PHP7下安装event扩展

前言：

有效安排I/O，时间和信号的扩展，使用可用于特定平台的最佳I/O通知机制的事件，是PHP基础设施的libevent端口。（目前PHP7不支持libevent）

安装主持库libevent，需要编译高版本

[root@localhost ~]# 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
[root@localhost ~]# cd /usr/local/src
[root@localhost src]# tar -zxvf libevent-2.1.8-stable.tar.gz && cd libevent-2.1.8-stable
[root@localhost libevent-2.1.8-stable]# ./configure --prefix=/usr/local/libevent-2.1.8
[root@localhost libevent-2.1.8-stable]# make && make install

安装event库

[root@localhost ~]# wget -c http://pecl.php.net/get/event-2.3.0.tgz -P /usr/local/src
[root@localhost ~]# cd /usr/local/src
[root@localhost src]# tar -zxvf event-2.3.0.tgz && cd event-2.3.0
[root@localhost event-2.3.0]# phpize
[root@localhost event-2.3.0]# ./configure --with-php-config=/usr/local/php7/bin/php-config --with-event-libevent-dir=/usr/local/libevent-2.1.8/
[root@localhost event-2.3.0]# make && make install

# 修改php.ini配置文件，添加如下：
extension=event.so

重启php-fpm，查看php -m 查看event库是否安装成功！
