负载均衡入口服务器配置
入口

#遇到502、503、504等状态码时，我们可以改变将之成200，这样在调用接口时，就可以正常的返回信息，给用户提供良好的交互环境。
error_page 502 503 504 =200 /dealwith_502?callback=$arg_callback;
location /dealwith_502{
#下面这些header，是为了防止跨域问题

if ( $arg_callback != "" )
{
return 200 'try{$arg_callback($ret_body)}catch(e){}';
}
return 200 $ret_body;
}

服务器1
server

#listen [::]:80;
server_name 149.129.114.100;
index home.html index.htm index.php default.html default.htm default.php;

error_page 502 503 504 =200 /dealwith_502?callback=$arg_callback;
location /dealwith_502{
add_header 'Content-Type' 'application/json; charset=utf-8';
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Headers' 'Origin, X-Requested-With, Content-Type, Accept';
add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT';
set $ret_body '{ "status": 0, "info": "系统繁忙，请稍后访问", "data": [] }';
if ( $arg_callback != "" )
{
return 200 'try{$arg_callback($ret_body)}catch(e){}';
}
return 200 $ret_body;
}
location / {
if (!-e $request_filename) {
rewrite ^(.*)$ /index.php/$1 last;
break;
}
}
location ~ [^/]\.php(/|$)
{
# comment try_files $uri =404; to enable pathinfo
#try_files $uri =404;
fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_index index.php;
include fastcgi.conf;
include pathinfo.conf;
fastcgi_param PHP_ADMIN_VALUE "open_basedir=/home/wwwroot/:/tmp/:/proc/";
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
expires 12h;
}
}
其他服务器配置和服务器1的配置是相同的，这样就可以避免高并发的出现。我做的项目就是这样处理的。
