配置Nginx隐藏版本号

修改配置文件法

[root@www conf]# vi nginx.conf
.....
server_ tokens off;              //关闭版本号
.....
[root@www conf]# nginx -t
[root@www conf]# service nginx restart
[root@www conf]# curl -| http://192.168.9.209/
HTTP/1.1 200 OK
Server: nginx

配置实例

[root@localhost nginx]# curl -I http://192.168.144.133/    //使用命令查看版本号
HTTP/1.1 200 OK
Server: nginx/1.12.2      //显示版本号

修改Nginx用户与组

编译安装时指定

修改配置文件法指定

[root@www conf]# vi nginx.conf
user nginx nginx;
[root@www conf]# service nginx restart
[root@www conf]# ps aux | grep nginx
root     130034 0.0 0.0 20220 620 ?        Ss 19:41 0:00 nginx: master process
/usr/local/sbin/nginx
nginx       130035 0.0 0.0 20664 1512 ?     S 19:41 0:00 nginx: worker process

配置Nginx网页缓存时间

设置方法

示例

location ~\.(gif|ipg|jepg|png|bmp|ico)$ {
       root  html;
       expires 1d; 
}

配置实例

[root@localhost ~]# systemctl stop firewalld.service      //关闭防火墙
[root@localhost ~]# setenforce 0                          //关闭增强性安全功能
[root@localhost ~]# systemctl start nginx.service         //启动nginx服务
[root@localhost ~]# netstat -ntap | grep 80               //查看服务端口是否开启
tcp        0      0 0.0.0.0:80              0.0.0.0:*           LISTEN      1684/nginx: master  
[root@localhost ~]# mkdir abc
[root@localhost ~]# mount.cifs //192.168.100.10/lamp-c7 abc/    //将宿主机图片文件夹挂载到abc目录
Password for root@//192.168.100.10/lamp-c7:
