nginx 配置禁止IP 访问网站

由于国内备案严格要求。很多童鞋都不会设置

在这里我 把我的实战过程分享给大家

错误一：

nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)
[root@localhost conf]# /usr/local/nginx/sbin/nginx -s reload
nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)
[root@localhost conf]# /usr/local/nginx/sbin/nginx -s reload
nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)
[root@localhost conf]# /usr/local/nginx/sbin/nginx -s reload
nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)
[root@localhost conf]# /usr/local/nginx/sbin/nginx -s stop
nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory)
重启nginx  或者停止都报错  

解决办法：

  /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

即可修复

然后使用  /usr/local/nginx/sbin/nginx -s reload

 问题2：禁止IP 空主机头直接打开网站

方法

打开 nginx.conf

vi /usr/local/nginx/conf/nginx.conf  

找到http  段

在开头加入

server {
listen 80 default_server;
server_name _;
return 444;
}
