一·、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)
1.
wget -c https://github.com/libevent/libevent/releases/download/release-2.1.8-stable/libevent-2.1.8-stable.tar.gz -P /usr/local/src
2.
cd /usr/local/src
3.
tar -zxvf libevent-2.1.8-stable.tar.gz && cd libevent-2.1.8-stable
4.
./configure --prefix=/usr/local/libevent-2.1.8
5.
make && make install
二、安装event库(以event-2.3.0.tgz为例)
1.
wget -c http://pecl.php.net/get/event-2.3.0.tgz -P /usr/local/src
2.
cd /usr/local/src
3.
tar -zxvf event-2.3.0.tgz && cd event-2.3.0
4.
/usr/local/php/bin/phpize
5.
./configure --with-php-config=/usr/local/php/bin/php-config
--with-event-libevent-dir=/usr/local/libevent-2.1.8/
6.
make && make install
三、在php.ini添加下面配置
1. extension=event.so;
重启php-fpm
