在执行path命令时出错，如下：
# patch -p1 < /home/tools/nginx-1.6.2/nginx_upstream_check_module-master/check_1.5.12+.patch
can't find file to patch at input line 5
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|diff --git a/src/http/modules/ngx_http_upstream_ip_hash_module.c b/src/http/modules/ngx_http_upstream_ip_hash_module.c
