安装相关扩展

pecl install xdebug
##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

问题

configure: error: Cannot find php-config

在/usr/bin下执行 ln -s /usr/local/php/bin/php-config php-config 即可

卸载

php.ini 中删除 extension=swoole.so

卸载,切换到PHP安装目录下的bin

./pecl uninstall swoole(已swoole为例)
