php添加pcntl扩展(Linux)

pcntl扩展可以支持php的多线程操作(仅限linux)
原本需要重新编译PHP的后面configrue提示加上--enable-pcntl

由于我的php是采用yum安装的,所以不能采用上面的方式
下面介绍一个php动态添加扩展的方式 phpize

1、首先看下 phpize命令 所在的目录  (ps:我的目录/usr/bin/phpize)
如果没有找到的话 执行安装

yum install php53_devel   (ps:请注意自己的版本)
Copy after login


安装完毕后。会生成phpize命令

2、去php.net下载相应版本的php源文件
咱们以php-5.3.17 为例吧,解压后,进入相应的模块下

cd ext/pcntl
#先执行phpize
/usr/bin/phpize
./configure --with-php-config=/usr/bin/php-config   (ps:请正确的指定php-config的目录)
#编译、安装
make && make install
Copy after login


这时候出了一个错误

./configure编译正常,但make出错
error: ‘PHP_FE_END’ undeclared here (not in a function)

解决方法:

源代码有错误,进入php-5.3.17目录
sed -i 's|PHP_FE_END|{NULL,NULL,NULL}|' ./ext/**/*.c
sed -i 's|ZEND_MOD_END|{NULL,NULL,NULL}|' ./ext/**/*.c
再重新make && make install

3、编译完毕后会生成了一个 pcntl.so的文件。在php的model目录里

编辑/etc/php.ini,加入

extension=pcntl.so
Copy after login



4、重启apache

service httpd restart
Copy after login


5、测试是否安装成功

echo pcntl_fork();
Copy after login


输出:23165
