Nginx的版本号隐藏

Nginx的版本号相关

隐藏版本号

nginx隐藏版本号需要将主配置文件中server_tokens关闭

server_tokens off;

查看头信息

[[email protected] ~]# curl -I  www.mylinuxops.com
HTTP/1.1 200 OK
Server: nginx           #现在已经不显示nginx的版本号了

彻底隐藏server信息

如果需要彻底的隐藏server信息，连nginx都不显示就需要修改源码
将源码包内的ngx_http_header_filter_module.c文件进行修改
1.修改源码

[[email protected] nginx-1.14.2]# vim src/http/ngx_http_header_filter_module.c
#static u_char ngx_http_server_string[] = "Server: nginx" CRLF;
static u_char ngx_http_server_string[] = "Server: " CRLF;
#将此文件内的第49行中的server之后的部分全部删除，然后重新编译

2.检查编译环境及工具

[[email protected] nginx-1.14.2]# ./configure --prefix=/apps/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre --with-stream --with-stream_ssl_module --with-stream_realip_module --add-module=/root/echo-nginx-module

3.生成相应模块并复制模块到指定目录

[[email protected] nginx-1.14.2]# make && make install

4.启动服务

[[email protected] nginx-1.14.2]# systemctl start nginx

5.再次查看头信息

[[email protected] nginx-1.14.2]# curl -I www.mylinuxops.com
HTTP/1.1 200 OK
Server:             #server信息已经彻底的隐藏
