wget -c http://pecl.php.net/get/event-2.3.0.tgz -P /usr/local/src cd /usr/local/src tar -zxvf event-2.3.0.tgz && cd event-2.3.0 /usr/local/php/bin/phpize ./configure --with-php-config=/usr/local/php/bin/php-config --with-event-libevent-dir=/usr/local/libevent-2.1.8/ make && make install
- 在php.ini添加下面配置
