服务器 nginx 配置

配置 nginx 启动成功了，然后再服务器上通过 curl http://127.0.0.1 命令访问可以正确访问到 nginx ，但是在服务器上通过 curl http://服务器 ip 地址 报却访问不到，会超时，请问各位碰到过这样的问题吗
nginx.conf 配置如下
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
worker_connections 1024;
}

http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

access_log /var/log/nginx/access.log main;

sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 4096;

include /etc/nginx/mime.types;
