# mkdir php

# cd php
# apt-get source php5
# cd php5-(WHATEVER_RELEASE)/ext/pcntl
# phpize
# ./configure (注一)
# make
# make install

7.复制pcntl/module文件夹下的pcntl.so文件到自定义位置

8.在php.ini文件中添加extension=上一步自定义位置/pcntl.so

9.重启apache

如报错误：

sed -i 's|PHP_FE_END|{NULL,NULL,NULL}|' ./ext/pcntl/*.c

sed -i 's|ZEND_MOD_END|{NULL,NULL,NULL}|' ./ext/pcntl/*.c

注一：./configure --with-php-config=/opt/app/php5/bin/php-config

phpize：yum install php-devel  或者 apt-get install php5-dev #提供phpize命令支持

注意版本，必须用当前PHP版本的phpize  /opt/app/php5/bin/phpize
