详解基于Laravel8下的LaravelS实现高性能HTTP服务器
准备工作
虚拟生命：vm16
环境：LNMP
系统版本：CentoOS8.2
框架：Laravel8
我使用的测试环境大多数是基于最新版本，目的是用于测试学习。既然推出了最新的版本，不管你接不接受或愿不愿意使用，它都是一个趋势。因此，基于学习的目的，使用新版本。
关于环境的搭建不再重复了，博客里面写了源码安装搭建PHP环境。
什么是LaravelS
LaravelS 是一个胶水项目，用于快速集成 Swoole 到 Laravel 或 Lumen，然后赋予它们更好的性能、更多可能性。
创建Laravel8项目
第一步：安装Laravel8
composer create-project --prefer-dist laravel/laravel laravel_swoole
第二步：配置Laravel8虚拟主机
cd /usr/local/nginx/conf/vhosts/
# 注意：这个虚拟主机机配置Laravel8项目
vim laswoole.conf
注意：我这里是vhosts目录下。在nginx.conf文件中通过 include 引入vhosts 目录下所有配置文件
server {
listen 80;
server_name laravelswoole.com;
root "/www/laravel_swoole/public";
location / {
index index.php index.html;
autoindex off;
}
location ~ \.php(.*)$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
include fastcgi_params;
}
}
第三步：重启nginx
systemctl restart nginx.service
第四步：windows10本机配置hosts文件
192.168.157.129 laravelswoole.com
安装Laravel-s
第一步：安装Laravels
cd laravel_swoole/
# 安装
composer require hhxsv5/laravel-s
第二步：生成配置
php artisan laravels publish
Laravel5.5以上版本不再需要手动配置app.php了。此命令完成之后即可使用。
第三步：运行Laravel-S
php bin/laravels start

Speed up your Laravel/Lumen
>>> Components
+---------------------------+---------+
| Component | Version |
+---------------------------+---------+
| PHP | 7.4.11 |
| Swoole | 4.5.5 |
| LaravelS | 3.7.8 |
| Laravel Framework [local] | 8.11.2 |
+---------------------------+---------+
>>> Protocols
+-----------+--------+-------------------+----------------+
| Protocol | Status | Handler | Listen At |
+-----------+--------+-------------------+----------------+
| Main HTTP | On | Laravel Framework | 127.0.0.1:5200 |
+-----------+--------+-------------------+----------------+
运行之后通过 ip+端口即可访问，如192.168.157.129:5200
第四步：配置nginx
注意了，这里是为Laravel-S单独配置一个服务器。传统的配置是nginx接收到一个php请求后转发给php-fmp处理；实现高性能Swoole HTTP服务器，这里是将请求转发给LaravelS处理。
cd /usr/local/nginx/conf/vhosts
vim laravel_s.conf
upstream laravels {
server 127.0.0.1:5200 weight=5 max_fails=3 fail_timeout=30s;
keepalive 16;
}
server {
listen 80;
server_name laravel-s.com;
root /www/laravel_swoole/public;
index index.php index.html index.htm;
location / {
try_files $uri @laravels;
}
location @laravels {
proxy_http_version 1.1;
proxy_set_header Connection "";
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Real-PORT $remote_port;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header Scheme $scheme;
proxy_set_header Server-Protocol $server_protocol;
proxy_set_header Server-Name $server_name;
proxy_set_header Server-Addr $server_addr;
proxy_set_header Server-Port $server_port;
proxy_pass http://laravels;
}
}
第五步：重启nginx
systemctl restart nginx.service
第六步：windows10配置hosts文件
192.168.157.129 laravel-s.com
到这里就已经配置完成。配置基于域名之后，端口访问失败了。
说明：laravelswoole.com 是基础传统的HTTP服务器；laravel-s是基于Swoole。
性能测试对比
使用ab压力测试工具进行对比测试。
基于php-fpm的压力测试
ab -n 500 -c 100 http://laravelswoole.com
Server Software: nginx/1.18.0
Server Hostname: laravelswoole.com
Server Port: 80
...#省略
Concurrency Level: 10
Time taken for tests: 5.806 seconds
Complete requests: 100
Failed requests: 0
Non-2xx responses: 100
Total transferred: 52046500 bytes
HTML transferred: 52024900 bytes
Requests per second: 17.22 [#/sec] (mean)
Time per request: 580.583 [ms] (mean)
Time per request: 58.058 [ms] (mean, across all concurrent requests)
Transfer rate: 8754.41 [Kbytes/sec] received
...#省略
Percentage of the requests served within a certain time (ms)
50% 574
66% 587
75% 596
80% 607
90% 642
95% 668
98% 677
99% 686
100% 686 (longest request)
可以看到每秒处理请求是 17.22个。
基于swoole的压力测试
ab -n 500 -c 100 http://laravel-s.com/
Server Software: nginx/1.18.0
Server Hostname: laravel-s.com
Server Port: 80
...#省略
Concurrency Level: 100
Time taken for tests: 0.803 seconds
Complete requests: 500
Failed requests: 0
Total transferred: 9254500 bytes
HTML transferred: 8729000 bytes
Requests per second: 622.59 [#/sec] (mean)
Time per request: 160.620 [ms] (mean)
Time per request: 1.606 [ms] (mean, across all concurrent requests)
Transfer rate: 11253.38 [Kbytes/sec] received
...#省略
Percentage of the requests served within a certain time (ms)
50% 138
66% 144
75% 161
80% 167
90% 204
95% 229
98% 240
99% 244
100% 273 (longest request)
可以看到基于swoole服务器之后的处理请求数是622.59。
总结
从中可以看到基于swoole之后很明显的优化，处理请求数大大提高。php-fmp是17.22，swoole是622.59。差距非常大。
配置的过程中遇到了一些错误，主要是配置虚拟主机的错误，好在都解决了。如果你也遇到相似的问题，欢迎一起讨论学习。
