注意：

情况1：

当后端是独立的php-fpm服务器模块的话

需要fastcgi协议

情况2：

当后端是LAMP的话，使用的就是Apache协议

不需要开启fastcgi模块

直接写个location / {

proxy_pass http://backservers;

}

即可

此次实验安装的Nginx中fastcgi_params不适用此次，所以需要更该：

fastcgi_params模块内容：

fastcgi_param GATEWAY_INTERFACE CGI/1.1;

fastcgi_param SERVER_SOFTWARE nginx;

fastcgi_param QUERY_STRING $query_string;

fastcgi_param REQUEST_METHOD $request_method;

fastcgi_param CONTENT_TYPE $content_type;

fastcgi_param CONTENT_LENGTH $content_length;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

fastcgi_param SCRIPT_NAME $fastcgi_script_name;

fastcgi_param REQUEST_URI $request_uri;

fastcgi_param DOCUMENT_URI $document_uri;

fastcgi_param DOCUMENT_ROOT $document_root;

fastcgi_param SERVER_PROTOCOL $server_protocol;

fastcgi_param REMOTE_ADDR $remote_addr;

fastcgi_param REMOTE_PORT $remote_port;

fastcgi_param SERVER_ADDR $server_addr;

fastcgi_param SERVER_PORT $server_port;

fastcgi_param SERVER_NAME $server_name;

ab -n 1000 -c 100 http://192.168.253.100/cwy/

测试并发量

测试MySQL连通性：

$conn = mysql_connect('127.0.0.1','root','');

if ($conn)

echo succ;

else

echo fail;

mysql_close();

?>

使用的是Apache协议：

location /up/ {

proxy_pass http://cwy/;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

}
