##安装完成之后，输出
Build process completed successfully
Installing '/usr/lib64/php/modules/xdebug.so'
install ok: channel://pecl.php.net/xdebug-2.4.1
configuration option "php_ini" is not set to php.ini location
You should add "zend_extension=/usr/lib64/php/modules/xdebug.so" to php.ini
##根据提示，我们在php.ini的最后添加
zend_extension=/usr/lib64/php/modules/xdebug.so
pecl install swoole
