一波三折。

1. 首先下載swoole安裝包（由於我這裏php是7，所以說應該去官網下載最新的swoole包，否則會發生意想不到的錯誤）

   wget https://github.com/swoole/swoole-src/archive/v1.9.16.tar.gz
   

2. tar -zxvf v1.9.16.tar.gz
   cd swoole-src-1.9.16/
   /usr/local/php/bin/phpize
   ./configure --with-php-config=/usr/local/php/bin/php-config
   make && make install
   

3. 　在php.ini加入swoole擴展配置

[swoole]
extension = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/swoole.so"

php swoole擴展安裝
