背景介绍
要理解swoole加速框架的原理，原因是传统php-fpm的工作模式及缺点造成。php-fpm是管理php-cgi的进程管理器，在每一次请求过来，都需要加载一次PHP的全部运行文件，处理业务，请求结束后就会释放内存，无法做连接池。这样一旦访问量多了，需要的系统资源开销很大，系统很可能承受不住。
而swoole是长驻内存的模式，长驻内存一个最大的好处就是可以性能加速，原因是内存的效率远高于磁盘。简单来说就是之前是每次请求进来都需要加载一遍PHP运行文件，而现在只需要在第一次请求进来时加载这些文件，然后驻留内存中，之后再进来的请求都可以直接复用内存中的内容。
安装swoole扩展不介绍，
1、安装laravel-swoole
composer require swooletw/laravel-swoole
3、在config/app.php的数组providers增加
SwooleTW\Http\LaravelServiceProvider::class
2、安装配置
修改端口9501
php artisan vendor:publish --tag=laravel-swoole
3、nginx反向代理
把url的请求转发到swoole服务地址127.0.0.1:9501
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
server
{
listen 80;
server_name www.xxx.com ;
index index.html index.htm index.php default.html default.htm default.php;
root /home/wwwroot/www.xxx.com/public;
location = /index.php {
try_files /not_exists @swoole;
}
location / {
try_files $uri $uri/ @swoole;
}
location @swoole {
set $suffix "";
if ($uri = /index.php) {
set $suffix ?$query_string;
}
proxy_set_header Host $http_host;
proxy_set_header Scheme $scheme;
proxy_set_header SERVER_PORT $server_port;
proxy_set_header REMOTE_ADDR $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
proxy_pass http://127.0.0.1:9503$suffix;
}
}
4、启动服务器
php artisan swoole:http start
