从0到1搭建基于swoole的websocket服务

​

源码安装

wget  https://github.com/swoole/swoole-src/archive/v4.5.7.tar.gz
tar -xzvf v4.5.7.tar.gz
cd swoole-src-4.5.7 && \
phpize && \
./configure && \
make && sudo make install

启动扩展，需要在 php.ini 中加入如下配置来启用 Swoole 扩展

extension=swoole.so

验证是否配置成功

php -m |grep swoole

如果没有可能是 php.ini 的路径不对。
可以使用 php --ini 来定位到 php.ini 的绝对路径，Loaded Configuration File 一项显示的是加载的 php.ini 文件，如果值为 none 证明根本没加载任何 php.ini 文件，需要自己创建。
