php7安装 event扩展

1 下载地址：http://pecl.php.net/package/event

2 安装支持库libevent，需要编译高版本（这里以最新版本release-2.1.8-stable为例）

https://github.com/nmathewson/Libevent.git

./configure --prefix=/usr/local/libevent-2.1.8
make
sudo make install

3 安装event库

  下载地址: http://pecl.php.net/package/event   

wget http://pecl.php.net/get/event-2.3.0.tgz
tar -zxvf event-2.3.0.tgz

/usr/local/php-7.1.8/bin/phpize

生成 Makefile，同时指定安装路径，为下一步的编译做准备

./configure --with-php-config=/usr/local/php-7.1.8/bin/php-config --with-event-libevent-dir=/usr/local/libevent-2.1.8/

修改php.ini
