当我执行sbin/nginx -t 出现下面的问题，虽能帮我解决。

我在cloudfoundry/.deployments/devbox/deploy/nginx/nginx-0.8.54/conf/nginx.conf 配置如下
server {      
listen       443 default ssl ;      
server_name  localhost;   
if ($server_port = 443) { set $https on; }   
if ($server_port = 80) { set $https off; }      
  ssl                  on;        
ssl_certificate      /var/vcap/ssl/cfsupp1.crt;      
ssl_certificate_key  /var/vcap/ssl/cfsupp1.key;      
  rewrite ^(.*) http://domain.com$1 permanent;      
ssl_session_timeout  5m;      
ssl_protocols  SSLv2 SSLv3 TSv1;        
ssl_ciphers  ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;      
ssl_prefer_server_ciphers   on;}
执行下面的语句出现错误：
root@cf001:~/cloudfoundry/.deployments/devbox/deploy/nginx/nginx-0.8.54# sbin/nginx -t
