192.168.55.115为主服务器

192.168.55.185为从服务器

先需要将发送到服务器端的请求进行分流，具体要求如下

要求/index.php/\*的请求访问主服务器

/api.php/1/files/\*的请求访问主服务器

/api.php/1/files\_put/\*的请求访问主服务器

/api.php/1/thumbnails/\*的请求访问主服务器

/statics/thumbnails/\*的请求访问主服务器

其它的都访问从服务器

主服务器192.168.55.115的server配置

upstream follower  {
          server 192.168.55.185:80 max_fails=5 fail_timeout=360s;
    }
    
    server {
            listen       80;
            server_name  192.168.55.115;
            index index.html index.htm index.php;
            root /www/web/sign_name;
            client_max_body_size 10240m;
    
            location ~ ^/index\.php\w*|/api\.php/\d+/(\bfiles\b|\bfiles_put\b|\bthumbnails\b)/\w* {
                    set $script $uri;
                    set $path_info "";
    
                    if ($uri ~ "^(.+.php)(/.+)") {
                            set $script $1;
                            set $path_info $2;
                    }
    
                    fastcgi_pass   127.0.0.1:9000;
                    fastcgi_index  index.php;
                    fastcgi_param  SCRIPT_FILENAME  /www/web/sign_name$fastcgi_script_name;
                    include        fastcgi_params;
                    fastcgi_param  SCRIPT_NAME $script;
                    fastcgi_param  PATH_INFO $path_info;
            }
    
            location ~ ^/statics/thumbnails/\w* {
    
            }
    
    
            location / {
                    proxy_pass  http://follower;
                    proxy_set_header Host $http_host;
                    proxy_next_upstream     error timeout invalid_header http_500;
                    proxy_connect_timeout   360s;
    
                    #rewrite ^(.*?)api.php/(.*)$ $1api.php?$2;
                    #rewrite ^(.*?)index.php/(.*)$ $1index.php?$2;
            }
    }

其中

set $script $uri;
                    set $path_info "";
    
                    if ($uri ~ "^(.+.php)(/.+)") {
                            set $script $1;
                            set $path_info $2;
                    }的设置是为了配置php的$_Server[''path_info"]获取了全路径的问题， 具体请参考
