AMH5 下如何配置 Flarum 的 Nginx 伪静态？

安装的是 Flarum ，使用官方的伪静态规则

location / {
try_files $uri $uri/ /index.php?$query_string;
}

location /api {
try_files $uri $uri/ /api.php?$query_string;
}

location /admin {
try_files $uri $uri/ /admin.php?$query_string;
}

location /flarum {
deny all;
return 404;
}

location ~ .php$ {
fastcgi_split_path_info ^(.+.php )(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}


然后直接 502 了，报错：

2015/08/29 09:06:21 [crit] 26106#0: *5153 connect () to unix:/var/run/php5-fpm.sock failed (2: No such file or directory ) while connecting to upstream, client: 117.30.61.168, server: www.****.com, request: "GET /admin HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "www.****.com", referrer: "http://www.****.com/"

这个该如何解决？
