目标描述

域名mall.test为访问域名，分别复制3个相同的thinkphp做负载均衡。

在nginx配置下定义转发分配规则

nginx.conf

http{
#访问域名
include       E:/wnmp/nginx-1.18.0/conf/config/tp6.xy.mall.test.conf;
#引入复制项目1Nginx配置
include       E:/wnmp/nginx-1.18.0/conf/config/load/mall7811.test.conf; 
#引入复制项目2Nginx配置
include       E:/wnmp/nginx-1.18.0/conf/config/load/mall7812.test.conf;
#引入复制项目3Nginx配置
include       E:/wnmp/nginx-1.18.0/conf/config/load/mall7813.test.conf;
     
       #定义转发分配规则
    upstream mall{
            server mall7811.test:7811;
        server mall7812.test:7812;
        server mall7813.test:7813;
    }
}

访问域名tp6.xy.mall.test.conf配置文件

server {
        listen       80;
        server_name  mall.test;
        location / {
            #解决项目下css,js,图片等静态文件不读取问题
        proxy_set_header Host $host:$server_port;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            #设置proxy_pass根据转发规则
        proxy_pass http://mall;
    }

三个项目文件与正常项目nginx配置文件无差别，只是本地区分的端口

server {
        #指定不同的端口
        listen       7811;
        server_name  mall7811.test;
        location / {
            root   E:/wnmp/www/load/mall7811/public;
            index  index.php index.html index.htm;
            autoindex on;
            autoindex_exact_size off;
            autoindex_localtime on;
            if (!-e $request_filename) {
        rewrite ^(.*)$ /index.php?s=/$1 last;
        break;
        }
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        location ~ \.php$ {
            root           E:/wnmp/www/load/mall7811/public;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
          #这里$document_root指的是上面定义好的nginx根目录：C:/wnmp/www
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
            if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
                set    $real_script_name    $1;
                set    $path_info    $2;
            }
        }
    }
