nginx -t successful了，但是为啥还访问不了啊

求教

必须要reload ，配置文件才会生效

防火墙关没？

还要 /usr/local/nginx/sbin/nginx -s reload重启nginx
同时防火墙要设置好打开80端口 vi /etc/sysconfig/iptables
设置成这样:
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEP
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
最后 重启防火墙
/etc/init.d/iptables restart
