
pcntl

我想这就是问题所在：

PHP 警告：模块 'pcntl' 已加载到第 0 行的未知中

所以不要再次安装它。

在 Ubuntu 15.04 中，pcntl 安装在 php CLI 中，但默认禁用。要启用，请编辑 /etc/php5/cli/php.ini 并注释掉该行：

disable_functions = pcntl_alarm,pcntl_fork,pcntl_waitpid,pcntl_wait,pcntl_wifexited,pcntl_wifstopped,pcntl_wifsignaled,pcntl_wexitstatus,pcntl_wtermsig,pcntl_wstopsig,pcntl_signal,pcntl_signal_dispatch,pcntl_get_last_error,pcntl_strerror,pcntl_sigprocmask,pcntl_sigwaitinfo,pcntl_sigtimedwait,pcntl_exec,pcntl_getpriority,pcntl_setpriority,

如果您希望在 apache2 中启用这些，则编辑文件 /etc/php5/apache2/php.ini 并进行相同的更改。

建议只删除您需要使用的功能，以尽可能多地保留安全限制。
